That's because warranty is void if you remove the cover to shim. Melling didn't have the 360° spin procedure in the past. I'll shim every time regardless of warranty.
In my opinion it takes 10 minutes to throw some .002 shims in and it’s that piece of mind that it’s done perfect. Definitely worth the extra few minutes.
If you lube it all up with assembly oil it’ll leave almost exactly the same gap as the shims and rotate the crank 360 and prime. Faster easier and ends up with the same results. Just my opinion 😅

Just finished up my engine rebuild on a GMC 6.2 L, followed melling's recommendation of installing oil pump hand tight spin the engine over twice and then torque to spec. Now some are going to tell me I'm crazy. I got done with all of my bottom end, timing chain and camshaft installed, flip the engine upside down and poured about a half a bottle of assembly Lube into the oil pump itself. turn it over twice to distribute the assembly Lube through the pump installed the pickup tube with the new o-ring and poured oil down the oil pickup tube until it filled up and started to overflow with the engine upside down, rotate the engine again and suck the oil down, took about a half a quart before it filled up the main Galley and started to come out where the barbell diverts the oil to the oil filter. set the oil pan on bolted it down and torque to spec. pre-filled my oil filter and screwed it on then flip the engine over and poured 4 qt into the lifter bores. I spin the engine over again by hand until I see oil coming out the lifter bores. Now I'm ready to drop my lifters in and torque to spec and finish engine assembly.
I use a new garden sprayer , put in three qts oil , hand pump the pressure , then you have a built in valve to regulate the flow while hand turning the engine over while on the engine stand.👍
Thanks great information no extra sales pitch! That’s how they sell stuff also best stuff best prices and they will help you get what you need. I called them when purchasing a clutch for a build. I couldn’t be happier with the results factory feel hold power well. It was actually 700 dollars less then the one I was looking at too. The salesman informed me that with my power level a stock ls7 clutch was perfect for what I needed and would drive like a factory clutch because it was in fact a factory clutch. Thanks a million this is really a good company.
Wow I wish I would have known this when installing a high volume oil pump in my LS 5.3 motor , but great informative information for next time thank you
Shimming seems like a good idea. Consider that the crank is not up on the oil film when it is shut down. The crank will center its self in the bearings when spinning on the oil. what about using something like a .003 on top and a .002 on the bottom? .0025 sides? Also the accessory belt will be lifting the crank snout. Oh ya and the blower belt too.

On the LS engines, the big allen is a coolant plug, the smaller one there is the oil galley plug. cimg9.ibsrv.net/gimg/www.corvetteforum.com-vbulletin/1024x768/ls1_ls2_231_61065f23fb65de823257699f4f4e6eea5a243d97_8eaebde400fc20e213b44aef807f471c11716ee1.jpg If you're talking Gen V LT, the top is the oil supply, the bottom is the oil return that just drops right back into the oil pan.

