They say the resistance on the VLOM should be 11 to 18 ohms. I purchased a brand new Dorman updated VLOM and the resistance is about 24 ohms for each of the inner prongs and the outer most prongs together read around 14 ohms. Is this correct?
@CrazedPerformanceRepair ok. So that will be the one under my air filter right? How long will it take to get back and will I have to do any other modifications with this?
@@sigfriedpalmunda2347 if you have a truck it's next to the unused battery tray behind the radiator. You can do just the tune if you want. It just tells the computer not to use it.
I did the delete on my 08 silverado after I freed the lifter modified the vlom gasket plugged oil hole got it all back together runs like shit no power help please
It could but its not common and you would have to be babying it. If it is partially collapsed it wont open the valve enough during heavy load and cause it to misfire. Check misfire history in the live data of a scan tool to see if it has a cylinder showing a history of misfires. Check for broken manifold bolts.
@@CrazedPerformanceRepair thank you for the response. After ordering your kit it has arrived. I have both valve covers off and there is no play in the rockers after rotating the crank several times. I have an inexpensive scanning tool showing no codes, but the sound when running is nearly identical to the other videos online with a collapsed lifter. Is there somewhere I can borrow an advanced scanner? Where do I go from here?
My vlom was crazy loose. was able to remove all bolts with 2 fingers. wasn't able to free my #1 lifter. inspected the can shaft and it looks ok. plan to remove heads, replace all lifters and have heads resurfaced and cleaned up. changing all of my gaskets and should have a nice running engine. i will modify the vlom as instructed and plug up the oil port. the recommended programmer is a great bargain.
Changing lifters, trays and gaskets on right bank and found a few vlom bolts loose. Should I change the gasket as preventative maintenance? Any other recommendations while I'm this deep?
Man last to i did was loose i have all aluminum block 243 heads im doing now. It was barely ticking and 1 bad lifter after a atf flush no tick great oil pressure. An they insisted all new lifters both sides all new lifter i ran atf threw it no missing after that. But since i put new lifters in it it is raddling worse than it was. I tore it back down the drivers sides good i put newer 2014 n up vakve cover on that side. Now I have to go to pass side,but i noticed on lifter bore those holes are opposite. Do you think they may have spun in the block.
Thanks for all your videos, I've learned a lot. I just rebuilt a 5.3 put in new lifters, pushrods, oil pump, and VLOM. When I start up, it sounds like a sewing machine. I have 50 lbs oil pressure, and oil coming out of the rockers. Is it possible I got a bad set of lifters? One of the lifters was collapsed when I got it, I replaced it with one of the old lifters. I just wanted to know your opinion before I pulled the heads. Working outside in Western MN. Thanks
@@CrazedPerformanceRepair Yes. I had dropped a valve. bored .010. I replaced the Pistons, bearings, main, rod, and cam. The engine only had 322,000 mi. I put on some different heads with 91,000 mi
Hey hopefully you can give me some insight. Got a 2012 Silverado. Been getting p0521 and p0300. Sometimes p0305. I replaced all plugs, wires and coil on cylinder 5 and swapped injectors but no difference. Still getting a misfire. I just checked the vlom bolts up front and they were finger loose. So my question is what to do moving forward. I might replace the vlom but it’s weird I was getting a misfire code on cylinder 5 which is not one of the cylinders the vlom controls. I also did a compression and leak down test on cylinder 5 which checked out ok. Looking forward to any advice. Been chasing problems on this truck for awhile.
@@CrazedPerformanceRepair all I did with cylinder 5 injector was swap it with cylinder 3 to see if the misfire would chance and it still was at cylinder 5. I didn’t check anything else injector related.
@@CrazedPerformanceRepair the misfire I have seems to take place when I let off the gas and coast for a bit and then get back on the gas. As soon as I get back on the gas you can feel it stutter and then it’s fine.
