    Weird Popping Noise

    I have an odd popping sound (sounds like an a/c compressor cycling on and off or a brake pad shifting) coming from the left front. It seems like it happens when there is a shift in the suspension either from hitting the brakes or turning in a parking lot. The front shocks were just replaced and...

    Weird Fuel Pressure Issues

    Could my tuner have possibly set me tune up to try and get 58 psi out of it and the computer is trying to compensate?

    Weird Fuel Pressure Issues

    I replaced the MAF with a brand new Delphi unit. I’ve smoked both the exhaust and intake to check for leaks and can’t find any. Both upstream O2s are swapping pretty consistently from .1v to .9v without any weird spots on the graph

    Weird Fuel Pressure Issues

    Hi I have a 2004 Tahoe with a 5.3 flex fuel engine. It has a small cam, long tubes, and a cold air intake. The issue that I’m having is that at idle my fuel pressure is only showing about 42-44psi with my regulator plugged in and only about 52psi with the regulator unplugged. I’ve already...

    Low Oil Pressure at Idle When Warm

    Update to everyone. Got the Tahoe fired up and running. Checking all fluids and moving harness around and the truck turned off. Had a buddy crank the key while I moved the main harness across the intake and the truck started back up. Took the intake off thinking I had a ground loose I found the...

    Low Oil Pressure at Idle When Warm

    Installing cam bearings you have to have the engine out or at least I would take it out due to the fact that you need to be able to make sure that the oil holes line up from block to bearing. Changing the cam itself you can leave the engine in and just take the radiator out and you have enough...

    Low Oil Pressure at Idle When Warm

    Thanks! I’m thinking that it could be a ground issue on the drivers side because I know I didn’t put the ground back on the head because I bolted it with the ground strap to the bellhousing. So swap that around really quick and then on to looking at the crank sensor

    Low Oil Pressure at Idle When Warm

    If the gauge was pegged out at 80 most of the time and then dropped off to 0 sometimes he shouldn’t have touched the oil pump in my opinion. I would’ve replaced the oil pressure sensor first and then went from there. It’s quite possible that you spun cam bearings like my engine did because after...

    Low Oil Pressure at Idle When Warm

    It was steady sitting at 19-20psi. I pulled everything apart thinking I had a weak oil pump and went to slide the cam out and it wouldn’t budge after 3 lobes

    Low Oil Pressure at Idle When Warm

    Another update. I got the whole engine torn apart and was replacing the cam at the same time since I was there you know? Well the cam would only come out about 3 lobes and then it would stick and no matter what I did it wouldn’t move. Took the oil pan completely off and looked up through the...

    Cam Swap Question

    When removing the camshaft to install a new one do you have to remove the valve covers and rocker arms if you aren't going to be replacing the springs?

    Low Oil Pressure at Idle When Warm

    Update to everyone. I swapped the oil pressure switch with a known good switch off my buddy's truck and it still reads low. Looking at replacing the oil pump

    RockAuto Oil Pump?

    I'm looking at replacing my oil pump in my 2004 Tahoe 5.3 Flex Fuel and I've been shopping around for a while for a high volume oil pump and the cheapest Melling I found was on Amazon and it costed $105. Well looking around on RockAuto for gaskets and other little things I might need they have...

    Low Oil Pressure at Idle When Warm

    This is probably a separate issue and not related to my low oil pressure issue right?

    Low Oil Pressure at Idle When Warm

    So are you thinking I might need a new PCV valve? Or the whole valve cover due to the baffle in it? How do you recommend checking it all out?
