Episode idea: How to set up an oil pump on the block without using the Oil Pump Alignment Tool place holder for replacement. What if we're building a new engine and the pump wasn't already there? Dig this video. Very cool.
@@rkrommel2728 that information is incorrect the reason why a new oil pump is because of the little plastic bushings on the bolts. You still need to make sure on the center rotor drive that there's a little bit of clearance movement in between there it'll be about a thousands to 2000s all the way around the Hub drive off the cranks now. Slightly snug your oil pump push it to the bottom AKA towards the pan rail and when you do that go around and check all the clearances use like a little pic and a feeler gauge and make sure you're about equal all the way around on the Hub drive. After you verify that slightly snug the oil pump up a little bit more once you do that go around and check again and then torque to spec
@@vortecturbo thanks for the reply. I ended up pushing upward on the pump, snugging them down, then torquing. I haven’t had an issue so far 🤷♂️ good oil pressure.
When the Engine Control Module changes the oil pressure/volume of the pump does it just toggle between min/max or does it have variable control of the oil pressure using the oil pressure sending unit as the feedback?
Might be mischaracterizing the purpose of a variable flow pump. It’s purpose isn’t to vary the pressure, it’s purpose is to vary the flow to achieve a fixed pressure under varying conditions. These conditions include AFM actuation, oil viscosity due to temperature, and engine rpm.
@@altonb93 I have an L87 (2021) and the oil pump housing has dowel pins to the block to locate the pump body. How can there be a need for an alignment tool if there is only 1 fixed mounting position?
I have an l83 with an lt4 blower, cammed, small pulley, methanol. I make 600whp and my solenoid went bad and I’m stuck in high pressure. Truck has still seen many 140mph + pulls since then, no issues yet. Been like 8 months
sorry to be off topic but does any of you know a tool to log back into an instagram account?? I somehow lost the account password. I would love any tips you can give me.
On the solenoid that is pcm controlled, does the pcm supply the ground side? And is the solenoid a 12V or 5V power in? Trying to see if I can setup this feature using an LS TermX on a gen5 I’m building with port injection.
If the solenoid breaks you’ll get a permanent p06DD code and on and off check engine light. Oil pressure in normal range in cluster. GMC dealership recommended replacing ($2200) it stating long term use with a broken solenoid can damage the engine.... is this true??
Nice Video Next up is the limitations of the fueling system. There isn’t a good video out there covering it. - What are the Hap limitations of the LT1 and LT4 fueling systems? - What should be upgraded first....LT1 HPFP to LT4, Injectors, low side? Etc.
Thanks Kyle, very good point. That's something we were discussing around the "water cooler" the other day. We will be getting to that soon especially with more of the GenV LT engines showing up in salvage yards as fresh take-outs. There's a lot of homework involved and you have to plan in advance. The C7 that currently holds the standing mile record pushed their DI system to the very raw edge and the HPFP had trouble keeping up with the injector demand, that record was set back when secondary port systems were just barely being tested by other manufacturers. We'll get some good data and work up a video on that as it is an important one! Thanks!
It would be best to add port injection it will be significantly more affordable versus buying 60 over D.I injectors and it will help eliminate the carbon coating from just air entering the intake port. Terminator X . haltech would be a great way to go using too high a PSI Port plates. Dial in the di to 70% fueling then supplement the additional needed fueling with the port injection. Added benefits of that it will keep the intake Runners clean. As well as cool the inlet charge if you're in a forced induction application. Plus if you decide to utilize E85 you will not be limited by the Di system. But, you will definitely have to do a low side fueling system to supply they did additional needed fuel for the high side di pressure pump as well as the port injection
So from what I’ve read the l83/86 truck oil pumps are higher volume than the lt1/4 pumps in psi. But what gets me is that Katech sells their upgraded pump for the l83/lt1 as the same pump. So is there a difference in the l83 pump vs the lt1/4 pump? And can the lt1/4 pump be utilized in a l83 truck application as I’m looking at a lt1/4 pump from Schumann pro that’s $200 less than the Katech pump. Anyone looked into this at all?
Katech sells two different pumps for the wet sump Gen V LT. A7503 is for the L83 and L86, and a higher volume and pressure than A7502 (the one for the LT1/LT2/LT4). The L83/L86 pump can be used in the LTx engines but will require some recalibration. We don't have any input on the Schumann units.
They got picky about the oil squirters because the gen 4 was plagued with oil consumption issues due to over cooling of the piston and oil rings. The low tension rings would over cool thereby reducing the effectiveness of the oil rings.
But I thought only the LS9/LSA had piston oil squirters in the GEN IV engines? Or is that what you are saying? I think the internet seems to think the LS3 and the truck GEN IV motors had excessive oil consumption issues as well, and 50 different people on the internet will claim they have the key why.
Very highly doubt it but why the hell would you want to? Either port a stock oil pump or buy a melling high pressure high volume and delete the relief valve in the oil Pan.
How I blew my motor. Failed and motor only ran for 15 seconds. Replaced with a Billet pump but one of the bearings must have been bad from the 15 seconds at idle.
Corvette 2014 with automatic transmission the customer complaint was low oil pressure and there was a noise in engine be over all the engine and restart the vehicle call pressure was showing showing normal but later on after getting a normal temperature on the vehicle Oil pressure start dropping I checked with the scan to know DTS. the oil pressure shows on the scale to60 K PA can you help meCan you help me out to solve this problem
Who can modify the stock computer in my 2001 Chevy suburban I'm putting a 408 LS that's a lq4 6 L board and stroke to 408 cubic inches I need to upgrade the computer for the new engine who do I send the computer to do you guys do that kind of work
Has there been anyone on here crafty enough to replace the solenoid with only removing the timing cover & NOT dropping the pan? I know all the books say to replace the whole unit, I'm just trying to replace what's failed without 10 extra hours of labor...
My pump has failed 3 times in the first 25,000 kms. GM doesn’t know why. I have to trade my truck in because of this before my warranty runs out. Oil pressure drops to zero.
I'm sorry but more Tech features more this and that I love you guys I've used y'all for years and years been very happy with the parts I've bought from you all but this new style oil pump with a vein is crap. It's just more stuff to fail. Why reinvent the wheel when everything is worked so well and the percentage of drag is so insignificant you will not see a measurable gain on the road with this type of oil pump.
@@Jommybutler1234 can send you a picture of proof. Have a l83 that failed this way, they designed the ring too thin around the pin that the vanes sling outward to.
@@erickindley835Your singular event does not prove causation. How many miles were on the vehicle? Had the oil pump ever been removed and reinstalled? Send a link to your photo. I’m interested to see it.
@@Jommybutler1234 singular report lmao. Gimme an email and I'll send you a pic of the factory oil pump that expired.I bought it locked up from the salvage yard for 200 bucks.

