Decided to do a compression check and got some bad results. Did the compression test a second time with the same results. Only number 2 cylinder had a good reading.
Cylinder 1 = 95#, 2 = 160#, 3 = 145#, 4 = 140#, 5 = 140#, 6 = 130#
To find out where the compression losses are, I then did a leak down test. Did the test with 100 PSI, Number’s 1, 3, 4, 5, & 6 had serious leakage past the pistons. I could hear it blowing by clearly at the PCV tube. Didn’t hear anything in the intake or exhaust ports. With number one cylinder being real low on the compression test I continued to look for a reason. Next I pulled the shields around the bottom of the motor. Found number one also looks to have a head gasket leak. Here’s a picture.
I guess it’s time to pull the motor and open it up.
