I don't really believe in using Mechanic in a Bottle (You know, those miracle fix anything gimmics for head gaskets, oil seals, etc) but I was wondering if anyone had tried one on a Wankel Engine and had descent results. My car smokes like hell at high RPM and under load. The only way to fix it would be a rebuild but the motor runs fine otherwise.

 

If your car is a TII the turbo bearings and seals can also cause smoking, even if the engine itself is in spec internally.

 

do not use any sort of mechanic in a bottle if your oil control rings are gone, anything thing you add is just gonna gunk up the rest of the motor when you need to rebuild
