Advice! #1 Spark Plug wet/oily!

Hopefully you engine building gurus can answer this for me :(

I pulled all my plugs today and found my #1 plug is wetter than the others.

They are all quite sooty, but look dry. #1 however, looks wet, possibly due to excess fuel, or possibly oily residue :(

Does this mean worn valve guides or piston rings? :(

If a compression test/leakdown shows this cylinder is on it's way out, am I looking at BIG $$$$ to do this one P&C?

Engine was rebuilt completely about 2 years ago :mad:

Advice appreciated.

James:

Its time to perform a leakdown test to see what you have going on.

The results will frame what your next step will be.
