Thread: White smoke from breather and oil drops formed

Check your valve adjustment first, make sure valves at #3, 5 & 7 are not tight. Re-check compression, on low cylinders squirt some oil in each cylinder (one at a time) and re-test the compression. If the rings are leaking the oil will temporarily seal the rings and the compression will go up.
If the compression remains unchanged, make sure the valves are closing by slightly loosening the adjustment and re-test (make sure the valves are slightly loose on their closed adjustment). If the compression is still low, remove the rockers on the low cylinders and pressurize the cylinders (one at a time) with compressed air through the spark plug hole and listen for where the air comes out. If you hear the air through the intake port, intake valve is not sealing. If you hear the air through the exhaust, exhaust valve is not sealing. If you can't hear the air exit or you hear it through another cylinder, you have a blown head gasket or cracks.
