    Two bad new oil pressure sensors? Tell me I am wrong.

    3rd sensor received. 19 ohms resistance out of the box. Gauge now shows 0psi with the key on, 38psi at cold startup exactly like the mechanical gauge I had used to check the pressure before. After a few minutes when the idle settled back down to normal it was 32-34psi which is also the same...

    Two bad new oil pressure sensors? Tell me I am wrong.

    The original sender is back in place until another arrives and it works as before. 0 psi when the truck is off, truck running =15psi. I don't think I caused an issue with any wiring, but I appreciate the suggestion.

    Two bad new oil pressure sensors? Tell me I am wrong.

    I noticed my oil pressure gauge reading low last week. At cold start up it was just over 15psi and dropped to maybe 5 psi when hot. This had me concerned so I took out the sensor and hooked up a good quality pressure gauge. Gauge shows 38psi at cold startup which made me feel better, so I...

    Ignition Timing for First-Generation GM V-8 Engines

    I bought my truck last fall and have been busy dealing with a ton of other problems with the truck. Well yesterday I finally decided to check it and was confused with the results. Vacuum disconnected initial timing was 11 degrees at 750rpm. Revved it up to 2800rpm and it was still 11 degrees...

    Oil pump options and questions

    Starting to look into some low oil pressure issues. I am hoping it might just be a bad pressure sensor and will try to get a mechanical gauge on to confirm pressures tomorrow. I was looking at the Melling site to review their options and they list 3 different High volume pumps. Does anyone...

    What have you done to your square lately??

    The truck has had an oil leak since I bought it. Couldn't locate it, but while working in the carb the other week I noticed a wire stuck under the back edge of the drivers side valve cover?? Previous owner was obviously not paying attention the last time he had the valve covers off and pinched...

    What have you done to your square lately??

    The list of things I have found wrong with this truck since it's purchase last fall is long. But I wanted something to get me off the couch and out in the garage and it has certainly accomplished that goal. This is my first older truck and I have a lot to learn. Many of these issues would have...

    What have you done to your square lately??

    When I bought this truck it had a bit of a stinkbug stance. Over the winter it got new rear leaf springs which didn't help the situation. Tonight I finished putting some longer shackles to help reduce the gap in the rear wheel wells and level the truck out. The shackles on the truck were...

    Steering box Input shaft seal question?

    I have a leaking input shaft seal. I picked up a seal kit over the winter and decided today I would get it done. Managed to remove the old seals and grabbed the new one to discover it was the wrong size, Too small?? Re checked the Napa and the Edelmann site to see if I screwed up when...

    What have you done to your square lately??

    After discovering my G80 locker had broke I finally finished up the rear axle with a replacement open diff. I haven't setup a rear end before, but it wasn't terrible after getting some tools and making a couple of setup bearings. The rear had a lot of metal in it as the broken G80 locker teeth...

    What have you done to your square lately??

    Spent the weekend getting the axle back under the truck, new rear brakes fitted, new brake lines and cables run. Decided to remove the diff cover and clean out the old fluid and get everything sorted before I move on to other items than need to be fixed. I expected to find an open diff, but was...

    Automatic slack adjuster lever question

    Were there any years that GM didn't put automatic slack adjusters on their rear drum brakes? I am getting the brakes on my 1980 step side back together and discovered there was no slack adjuster lever on my truck. Every picture I have seen of gmc/chevy show these included. Mine are 11x 2-3/4...

    Changing from 80 square headlight back to 74-78 round headlight question.

    I don't like the 79/80 round with the bezel that surrounds the turn signal. If I am going to change mine I want to go back to the 73-78 style. I guess I will need to keep an eye out for a round headlight rad support. Thanks

    Changing from 80 square headlight back to 74-78 round headlight question.

    I have a 1980 square headlight and would like to change it to the 73-78 round headlight. I understand I need the bezels, round headlight buckets and all the other small screws adjusters etc, but was unsure if they would work on my existing rad support. I thought I read a post somewhere that the...

    A new Squarebody owner in Nova Scotia.

    I picked up my first Squarebody a couple of weeks ago. 1980 Stepside in good condition, but as always they have something to fix. Hopefully I can get these items sorted before spring comes around.
