I have a possibly dumb question...
My 1994SC has been experiencing what I consider to be "rod knock" for quite some time now. It has not gotten any louder and is not apparent at cold start, at idle or even when revving. Under load and in drive, however, this knock, which reminds me of when I actually HAD rod knock in a previous engine, comes shining through...
Now, my buddy claims that the sounds of detonation sound eerily similar to rod knock, but never experiencing this first hand, I have no clue. There is no oil pressure drop at high-rpm and, in his theory's defense, this only really started after the MPII system (with 85mm TB) had been installed. I have 42lb Bosch Ford Racing injectors and a 255lph forced induction fuel pump (WalBro). The EEC tuner, to the best of my limited knowledge, is setup fine for this application and these are the only engine mods.
Just curious if anyone could add to his theory or tell me how to confirm mine. I am contemplating replacing the engine and ressurecting the 94 with a warrantied Ford reman'd and keeping all these bolt ons.
Any thoughts???
