When I bought my 55.2 3600 the previous owner had the cluster out and the oil pressure line to the gauge kinked closed. Running the truck up onto the trailer and off into the shop oil was leaking quite a bit. The original oil pressure gauge is shot so I installed an aftermarket gauge, fitting on the head (235 6cyl) and oil line. I can't get an oil pressure reading although when I started the truck after changing the oil filter I didn't have the nut tight enough and made a hell of a mess. I'm wondering if possibly the aftermarket adapter at the head screws in too far?? I'm going to try to track down a gauge I can screw right into the head to test it and / or try an electronic gauge and sender.
I'm going to adjust the valves so thought I'd run it for a minute to see for sure that I have oil up to the head. With the valve cover off there looks like plenty of oil was in there.
Any input?
Thanks
