    Since I am still waiting on the fuel injectors to return and parts to arrive for the crank pulley, I moved on to the electrical upgrades. My plan was this: -220A alternator -1/0ga (-) battery cable with new terminal -new RVC sensor -1/0ga (+) battery cable with new terminal to the mega fuse...

    On a side note, the LS balancer/pulley tools I ordered arrived today. All are Chineseum, but will serve my needs. I did ensure the installer I ordered had a ball thrust bearing. I am going to pick up an M16 x 2.0 x 60mm socket head bolt at work tomorrow. I have seen the little thrust rods bend...

    Last thing to do for the cooling system refresh was to replace both the FAN HI and FAN LO relays in the underhood power panel. I got the old relays out and compared them to the new ones. And realized I screwed up. Old relays were 4-pin. New relays were 5-pin. OK, not a problem. 5th pin is your...

    OK, thanks for the explanations! I now understand that my confusion stems from me mistaking the crank pulley for an actual harmonic balancer. It not being keyed made me think there was a specific position the crankshaft had to be at and a specific orientation for the 'balancer' to be at. I now...

    Thanks, iamdub! I would stick with the stock tensioner then. However, to get the 5 more bolts, I have to remove the oil pan. Oil pump doesn't come out without dropping the oil pan, correct?

    OK, I am getting cold feet. I have read through various procedures in the service manual, and this is becoming a steeper and steeper slippery slope. To replace the VVT actuator (camshaft sprocket): -lower front differential -remove oil pan -remove timing cover -remove oil pump -remove timing...

    Ah. I knew there was a heater core back there. However, I thought the plastic ends of the heater hoses were molded on. I will climb under and get a better look. Thanks!

    iamdub, thanks for the info! I did not realize the VVT cam phaser was also a ‘wear’ item. Since we are looking that far in, what about: -timing set? -timing chain tensioner? (I thought I read something about there being a better option for this) Thanks! Hello j91z28d1: yeah…I tend to go...

    Alright, I'm home now, and have had access to the service manual, and the internet. Which is bad. Because I am stupid. I just put a Rock Auto order in for: balancer balancer bolt front seal serpentine belt and tensioner kit crankshaft position sensor I just put an Amazon order in for: LS...

    Hello donthejetman! OK, I am listening… Can this balancer be replaced by a home mechanic? What kind of special tools are needed? From what I understand, this balancer is not keyed. Also, the bolt is to be replaced as well? I am assuming I would replace the front main seal as well? Am not near...

    I installed a new CMP, new actuator, and new harness assembly for both. Swapping the parts was not awful, but a bit of a pain because I didn't remove the harmonic balancer. So the plug for the CMP, and the plug at the bottom of the harness was a chore to get disconnected. As well, the lower bolt...

    During the cooling system refresh, I did do some WYAIT (While You Are In There) work. I like to replace sensors and such on a preemptive basis for the most part. How difficult access is plays a part as well. For example, I will likely replace the MAF and MAP whenever they start to fail. Easy to...

    I replaced the little O-rings for the front steam bleed crossover tube. And the slit rubber hose that covers the metal line. I do not understand what that is for. I ordered that hose, as it was listed as 'bleed crossover hose' so I thought I needed it. The new one came in the GM bag slit down...

    Heater Tees off and both sets of heater core lines are bare. New Tees installed. (Yes, the wiring loom is trashed. I will be removing it and installing braided mesh loom.) New water pump and thermostat assembly. I also installed a new coolant temp sensor in the left cylinder head...

    Next goal was to refresh the cooling system. I had added radiator cleaner solution to the cooling system approximately 2 weeks and 500 miles prior to taking my Escalade off the road. I had drained the radiator back in October of 2021, approximately 29,000 miles ago, so the coolant did not look...

    You may have noticed that I did NOT install the A37 bearing plugs into the AFM lifter towers in the engine valley. I bought a bearing, and removed 8 rollers from it. I was on the fence about it, since my L94 is an aluminum block. A37 wheel bearing rollers for plugs. However...I learned a...

    The next part of the 'VLOM Mod' is a sleeve that presses into the oil pressure sending unit bore. This sleeve blocks oil pressure from flowing into the VLOM and to the solenoids. It is considered insurance against a leaking solenoid. The Black Bear tune ensures the solenoids are never energized...

    Because I can't leave well enough alone, I have answered the question nobody asked: What does a VLOM look like disassembled? I took it apart. Mainly to do some cleaning. All parts except the solenoids, electrical bridge, gasket, and the electrical connector receptacle were soaked and then...

    I am still on the fence. I have been watching youtube videos and looking at plugs from various sources. I have seen a few put steel plugs in aluminum blocks. But I have not yet fully talked myself into it. The aluminum towers look beefy. But...

    Hmmm...rereading that thread, it implies the A37 bearing rollers are for cast iron blocks, and not suitable for aluminum blocks. The L94 in my Escalade is aluminum. :confused: I might look at the DOD plugs from Texas Speed...

    Another genius idea

    Gentlemen, I know this thread has been dormant for 2-1/2 years, but I have a question. And it is stupid one: Are the A37 bearing rollers not suitable for plugs in an aluminum block? I am working on the L94 in my 2013 Escalade, and am installing the VLOM Mod from Crazy Performance Repair. I...

    I had read that in the past, and have been thinking about it. However, I am still on the fence. Because it is pretty much permanent. On the other hand, like I said above, DOD has been turned off in the tune, and I will never turn it back on. If I ever open the engine up further, I will do a full...

    I had never heard of the VLOM Mod as well. I tripped over it while searching for how to remove the intake manifold. It seems like a good idea to me. I looked at the cam lobes that were exposed in the valley. They look good to me. I will try to get better photos next time I am out there.

    These photos also go with my first post in this thread. Uh-oh... Oh-no... Grrrrr... New outer VLOM gasket GM 89017690. Rock Auto has it on closeout for $45. It is listed as 'valve cover gasket, upper.' I posted this photo because I read about numerous people having issues finding...
