how often do you do valve adjustments?

[u3b3rg33k]

The cam between the cam and the rocker is the same... thats why you can wiggle a rocker back and forth against the cam and the valve.. then when the lobe rotates around it takes up the slack and opens the valve.

I don't think you said what you meant to say, and I don't want to put words in your mouth.

Every 2-3 oil changes so about 8-12k miles it doesn't cost anything to do a valve adjustment so I don't see why you wouldn't do it fairly often

Just edited it. Thanks for catching my mistake :)

OK, now I can argue with you ;)

the space doesn't have to be the same if one side is longer than the other - they'll be proportional, but not equal.

So you could still have the play, but if you did the adjustment with the feeler gauge in the "wrong" place, you'd be setting the wrong clearance.

did that make sense?

Before I could write out my disagreement with this, I decided it was probably correct.

Adjust to .010 then put a .005 on the cam side and measure the gap on the valve side..then let us know :D

[u3b3rg33k]

Well I'm not saying its 2:1, but I don't think it's 1:1. I thought I read somewhere once that cam side adjustments were somewhere around .009" but I can't seem to find it for reference.

[5Toes]

I dont see how they would be different, but okay..?

[u3b3rg33k]

X1 > X2


like so:


if one side is longer, moving short side x amount moves long side y amount.

You guys have way too much time!

[5Toes]

Well if somebody figures out the ratio, that would be sick.

I find it much easier to get an accurate adjustment when using the feeler against the cam. Plus it doesnt bend the shit out of your feeler gauge!

[dnguyen1963]

Angled feeler gauge is cheap, 5toes.

Funny story, I once did a valve adjustment with a can of herring:

I'd suggest you adjust them cold, with a herring can lid.

Very simple to do:
1: Misplace your feeler gauges
2: get angry
3: find micrometer
4: measure stuff until you find a .010" object
5: cut the herring can tab into a rectangle
6: adjust valves

for those interested:

[dnguyen1963]

No shit, but seriously angled feeler gauge is less than $5 at HF. But, I guess you can eat Herring Fillets and adjust the valves afterward. It's a toss-up.

Bavauto sells a whistle that you can plug into the sparkplug hole to find TDC (it stops whistling the the piston is all the way to the top). It makes adjusting the valves easy.

my screw driver does the same thing.

Angled feeler gauges help, but still ti is hard to get it in the right spot and get the "pull" consistent.. for me anyways
