I changed my oil.......some foam.

Postby steve allen » Wed Feb 01, 2012 11:57 am



I have 87 aspy that awhile back had issue with fan not coming on, never got in red before I could move air over radiator. But, this past Christmas shopping season, sitting in traffic, bike got in red, gurggled back through overflow. Tore down and found fan switch bad, fixed that and been driving without problems. Changed oil and filter this morning, found oil to have foam on top. Does this mean head gasket is blown? Is there something I can add to oil maybe to correct this? Or, should I drive for awhile and check and change oil again to see what is going on? I am really getting tired everytime I fix one problem, another one arises. Steve

Are you making lots of short trips? Foam is an indication of water mixing with the oil, the water can either come from the cooling system, or it can be due to condensation inside the engine. The condensation is usually due to lots of short trips where the engine cases never really get hot enough to prevent water condensing on the inside.. If you are making lots of short trips, then I would just suggest slightly sooner oil changes, if you are not making lots of short trips then I think you need to start looking at the cooling system and have it pressure tested to see if you have a leak..

I dont take many short trips, I did crank motor up and allowed it to warm up before I changed the oil this morning. I think I will drive a week or so and change and check oil again. I am thinking I will probably looking at replacing head gaskets. Normally, I will go for a good ride, an hour or so before changing oil, maybe, cause I only warmed up bike, this could be the problem. Whatever, I must do what I can do, alittle at a time. I have too much in my wing to set it aside. Thanks.

Is it a very hard job to do top end gaskets? Top end gasket set? I am trying to get pumped up if this is what I have to do to fix my problem. Steve

Doing the head gaskets is a fairly easy job. Especially if you have some mechanical skills. A clymers manual is a big help. While you have the heads off its a good idea to change the valve guide seals and the timing belts since youre already in there. I did my head gaskets in a weekend.

I agree with condensation from short trips. All the more reason to ride the wing longer. The wife always wonders why my 'short' trips to the store take so long. I alway answer with a big smile on my face.
