I believe item 1.

I have a 95 Land Cruiser, the I6 headgasket had a flaw that failed at 170k. Even when Toyota f00ks up the damn thing runs forever. I spent 3k to r&r the hg/all teh while you are in theres and it now has 220k & runs like new.

My 2002 4.6is engine look just like the OP's engine, always wet in the bottom front. So where do the oil leaks come from on the E53 V-8 engines?

I did mine chain when the timing cover leak got from a drip to drops on the garage floor.

Do you have a leak on the big PS hose running across the engine. I did that 2X. The 1st time was somewhere around 80K or so. The 2nd replacement hose went bad in less than 1.5 years

Was able to spend a little time after work getting some stuff done.

Pulled exhaust mid section. This was much easier than I thought. None of the bolts were frozen and the section just came right out.



I wasn't sure what the rear mufflers were going to do, but they just stayed put.



Shot at the belly with the exhaust gone.



Another angle



Here's the fuel line disconnected and plugged



Got the engine support bar and test fitted it. I wish it was longer so that it would rest on the fenders instead of the valleys. There's not really enough room to fit the engine balance bar in there the way it is now.

I'll play with it some more once I get all the wires pulled off the top of the engine.



Updated parts list. I think I have all the part numbers now except for misc O-rings and replacement bolts.

Very nice progress!

Thanks BigBlack! Keeping fingers crossed the tear down will continue to go smooth, and the replacement of parts!

Went ahead and priced the parts. Mostly from realoem, but also checked eBay vendors where there was a significant savings. Here are my findings thus far:

I have been having really good luck with bmwpartsupply.com - they are out of California which seems wacky but I have had several larger parts shipped for their standard $15 shipping fee and they have been significantly lower than my local stealer on every single part. Order status and shipping updates are timely and I have called them to fix a screw up I made - they were very accommodating.
