Pulling and examining a 2JZ this weekend, trying to find internal damage and find root cause of poor performance and oil in the cylinders. Boosted IS300, probably burned the rings

 

Not to hijack the thread, but ring failure on a boosted 2JZ is unlikely. If it has the stock head bolts, it probably lifted the head and popped the gasket. I did that at just 11 PSI. ARP head studs and a GTE MLS head gasket solved that and I ran up to 20 PSI.

 

Will upload pics and update information once we dig into it.

He's got oil in Cylinders 2,3,5,6

 

2002 IS 300

Engine bay


Removed plugs, #6 was very very wet with oil after the 60 second drive into the shop


Compression test, with corresponding plugs


After plugs removal/compression test


Tear down further


part of the intake, all of the exhaust still attached to the head, so we used the cherry picker



Stripped and inspecting for damage


And finally the bad news we were hoping to avoid




Pricing options with him, will update more once we know more

 

Hmm not exactly round is it? That's pretty crazy.

 

Seems like a dealer repair like this on 13 year old car would not be cost
effective

 

Never seen that before - but I have never messed with the VVTi GE motors. They are much weaker.

 

While that is a true statement, of your opinion, I shall remind you that:

vehicle is located at a dealership however no one said anything about cost of such repair

 

this is the first 2JZ ive been into, and I had a bad feeling after the compression on Cyl6 came back with 0psi

 

What are the specs on the motor? What turbo? How many psi? Just curious. Never did much other then matainence on 2Js

 

I'd be curious as to PSI and what he was using for tuning as well. Stock 330 injectors? Stock head gasket?

My 2JZ-GE SC300 had 220,000 miles on it when I sold it a few months ago and I boosted and tuned it myself.

 

I will double check with him. I believe 60 mm and pushed 14 psi when it went. Was tuned for like 9 psi when he bought it.

Pulled the engine and trans out last night. I'll upload pics in a bit

 

12 psi dynoed at 385

 

Friday night he dropped the engine off, and trans off (to be built)

 

I had a free moment at work, and I cut apart his oil filter that we pulled off his car during tear down. Just to see what we might find in it.
