1982 v150: white exhaust smoke

[fishingdan]

The last time I had this engine running on muffs, I noticed that the exhaust was more "whiteish" than I previously noted (much more actually).

Compression checks out ok on the engine (117 to 120 on all six). I am guessing that this is a gasket issue or, worse, a corrosion issue that is allowing water to get into the exhaust circuit. Like I said, that is only a guess.

There has been no difference in the tell-tale flow to speak of. That said, this engine has never really had a good tell-tale flow given the design. No overheating issues.

Any suggestions on where to start looking for the cause of this?

Thanks,
Dan

white smoke means water. check if one of your plugs looks like it has been steam cleaned. there you will have water intrusion from the cooling system. it is not the exhaust, as the exhaust and water mix anyway, in the leg.

I had the same thing last Spring. # 6 plug was nice and clean. This time I was lucky and it was fixed with a new head gasket but I doubt that I?ll get way that easy next time. I have lots of erosion in the cooling passages surrounding the heads.
