Valve keepers
Hello folks, I need some assistance. So I was informed my valve keepers looked a little funny when I was trying to fix another problem with the engine which lead me down the road of needing to check the keepers. Basically it looked like the intake valve keepers were sticking out further than the exhaust ones. Well I got some time to look into it:
So here is pictures of my #8 intake valve stem and keeper
Here is the exhaust side
Now it appears that the intake valve keeper is sticking out of the retainer:
I measured the gap between the intake valve keeper on this engine and it is .114” inch. The gap on what I believe is an untouched 906 head sitting on a 440 in the corner of the shop is .055. Is that an issue?
A guy that is helping me out mentioned he is concern with how high the keeper is sticking out of the retainer. On my engine the dimension from the top of the valve to the top of the retainer on the intake is .123, and .186 on the exhaust. where as the dimensions on the 440 in the corner are .140 on the intake and .172 on the exhaust. Is this normal? There’s nothing in the shop manual about this.
Now it is hard to do get this measurement with calipers because the top of my retainer has a peak on it. But this measurement is taken from the top of the retainer to the bottom part of the retainer as close as I can get it to the keeper. But on the intake side that measurement is .069, on the exhaust it is .024 (with the keeper being above the retainer). On the 440 the measurement is .040 from top of retainer to top of keeper on intake, and .017 on the exhaust (with the keeper below the surface of the retainer on this one). Is this an issue? Or is all of this just difference in design and I am good to go?
This is a picture of the 440 #1 cylinder that I used for comparison:
