I attempted this last weekend along with an oil change. Found out (and looking back I'm not sure how I missed it as it looks quite different) I have the cooler lines running in here, not just the block off plate. I was able to access this with a small ratchet and finagling my arm up in there on...
Any signs or symptoms to look out for? Im only at 104k miles. all stock. installed a catch can around 4k miles ago. very little highway. seems to run good so far.
I listened to countless youtube videos of other 6.2l. I'm a big borla fan. Had a borla catback on my ram. No drone. Sounded pissed off when you started it up. Seems that some borlas sound good and others not so much. Could be the quality. Hard to judge an exhaust on youtube. There are not many...
Maybe poor maintenance too? Pushing limits on an oil change interval is always asking for trouble. It's just not worth the risk. Either bite the bullet and change it early or do a few oil analyses to validate your longer intervals. Not all oils are created equal. Anyway....that's another subject...
Does this include the 09 denali 6 speed? If I'm really light on the throttle in the morning I can get a hard 2 to 3 shift. If I accelerate harder it shifts fine.
If so, does trans need to come out for this repair? I looked at that bulletin but I couldn't figure it out. How in-depth is diagnosis...
appreciate the info....but what is the cause? these 09s do not have active afm so the whole cam/lifter issue associate with afm shouldnt apply.....correct? is it just bad luck causing the broken valve spring?
Keep us updated if you can. Being a range of possibilities, it could be helpful to us others with this warning on dash. Funny thing with mine (09 Denali) is its not every startup. Most but not all. Both rear airbags are taught. I do believe my compressor is done as it doesnt make any noises. My...
If you dont mind me asking, what caused the destruction? My 09 denali runs great but you now have her worried. I dont recall reading a lot about engine issues with these 6.2L trucks.
I have an 09 denali. Im going to be tackling this as well. from what i gathered, the gasket is 12611384 AcDelco. Its a thin metal gasket. Not sure if it matters the orientation of the "squared side". I was going to look at the one on the truck and go from there. Im also replacing the "cap" as im...
Second this. I have had a slow leak since i bought my 09 denali. A few weeks ago i went under and wiped everything down to start chipping away at small things. I need to replace the block off plate gasket and go from there. well i went under this weekend and there was oil everywhere. My first...
If you have the time and patience look for an 09 Tahoe ltz with the 6.2l. not a lot of them out there. But a perfect combo of the 6.2 and 2wd / 4wd vs awd. I found an 09 Yukon Denali for my wife for the same reason....no afm. The awd is perfect for her. It drives great, is loaded etc. If I were...
