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

Bill An oil pressure line could be attached to the head on the distributor side (a cob-job installation): into the hole on the upper middle of the head - the hole that would normally have a square-headed plug in it (a hole into the oil-feeder journal that goes up to the rocker arms assembly). Most likely this would not be a "good reading", being near the "end of the line" of the lubrication system. | | | | | Joined: Mar 2013 Posts: 45 New Guy | | New Guy Joined: Mar 2013 Posts: 45 | Yes the oil pressure line to the gauge was screwed into the head. Which oil filter line should I 'T' it off from. The one coming out of the rear of the block or the one more toward the center.

The original may not be the same as your aftermarket.
