The exhaust manifold on #4 cylinder. The Tractor is new to me and I don't really know its history. It seemed to run fine before other than some dirty carb issues from it sitting. Any ideas on what would cause this? Collapsed ring? Stuck valve? or just blow by?

Thanks in advance
 
Maybe #4 cylinder lost oil control on the rigs. What"s the #4 spark plug look like? If it"s black and oily then that"s the problem. Sometimes a few ounces of ATF over night in the cylinder for a few days can help the problem. if not, Run a dry and wet compression check and if #4 is low you might wat to re-ring it. And while you"re there, you may as well do the other cylinders. if you oil pressure is low (<15psi at 400 rpm lo idle at operating temperature0 you may wat to check the mains and replace them and rebuild the oil pump. The other option is to live with it.
 
First I would say, bad intake and exhaust manifold to head gasket. Cause of oil leaking, I would guess bad valve seal or worn oil ring in cylinder.
 
If you need to use it now then buy a plug extender so as not to foul the #4. It keeps the electrode away.
 
I picked up some GM upper engine cleaner and put 3oz
in the #4 cylinder. I left the cleaner in there for
about an hour then added a non-foul adapter and new
plug. Started it up and she runs great now. It was
unreal how much smoke it created at first. That
cleaner is some amazing stuff you could eat out of
that cylinder now. I drove it around last night for
about a half hour and seems to be running great.
Thanks for all the replies. By the way the GM part
number for the cleaner is #88861802
