Ill start with the simple bit. Does the main earth strap from the battery bolt onto the side of the gearbox?
I posted some pics of my cosworth and everyone said the oil breather was plumbed up wrong. there is 4 pipes from it and i think its bailey. The top pipe with nothing on it is solid, Does this have to be drilled out? The other top pipe goes to the block on the inlet side. The big pipe at the bottom has nothing on it and its oily if you stick your finger up it but the engine bay is not oily if it drips it must be going down past the side of the engine. The other small pipe at the bottom goes to the inlet side of the engine as well. I cant see where it ends but i can feel and its somewhere below the oilfilter housing. There is other threads on oil breathers but i dont understand what kidney boxes and stuff is. I think i read in one that a pipe goes to the exhaust side somewhere under the turbo but the only hole i see is the oil return from the turbo and theirs no other pipes connected to it.
