Looks like we'll be doing some work to Sean's Cougar's engine in the near future. Sean took it to Dyno Day a weekend or so ago, and while on the dynamometer it coughed up some coolant and started to run rough.
I was going to do a leakdown test using Sean's new leakdown tester,
but decided first I might want to do a compression test.
Then I decided first and formost I'd do a coolant pressure test.
I never got past the coolant test. With the plugs out, I can hear pressure leaking from the cooling system into at least 2 cylinders, one on either side, 2nd from front. Wahh!!