I'll just go ahad and say it, any engine with AFM no matter what brand what year, buy the plug in AFM delete from Range Technology, plug it into you OBD port (5 seconds) and be done with that shyt. If you want a 4 banger buy a 4 banger. The 200 bucks for the RT plug is soooo worth it...Roost
@@CrazedPerformanceRepair dang man that's good info. I know lots o folks dont wanna fool with a professional tuner, this plug in thing is so user friendly. I will check that out for sure though thanks for that. I took mine to a tuner hopefully I caught it in time. Hey one way or another needs to be done, its a motor killer. Imo the upside is so not worth it, save 1-1.5 mpg but but your motor at a high risk. Not much of a decision
Hey man enjoy watching your channel the knowledge is much appriciated. I have a 2010 tahoe flex fuel and I had an oil pressure issue when warm would idle at 19lbs with faint passenger lifter tick. Found out pinched oring on pickup tube now oil pressure is where it should be. The tick now is intermittent but I was watching this video and was like hmmm I'll pop my hood and reach down and low and behold front passenger bolt loosened with fingers. If I tighten them to spec do you think tick will stop or more then likely lifters collapsed. Thanks for you channel keep it up
If this is a factory error then why has GM not recalled this the oil leak can start a fire like it did in the 2000-2005 Wbody and others with the 3800 series engine(remember they HAD 3 RECALLS for the same EXACT issue ) there has been a few fires all ready because of oil leaking burned a couple of houses down
I have a 2008 Tahoe and the vlom was loose and oil sensor filter was filthy the six cylinder is missing the lifter goes up and down when I turn on the truck but then stops and when I turn IT off it runs up and down and stops so its not colapsed.. do you think the vlom is the problem or the lifters?
Why not just use a smaller steel dowel to hit on the lifter? Also that wear on the push rods and rocker arm is from lack of oiling. I have seen it quite a few times, especially on the older Chevy engines like the 5.3l with high use. A high volume oil pump can restore oil to these parts in a worn engine.
@@CrazedPerformanceRepair man i have a question i have a 243 heads LC9. I did the atf flush it worked. I used 2 new oil filters. An tick was basically gone. Then it went away. Lifter was just stuck from grime. So the only tick was on drivers side. Then they instisied i installed all new lifters and all new head gaskets on both sides. The truck only needed 1 dod lifter at most. But i did what they asked. An i put new screen n oilsending unit In it. Now after lifter changes n head gaskets raddling worrse then it was. (Vlom was loose in front like normal) i cleaned the surface good all new head bolts. Torque all rite an i went to new valve cover for like 2014 model. Vlom gasket looked good. Any ideas. I dod notice the lifter bores oil holes were turned different directions.
Mine is still broke down in the driveway.what a system Chevrolet came up with.Mine has cylinder 4 collapsed.Have you ever just thought of just replacing all lifters and vlom and fixing back original instead of deleting.rock auto has parts for little under thousand.
I have fixed them back to normal and had it fail again shortly after. The system is better off shut off. I won't even cover warranty anymore if a customer requested I repair and leave system functioning normally they are that bad.
So basically when the engine gets lot of miles and oil pressure starts to go.the system can't function properly and just destroys lifters again and again.When I had it towed to Chevrolet.They recommended replacing all lifters and said it would cost me 5,000.So I went into shock.lol.I just can't find no one that can do a delete locally.they also said they would have to inspect the cam and if bad they could find one in junkyard for 6,500.

It's 14-17ohms from what I've seen. Why not just shut off AFM in the tune for $50 and have less problems and expense?

What should the VLOM bolts be torqued to? Also, I think some blue loc tite would also be a worth adding

no you can't drill it out there is also a lifter support in the way not just the head.

That comment did not make much sense, but I better make sure you know that there are two valves per cylinder and not just one.
Would buying a used engine out of junkyard just lead to problems again down the road?
Yes
put a Hemi engine in it from a hellcat
