Went to put new spark plugs in my project 172 and found water on the plugs for the two central cylinders, I did a degrease of the engine at the weekend using loads of water (as it also had loads of oil down the cam belt side of the engine), but when pulling off the leads they were dry and clean, the plugs had water on the part inside engine, but didn't seems to have any rust! But after restarting the car water did slowly drip out of the exhaust.
The reason for the new NGK plugs the car was misfiring when I got it, and with a broken off back box it was hard to tell how bad. Thought I might be able to get plugs and possible leads to sort the misfire.
These plugs were fitted they looked black with water on but no rust. Would these be correct for a 172?
My questions are:
Do head gaskets or heads often go on these cars? I looked in the forums and can't really see any one with this problem.
Does anyone have a guide to removing the head?
What would be the most likely place to look for an oil leak cam belt side?
Thanks for any help.
