SubscriberHey Guys,
A few months ago I purchased a '97 300tdi D1 with 270kms. The bloke sold it because it had water in the oil. Having discovered it had both water in the oil and oil in the water and that it blew heaps of smoke and overheated I suspected a blown HG so I pulled off the head and got it checked. Result? Even though I was assured by the owner that it never had been hot it was warped and soft. So I bought a brand new one. The head gasket was so destroyed that even my local head mechanic couldn't decode it! Meanwhile I tried to get the radiator checked, shop wouldnt touch it as it was too fragile with age and corrosion! So I whacked on the new head, changed the oil (12 ltrs of white cream came out, yes I know it only takes 6.7 ltrs but...) and flushed the cooling galleries as best as I could. Started and ran beautifully except that the oil turned creamy again. Having thought maybe I hadnt diluted the old oil and cleaned the oil galleries enough I changed it again. Turned creamy after ten mins or so running. And the oil level was rising indicating that water was getting in plus I had oil rising to the surface in my thermostat housing. Suspecting the oil cooler in the radiator I swapped it out for one I know was not leaking and tried again. Result was better with only a tiny bit of water in the oil which we put down to leftover oil in the filter etc. After some short test runs I got it nice and warm, dropped the oil while it was nice and thin, emptied the oil filter, and filled it up again. A test run came back all good so it was taken on a short 15-20 min run to the shops and back. Inspection this morning shows I have about 4 times the required amount of oil on the dipstick AND its all white!I really need some help here as I have no idea what I can do next as I've spoken to several Landy mechanics and they all said cracked blocks are extremly unusual as was also indicated by frequent googling and many painful, extensive Aulro searches!
Crack testing the block wasn't an option when I took the head off as it would have had to come out and be stripped. So the head is good, the radiator is good, where else other than the block can oil and water mix? And as the oil pressure is alot higher than the water it's a little strange it can get in at all.
Any ideas would be appreciated greatly?
Thanks,
Lane

it usually gets in at the oil cooler, its not under a lot of pressure, to isolate it go to a hydraulic shop and get a blanking hose made up with the same fittings as whats on the radiator OR remove both the pipes from the engine and explain carefully that you want to fit a loop hose in its place and will need the same fittings as whats on the pipes. Dont let them put the fixed fittings on or you'll get one side wound on but not the next.
If you have a cracked water cooled turbo it can get in there.
if the head assembly has not been done correctly the coolant can leak into the oil galleries but usually you also get it coming out the side of the block.
I have seen one case of the timing cover not being on correctly and the water pump leaking into the timing case but it was also leaking off the engine. The owner on this one knew of the coolant leak and had just kept topping it up.
Internal bore damage can do it especially if the damage is below the low point of the bottom ring.
Thats about all I can think of thats not got other major inicators.

Blknight I have got a fresh radiator just back from the shop which was pressure tested to 25psi and they said no leaks so I'm sure its not the oil cooler, my turbo is original and not watercooled, I've done many heads including a 300tdi so I'm pretty sure I did it correctly - it has the same fault as before I changed it. I think the cooking of the head would have happened from water loss into the oil. Haven't touched the timing, and the bores looked good all the way down as far as I could see. I have no exterior leaks on the engine.

Head gaskets dont always have to let go from cylinder to somewhere else they can fail jacket to jacket.
I have seen a tractor engine that had rotted out a thin spot in the jacket casting inside the block.
The only other place it could be leaking coolant into the oil is via the head if it had a crack in it somewhere other than the combustion chamber. My next step would be to get the thing warmed up, dump the oil drop the pan remove the oil cooler lines then pressurise the cooling system as you take the rocker cover off. That'll give you a tracable line on the leak.

Well I'm sure it isn't cracked. I think it must be the block somewhere. It's leaking vast quantities of coolant into the oil, you can see the dipstick level rise after a minute of running.

I'm thinking left field here but you said it improved when oil cooler was replaced. Why can't the second hand one not fail too maybe bypass it for a week and see if it stops.
