My 300e is driving me crazy!
I really need help with this problem. I just replaced my 86 m1o3 engine (due to piston/valve contact) with an 88 m103. Everything went well until the engine ran for ten mins. and started knocking. I assumed it was a lifter caused from the engine sitting for some time before installation, but my neighbor who has rebuilt several enigines said it was a rod or main bearing. the bearings had a little wear and the rest of bottom end looked fine.
I replaced the bearings and installed the engine and still have the same knocking noise.
I guess my question is, how loud of noise does a bad lifter make? I thought lifter noise was more of a ticking sound. I am almost to the point of selling the car as is.
If anyone in the Poenix area knows any good mechanics please let me know. Closer to east valley the better.
