1972 buick 350 cam bearings affecting left valvetrain?

[rook1957]

I bought a 1972 buick custom convertible last month, I have been going through some of the things that needed addressed. One being a rocker arm tick on the left side of the engine that was suppost to be rebuilt. I pulled the valve cover and found adjustable push rods and two rocker arms loose which I adjusted by lengthening the push rods. I was surprized by how little oil was oiling the rockers. I read somwhere the front cam bearing can cause oil starvation on the left bank of the engine. I have not pulled the right side yet to compare the two sides. Did this engine come with adjustable push rods or is this a bandaid somone used to cover their mistake?

bandaid approach. rocker tick could be lifters or worn out shaft or rocker. as far as oil goes, dont need much for the top, its the rest that needs oil.

I wish I could find that post, the guy said he pulled the front cam bearing and replaced it with one that he got from T/A products to fix the problem.

they're used mainly b/c with pedestal mounted rockers there is no adjustment, so when a motor is rebuilt and heads are shaved or the block is decked, the original pushrods are now too long and until it is all put together its tough to get an exact length. So, sometimes adjustables are used ...

There is a correct procedure for adjusting them and getting the lash right - if they are just snugged up they may be too tight or too loose.
