If you see water in your oil, your in for trouble. I know a guy in the UK that makes copper head gaskets for the M103. You may want to consider that route next time around. Maybe even O-ring the combustion chambers and oil/water ports. You also should think about upgrading your water pump and radiator as well. A third of the energy you produce is heat and you've effectively tripled the output. I forget, are you running 8:1 or 8.5:1 compression?
Good Luck!

I was running 9 compression but my other engine with cp pistons I have 8,0 compression and O-rings on the block og each cyl.

But this engine I was running now I only had stock gasket and I think it should handle 2 bar without problem if I stoped racing with motorcycle hehe. I was running at 9000rpm without water in the engine after the hose came loose and it just exploded water everywhere hehe.

About waterpump and radiator is no problem eather, I checked temperature all the time and it was allways stabil at between 87-92 at warm summer day at 2bar boost

The think is I could save this engine if I changed the gasket but I had no energi or time to do it and I just keeped on driving with broken gasket and just waiting for engine kill. I have some new plans and thats why i did not care about this engine this time

By the way I have copper gasket and several layer gasket to both m103 and m104 and m103 3,6 but I think that stock gasket works as well.
Cyl stainless O-rings and stock gasket I will use with my other race egine m103 with cp pistons and pauter rods.

Most impotent for me now that I know now that I can handle 700Hp with stock engine so now I can do someother things in my new projects

M103 POWER!

I just must finish the album and then I can fix the car
