Hi All,
I hope your season has been well. The Huron meet looked like a blast. I wish I could heve been there.
Well, I have a slight problem with my port engine. 427 power. It was running a little rough at idle all year and the old paragon was rattling. as the rpm's increased it went away but there was still a bit of a whirring noise. I thought maybe a damper plate or somthing. Unable to tune the rough idle out by a valve adjustment, timing check, carb idle screws, etc., I pulled out the compression tester. 7 cylinders were between 115-145 psi. I know not great but managable however number 3 cyl - zero psi.
OUCH! Funny thing is the engine runs ok otherwise. Starts right up and runs good. Checked the compression several times and did the #4 cyl again to make sure I wasn't going crazy.
Pulled the valve cover and checked the valve train. All looked good and the #3 valves seem to be seating ok (rockers clearance at tdc. A new oil slight seapage/leak has also shown up at the intake manifold-block gasket right over the bell housing.
I'm thinking the next step is to pull the head. Any thoughts?
Regards,
George
