Thanks for the video was very helpful I'm going to put an internal gauge in just like you did so I can get a better reading of what's going on with mine

Thanks for the video. I have a 05 Tahoe, 5.3 with about 300,000mi and a few months ago started having oil pressure problems. I've owned this vehicle for about 10 years and it never had what I would call "good" oil pressure, but I had to do something when it started dropping below 10psi at hot idle. I thought the pickup oring was bypassing so I did similar to you, bought a new (stock) melling pump M295 with pickup tube and orings, new cam sprockets and chain and put it on. The old pump had some gritty debris in the relief valve which I thought might have caused it to stick open and the pump housing and cover showed significant scarring and wear. After putting on the new pump I immediately had good oil pressure for the first time since I owned the vehicle. But after driving for two weeks, pressure started to fade again and now after about 1500 miles it is back to the same below 10psi at hot idle condition as before I worked on it. I cleaned the pan thoroughly when I had it apart. I also lubricated the pump before I put it on. Engine runs quiet and doesn't use oil. After replacing the pump, I was sure it was going to be fixed for another couple hundred thousand miles, but now I'm wondering if the cam bearings are wore out. Mine is a rwd, so I dont have the extra work of removing and putting back the front differential, but I'm a shade tree mechanic without a shop or lift and I'd rather not throw more money and parts at a $2500 vehicle if its not going to fix it. I'm curious how the M365 pump has held up for you after some months of use. Thanks again!

Did you do the pump alignment procedure? Or just bolt it on and go? Im about to do this job myself

@jonesrj Жыл бұрын

@171apples171 no, I just followed Mellings install procedure. I went ahead and bought the later model pump for afm engines. I put it on about a month ago, this time I found a significant amount of metal in the pan. Cam bearing is undoubtedly wore out, but I have 40psi at 1800rpm. At hot idle pressure is around 10psi. I will drive it as long as it will last like that.

@@jonesrj these engines are famous for having a cam bearing walk out once its walked far enough it uncovers the oiling port from the cam bearing bleeding alot of pressure as now there will be no oil between that bearing and the cam and simply bleeding out back to the pan.

I subscribed to your channel! My 2006 Silverado Z71 (187k miles) with the L33 aluminum block 5.3 has about 28 psi at startup, goes close to 40 warmed up and drives between 30 and 40 in town and on the highway ...... i rev it up and it never goes any higher than 40 psi..... oil pressure sensor was replaced and i had no filter screen installed under the sensor that i could find. Recently my oil pressure will jiggle around at 25-30 or so back and forth on occasion. Guess i will replace my pickup tube o-ring and go from there. Excellent video, thanks a lot, Johnny Cash (that's my truck) and me really appreciate it!!! I've had him 5 years now.

Good video thank you i have a 04 2500HD 6.0LS with 263k + miles runs great im thinking of replacing the same oil pump and timing chain as a preventive General maintenance. I’m having small issues with a dry start for about five seconds other than that runs quite smooth no knocking or anything else. Your thoughts sir 😀

I'm replacing the pump on my 05 5.3L. One question after watching your description of the pressure relief valve ratings. If they are designed to open at 20psi, then why do many (good) engines idle at 40, or reach even higher at higher throttle? Why doesn't the open relief valve hold the pressure at a steady 20 psi at all times?

@macsgarage Ай бұрын

@talentsfaith6641 it's all about the leakage. The pump produces more volume than can be dumped from the relief port. The looser the engine the more oil is lost through the bearing areas which the allows the pressure relief in the pump to actually control pressure at the relief point. Hopefully that makes sense.

Where are pumps located

@timbriand2426 Жыл бұрын

Question for you. I have an 05 stock 4x4 6.0. Losing oil pressure goes up and down as far as almost 0. I have no loss of power and no noise but if I let it sit for a day or two. When I start it, it will smoke a bit and then clear out. I have 208k on the truck. Thoughts on that?

@daviddenson3324 5 ай бұрын

I assume you already tried a $10 oil pickup tube o-ring before doing all this? Those worn out oil pickup tube o-rings can be replaced by just dropping the oil pan and of course the pickup tube itself and im sure you know that already. Those oil pickup tube o-rings are a common issue after so many miles on these tucks and will cause lower oil pressure.

@daviddenson3324 kzbin.info/www/bejne/naiogZl4o9uCmMksi=QvNROv19jWqrHE6p It's a lot of labor(especially in 4x4s) and an additional oil pan gasket to try just the o-ring.

What if you just take those 4 bolts out of the pan , remove the timing cover , reinstall , then remove oil pan ?

@macsgarage 9 ай бұрын

The pickup tube bolt would be in a very awkward location. You may be able to do it. I have done this a few times and have pulled the pan.

I’m doing a rebuild on a gen3 5.3 with new bearings all the way around but there are so many oil pumps that I don’t even know what to get, I’m thinking on the 295 but still undecided since I’m going to put an aftermarket cam and I don’t know if that’s going to affect the oil pressure, should I stick with the 295 or get one of the other two, thx

@macsgarage Жыл бұрын

The cam shouldn't really affect oil pressure as long as the journals are the right size. If your clearances are all in spec the 295 or 295HV should be plenty of oil. If you want a little more pressure at idle the 10296 is a performance option. The 365 will likely be to much oil flow for a fresh relatively stock gen 3. To much oil robs horsepower and may cause oil filter and gasket problems. I used the 365 because my engine has issues.