@@Sdpartscenter Thanks for the INFO. Yes, I was talking about the Gen V LT. I did take out the top one, and put a small strip of cloth in the hole. and there was trace amount of oil on it, 👍🏼. I have just completed a Cam Head swap from Texas Speed, will be pushing some oil thru the supply side, and excited to get this thing fired up. Thanks for your Help!!
Hi, Thanks for the video. I have the same problem p0016 cam crank correlation error. Did replacing the tensioner fix the issue or was a new timing chain fitted? Thanks in advance.
I put the oil pump on a 2006 Chevrolet Silversdo 5.3 new at the moment what it does is when I start the engine it takes a little time to raise the oil pressure the horses sound and when the engine is cold when starting there is blue smoke what could it be? thank you.
Easiest method to remove spark plugs.........not so sure in the f body ls1! Cylinder 6 was a nightmare. Cylinder 8 was actually OK when I went under the car to change it. I have heard of people being able to change the number 8 spark plug from the top. They're more clever or more patient than I was.
I'm doing a AFM delete on my 15 6.2 Silverado , this is my first time in a LS/LT base engine. I have watched videos of guys walking the timing chain onto the top gear to avoid removing the oil pump. I'm concerned about doing it this way. I have read aligning the oil pump can be an issue. I see these alignment tools but not sure how they actually work. Looks like they just do up and down ,not side to side. Any thoughts? Your videos are a life saver to someone like me. Great information , very much appreciated. 👍👍
Not much info here about replacing a pump on a 4WD 2005 K1500 without dropping the pan. ..... I got it out OK and got the right o-ring (green from Melling) and I'll shim the outer rotor just to make sure it's OK..... The engine has oil through it already from running just three days ago and I'm changing the pickup tube alignment "device" to make it almost impossible to let the hold-down bracket swing 180° to the previously unused bolt hole. ......... FWIW--- yes --- the pump CAN be changed without taking the pan off ---- just very frustrating and a little wiggling and gentle persuasion. Be sure to not change the oil until you have had the engine running again --- that way it won't be filling the filter for too long.
Great vid, priming a dry sump w oil cooler on a ls7? Will the starter spin w plugs out fast enough not seeing pressure? only getting oil out pushrods w oil pump plug hooked up to primer, nervous to start fresh rebuild, thx
If you have oil coming out of all the pushrods, that is an indicator that you've got it pretty well primed. In some cases, you can bump the engine over a few times or hand turn the crank to make sure everything is getting a good coating. Also make sure to check the oil level in your dry sump tank after it has warmed up!
I purchased an engine oil accumulator to push oil into the oil passages and never deal w/ a dry start of my precious Corvair engine, as I like to run solid lifters w/ an oil bleed drilled into the lifter body for direct lubrication of those lifters at the cam contact point. It was a bit pricey (~$400 for the accumulator and associated solenoid to actuate the unit), but well worth the peace of mind I have every time I cold start that engine, as well as a safety for oil pressure loss at speed.
But I don’t have my engine on a stand, it’s in the truck. How tf do I prime the oil pump when I can’t get to the plug?? I’ve watched every video and all of them are on stands
I recently rebuilt my 5.3 and just yesterday i primed it by putting oil in the oil pump via galley plug on the side of engine and rotating the engine with the starter and spark plugs OFF I eventually got oil pressure after but i got a reading of 22-24 psi on the dash. Is that normal.? Or did i do something wrong?
Honestly, I stripped out one of the torx bolts on the melling hv pump. Wanted to perfectly center it, but wasn't able to do so. Managed to prime the pump at least. After about half a year, it's still holding up ok without any signs of failing. For any others out there, you may be fine without centering your pump to such parameters.
It's ok, I've been running it without having the pump centered the 'proper' way. It's working just fine for over half a year with great oil pressure. Should be ok for others that attempt this as well.
@@shadowopsairman1583 If I were to open it, that would be ideal. I never was able to open it to find true center and installed it. It's been over a year now and it's still fine. I here from others that Melling no longer says it's necessary too. Had a friend of mine just install one on his with great success as well.
Great information but how about showing exactly where this port is on the block so we can actually use the info effectively? Or explain it in more detail. Its a threaded port once you remove the bolt or whatever it is thats filling it in the meantime. Is it a grub screw, a hex head bolt , etc.
We've been through 4 or 5 different setups. This current one is probably the best so far without having to break out a lot of money for a fancy schmancy mic setup.
The crankshaft is biasing in an orbit around true centerline due to engine harmonics by more than .001. Engine startup vs cold shutdown moves crank centerline by .001. The main bearings themselves wear with time and crank centerline drops by way MORE than .001. I know this because ive seen it in the transmission oil pumps which are built the same way! High mileage wear ive seen the pump bushings worn to one side by .008 or more! So screwing around with your little .0015 shims does almost nothing and is not gaining you much. Gains you nothing after 40 or 50k of engine wear.
Best way I've found is to take the old pump drive/timing gear, and hone out the I.D., so it now spins freely on the crank nose. Then drill 2 holes 180° from each other on the face of the gear end of the piece. Tap them for an M6, or 1/4-20 thread. Make a strap up with the same bolt pattern, with clearance holes for the M6 bolts. Then, in the middle, halfway between the 2 clearance holes, dill and tap for an M8 (or whatever size) thread. Thread a short bolt into that middle hole in the strap, and tighten it up using blue, 242 Loctite. Oil the inside of the pump drive, and oil the crank nose. Insert the pump drive so it can engage the oil pump, put a 3/8" drive arbor in the drill motor with the right size socket, and spin the Be-Jesus out of the pump. You now have an oil pump Primer tool that works with any wet sump LS Engine......👍👍
Your not centering anything with a shim, unless you shim the entire crank at the same time, think how gravity works, and where the crankshaft is sitting on the bottom bearing. Go ahead and grab your crank snout and pull up on it, I bet you it moves upwards, as it isn't sitting dead center of the bearing. It won't won't center until there is oil pressure, that thin film of assembly lubeisn't enough on its own to keep that heavy crank center of its bearing.
Melling recommends that you install the pump leaving the bolts loose, rotate the crank shaft 360° and then tighten the bolts.
That's because warranty is void if you remove the cover to shim. Melling didn't have the 360° spin procedure in the past. I'll shim every time regardless of warranty.
Thank you for the information you put 🤠👍

mellings put out a video saying no shimming was necessary...to basically install it loosely and rotate the engine 360 degrees, then tighten the bolts
