Oil leaks (lots of pictures in here if you are on slow internet)

[Epic_Dragon]

I am trying to figure out where my discovery is leaking from. At first I thought it was leaking from the trans somewhere. But after intense degreasing, and watching like a hawk, I cannot find any transmission fluid. However, it looks like somewhere around the transfer box, and up the front of the auto trans area, which seems to be engine oil. Coming from somewhere on the passengers side. Also looks like front diff is leaking a bit as well, but that could just be run off from the leak mentioned above. Oil seems to spread a long way! I do not like my baby leaking! But no idea where to start in fixing it. Looks like may have been leaking for some time as lots of caked on oil around. Most of which i managed to clean off when degreasing. Engine oil is at least easy to keep topped up. The other is a bit harder.

Some photos of roughly where it seems to be all coming from.

Hi!

The engine oil leak could be a loose spin on filter, this is surprisingly common :(, or the turbocharger return line flange gasket where it bolts under the turbocharger.
The transfer case leak is very likely the intermediate shaft O rings, or the input seal. Again, a very common sight.
The rear of the transpan looks suspect, too. A service kit will sort that out, also give you a chance to check the trans oil and filter condition. The other possibility is the rear extension housing gasket where it meets the main case. Seen a few leak there, too.

JC :)

[Epic_Dragon]

thanks :) hopefully the engine oil leak is one of those common things.
yeah it is a bit suspect at hte back of the transpan there, i checked trans fluid levels and very full, and looks a good colour. shot out at me with force! think it might be over full? I topped up the transfer box as levels were low. I think that leak will be first on my list. Service kit sounds like a good place to start.

[justinc]

Trans fluid level is a bad thing if it is very high. Was it running in park or Neutral, on level ground?

I'm Sure you'll sort it out L :) You'll need a T27 Torx bit to remove the filter assembly, doing a trans service is quite a bit easier in the D2 than the D1, which is good:D.

[Epic_Dragon]

it was on level ground, and not running. i know wiht a dip stick they are supposed to be checked when the car is running. but not sure with this filler plug thing. LOL.

haha easier is good :) least with the disco being so high i can get under it easy to use my feet undoing things!

[justinc]

yes, same deal as a dipstick model, you can overfill these slightly by 500ml or so and won't hurt.

pm sent:)

[robbotd5]

Give it a good steam clean and then run the car, leaks are much easier to detect that way.

[Epic_Dragon]

given it 2 good cleans now to sus the leaks. narrowed it down a lot.

god its an incredible vehicle though LOVE it!

[lavingia]

I had the same symptoms on my D2. Turned out to be diesel leaking from the fuel pressure regulator. Its also just above the auto and hard to see and get to. Found it when i went under the car while it was running with a LED flash light.

Are you sure its oil thats leaking ?

[gusthedog]

Does look more like diesel than oil. I'm with lavingia - fuel pressure reg.;)

[Epic_Dragon]

it feels like oil, but then i guess diesel actually feels oily too. I will have a look closer and see cheers :). quite possibly! I solved a friends oil leak, which is good. just got to get to bottom of mine now. been too hot today for me to do anything though :(

[Epic_Dragon]

no one in SA happens to have a pit or hoist they wouldnt mind letting me use to have a good look do they? LOL

[lavingia]

I used a couple of car ramps and got the car on them at the front. That was enough room to get under the car.

[Epic_Dragon]

yeah was thinking of car ramps, i dont have access to any at the moment, but might try save up over next couple of weeks and buy a set

[Roberto]

ED, mine looks very similar. I just had it serviced last week in Canberra and specifically mentioned to check the oil leak. Anyhow, I made it back to Echuca OK. The leak is so profuse it sprays the trailer. In particular, I have those drops forming on the transfer case inspection plate bolts like you do. I think if it were diesel it would evaporate after being in the hot sun. It feels thicker than diesel. I was thinking it came from the transfer case. Lying on my back with oil dripping into my eyes makes it hard to do much. The TC filler plug looks difficult to access, and once removed I'm not sure how to check fluid levels. I note from the manual that it holds 8 pints. Lets know how you get on. Meanwhile, can anyone recommend a good mechanic in either Melbourne or the North Country region?

