My compression right now is 80 80 80 80 100 100

:(

If your compression is that low, why are you worring about oil and such?

It's time to tear that engine apart and rebuild it. Any compression below about 140 lbs/sq indicates worn piston rings. Compression is typically between 180 (factory spec) and 150.


I was reading the info on a can of Liquid Wrench™ and it suggests that you put in some before you change the oil. It's supposed to thin the oil a little, and helps more of the crud get out of the engine. It sounds like a few treatments of that would really clean out the engine.

thx

This is the most idiotic thing that I have read on this web sight . Shure just pore some gasoline in the engine, we all know how gas will clean grease off our hands . Then light a match over the valve cover inlet and watch the fire works ! For crying out load , if you have an old tired engine that is showing such low compression , leave it alone untill you can do a rebuild . Just change the oil and don't abuse it . Other wise you will be walking insted of riding.

His response may have been a bit tounge-in-cheek (don't correct people's spelling, we all know what he means), but the point Gary makes is valid. Leave it alone. A high mileage, low compression, and in other words tired engine does not need the sludge cleaned out of it. It will only lead to further problems. The engine needs to be rebuilt or replaced which is what the author of this thread is contemplating anyway. He's just looking for a way to keep it going for a while.

NOT!!!! :stupid:

You may want to skip the oil and filter change altogether. Just keep oil in the ole gal. I wouldn't put high detergent oil in an old sludged up motor. Try to find some non detergent. It'll keep everything slippery and that's all you want until you build a new engine.
