Oil pump sealer failure....again.....
Have very unpleasant problem with this sealer, and i really need expert opinion.
Engine is 2.0TS, lightweight FW, ceramic clutch, banancers belt removed(shafts was available, removal underway). Alfisti trackday here in BG, and before my last 2 runs i saw oil leakage from oil pump sealer. Engine was heavy loaded this day, but oil was in perfect temp range, water as well. And that's happen for second time, sealer was changed then, oil pump too. Same happen when engine in race condition afterwards.
Is it possible compression past through piston rings, and create high pressure in oil sump....or something like that????
However i drop the engine for entire revision, but i really must know what cause this.
