Old friend seeking help again

[slacker69]

Been a long time since i have been on these boards but i am a veteran. I have a Tick i cant find and would like some ideas before taking it somewhere or me tearing down the motor.


It is a pretty load tick that u hear in park and increases in speed with rpm. I have done almost all i can think of i replaced the lifter redid the rocker arms and replaced plug wires and checked coils and eunpluged each injector one @ a time while running to see if it was them no change in sound I even went as far to replace entire exshuast system to all stock from the motor back from RKsport headers, to stock tubular manifolds and so on. But yet no luck i would like any help please before i waste money or time.

tranny?

Where does it sound like the tick is coming from?

Lift the car up, start it and get underneath the engine.. where does it sound like it is coming from?

How loud is it?

WHen you replaced the lifters and rockers did you check pushrod straightness?

What cam do you have?

Does it sound like its 1 tick per revolution or several ticks.

[slacker69]

cant pinpoint the tick but it seems to be louder on the driverside. Stock cam and the motor is a rebuilt with only about 6000-7000 miles on it all the pushrods were stright they are chromemoly pushrods i had left from first cam swap.

exuast leak at the headers ?

[slacker69]

Cant be that i had headers and full custom exshuast and replaced with stock headers with all new gaskets and everything and noise didnt change one bit

something hitting a pulley, or the belt? check all the open things that spin faster with engine RPM

also, are you low on coolant by any chance?

[Magnus]

The answers you seek in the valvetrain you will find.... yes....

[Fredless]

Mild piston slap?

[LordoftheBling]

Thats something to check... Its unlikely but free or cheap. Take the pulleys off mae sure they are clean, and put them on tightly even with a little grease. I have tracked a tick down like that before. And woudl chec ther before I pulle the valve covers again.

in fact just to rue out all the accesories just take off the belt and listen for the sound if it still happens while none of the accesories are spinning then you know what. good luck

Ran it with no belt tick still there so if i have time this weekend i will pull valve cover and run it without cover to see if i see anything out of place

May as well start moding again while you have the covers off ;)

Hope its nothing major, but you've seen all that before I guess!
