Another problem is low engine oil or low oil pressure. Disconnect the air discharge line from the air compressor. Compare the results of test one with test two. Get shopping advice from experts friends and the community.

To determine if a defective air compressor is causing excessive crankcase pressure perform the following. H 2 o 0 75 kpa check the air compressor. Perform a crankcase pressure test and record the test results. To try and find the leak do the following.

Repeat step and record the test results. To determine if an obstructed or damaged breather is causing excessive crankcase pressure perform the following. Pulley out of alignment. When this happens the connecting rod bearing furthest from the oil supply line will be the one that burns out from lack of lubrication.

If you plug in the compressor the pressure switch response to the air leak and dropping compressor pressure will be to start the compressor again.