If its a new oil pump you can put it on and just center it on the bolts. Alignment isn’t necessary on a new pump
@@altonb93 why is that? Different design?

From what I've heard is that it's not necessary to use the alignment tool when replacing these. Just bolt it up and go. Is this true?
Alignment tool is required. Buy once, cry once.
Its not necessary. I worked at a Cadillac dealership and it doesn’t tell you to align a new pump, only on a used pump that has been taken off👍🏻
@@altonb93 I have an L87 (2021) and the oil pump housing has dowel pins to the block to locate the pump body. How can there be a need for an alignment tool if there is only 1 fixed mounting position?
How about alignment, adjustment and installation of this Gen V pump.

if you was telling the truth youd have bypassed that solenoid already
Thank you so much for helpful information
Good explanation...no need to go to external will delete solenoid like default to high pressure
So you just wont plug the solonoid in? It is safe to run it like that?
Do you know if I can put this in a dry sump engine to convert it to a wet sump? or would more be involved

This is in the works, great recommendation!

@Apollo Eli Instablaster ;)
So how can we put it in the fault mode to operate in a correct manner all the time???
On the solenoid that is pcm controlled, does the pcm supply the ground side? And is the solenoid a 12V or 5V power in?
Trying to see if I can setup this feature using an LS TermX on a gen5 I’m building with port injection.
Hey, I’m also attempting a similar swap, have any advice or tips? What did you do for the pump?
Episode idea: gen v torque management and how/if it hinders performance after hopping up the power. If so, what can be done to mitigate this.
If the solenoid breaks you’ll get a permanent p06DD code and on and off check engine light. Oil pressure in normal range in cluster.
GMC dealership recommended replacing ($2200) it stating long term use with a broken solenoid can damage the engine.... is this true??
What did you eventually find out about this?
