A mechanic stopped by my house and gave it a look over and thought it wasn't leaking because there was no apparent oil on the sides of the engine. I don't think it leaks because there is never any oil spots on the ground where I park. Occasionally there is smoke while I'm driving....I notice it most when I accelerate after I come out of large curves in the road. On start up, there may be a little, but not much.
When the mechanic friend stopped by my house and looked at my car, he tested crudely for the compression.....he took the oil cap off the engine, held a small piece of paper over the opening, and had me start the engine. Air strongly blew the piece of paper up as he held it over the hole with his hand. He said this was a sign the compression was not good. Although he just did a free, quick and dirty inspection of my engine, he said either replace the engine or add some engine restoration additive to the oil. I added the restoration additive to the oil, and when I tried the piece of paper compression trick, it sucked the paper in...it did not blow it up as it did before. However, after a week or so air was blowing the paper up again. Does that give a good idea of the state of the compression, or is that too crude of a method to truly determine?
Ok, I will get a compression test done this week and get back to you on the numbers. Thanks!
Yep, I had a compression test done yesterday at the toyota dealer in town here, and the numbers the lbs. they gave were 200, 80, 175, and 60. I suppose those are for each piston? Is the engine in dire straits?
