I took the T for a drive Saturday and made a couple 1/8 mile hits then it sounded like it spun a rod bearing.
The oil pressure looked good and the sound was coming from under the left valve cover (the easy one to remove), so after the engine cooled down I took it off to find that #5 exhaust adjuster came loose so much that I could almost lift out the push rod.
After feeling the rest of the push rods (most turn), I guess many of the other lifters do not have enough preload on them.
Can't believe it ran as good as it did. Not a miss with the #5 exhaust valve just barely opening like it was.
Couple questions:
1. Even though I have adjustable rockers (T&D roller) and the threads looks good on the rockers as on the TA performance site should I get shorter pushrods since the block and heads were cut on ?
2. I have read of doing doing the adjusting two different ways (as was also with the 455 that I am more aware of) and wondered what method is best with the turbo engine ?
