OK My friends.. Good news but a still a little trouble that I need help with...
Block was sleeved, engine re-assembled with extra care, no screw penetration (confirmed), re-paint, accessories, back in the engine bay, fluids in, no leaks.. and brake-in started...
Everything was OK the first seconds until we noticed an important oil leak through the oil filter base and we had to shut the engine off, removed the filter and bolt was tightened, filter back in, started the engine again but the leak continued, this time in much less proportion.
We did not remove the filter base in the sleeving process and while discussing what can be happening we remembered that for an unexplainable reason we used both the thin and the thick filter-base to block gaskets that came with the kit...
Here comes the question .. Which are the correct gaskets to use on the filter-base and also on the attaching bolt?
Thanks again advance for your immense support
