    Passenger side head not getting oil

    I spoke too soon... Oil pressure gets below 10psi when hot at idle, accompanied by a tapping sound. I'm guessing this sound is coming from the rockers not getting enough oil due to the low pressure. What's the fastest way to drop the oil cooler on a 4x4 truck? I need this working by sunrise...

    Passenger side head not getting oil

    The oil pressure is now sitting pretty at 25-30 psi cold at idle, and the head is now getting oil. I did two things that may have moved the needle. First of all, I installed new lifters all around. Second, I managed to spray seafoam directly into the relief valve through the bottom of the...

    ARP lube on stock head bolts

    I've recently just installed the heads on my truck, and come to find I may have made a critical mistake out of habit. When I've done heads on different engines before, I've always used ARP head studs and ARP fastener lube on the threads and washers. However, this time I used OEM replacement...

    Passenger side head not getting oil

    It's true. I have a proper gauge that I'll be using when I get it fired up in the coming days. I'll give true numbers then. We definitely know that the passenger side bank isn't getting enough oil pressure to push oil into the head, but that's it. I'll run the engine without covers to see...

    Passenger side head not getting oil

    I took the lifters apart, and they had no signs of sludge or clogging of any sort. They were clearly worn internally, but not worn enough to have the problem I'm having

    I certainly hope you're right. I'm going to take the oil cooler off tonight and check the condition of the relief vale too and report back

    There's two valves, the relief valve and the bypass valve. Wouldn't the bypass valve simply bypass the filter and not cut oil pressure?

    Passenger side head not getting oil

    Good idea. I'll have to find a portable air compressor to check this. Oil cooler has been removed yet. My next plan is to remove it to clean and shim the pressure regulator. I'm just trying to get the critical components that are accessible to me sorted before I start it up next. Could the...

    Gotcha, thanks. That's exactly what I thought about the lifters. But if it just so happens that every single lifter on that side is clogged up (extremely unlikely), then I suppose they wouldn't let oil get into the pushrods

    Passenger side head not getting oil

    Yeah, I inspected the lifters. They were clearly old, and quite scored on the bearing surfaces, but they were straight as were the pushrods. My next attempt may be to clean and shim the oil pressure regulator. I have yet to find a good write up on the process of removing the filter housing...

    Passenger side head not getting oil

    The heads are still off so I don't know, but the dummy gauge read fine. I'll be putting a real pressure gauge on it once it's running

    Passenger side head not getting oil

    Could low oil pressure cause that much difference in oil flow between the two heads?

    I could also try blasting compressed air into the galleys
