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 |

you can pull and strip a motor in one day.
Then take the crank, rods and case to a machine shop for inspection. You will need to order a new gasket kit... you will need to order new rod and main bearings. I would hold off on any bearing order until you hear back from the machine shop. Could be two long weekends, fixed. Might be a few weeks in between for machine work to be completed... Don't avoid it, just get it done and you will be happier in the long run. It will also be alot cheaper to do it while you have not wrecked anything. |
