Got bored sitting around the house and pulled the Jag into the garage.
Checked compression while it was still hot: 70 and 90.
Here's the thing, it started and ran and I drove it into the garage.
Last winter it would start and run, but obvious less power as it warmed up and then once warmed up it was very hard to start.
I checked the compression tester and it was reading about 5 PSI low.. So actuals would be 75 and 95. Still way low.
Pulled the cylinders off and measured the best I could with the tool I have and it seems like it is close enough, but I can only measure the ends. Not the middle. Pistons would move about .5mm (yep, .5) when not at the bottom or top, so I'm guessing just wear and tear.
Pistons were new 2 years ago to make it last this long, but I'm sure I need cylinders. Yes, this is the same Jag I posted about last winter.