[Epic_Dragon]

i dont think it is the fuel pressure reg, is engine oil im pretty sure. looks to be behind oil filter/ rocker cover gasket just above there. is a hard spot to really see well though.
i think it is the input shaft seal leaking on my transfer case. i think it needs to just dribble out of the filler plug if it is the right level. i got to mine with a half inch drive extension and used my feet on the ratchet. was tricky but you will have no hassles with good hands getting to it. getting the fluid in was harder as i dont have the pump thing designed for the job haha

[Epic_Dragon]

slowly narrowing down the oil leaks.
one is this, easy to get to at least.

and the rest well, it had a super good clean/degrease. driven 3 times since, just short distance about 25kms round trip. it doesnt look to be the oil filter, it seems to be somwhere behind it. if anybody can shed some light on what this might be and how i can start to fix it, please help LOL. it is progressively getting worse.

and transferbox leaking both trans oil and diff oil LOL. yay!!!! the trans fluid leak faster than the diff oil one.

[SiddersC]

Front cam seal is easy, less than 5 minutes, pop out, clean and install new

The oil filter housing could be leaking from behind?, bit hard to see

When you remove you exhaust manifold to fix your broken studs you will have a clearer picture.

The trans will be leaking from the output shaft and the transfer will be leaking from the input shaft or the intermediate shaft, either way the transfer has to come out for a reseal.

I hear good things about Shepp 4 wheel drive centre.

[Epic_Dragon]

wow i do have broken studs. did not actually notice them, too busy looking for the oil leak, i thought something looked odd there but had not placed it yet. they are going to be a real pain to get out LOL

[bee utey]

Hi ED, I have car ramps at Crafers, you can use them here and I can have a look too if you like. I'm not particularly interested in fixing oil leaks though! I can get some parts sent here if you need, I have a few trade accounts. PM me if you want to come this way.

[JackH]

Have you checked the rocker cover gasket. I had oil leaking at the rear of the motor and running down underneath and that's what it was. Just a thought.

[Epic_Dragon]

thanks beeutey, might take you up on that. just a point in the right direction is good.
i thought rocker cover gasket too but doesnt seem to have any leaks from there, its lower. right in line with the oil filter lol. but not the oil filter.

[Tombie]

Most like gasket behind the oil filter.

At least when you take the exhaust manifold off to fix the studs you'll have easy access to the oil filter and cooler housings so you can replace the gaskets. Who said land rovers where hard to maintain? :cool:

[Epic_Dragon]

hehe there is a lot of heart in these cars :) im yet to find a landy driver who hasnt got some sort of cheesy grin on their face when behind the wheel haha! othe than the really rich ones who have the fancy range rovers that arnt actual landrover lovers but its a status symbol haha i dont think they know how to crack a grin :D only met 1 like that!
i plan to do it all at once i think. i will do the camshaft one through the week, then put my engine cover back on. and keep eye on oil levels for a few weeks. might have a transfer box already i can just put a service kit thing through and bolt back in. if not ill jsut get that out when its off road to get the other bits done. i need it to move my yearling horse back home. then will fix the leaks haha. well i use the term fix loosely :D

[clubagreenie]

I do not like my baby leaking!

And you bought a Land Rover?

[Epic_Dragon]

haha yes! now i know more of where its coming from is not so scary :) haha i do not like it leaking no! and i will stop it leaking ;) you watch, first landy in history it will not leak!!!! :P

[clubagreenie]

I'm buying shares in dow corning. Silicon sales set to skyrocket.

[OffTrack]

haha yes! now i know more of where its coming from is not so scary :) haha i do not like it leaking no! and i will stop it leaking ;) you watch, first landy in history it will not leak!!!! :P

Don't believe 'em. "All Landies Leak" is the motto of people who can't be stuffed looking after their vehicle properly.

A leak free D2 is perfectly achievable with a bit of TLC.

[djam1]

Paul I agree a leak proof later model is quite achievable.
A leak proof series ummm NO!! not without profound dedication and patience.

