1986 Toyota Corolla 4 cyl Two Wheel Drive Manual 1xxxxx miles
i've been working on y car l8tly and i've just noticed a odd sound when I rev the engine to about 2k rpm. There seems to be a knocking noise coming from the engine, in fact, it's loudest at the exhaust manifold.
but, this only happens when the engine has reached operating temp and only at 2k-2500 rpm. After that it returns to normal.
I've had this happen to me before but it was on a carburated SOHC version of the current engine( 4AG-E) that is in there now. The SOHC engine ended up having a real bad knock which I do believe ended in a dead hole. But, in the SOHC engine the knocking was constant as for this one is just at 2-2500 RPM.
I pray that this isnt a pre-mature knock that will lead to a dead hole. Can u guys help me diagnose this further.
any help would be greatly appreciated.
have the same problem?
