What are the causes and cures for excessive blowby?
I have a 283 with lots miles on it. It runs great. The only problem I
have with it is all the oil mist that comes out of the vent hose and
soaks the air cleaner. I have an oily mess dripping from my air cleaner.
New PCV valves have no affect. 20/50 blows out a little slower that 10/40.
I have been told, "It's the oil rings." The head has never been off of this
engine. There is no oil being burned. The plugs are clean. The compression
is correct.
Do I realy have to do a ring job?

I have an oily mess dripping from my air cleaner. > I don't have a solution, only more of the same... I noticed this when I replaced the breather in my 225. I couldn't find the proper breather, so I improvised. My car was a '70, and the earliest breather they had was for model years '72 and beyond. I don't think this was too much of a problem, though, unless crankcase pressures were higher back then. The car runs rough unless I open the air cleaner wing nut a bit. Unfortunately, this is NOT a fix as it eventually starts acting up again. > I have been told, "It's the oil rings." The head has never been off of this > engine. There is no oil being burned. The plugs are clean. The compression > is correct. I don't burn oil, either. I haven't checked the plugs or compression. The head was off the car once already to put in new valves. I don't think it's the rings. I'd be more inclined to believe that there's something clogging the system, and causing oil to evaporate at a higher rate. -- Jonathan D.
