This doesn't look good...outboard spooge

[ShoestringMariner]

I was running my old Johnson TN-28 trying to sort out the bugs when this white-grey foam started oozing out of the stem under the powerhead. I just put coils and an impeller in this motor and I hope it wasn't a waste. I took it apart to investigate and it appears to be coming from the crank seal?

I assume it is fuel/oil and water mixing together somehow? I'm concerned it is a cracked block

Help??

Plugs are new and clean. None of this ooze in the exhaust chamber.

Motor is not running right. Was lean sneezing a lot and struggled to rev high if this helps

I share your concern with a cracked block or a bad head gasket, Start with a compression test and let us know how it goes, ive seen that goo before when I blew a piston ring but it came out of the exhaust.

Good news, I found out from the helpful folks at the AOMCI forum that these old motors do this to lubricate the pivot stem...fortunately removing the powerhead is an easier way to change the impeller, so not a total waste of time (as far as re-assembly)

thanks for your suggestion
