Has Anyone Used a Comp Cams Pushrod Length Checker??
 

Hey,

I'll be attempting to use my comp cams pushrod length checker this weekend to see what size pushrods I should be using. It didnt come with any instructions, and all I can tell is that it looks like you twist the top of it to adjust the height, but how does it stay at a certain height when it is loose like that, and does it have any built in measurement, or are you supposed to measure it yourself. What is the procedure for using this to check correct pushrod length??
Thanks,
Brandon

This is pretty much universal. It helped me.

Cool, thanks, that link helps a bit. Is anyone familiar with the CC pushrod length checker. and the marks that are on it?? Im wondering in they are there for height adjustments because it says adjustable in .050 incriments but i dont see how to do so.
Thanks,

Thanks :thumb: . Thats weird tho, because once you start to turn the fitting it seems it becomes too loose to use as a test pushrod, but I guess I'll figure it out, lol

Heres a crude method but works to an extent....i got it off Cmotorsports.com site, I think:

"A major problem in high RPM engines is incorrect valve train geometry. Make sure that you have the correct length pushrods installed. The easiest way to check is to take a magic marker and color the tip of one intake and one exhaust valve. Then, install your pushrods and crank the engine over a few times. Now uninstall the rocker arms and look at the tip of the valves that you colored. The marker will be worn away where the rocker arm was in contact with the valve. This line left should be in the center of the valve. If it is towards the exhaust side of the head, you need shorter pushrods, if it is towards the intake side of the head you need longer pushrods"
