L87 Failure - Taking formal action
looks like the test showed aluminum and iron... could be a main or rod and a crank. i do not like the pico test... at 2,000 rpm.. lots of oil pressure. this would reduce any knock that this might find. it is totally bogus. you really need to run the engine up and down in rpm looking for...- PPK_

2025 GMC Yukon Elevation Paint defects?
Theses are just some iphone photos of my 2024 yukon and ‘22 f150. The f150 lariat 502 on the right really looks bad.. because the hood was pitched on as the assembly plant kept on going. Not just the looking bad.. but the window was also 1/2” high on the drivers side.. on and on.. i agree my... -
UOA and Filter photos of L87 time bomb.
I agree.. let it go.. another option is to warranty it to 80k or so with the gm warranty. I did warranty both my yukon ‘24 and slt truck to 7 yrs and 72k.- PPK_

UOA and Filter photos of L87 time bomb.
I am not sure why the gm pico test is at 2k rpm. I think you should look at idle, 2k and then run it up and down in rpm looking for some clearance… i am an engineer.. what do i know? At 2k rpm.. oil pressure is high. You won’t find much clearance issues.. I had a vibration sensor on my 5.3...- PPK_

Updated Gas vs Diesel Engine and Resale Value?
I have a 3.0 in my ‘25 truck.. and i have a ‘24 yukon with 5.3 Just filled up the lz0 in nm three or four times.. 5.50 a gallon. And then you add DEF. This lz0 is from a bmw design.. n58. All the chains and belts are in the back of the motor.. The real benefit is the turbo which really helps...- PPK_

LZ0 Article & Video - Durability Issues
Those are oil drains.. bucket emptied with syphon hose so you can see what is in the bottom of the bucket. Left side… you can see where the drain put a lot at the wall of the bucket.. and then as the pan emptied.. you can see all the debris right back to right under the drain. The 5.3 took three...- PPK_

LZ0 Article & Video - Durability Issues
I am not fan of oil burners… at the end of the day the lz0 is a 5 year 100k warranty versus the gasser’s 5 yr 60k. You have to go diesel… Digging deeper… left 1044.jpg is a 5.3 with 700 miles and the other one is an lz0 1k miles. Look at them. Up close. You will see the 5.3 has a lot of...- PPK_

Looking to purchase a GMEPP
good deal! you know if you knew a carbyte, a cache can and a 5w30 would work... you would not need a warranty. on the other hand an engine or tranny is a fortune... and a 100k cost auto is not one you trade-in when it need tires either. i did 72/72 on my yukon and truck. 84 is great. one...- PPK_

AFM DFM Conundrum
better than doing nothing. however.. it does allow the 5.3 to use DFM during coasting. bummer. i use carbyte. it works on deceleration too. and you can use 10th gear. while you are working this... do implement a wash of the intakes with solvent... as the intake cokes up with what comes in from...- PPK_
