If the head gasket was leaking, water would be beaded up on the end of the plug when you remove it. Had a bad crank seal been ruled out yet? Exhaust pipe on the bad side stopped up? Good luck and keep us posted.

 

edit: Oh yeah...........I didn't notice if you had swapped plug wires left to right. That would completely rule out it being an electrical issue if the problem persists on the right side.

ok, i replaced all electrical. every thing. used a different carb. i even pulled the gear next to the clutck on the crank and replaced it. i figured maby it was wore and oil is leaking into the crank. i even mixed 70 to 1 to see if it would smoke a lot and it did. when i replaced the crank new seals were installed. radiator level is good, tranny oil looks good. the heads not leaking. this is like a bad dream. i`m going to split the case and take it to a shop where they spray it and put it under a blacklight to look for cracks. i dont remember what this is called but its cheaper to do that and get it welded then buy new cases if thats the problem. from there i`m going to install new gaskets and seals, and shave the head. if anyone has a last idea before i brake it down let me know. i`ll start stripping it in the next 15 hours or so. thanks for the posts. This is my 87 Banshee. yea i know the flowers just dont cut it but its not about the dam flowers lol.

Well I would sure do a leak down test on that motor before I opened it all the way. No leak= a waste of teardown time. You may find a leak but unless you have smacked the cases, I have never seen one stress crack. The magnafluxing shouls be a last resort. There plenty of other ways of finding the problem. Once you identify leaking, you need to find the actual leak. That is crucial so you know you have beat the problem with a proverbial sledge hammer.

magnafluxing is what its called (thanks). What exactly should i do for that leakdown test? the cases look fine but i dont know. it blows smoke and its very lean. all i can think it could be is the case being cracked.
