oil pressure

problem could lay in the cylinder head. you say the bearings look good in the bottom end but did you plastigage them to find out what the clearance is?? remember, the cam has no bearings, if the cam bores in the head are worn, they can and will cause low oil pressure because of allowing bleed off rather then pressure to be built.

yes,i did plastigaged them & was good. what do you mean by cam bores? how & why does something like that happen?

simple, the area where the cam rides gets worn too big and allows oil pressure to bleed off rather then build up. it happens. they made heads that required oversized journaled cams too, but marked the end of the head with OSJ. did you make sure that the oil distribution block isnt threaded in the block too far?

It reads normal most of the time, when it started to tank like that I thought the motor was toast (I had just replaced the head). I'll try a new sensor next oil change, but I like the mechanical gauge for reassurance anyway.

I got tired of wiggy oil pressure reading's so I installed a real guage in place of the stocker. 10 psi is a tad low but within specs.

will over pressure trigger the CEL too? Cold running to work today (58*F) and my gauge was showing H right on the border of past high and I was noticing my CEL coming on, wasn't the knock sensor.... I don't think, I was in 4th with light throttle, no boost.

Sorry to thread-jack but as you guys were talking oil pressure...../

No, it will not, the computer does not monitor oil pressure at all.

nope oil distribution block is good also have upgraded oil feed lines
