Thread: What happened to your D3/D4 today?

That number should be 1316063 for the 2.7 D4, ie without the LR prefix.

The drivers side intake manifold inlet and the throttle body is choked up with gunk from the EGR. So will clean this up as well.

Unfortunately hit the dreaded 3D puzzle of removing the crankcase vent oil separator before running out of time today. So will continue another day.



(Last photo from LR Time - thanks for the diagram Vera - it looks fairly accurate!)

Getting oil in the coolant ?

No - just a glutton for punishment doing the oil cooler proactively. Figured 15 years is a good time to replace.

All the rubber cooling system hoses will need to be next…..(not looking forward to this).

You’ll also find all of the plastic shields on the wiring disintegrates into fine shrapnel so be careful to get that out and a good time to replace with harness cloth tape. Make sure those vertical bolt holes don’t have coolant trapped in them when you put the bolts back.

The worst ones I’ve done have been the EGR cooler hoses. I think I spent 4 hours getting the passenger side intake hose on. Other than that the coolant intake for the block looks like a sod.

My biggest issue is the price of the Medusa wig of hoses.

So, in confirmation, is this correct:?

2.7 is p/n LR013165
3.0 is p/n 1316063

Thanks.

You are not wrong. I have harness cloth tape all ready to go and I am constantly vacuuming up any small broken bits.

I have a lot of cleaning to be done before I even remove the oil cooler. Oil vacuum extractors are great for sucking up any moisture and small bits as well.

With the oil separator - can you get the rear seal where the oil is returned? I have the two smaller front ones for the legs where the crankcase gases are extracted, but could not find a part number for the seal at the back. Is this even replaceable?

Very strong argument for doing a body off mid-life at some stage. Just need a workshop and 2 post hoist.