Mine leaketh not :D

Excuses, excuses :D My old man manages to put together 1920's and 1930's vehicles that don't drop oil.

My D2 is currently has a small oil patch on the sump gasket, but it's not currently enough to do more than dampen the sump flange. I've got a gasket ready to do change but have been a bit slack. :angel:

The TC case has a dusty/oily patch at the top rear near the PTO cover that doesn't seem to get any worse. The TC has to come out as it's getting pretty noisy and had a lot of metal in the oil at last change 20K km ago.

There is also a mystery oil leak that is wicking up the auto harness into the wiring behind the handbrake that I need to sort.

In the D2's at least a leak is a pretty good indicator that something needs attention.

cheers
Paul

[Epic_Dragon]

haha oh my god my dad is getting in on this now, he says a leak free landrover is a nissan :P hahah yet, he day dreams and longs for a defender hahaha. think my dad is in denial haha. he is a landrover fan, steals my disco whenever he gets the chance "fakes" his car injuries in order to borrow my beasty! haha

Young dragon...

Possible parts list for you to repair your leaks.

Cam cover gasket LVP000020
Oil filter housing gasket LVH100230
Oil drain gasket LRJ100000
O ring oil cooler hsg ERR7098
Oil cooler gasket ERR7220
Exh manifold gskt LKG100470
Turbocharger gskt ERR6768
Exh flange gskt ESR 3737

Standard exhaust manifold studs and nuts are readily available, but consider upgrading to M10 (from M8 std).

Use a high quality sealing compound on the gaskets where necessary.

A bit fiddly, but about a 3 hour all up job. And you might need that exhaust manifold faced flat.

[Trippy]

Do you guys get the parts number from microcat? Can I access microcat somewhere or do you need a subscription?

[Pierre]

Yes - check out the shop.

[Trippy]

Yes - check out the shop.

Aha, is it this one?: Dave's Interesting Things - LREPC01 (http://www.davesitshop.com/davesitshop/index.php?_a=viewProd&productId=5)

[Pierre]

'Tis indeed! While you're there, get the RAVE 2 for your D2.

I use the software on an old 32 bit notebook. All up, about $80. Naughty, but nice.

Pete

[Epic_Dragon]

thanks pierre :) i am a bit concerned with getting that manifold off, not sure how to get into it. dad has tools to get out broken bolts but weather or not tool easy to get in, but then pulling other bits off might make it easier to get to. will prbably take me a good week if i manage at all with my disabilities. but going to give it a dam good shot after i collect bits i need. have been recommended the M10 upgrade. thought about facing as well.
thanks again :) checking out daves interesting things!
also thought i had my sisters broken freelander sussed but evidently not :( silly thing misfiring at 2000 rpm!!

[SiddersC]

Removing manifold is easy enough, the studs may be a different story though

[Epic_Dragon]

well finally got round to ripping off the warped manifold. i have a few broken studs! and it seems my 'oil leak' is actually the oil that runs through here from the turbo coming out of the warped/blowing part of the manifold! so hopefully this is two birds with one stone getting fixed! it explains why with all the oil everywhere, the engine oil levels actually never drop! also found 2 bits where coolant is seeping from in moving a hose in the way!
manifold is going to get machined and i will remove the webbing. I think i read somewhere too, that the end stud holes on the manifold should be made larger to allow for expanding of the manifold and prevent further cracking/warping?

I also have one other issue, the 40 amp fuse in the engine bay that says for 'cooling fan' keeps blowing. my wiring all looks fine. anybody had any similar issues with this particular fuse blowing? it must be shorting out somewhere as it is instant.

the photo is before all the studs were removed, and its all cleaned up now ready for manifold to go back on. there are 3 broken ones to drill out though still.

[Cobber]

You've dug this out of the archive! :D

Glad you've got it all off and are in the process of sorting it :BigThumb:

Not sure about the fuse ... could it be a poor earth? :confused:

[Epic_Dragon]

haha yep, figured easier to update this one than start another thread haha.

i suspect fuse is a poor earth, jsut got to find it. its probably loose so it shorts LOL! the car is running as normal though with the fuse blown. so its weird haha
