    Thoughts on AFM Delete

    Absolutely! Hoping to not go that far in the motor just yet. My hopes is we can do the valve cover, vlom and filter, oil pan deflector and I even went as far as saying new oil pump and oring while im in there. It would really suck to do this work only for a lifter to fail anyhow. Will see the...

    Thoughts on AFM Delete

    I do not have a tech 2 but I think my cousins snap on will work the solenoids. I have done a fair share of research on upgrades to keep AFM and the vlom was one thing I found to be a issue as well as the oil pressure filter under sensor. I have kept a close eye on his pressure and it seems to be...

    Thoughts on AFM Delete

    Buddy just purchased a 2009 chevy silverado for 1500 bucks with 180k. He works for culligan water and the truck was a company vehicle. 5.3 rwd, a little rust as we are in PA but overall a solid truck and runs fairly smooth. The first time he drove it home before buying I looked it over and...

    Pacesetter Headers

    I have a manifold leak on my drivers side and when thinking about replacing I get the thoughts of putting headers on. My truck has over 300k on engine but was partially rebuilt a year ago to remove AFM, it doesn't have a performance cam or anything but does have MBRP exhaust and K&N cold air...

    Aftermarket radio RAP function not working

    Purchased pioneer H/U and PAC RP5-GM31 for my 2007 GMC Yukon xl and everything works besides the radio turning off when i open door. My factory radio still operates that way but I have tried two PAC harnesses with no solution. I do not want to run any extra wires to get it to turn off with key i...

    Rear end parts identification

    shimmed it up and got it to .006, was a fight getting it all in evenly but I got it. It’s all tightened up now and just needs a test drive. Thanks for all your help. I usually use analog when working on the vehicles as I like to get my digital sets in the machine shop. My home micrometers locked...

    Rear end parts identification

    Is this something that should be changed while I’m in there? If so do you guys know how to remove it? Slide hammer? Or should I be using a long pipe and knocking it towards center of rear to get out?

    Rear end parts identification

    This whole rear has been interesting. I know nothing about rears but learning a lot right now. I’m in this position because the ring gear bolts all sheared off. Lol. Don’t ask me how, I’ve only owned and drove the truck for a few months after I did a afm delete. All gears looked perfect so...

    Rear end parts identification

    I have my rear apart trying to do bearings and seals. I have the parts on hand ready to install but can’t seem to figure out what this part is. I would like to replace it while I’m in here but can’t find any info on what it’s called or anything online that even looks like it for me to find a...

    P0430 cats and o2 sensors all replaced

    2007 Yukon xl P0430 Got this code after motor rebuild afm deleted and chasing down a few o2/ misfire codes once all was done. Truck seems to drive fine I’ve put over 1000 miles on it since rebuild. My scan tool shows a really low count of misfires from time to time on a cylinder or 2 but it...

    Figured I’d post this pic of cam bearing, maybe someone with some experience with these motors could say what condition it’s looks like. I’ve found on other forums this isn’t something to go crazy over so I didnt worry. Tell me what your thoughts are.

    2007 GMC Yukon XL

    Here’s a few photos to show the progress on my 2007 xl lc9 AFM delete. I am hoping to have it back together by Sunday before the weather gets crappy here in Pittsburgh,PA. All parts are GM factory components and things I have replaced are oil pump, cam gear crank gear and timing chain assembly...

    2007 GMC Yukon XL

    Haven't had much time to work on the xl but will try to get the pass side head off today and remove pulley to get front cover off. Have been doing steady research on which repair procedure and i think im leaning towards the DELETE kit. would rather not have issues down the road as i am still...

    2007 GMC Yukon XL

    Thanks buddy. I should have diagnosed a little further as I saw my number 7 plug was not all the way in the block, which I think would cause misfires, but not bend a push rod? So it’s nice I tore it down anyway as I would have never diagnosed that bent rod. Just weird everything else looks good...

    2007 GMC Yukon XL

    I have got the driver side head off the truck today and found a bent push rod on cylinder 7. The rollers on the lifters are smooth and have no pitting or signs of damage. Have to go back tomorrow and get pics of lifters as I’m not sure what they look like when collapsed. Piston also showed no...

    2007 GMC Yukon XL

    I have been on the forum for over a month now and have seen you speak on this on almost every related post. So I’ll ask you, has the gm tsb actually fixed the issue? Tons of info on the delete and a lot of happy owners once done but not that many people talking about the problem being resolved...

    2007 GMC Yukon XL

    Not 100% sure about coil or injector. I did replace plugs and wires but didn’t get around to checking coil or injector, I know I should have but I let the internet persuade me into just pulling it apart after seeing so many of these lifters failing. Kind of flabbergasted when i pulled valve...
