Going to try to get under the 07 after work and clean up the oil leak and pinpoint its source. Do we think it'll be the rear main, the oil pan gasket or the oil cooler block off?

Given my personal experience, it will be the pan gasket... :(

PS - Although I think that is better news than the rear seal. So...

I have done the oil pan gasket. Are you 2wd or 4? It’s not a bad job with a lift. Not sure if I would be excited to do it on some jack stands but it wouldn’t be horrible. 4wd requires removing the front diff. Also don’t over tighten the rear bolts that go into the rear main seal back plate. If you over tighten them you’ll create a leak.

Lol, just messing with you--at least you didn't freak out!
Nah. I know what it has. There is a light scratch from a damn microfiber towel. They’re billets, it’s part of owning them. They had some pretty good ones just from washing them last summer and I bought a big DeWalt 1/2” polisher. That thing polishes them until they’re mirrors. But to do it right I have to pull them. The centers are brushed and clear coated so they just get wiped off.

I remember you paying huge $$ for them.

My sentiments exactly. I'd be ok if it's the pan and the oil cooler block off as long as it isn't the rear main seal. The truck is 2wd, so the pan would be pretty straight forward, even in the driveway.

Not too bad, like $6k for all 4. :chair:Then there’s $4k in Wilwoods behind them. :insane:

Yeah, Billets cost money for sure. Then tires are additional expense...

I used to roll on Intro's, I picked this set up for 500 bucks, just had 2 bent lips, had rims fixed and good as new... ahhh the old days...

That’s the cool thing about billets- they can be fixed pretty easily. intro will even re-hoop them if the hoops are too messed up as long as the center billet parts are still good.

Got the tracking number for my Stainless Works 3.5" catback. Should arrive Friday, too bad I'm working Saturday.

Just ordered a set of the rubber baffles that go around the radiator...might be buying a cold case sooner rather than later.

Changed the front brake pads and rotors. And found out in the process that both front caliper brackets had badly frozen caliper pins. They were solidly stuck in the caliper brackets, and wouldn't slide, or rotate, apparently.

I tried to put a little twist to the stuck lower guide pin, but it just went POP.

Luckily the parts store had new front brackets, guide pins, and boots in stock.

Then this happened....

Driver's rotor was seized on the hub. After lots of lube and heat it just came down to percussive maintenance, but once that was off I was able to brush off all the old crud and get it nice and (mostly) shiny-ish. Installation was a breeze.

I was ready for a battle on the passenger side, but everything came apart without a hassle. The passenger side caliper bracket also had a seized lower guide pin, but I had bought a new bracket out of caution, so as soon as I realized that it wasn't turning/free-moving I chucked it in the ****-It Bucket™, and carried on. Driver's side took like 2 hours including trip to parts store, passenger side took 30 mins, including beers and inner reflection.

Cleaned up, and went for a little rip to verify the front brakes worked. I'll finish up with the rears this weekend.
