blown head gasket yet no water on spark plug? 1992 Evinrude 90 VRO

[scmutiger]

I am wondering if this is possible? Also, could a leaking head gasket only affect the compression on one cylinder?


115 lbs on 3 of 4 cyclinders -- went from 80 to 85 lbs on the bad cylinder after a decarb on muffs.


waiting on gasket and manual to be delivered before I pull the head....might do another decarb in the meantime.


Thanks,

head gasket does not always blow into water passage. yes it can effect only one cylinder.

Remove the cylinder head now so that you can relate to us what you find. You'll need to remove it anyhow.

As the above 2 posts. Gasket can blow anywhere, not necessarily just the waterways. It will still lose compression and yes it can only affect the 1 cylinder. It will only get worse the more you try and use it.
Lets get the head off and see what is going on.
