P.A.
For the past several years my 97 700 sx has been a bear to start after sitting for several days. Thinking that it was a stator issue. Or wire harness. I had the pipes off. After pulling my arm off to look for spark. I noticed oil dripping from two of the exhaust ports. keep in mind pipes are off. I inspected the oil and it had a small sign of green tint to it. Not allot. I believe it to be coolant. My klotz is red. Any way. Pulled head,gaskets and head apper to be fine.

Is it possible my hard start problem is coolant is leaking into the crankcase. Killing the plugs. And where would the coolant leakcome from. no external leaks to be seen . Did not do a compression test. But seems to be strong by pulling.
 
IF the head gasket looks good then I would pull the jugs off and look at the gasket there. It would be easy to have a leak going into the crankcase with out any outer showing.
From what you explain, I would agree that a coolent leak is your starting issue. After sittings some coolent leaks in to the crankcase and then the mixture is junk and you have to pull and pull until you get a cleaner mix in the crankcase. Once it is started the coolent just steams out the exhaust.
 
If the coolant is leaking into the case, then the coolant is being pulled into the cylinders thru the intake port.
 
Ok, I will agree w/ the intake port. Thinking cracking of both cyls. or just gaskets. Whats the chances of both cyl. issues @ the same time. Or how is this all related?
 
I would say it's just gaskets - bottom end is only separated by the bearing which doesn't seal side to side. If you take the cylinders off, it will be very apparent where the leak is.
