    Low oil pressure

    After much research through the engine compartment, my mechanic discovered that when he moved the wiring harness when he was removing the engine the insulation on wires leading to the starter connection cracked and caused a short. It also affected the power to the pcm which was causing the...

    He pulled the engine and cleaned everything. I purchased the parts (crank, main bearings, rod bearings, and cam bearings, head gasket set) and he did the teardown and reassemble.

    Low oil pressure

    This didn't happen two weeks after I purchased it. I bought it in April and this happened in September. During that time I put over 18K miles on it and added over 3K idle hours.

    Low oil pressure

    Well, now it seems as though there is some sort of electrical issue and he thinks that's what is causing the rough idle from yesterday and today it just died and wouldn't even click when I turned the key

    Low oil pressure

    Well finally got my Tahoe back after my almost complete rebuild with a new crank and bearings all the way around. Pressure is good. Haven't driven it much but it's a little rough at idle. I've never had an engine rebuild before so I am not sure if this is common or not. Mechanic indicated it...

    Low oil pressure

    I would like to upgrade, however, I have to have this specific vehicle for my work and it has been down for the last 6 weeks so I haven't been working, and this wasn't a planned repair.

    Low oil pressure

    Yes. It's getting new cam, rod, and main bearings. One of the cam bearings had spun, but there is no damage to the cam.

    Mechanic said that the oil was fairly clean, this time, when he drained it. Since there is obvious wear new oil and filter are going back together.

    I stand corrected. There was a relief valve in it. Since the engine has developed a knock we are going to go ahead and replace all the bearings along with that relief valve and hope that fixes the problem.

    Low oil pressure

    The mechanic said that there was a port fairly close to the drain plug, but there was nothing in it. He did say that he cleaned the pan out around it though.

    Low oil pressure

    The oil filter and oil have been changed about 5 times since this started. Most of the filters were Fram Toughguard filters, but there was one NAPA filter and now the K&N.

    Low oil pressure

    After the installation of the 2nd new oil pump and pickup tube, complete with new o-rings my pressure remains the same. 20psi+- at 2k rpm. <10 psi at idle. Tried parking on a significant incline at idle and nothing changed. Since the oil pressure dropped the first time it has developed an...

    Low oil pressure

    When I posted this the new pump had already been removed. The new pump came with a new pickup tube and o-ring. My mechanic is supposed to have it changed out in the next day or so and hopefully it will fix the issue. He has drained the oil several times since this happened and the last time...
