I checked valve clearance and they are ok, can it be a TCT?? What it will be if not TCT??

bye

 

Sounds like the infamous TCT...I'll see if I can find a link somewhere here where they have a vid of the usual sound.

Thats not TCT.

Sounds like a number 4 cylinder failure. look for high compression in cylinder 4.

 

Billman250@ what thing can do that?? Friend told me that it can be main/rod bearing problem :/

 

either way its bad.

was the car ever supercharged or turbo?

Could be oil jet bolt issue.

 

Hey billman,
I have that same noise. I pulled the engine and the head and cylinder 4 is very lightly scored. It barely catches my fingernail. Is it something that can usually be honed out? Then I can put in new rings and a piston or should I start searching for a used engine? I can takes pics of it. I am going to be taking it to it a machine shop but I would like a your professional opinion if its even worth wasting a machine shops time.

 

I have no turbo or SC, stock engine. If it's true I'am cry ;{

If I push the clutch that noise is gone - I had brand new clutch kit already installed right now and it's not help.

 

if you clutch in and it stops its a bearing in your trans... did you replace the bearings with that new clutch?

but idk how you would get such a bad sound off of the motor... whats your idle set at? i know mine was idling around 600 rpms when i got it and it sounded like sh*t with the ticking etc... got a valve adjust and bumped my idle up and it sounds fine... also a new tct... sometimes on startup i get a little ticking still tho

 

clutch release bearing was replaced with a new one

 

The stock cylinders can be bored. The machine shop needs to be familiar woth FRM boring and hone procedures.

Yes post a pic. sounds like your scoring is a non issue.
