    2013 Yukon Denali 6.2 lifter problem and cost??

    Your $4000 quote is reasonable for sure... IF you are just doing lifters and the cam is still fine, then my advice to You: Replace the VLOM with the new updated part from Dorman or get the GM part. After all the work is done, TURN OFF that damned DOD/AFM... There are a few options to turn it off

    Misfire on cylinder 6 after cam and lifter install

    YES they did. It's a new part #. I used one on a 2009 chevy 5.3 couple of months ago

    2010 ESV tranny issues

    After re reading.. it looks like your issue may have a little bit to do with colder cooler ambient temps.... Which to me signals a LEAN condition. You should look at your LTFT for both banks and see what they report. It might also be time for new upstream Oxygen sensors. They are a wear part...

    2010 ESV tranny issues

    On the 2010 model I'm not exactly sure what the fuel pressure should be, but on the 12-14 it's should be in the mid 50's for sure. 42-45 seems low to me

    Delayed shifting after throttle body cleaning

    After reading the latest comments, I would remove the TB and clean both sides of it. Reinstall it with a NEW gasket/seal... Then do your idle relearn procedure yourself. You 'may' want to recheck or reclean your MAF sensor too.. Just to make sure. That can cause funky behavior too

    Misfire on cylinder 6 after cam and lifter install

    Just wanted to add: the Dorman company has an "updated Vlom" ... it is an improvement from the OE vlom and from their original replacement vlom. It's prob the only one i'd use. (now other dorman stuff "can" suck)

    Delayed shifting after throttle body cleaning

    After cleaning the TB you will want to do an idle RELEARN procedure. You can do it with a diagnostic scanner or even without one. Just search it on the web for GM DBW throttle relearn

    Aluminum Block Oil Pressure Loss

    I would imagine that "billet" vs "cast" alum blocks may make some difference here. And of course the make up of the crank itself - steel, forged, billet... The crank would expand "some" with heat to close the clearance a bit I think this is the reason (maybe) that gm has gone with a variable...

    Uneven Idle is getting progressively worse but cannot find the cause (Fuel Pump / Injectors?)

    It will idle better with the 91 octane (on the 6.2L). The reason is that it goes to the HIGH octane tables on the spark tables As soon as it detects "knock" it will then go to the low octane tables. The difference in timing is subtle at some points, but around the idle area it's about 2-3...

    Help needed with P0171 & P0174 running lean at idle. My fault!

    The intake removal job is pretty easy. There is no coolant in it.. That's why I don't really understand the importance of doing the oil pressure sensor job without pulling the intake as it's really easy.. Just my opinion... The fitting on the back of intake to the brake booster is a swivel type...

    L94 to L96 engine swap

    To add: IDK if the 6.0 has cathedral port heads or square port (like L92-L94-LS3) This "may" affect your exhaust manifolds, not sure And of course you'll have to use the intake etc off the 6.0 if it's cathedral port heads

    L94 to L96 engine swap

    They should both be 58X crank teeth... You'll want to be sure you get a GEN 4 not a Gen 3 if you are doing a complete swap. You will also need to get a "tune"... As the 6.0 is not E85 compatible and will have a diff camshaft, injectors, etc than your FlexFuel 6.2 L. the compression is...

    Help needed with P0171 & P0174 running lean at idle. My fault!

    It would have been almost impossible to knock the VLOM plug loose -its your first picture, although that WOULD cause a check engine light. The other two are a good possibility - the one at the rear of the intake to your brake booster is a big one- you'll have to remove the intake manifold...

    Help needed with P0171 & P0174 running lean at idle. My fault!

    Agree with rocket man.... You may have inadvertently touched a vacuum/ air line that was already in a deteriorated condition That's a pretty big air leak for the FTtrims to go to 25* quickly Triple check all that good stuff

    Regearing Question

    No matter what, you will lose MPG with a bigger/heavier tire.. The gear ratio change to 4.10 will just make up for the taller tire Your performance should be similar to the 3.42 w 31" tire, other than you are having to spin more weight- lots more You will still want to "tune" your PCM for the...

    proactive instead of reactive - another AFM delete

    My lifters I used were cam motion brand. I bought my cam and lifters from Gwatney Performance.. OF course that was a year ago this week. SO I don't know what they have now.. They are a GM Dealer so you can get GM OE parts too

    proactive instead of reactive - another AFM delete

    Just to add to swathdiver's info: DO NOT BUY parts like these from places like amazon and ebay... You WILL be sorry, no matter the savings. There are TONS of knock off parts going around. A lifter is not one of those you want to take any chances on. It'll wipe your motor Use summit racing...

    Input or advice from others on cam swap for 6.2L 2011 Yukon Denali

    I did quite a bit of research (not real world testing like Geotrash) and decided to keep VVT. I didn't have to replace the timing cover, etc which was a bonus... From what I've seen, it does help with torque and will help a little with gas mileage in the midrange. Remember, that VVT in...

    I've developed a misfire, and I could use a hand....

    Well , you said "COIL" .. you have 8 of them and they fail very rarely... But with the stuff you've done, I'd suspect maybe some torque converter shudder maybe, although less common on the 4L80E... or Even Spark Plugs Still... Use AC Delcos from a reputable source... Lots of fake parts out...

    Useless Information

    That is why I could not use E85 with my Edelbrock SC.. Not enough fuel.. It uses the stock Flex fuel pump and injectors, so that pretty well maxes them out. It didn't affect me much since E85 isn't the norm around here

    Useless Information

    When my Yukon was bone stock, I did some 'science' on the E85.. I didn't notice any difference at all in power or performance... The only thing I really noticed was that my HWY MPG went from 16/17 ish to about 14 ish on a good interstate trip. The trade off for price per gallon seemed to...

    Input or advice from others on cam swap for 6.2L 2011 Yukon Denali

    218/230 116+4 .586''/.586'' Lift with 1.7 This cam is way too big for our heavy trucks. Yes, with a supercharger on it, it would be fine. But getting it idle and behave would be very time consuming... WITH a supercharger, you DON'T need a crap load of cam... Unless it's a race...

    Adding Factory Style Auxiliary Trans Cooler Lines - Tru Cool 40K Install

    If you want to use factory type lines, then install a factory AUX Cooler.. That's the best advice I can give. If you want or need an oem cooler you can message me. I removed mine at low mileage to put in a HD fan cooled aux cooler due to my HP and towing needs

    Rough idle, lots of vibration, sluggish acceleration, shuddering at low speed

    Without any codes present or even more info like a scan tool log file, it would be unwise to buy a set of injectors.. And I wouldn't buy them from amazon- lots of fake imposter parts there. You need to buy parts from a "non third party seller" like summit racing or rockauto . Lots of "brand...
