VVT Replacement Solenoid

[thompsoj22]

Difference in quality of VVT solenoid. 08 yukon denali xl-1500 6.2 140,000 miles. Im replacing the water pump and radiator. wanted to do the VVT solenoid and cam position sensor. ordered all AC DELCO OEM parts but im having a hard time accepting the quality of the delco replacement solenoid #12653140 which replaces the OE 12585995. have any of you had success with the new replacement solenoid? i wish i could get my pic's to load but that is another challenge. The design of the replacement solenoid is a stamped "cheap" flange that does not match the quality of the original. It isnt broke, should i simply reinstall the oe and continue to run it?

I wouldn’t hesitate to put the new one in, but the one on my 2007 went 270K miles with no issues.

thanks for the reply/opinion. Im on the fence, there was no specific reason to change it other than the water pump is off and im just trying to pamper this vehicle that we love sooooo much! But there is such a thing as "fix it til it breaks". Im in the process of trying to remove the cam position sensor, yea it has varnished up/expanded and wont pull through the cover. I got some carb cleaner and will spray it to help disolve the buildup and hopefully get it to come out. than the pump can go on and i can finish this project up.

Sometimes the oe stuff is built better in my opinion, as years go by they try to save a few penny's anyway they can, on the other hand sometimes stuff is made better later usually the latter though.
this one on ebay is stamped with the oe number

that one is the ACdelco oe replacement, that is the one i got from rock auto. the oe is 12585995, 12654140 is the replacement. i guess ill simply install the new one and roll the dice. i did finally get the cam position sensor out, it was no fun. I love this vehicle so i have simply accepted the "slight rumble/stumble idle" as inherent to the 6.2 but maybe the vvt is a contributing factor so ill throw the sensors at it and see if it smooths out. im going to have my 9 yo daughter teach me how to upload pic's which make all posts so much more informative. i have all the pic,s in my phone and the computer says there are no new pictures to upload????????????????????ARGH

Can’t you upload them direct from your phone? That’s usually what I do.

aah I didn't catch ebay switching the numbers up on me.
my 6.2l doesn't stumble at idle, purrs like a kitten, maybe the intake needs to be cleaned up? I clean mine about every 3 months or so, speaking of which I am about due to clean it

My 6.2 doesn't stumble either

My 6.2 doesn't stumble either

i have read numerous posts in regard to "rough idle" on the 6.2 and accepted it as inherent. It isnt as though the car shakes and people who have ridden in it have ever noticed it but it is there. Our 09 government work van has the 6.0 with 9k miles on it and does the same thing. it spends alot of time idleing as we use it to wait on inbound helos with the ac running. so your 6.2 when idleing has "no" noticeable roughness at idle? other than the sound you cant "feel" the engine running? "smooth as glass"? Im replacing upstream o2 sensors, cps,vvt now and maybe ill do maf,map and throttle body in the near future.

I don't notice any shake/roughness
