This on going problem started after I rebuilt my 1.8 engine last year. Since then I haven't driven the car and I've put it on the back burner and finally ready to face it again.
Rebuilt the 1.8 with all new bearings and new rings. There is a definite engine knock at idle and throughout the rpm range. This is not a ticking noise like a valve out of adjustment but a bottom end knock. I did check valve adjustment and everything I could think of. When I pull the #3 spark plug wire the knock almost completely goes away but not completely but definetly better A couple members said it was probably a rod knock so with the engine in the car I pulled the head and #3 piston and cylinder and tried another rod but the knock is still there. So I guess take the engine apart and look for a mistake I made on the bottom end rebuild right? Anything else I can try? Thanks in advance. L |
