1968 MG Midget low compression/ excessive exhaust smoke whi

1968 MG Midget

So I just replaced the head gasket, and now when I start the car I see small amount of white smoke when I rev the engine I see excessive white smoke. I can also see little splats of oil coming from the tail pipe. Also the compression is low in cylinder number 1 and fine in the other ones (2 3 4). Any ideas of what the problem is or where to start looking?


any help is greatly appreciated
