Could be due to nothing more than storage. Over time, coolant, oil, or fuel could've leaked into the combustion areas. Probably won't be a problem if driven regularly, unless a seal has actually failed during storage.

Good luck.

 

Thanks for posting up your results!

 

thank you so much for your help.... this has had me worried for a few weeks

 

looks like its time to take the plunge and try this stuff. I just cranked up a "new" low millage engine and its leaking like a seive. No coolant/water appears to be getting into the combustion chamber (there is no steam from the exhaust). However the block is "weeping" near the spark plugs and the primary injectors....

 

Very interesting thread...

 

Hmm, it might actually work in that case. Please let us know how it works out.

 

I have ran into similar problem, but with different cause. My engine's gasket is getting old and the engine is leaking oil, "flooding" the spark plug area, causing smoke and losing power. I had to replace the gasket and plugs then the smoke problem is gone and the fuel economy went back to normal.
