Hi John!

 

Please check your compression with engine hot with throttle fully open on all cylinders. Based upon 4 to 5 compression strokes per cylinder. Min reading 175lb/sq in. Vacuum reading S/B around 14Hg (850 to 900 RPM) at tick over measured from servo take off for a CR engine.

 

Note there are 3 different vacuum readings for the 3 types of PI engines!!!

 

For OEM part number for the camshaft this is engraved or stamped on camshaft between the lobes, 311399 refers.

 

Then advise us!

 

Bruce
