    2008 tahoe 5.3l in need of desperate help

    If the cam is original and the lifters are new then that could be causing it. Lifters wear to the cam.

    I did try to start it without the serpentine belt on to eliminate that possibility.

    P0641 after during oil pump Install

    2007 GMC Yukon Denali 6.2 So I attempted to install a new oil pump but was interrupted half way and had to stop. I removed the water pump. I removed the power steering pump rack assembly (5 bolts) and pushed it off to the side. I used a factory gm puller and tried with that along with O'Reillys...

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    Does anyone know if th camshaft is a 2 bolt or a 3 bolt? apparently auto zone, napa and O'Reilly all have different answers lol. I was kind of hoping to have it in my hands before tearing it apart. O'Reilly says 540 dollars. Online is like 330 but want to dot my i's

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    I did the down hill and it didn't help. I also overfilled a few quarts and that didn't help either. So I'm assuming the oil pump is completely shot.

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    Well I will make a party of it and order a new cam when I do the oil pump. Now I just have to decide if I should do a stage 2/3 upgrade.

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    Here is a question for everyone. I looked at the cam right before reassembly and I'm noticing some marks. Wondering if I should replace this cam? Should I consider like a stage 2/3 kit?

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    Well I took my time and redid the valley pan cover, gaskets and cleaned everything. Oil pressure is reaching higher now into the 40-45psi range on startup but still drops considerably too low after warm so I will tackle the oil pump next week. I was hoping to get to it today but that won't...

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    I am also wondering if my oil leak will minimize as well. I just wish I knew why the previous owner went through the trouble of removing the intake and sealed the edges but didn't replace the gasket. I was told the valley pan didn't need sealer around it. I was contemplating using some extra...

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    So here we are. I decided to do the valley pan first. I'm glad I did. Every bolt on the valley pan was loose Absolutely no socket wrench was needed. Every last screw was unscrewed with my fingers. I used a pry tool and patience to get the valley pan up. Every last square inch had black sealant...

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    You can see the black silicon around the valley pan. I will just feel better with a new gasket on it.

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    So I will be replacing the oil pump this weekend but wanted to update something I found kind of interesting. I ordered a new pickup tube gasket at O'Reilly instead of Napa. It was a felpro and it's red. I will give a picture below. It seemed thicker so I bought it and brought it back to Napa...

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    I dropped the oil pan and redid the seal, scrubbed the pan and cleaned the pickup tube at the same time. Dropping the pan wasn't as hard as it seemed. Front dif drop wasn't fun but me and my son was able to fight it

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    Thanks for that picture. When I pull the oil pump I will take a similar picture and take my micrometer and do measurements. Because if napa gave me the wrong one makes me wonder how many others are fighting this

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    I'm wondering if I was given the wrong one. I will verify thickness this weekend. Might as well do the gaskets under the plenum and such as well. This is why I like LS Engines, for the most part aren't that bad to fix

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    Do you know if the oil pump connects directly to the pickup tube in the oil pan?

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    So I have the common dreaded low oil pressure. I replaced the pickup tube ring and still have low oil pressure so I'm about to tackle the oil pump. Does the pickup tube mount directly to the oil pump? Asking because I would like to see and feel the fitment again of that O ring. I have seen...

    07 Yukon Denali inspection cover on Bell housing

    Yea that was a nightmare fix! Original owner went to Valvoline and they overtightened the oil filter so bad I almost had to impact it off! I had to do 1/8" increments and most all that oil splatter is from the filter having a slice in it from being too tight. Hardest oil filter I have ever had...
