I was mowing at 3/4 throttle when all the sudden it let out a puff of smoke, I left it running, stopped and opened the hood just in time to see oil come flowing out of the top of both cylinder heads above the spark plugs. I shut it down before it ran out of oil and hauled it back into the shop, where it has sat since September. I'm wondering if both gaskets popped, it appears the oil came from out between the cylinder head & the block. I need to get it going before mowing season starts again. Thanks in advance

The heads are attached to the
CYLINDERS with a head gasket between, the
Cylinders are attached
to the
Block with RTV/silicone type sealant on the M-18.
They usually don't leak OIL from those areas, but as Matt said they do blow front/rear seals and it gets blown by the cooling fan into those areas so a little disassembly/detective work is in order to see where it is originating.
