there is a slight ticking noise coming from my top end. It sounds like a lifter noise that seems to be coming from the exhaust cam shaft.... Has anyone else had this problem????

 

that sounds like a rod bearing. what happen to make it tick?

 

rod bearing... lol what?!?!

could definitely be lifter tap, does anyone know if the valvetrain uses hydraulic lifters, solid, or rollers?

 

My understanding was that they were hydrolic lifters....

 

There hydraulic lifters, so I believe that it is a lifter noise. it went away for an hour, then came back.. It's intermittent. I guess Ill just keep checkin it, thanx for the responses.

 

could even be the fuel injectors...

 

My car does that sometimes too on startup, but it goes away within a couple minutes. Should we take it to the dealer?

 

hmm well to my knowledge hydraulic lifters are non adjustable, they simply pressurize with oil and adjust themselves to the correct height, might be an oil pressure problem, low oil, oil is having a hard time getting to the very top of the head

 

Whats even better is we don't have lifters We have cam followers

I lay my money on your timing chain tensioner is busted. Seen it before.

 

I got a whole timing kit done at a dealer under the table cause it was knocking it was good for like 3 weeks and now it's ticking and it sounds towards the middle of block now I already have a new tensioner coming in the mail from zzp but just in case would it be my lifters or anything else besides the timing tensioner??? Please help?

 

when my car had a ticking noise back in the day before I had to replace the motor, it started a week after I used non gm 4718 oil (royal purple) the ticking sped up with rpm. couldn't figure it out till gm had torn my motor apart. what we found was the last cam lobe on intake cam right by the cam gear was worn away to almost nothing leaving 2 thin slivers of metal on either side and worn away between them. so it was still opening the valve. it sent that metal through the motor and scored oil pump gears and cylinder 4 wall. so if that's what ur hearing, take off valve cover and check to see if all ur lobes are still there. and hope u didn't use oil u shouldn't have.
