Ok might be crazy but i think my truck has a ticking noise at idle no codes.truck has 90,000 and i don't know if it has had valve adjust. It run like a raped ape!!

 

Diesels tick, click, rattle, bang, knock, shake, and more if you get a fixation on some noise. Mine has a idle knock that unnerves me, but when a injector went down I knew something was really wrong. Your buddies are the worst, cause theirs don't make that terrible noise. Theirs make some other noise.

 

Could be a crack forming somewhere along your exhaust manifold, or a an exhaust manifold gasket is starting to go...causing an exhaust tick. Is the tick there all the time at idle, or more so when the engine is cold/warm?

 

It is there when it is warm or cold more so when warm i don't think it is in the exhaust how often do u need to adjust the valves

 

i just adjusted mine yesterday, it sounds a lot quieter. this adjustment is the second one in 200,000 miles

 

exhaust manifolds on these trucks are known to crack, a lot of times the crack will form under the turbo where it's hard to see

I will check that out so if it is cracked is it better to replace with a oem or a aftermarket one?

 

Depending on how much you want to spend, I would go for an after market 3 piece one. I just finished R&Ring my stock manifold with an HTT one since my stock one was basically cracked in half!

However usually when it is the manifold it will quiet down once the engine is warm due to the casting expanding and closing off of the crack. But I would still check your manifold and gaskets just to be sure.

 

thanks is there and hp increase with the 3 piece.i'm going to check it out and see if i can find anything out of the norm. also i am wondering if i have the 53block can't find and thing on the motor is it marked some where easy to see
or do i need to look around?
