I HAVE A 2000 DODGE NEON SOHC WITH A MAGNUM PORTED HEAD WITH A CRANE CAM (NITROUS PROFILE). EVER SINCE I PUT THIS HEAD ON MY CAR I HAVE A LOUD VALVE TYPE NOISE WHEN REVING ENGINE. ALMOST SOUNDS LIKE VALVES ARE FLOATING.

PLEASE ADVISE ?? ANYBODY GIVE SOME SUGGESTIONS

THANKS

 

Throwing any codes?

It could either be bad rockers or a floated lifter. And since it's pretty loud at idle and RPMs I'd say it's probably floated but it could also be bad timing as well. It's tough to say which is why I asked if it was throwing any codes.

 

timing is good, and there are no codes. what should i check ?

 

I would check the lifters and the rockers, its not a good thing either way, I wouldn't drive any more than you absolutlly need to till its fixed.

 

i have had this noise for 3 months now. i pulled off valve cover to see if anything was broken. all good !!! it drives and runs strong but the ticking noise is annoying !!! is it possible that magnum head i installed with crane cam #12 dont work together ??

 

No, that isn't possible.

I'm almost guessing it's your rockers. I'd have them replaced.

 

im telling you it has been there for 3 months and still running hard everyday

 

is it possible that one or more valves were installed wrong ? intake+exhaust backwards ??? is it possible ?

 

Not likely, they can only go in one way in my experience.

I'm telling you it's a lifter or your rockers. It'll still run good and strong but be wary, when it finally breaks, it's going to do a lot of damage. I'd have it repaired.

 

A lot of neon have a tick when they are cold and you can hear it slightly when they are warm. Its just the motor.
