Thread: URGENT HELP NEEDED FOR LR90 on Route

I would be giving these guys a call I have aways found them good with phone questions and have freight all over the place. My Dad in melbpurne needed some stuff and they sent it to him cheaper that what he could get it in Melbourne.

Did anyone tell you to get an Isuzu?
One of them would haul real well in a ninty.

Thanks all for feedback and comments. Have established camp at Gundy and set about some open heart surgery on the 90.

First things first was to try and establish which of the pistons might have cracked a ring with a compression test we headed of into town to track down a diesel mechanic. 4 workshops and a few phone calls later, no one had a adapter for either the glow plugs or the injectors....while everyone was very friendly (just like the sign into town promised!) no one was really very helpful, not wanting a bar of this Land Rover engine.

Using a technique given to me by Blknight, we pressurised the cylinders through the glow plug hole and tried to establish which is any was allowing compressed gas through into the crankcase and spurting oil out of the dip stick etc. We could not establish anything definitive, and not being left we many options rang about to see where we could get a head gasket and rings..since we figured it was time to pull off the head and have a look...luck would have it that both MR Automotive and Four Wheel Drives both have parts, MR being closer got the order for a upper gasket set and set of STD rings.

Next was establishing a bush workshop at some camping grounds near the outskirts of town (and handily close to the CAT workshop)

We then set about removing all the bits that get in the way, like the injectors. Noticed oil around the bases....is this meant to be there?

Then out came the bolts. Boxes are useful to store them in the right order

Out comes the head

Inside one of the cylinders. Cross hatching still evident. Slight score on the bore - essentially wiped it off - a sign of things to come? Could not feel any cracks other than those that are meant to be there in the rings with the feeler gauge, but a large lip of carbon was noted

What does tomorrow bring? Looks to be removing the carbon lip and seeing what it is hiding. Dropping the pistons and seeing what has happened to the rings. Checking the head, since some fractures were noted around the pre-combustion chambers - not a good sign either.....

You should have someone video everthing and make a doco.
I know a bloke if you interested.
I am sure the poms would watch somthing like that.

Sorry to hear about your troubles James, hope you can get it sorted okay.

Gill said do you want help from Neville

Did mr get the parts out same day?

How's the food going, do you need a air-drop

We are filming as much as we can, we only have a little handy cam...and we got some good time-lapse of taking off the head yesterday with the gopro. I guess that is something positive!

MR said the parts should arrive with them today....and they would send them ASAP. But it looks like the weekend will get in the way and delay things a little.

Juddy - still got plenty of food left...at least 2 more meals from Gills stash she cooked up. We hijacked the freezer in the caravan park The curry was delish!

Slight cracking on the pre-combustion chambers and even on the injector nozzles is normal (unfortunately!).

Those vertical lines in the cylinder look ominous... Which cylinder was that?

not too worried about the vertical lines on the bores thats going to be from the ring gap from the first and second compression rings Im more worried about the amount of oil thats up past the rings and the fouling on the bore....

from my 2.25 manual....

the clearance limits for the diesel piston to bore is .111mm (44 thou) to .134mm (53 thou)

for over size its .111 to .157mm (44 to 64 thou) the tighter tolerance I quoted you on on the phone is for petrol engines.

did you want me to scan in the rebuild instructions from my 2.25 workshop manual and did you want me to send you any of the specialist measuring tools or the bottle brush bore hone?
