I have a 05 Tahoe z71 I just put a oil pump in and I didn’t have to remove the front differential i just lowered it Down without removing the axles just the nuts and bolts and let it hang without any damage and the pan was removed easily.

Melling 10355HV- high volume will increase the hot idle psi by about 5psi and the pressure springs could increase running pressure past 40 psi till the relief valve in the pan opens up. Highly recommend the hv pumps for higher mileage motors. If plugging up the releif valve with a m14x1.50 oil plug, use a standard pressure spring to not over pressure the system when running at hwy speed as it will trigger a code for high pressure. Generally the cam bearings open up more through wear reducing oil pressure. Replacing the o ring helps and clean the oil pressure sensor screen if applicable too. Fyi, the new cam bearings in the market are slightly wider for better support of the cam at .775". Replace cam bearings with updated parts.

The Chevrolet LS oil pumps won't like to pump dirty oil it causes excessive wear on the aluminum housing of the pump, I had to change the oil pumps on a fleet of buses I was working on due to lack of oil changes. I used to high volume low pressure m55 oil pumps I don't have to drop the oil pan tricky getting a bolt in for the pickup.

The two O-rings on the oil pan gasket also can leak and cause oil pressure loss and also cam bearings if it has high mileage can also, but 98% of the time its that O-ring right there:P I have to do this on my 2003 GMC and got to replace intake manifold gasket as well bummer!

@rickn8or Жыл бұрын

I had an '01 GMC that the oil pressure would drop to zero at idle when cold, fine after warmup. Turned out to be the two O-rings in the pan gasket that carry the oil from the block to the filter and return. They were cracked and passed oil from one to the other. Replaced O-ring and pan gasket, everything still fine when I sold the truck at 395K miles. Sort of immaterial, since you're going to replace the pan gasket anyway (right?), but it's still something to look for.

Apparently you can add 3 qts of oil to your motor jack up the back of the truck 2 foot and if your oil pressure comes back then you know it’s that stupid oil ring. I’ll be doing this test tomorrow on my 2012. Do you think that a damaged/old oil pump would also effect the AFM/DOD lifters???? Causing them to collapse I mean those things are temperamental. I have a 130k on my truck no issues yet but I don’t want any if I can avoid it

I have a 2007 Tahoe 5.3 engine. The valve lifter for one room got stucked I replaced it and all was fine. I drove the car for some time and that same room the valve lifter got stock again but before that I noticed low oil pressure. Immediately I noticed the low oil pressure I pulled over the car check to see if there was a physical abnormality of which it was not. Drove the car for about 5 miles the the low oil pressure signal came again. Please what could be the possible cause of this valve lifter being stock?

The oring can harden and loose seal between pump housing and pick up tube; it also is rumored to have been pinched/damaged upon install. I had a 2005 6.0 oring had hardened; Son had 2006 5.3 oring was split in 2 different places. Put melling hi psi pump in 5.3/melling hi vol-hi psi pump in 6.0 and replaced both orings The lifter was ticking in 2006 but this fixed the issue

My oil pressure drops over time. So once the truck is warmed up the oil pressure will be at 35.. over time of driving it awhile it’ll slowly drop to 5 and that’s when the truck starts to boggle. Any ideas? I replaced the oil pump few months back and the oil pressure is still doing the same thing. Did I replace the wrong part?

@ryanbuck3789 Жыл бұрын

Have you heard of the oil pump, making a knocking noise or almost sounding like a lifter noise, And it Sometimes comes and goes? I have a 06 Silverado 2500HD w/t with the 6.0 The truck never had an issue until I did a oil change and put the Lucas high mileage engine oil stabilizer in it the very next I went out and started it to let it warm up before work and I heard it from inside the house it was sounding like the lifters were just hammering and it had like no oil pressure so I flushed that oil out multiple times but it never fix the problem. It’s been years now and that tick is still there from underneath the hood it sounds like it’s the injectors but I doubt i because the oil pressure is low and goes up to maybe 3040 when you’re hard on the gas. It’s still runs just fine. Smooth as ever but the tick drive me insane sounds like my motors going to blow. I did the O-ring twice it’s good that’s not a problem I just don’t see how that could happen overnight but then again, we are things have happened. A local fleet mechanic is telling me it’s the oil pump making all the noise and he changes them out like a few a month on their fleet. It’s just weird when you’re getting on the gas it almost sounds like a cat go through a 64 impala with round, cut exhaust tips and straight pipes.

@@aaronzavala4336 sounds to me like something isn’t right in it with all new bearings like that. You should have a lot of pressure I would think it should have around 40 to 50 psi when it’s running and warmed up when it’s cold we just built a 6 L and put a high oil pressure pump in it and it had 120 psi we had to take it back out if it’s new lifter, it shouldn’t be making any noise.

Went to pick up, oil light came on, with low oil pressure stop engine now.. After checking the oil, I noticed they put 2 quarts over the needed oil.. I had them drain the extra oil.. We've changed the oil pressure sensor and screen thingy, but still having problems.. I have no engine light on, once started I have 40 pounds of pressure, after about 30 secs , I receive a chime sound, oil light on, low oil pressure reading, and drops to 0 pounds.. Any tips would be greatly appreciated,

Installed melling M355 in it psi went to 40 @ speed 10 at idle. Truck was neglected when I bought it, suspect worn brgs.

@techo61 Жыл бұрын

OH NO NO NO. Do not for a second believe the pump 'self centres' by rotating the crank, the outer rotor floats and the crankshaft does nothing to centre it inside the housing. Using this method will most likely end up with another pump failure due to the gears not being centred and a lack of lubrication all the way around the outer rotor and its aluminium housing. The only way to centre these and the OEM Internal Gear Pumps with their oversized mounting holes (no locating dowels) is the remove the cover and use shims on opposing sides of the outer rotor. kzbin.info/www/bejne/eYimepeefJVngrs Otherwise a good video, cheers.

Lol old information. That may be true for those big name brand overly expensive pumps, but melling is just like you said. Just rotate the crank. Melling will tell you the same thing.
