Hi,
I'm looking at a -6 that had on compression test on 7/24 and the results were: 1-160 2-170 3-155 4-150 5-170 6-110 That car has sat for quite a while but the owner says it runs well. He asked the same shop to test the compression on 7/31 and now cyl #6 is showing 140. Can compression improve when taking a car out of storage and driving it? Or is this just sloppy work on the shop that did a PPI? -Steve |
