Still chasing an oil leak that is getting worse by the day, so I replaced the crankshaft position sensor as the starter was wet. I don't have high hopes for it. Already did the pan gasket and pressure sensor. Next up is valley cover gasket and if that ain't it I'm afraid the rear main is the culprit.

Might get one of those scope cameras and stick it in the bell housing because just eyeballing it with the cover off, I can't really tell anything.

How do you diagnose that lol I would absolutely prefer it to be the heat shield

Last time I had a noise like that, it was on my Ram. I chased down the issue by climbing under it with it turned off, and just bumping it with my palm at all different places on the exhaust system. Eventually, you'll hear where the metal is clanging together. Beat it as hard as you need to to make it rattle... then just follow the sound.

Mine turned out to be a loose exhaust clamp, but heat shields are the most common problem.

I contacted a company close to Paris, which reprogrammed the PCM to run on ethanol. They take $ 785 with benchmarking and performance optimization.

By cons they keep the car 4-5 days because they have never worked on the 5.3 Vortec.

I am waiting to finalize the sale of my old vehicle and forward ...

Return them and get the Bilstein shocks you won’t regret it, they are about the same size as the autoride shocks front and rear

I need to do this. My RPO codes are:
[emoji3502]6XK - Spring comptr select frt lh
[emoji3502]7XK - component frt rh computer sel susp (7XK)
[emoji3502]G65 - Level Control man, self-adjusting
[emoji3502]YD6 - spring, rear (base equipment)
[emoji3502]ZW7 - chassis package, premium smooth ride

I believe this is just the self leveling shocks.. not sure if they have a sensor or not. I do not have the air pump.
Wanting Bilsteins but after reading a lot about this, I’m still not sure what I need, and if I need replacement springs as well.

Are you staying stock height? The Bilstein yellow and blues which are the 4600 are a great stock replacement shock I run them on the Escalade rides pretty good for being lowered out back I’ve got shock extenders up front I should have went with shocks for a 2” drop because there isn’t a lot of travel left in them but aslong as you watch how you drive you’ll be fine and I replaced the springs because I wanted to lower the truck

Bilstein 4600 or 5100 depending on your plans. You will need new springs either way because of your zw7.

Planning to just keep stock height. Although, I wouldn’t mind getting the front and rear closer to level. I guess that would mean either some height in the front, or a bit of drop in the rear. I figured bilsteins because they have a great rep around here.

Thanks for the note. So I’ll need springs front and rear? I have no idea what I’m doing obviously. I believe the 5100 will be to keep stock height? Would I use 5100’s for both front and rear?

If you want to lower the rear to match the front they make kits with a 2” rear lowering spring & shock adjusters that would work perfectly

Only springs in the rear on the NBS trucks
