Has anyone used synthetic oil in a P-60? A friend who uses synthetics in all his engines suggested that a synthetic oil might help with my chronically sticking exhaust valves in my P-60 (another story in itself!) |

David, I suggest using a quart of Shaler's Rislone instead of a quart of oil in your crankcase.
Many older mechanics use it for sticky valves and it works wonders.

Howard,
Thanks for the tip. Do you replace all the oil with Rislone, or just one quart? Also, where does one find Shaler's Rislone? |

Shaler's Rislone is an ultra refined oil and does wonders for engine preventative maintenance;
especially good for sticky valves and lifters,
One quart is enough for most engines. It is available in most parts stores like AutoZone, Advanced Auto, Pep Boys, etc.
I have been using it in my cars and boat for years and it really works.

It would be worth a try to run Marvel Mystery Oil in the fuel. I used it running my P-60 as a preventative measure to help deal with the corrosive effects of a marine enviorment on the fuel system and the top end of the engine. |

My guess is water getting into the upper chamber either through soot buildup at the junction of the exhaust line with the exhaust pipe or hopefully not so a small leak in the exhaust manifold. When was the last time you examined the junction with the exhaust pipe and the exhaust manifold. Carbon/soot build up in the area of
that junction is a a classic problem Any evdence of water on the spark plugs??? |

Howard, Thanks for the follow-up. Eddie, I've added MMO to my fuel, but haven't run the engine enough so far to tell if it will help. Valves are still sticking, at any rate.
Richard, I've got the exhaust pipe off now, and the manifold/pipe junction is mildly sooted but no obstructive buildup. When I pull the spark plugs, I often see small beads of liquid on the valve heads and environs that look and feel like water. Doesn't feel or smell of anti-freeze (fresh water cooled engine). No water or rust on the plugs per se.
My next step is to pull the manifold and check it out directly, unless you folks have another idea. |
