How that works is you put air pressure to the cylinder with the piston at TDC. With the air pressure at the cylinder, you listen for air at the carb= intake valve leakage
the exhaust=exhaust valve leakage
the oil fill on the engine= rings leaking
look in the radiator =cooling system leak

I do not have the actual tool which tells a person what the actual percentag of leakage, I use a sparkplug which I removed the center part of the plug and braized in an air fitting. I can use the adapter to feed air pressure to the cylinder and listen for leakage.
Be careful as sometimes the air pressure can cause the engine to turn. Watch out for any parts of the engine that you would normally be aware of withthe engine running,,(Fan, alternator, power steering and those type of things)
There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!

It may not have the power it should but it won't smoke. I would pull the plugs from the smoking side and compare them to the other side. You will most likely find one of them oily.
Two general rules of engine smoke I find to be true.
1) - If it smokes at idle and start up its the valve seals gone bad. The high vacumn pulls the oil through the valve seal and down the guide.
2) - If it smokes when under a load, its the rings. The rings are loose and at high rpm they can't seal to the cylinder wall which lets oil in to be burnt.
The valve seals are replaceable with out real major work. The rings will require total tear down and rebuild.
I change valve seals on my 168,000 mile Dodge 318. It was using a quart of oil every 300 -400 miles. The new seals cured it, 2000 miles and no oil use! The oil is staying cleaner now, not that black nasty stuff.
Let us know what the plugs look like and what your plans are. Everyone here is willing to help! Joe H. | | |
