A while ago I did a 4th gear pull on the highway. After the pull I noticed a ticking in my head area. My oil level was kind of low the following morning when I checked after noticing the ticking. I have pro 1 cams, pro springs, retainers, and valves. Fresh head build. Car is tuned with Neptune eprom. Recently ajusted valves to .006 in and .007 ex and the ticking is still there. It sounds like it's just in either the 1 or 2 cylinder but i could be wrong.It doesn't get any quieter after the car gets warmer. Not sure what a piston and valve hitting sounds like, but it does sound like something may be touching. If that makes sense. Cams I beleive were set to 0 before the tune. Camn anyone offer any helpful suggestions to what the prob may be. thanks

 

bumping for help

 

Most likely u have a minor melted piston from the side walls of the piston

 

If you did a valve adjustment after it happened and it didn't help, it's time to take the head off and check it.

 

A minor melted piston? I highly doubt that's his issue. Take a video clip and we'll be able to better assist you..

 

check compression, if you have a bent valve this would yeild lower compression

 

Before I take the head off, I'll do a compression test. Thanks for the suggestion guys.

 

Probably a stuck push rod.

 

Do a leak down test instead

 

If I had to guess.... I'd say bent valve, but that's just a guess.

 

doesnt high stiffness valvetrain click normally?

ive never heard a quiet motor with high end valvetrain.

 

rod bearing if the oil was low

 

thanks for the uggestions. I'll check them in order of easiness. Someone also mentioned to check valve lash, so I'll check all those out until I find the problem. I forgot to mention that I have the Bosch 1000's. Someone said they could tick pretty loud.

 

check your LMA, could be sticking.

 

I have the new spring b series lma with the washer. I was thinking that too at first.

 

I would assume it would be a bent valve, specially since it happen after a pull. I'd adjust the valve lash, and see if that fixes it, if not do a leak down and go from there.

 

MY FRIENDS B SERIES WITH PRO 1 AND MATCHING SPRINGS SOUNDED LIKE A DIESEL FROM THE VALVE TRAIN, FOUND OUT TWO INNER SPRINGS BROKE. HE GOT LUCKY NOTHING DROPPED
