I have a 509c.i engine with a 2.3 whipple and hydraulic roller cam. I have about 30-35 hours on my new engine in 2 seasons and she runs great. My question is do I need to check my valves or wait longer? I'm not sure how long they recommend between valve checks. Thanks casey

There is no reason to check them with 30 hours unless you are hearing some noise or suspect something is wrong. Other than that, let em be.

if you mean valve adjusting,you never need to readjust with a hyd cam.

It depemds on how hard you run it. Usually on blower engines 50 hours is a good number to do a compression check. If your talking about valve lash you shouldnt need to do that.

Yes I was talking about checking valve lash. So I never have to check them? Thanks for the responses especially young performance. I think you answered every question I've ever had lol.

That is correct, the lash doesn't need to be set. Glad I have been able to help. Keep the questions coming and i'll do my best.lol
