Ok so Im experiencing some ticking noise only at idle you can hear it. It all started after I blew my freeze plugs out when I launched my car at the drag strip with my 2 step. I got all that fixed and fire the car back up and its been ticking ever since. I since then have been around 500 miles in the car beat the hell out of it and still performs the same as before no power loss at all. Ive checked everything under the valve cover and everything was fine. Checked the oil and it was clean as could be. The only thing I can think of is its the timing belt tensioner. I did find that my cam gears were loose on the adjustment screws so we tightened them back up and it still ticks. Does anybody have anymore ideas on what this could be? Any help would be greatly appreciated

 

My engine was ticking untill I ran some Gunk fuel injector cleaner through it. The noise was there from idle up to about 4K rpm. After that engine noise drowned it out I guess. Give this a try, if it doesn't work you are out five bux.

 

Ok I'll try that thanks for the advice. I've already sent the injectors in and had them bench flowed and clean do you think this stuff will still help?

 

I've heard that one bad tank of E-85 can gunk up the injectors. Otherwise, if on gas, since you've done that, never mind. If on E-85 I'd suggest pulling and checking.

 

have you checked for exhaust leaks? they can sometimes make a ticking sound

 

what injectors are you running

 

some injectors tend to tick during normal operation.

 

The cam belt tension-er started to go out on my car at about 90,000 miles. It did not tick at all. The belt would just make alot of racket when engine was cold.

Is the ticking chronic at idle or does it go away at times?

 

Exhaust leak, check around the manifold.

 

Yes I went thru and checked all exhaust no leaks. I'm running id2000 injectors. Yea it's on e85 but the tick just started after I blew my freeze plugs and is constant never goes away

 

Anybody got anymore ideas?

 

^ was or still currently? I would get a screwdriver and try to pinpoint the epicenter

 

Ok I'll try the screwdriver method and see if I can get an exact aspect of where but I'm thinking it either the injectors or lifters just from listening to videos. I know I just had the injectors cleaned but I'm sure there was gunk in the fuel tank and lines too so they could be partially stopped up again so ima get some injector cleaner and run through it and see if that helps

 

My car always ticks, and it's piston slap.

What pistons are in your car? I run JE pistons, and because JEs are a full circle they will get noisier with age as the skirt deforms. The looser your clearances, the louder the noise will be.

 

I run .020 overbore wiseco 1400hd pistons. It doesnt sound like piston slap but if it is I guess oh well. Ima try to run some seafoam thru it tomarrow and see what happens. Thanks guys for all the help
