Really Loud Ticking When Driving

[JET]

Do a leakdown test. Rebuilt engines can have something done incorrectly and take a dump pretty quickly. I am not saying that is the case, but definitely a possibility. Take the valve cover off and check all the springs to make sure one isn't broken or coming off (if one of the retainers was missed).

All the springs and everything in the head look fine. Just pulled the exhaust manifold and everything looks normal.

I am thinking a rod/main bearing.
Possibly piston related as well, start doing tests.

If one of the HLA’s has collapsed,
you really wouldn’t notice it visually, witch could be the problem.
But lower end engine noise like wrist pins could sound like a collapsed HLA. But I don’t know how the “Loud Ticking’’ noise really sounds like and at what RPM. a lot of things cause ticking like ignition timing off, low oil and so on.

And you could have outstanding cylinder compression and pass a leak down test and still have a bad bearing or wrist pin. I have driven some cars that for the most part ran like a champ with only 10 thousand miles deep, and pop something loose In the lower end.

I hope its not somthing to serious.

berda's 14b made a loud fast clicking noise throughout the rpms. We thought it for sure was lifter tick. Wrong, the turbo was the culprit, the turbine housing had a good size crack and had some shaft play. We put in a different turbo and the problem went away and he could drive his car without it sounding like a really pissed off chipmunk.

Yah my 14B has a crack in it and has a little shaft play. Right now im putting on my 20G so maybe it will go away.

my car was knocking at me too and it was a bent wrist pin which eventually let go and my car no longer runs :(

I am with nytrider, sounds like a bottom end fuck up. I had really bad "lifter tick" in my car too, the 3rd fucking day I have been able to drive it, she seemed to loose pull all the three hours I was driving it until I tried to race my buddy in a Civic hatch. She barely made it to 5000 and when it did it was fuckin knocking really damn loud. Does it ever stall after boost?

[munster000]

did the ticking go away after you put the new turbo in?

[blageo23]

havent driven it yet. Got to wait to get money to get it tuned.
