You just have to work the cooling air intake bellows off the intake flange and remove a handful of 6mm bolts (10mm heads.) Note that 1 of the bolts is "inside." There should be a black rubber gasket/seal/cuff between the generator and the pulley housing. I have spares of these if yours is missing. > I have to get a 15mm socket before I can check the tightness of > the lower head nuts, but would those being loose cause an air leak, cause > Muir says it would sound like Thor was hammering around in there, which > it doesn't.

Slightly loose will just make leaking sounds; very loose will start hammering. Neither is a good thing. Some 72-3 cars got 2 hoses from the air cleaner, one to each head. These fit onto the air cleaner at 3 O'clock and entered the heads vertically downward near the #2 & 3 spark plugs. Unless you have one of these engines you won't have these hoses. Right now I can't think of anything else this could be. > Could I > have a crack in the cylinder? How would I find out? Very unlikely. There is always some leakage past the rings which is normal an quite noticable when hand turning the engine. These actually seal better when the engine is running. > In a different diagram it calls what I thought to be the > crankcase breather the oil breather...is this just a different name or > something completely different?
