  • Hello John,

    My midget 1500 engine goes to 100 PSI in 900RPM!!! Later pressure falls but not that much. As soon as I accelerate pressure goes wild again... I have changed oil (10W50 Castrol) & oil filter GFE150 twice. Bought new pressure relief valve (Spring, little piston) but this is not the case. I think because of this pressure now I have crankshaft oil leak :( Front & back. I have put engine flush now & will try to clean rocker shaft & change oil again. What do you think problem can be???

  • I'd renew the oil/filter, and run the starter-motor with the plugs out until pressure is seen on the gauge; replace plugs and start the engine.

  • very informative, however, I have a 77 mgb with a new engine, sitting dorment for about 14 years...never cranked over, but hand spun with about 1 quart of oil in pan. What is the best way to prime oil pump prior to initial start-up?

  • Hey, thanks! I was worried that my pressure dropped to 40 psi at idle. Not anymore.

  • you're a good teacher. Where do you teach and how can i sign up?
