i read on another post that says "If the connecting rod (or anything else was bent) then the engine either would not run, or would vibrate so badly you'd know something was wrong",made by DBCherry.
I have been driven crazy about some engine viberation,it really viberates at certain rpm's and just above a high idle.This last weekend i spent aboout half a day workiing on it,looking for something that was loose,the only thing i could find was a screw kinda loose from the engine mount to the firewall,it seemed to be better but the vib is still there,i'm not afraid to take the engine apart to check out a bent rod or anything else BUT should i take it somewhere that works on these ?,or a competent LHS ?.Engine is .61 Evolution.
Thanks
