Hello everybody,i would like to ask about my cosworth engine,so today after 200kilometres,i saw little oil between exhaust manifold and head in the first cylinder,so does anyone know what's going on with this?thanks a lot

 

Most likely a leaky rocker cover gasket ?

If its on the corner it could be the cam seals or more likely the half moon ones... it gets blown down and onto that corner from many I've seen.

 

What headgasket you using? I ask because im sure the oil feed from block to head is at the front of the block, and ive had problems in the past with oil seepage at this point. Normaly with metal gaskets though where the block face aint been 100%.

 

it's not from rocker cover gasket,and half moons, in this places are clear,i using the standar head gasket,but the exhaust gasket in the first cylinder looks like the oil comes from inside,i mean the gasket is like "irrigating" with oil.

 

Sounds like Stu is nearer the mark then ;-(

 

the problem must be from inside head i think,the spark plug on first cylinder it has oil,and smoke oil from exhaust,the turbo is ok rebuilt with 360 thrust recent.i hope the problem is the head gasket as mine is standar....tomorrow i'l start the repair process ........

 

Its a Ford, it's allowed to leak oil. If it aint leaking oil, then it's ran out of oil to leak
