I marked up the Khols lot pretty good. :LOL: That's pretty awesome for an open diff!

Also, I came home from Iceland to a new package. I'm trying not to get too excited about it because I know I'm not installing it for at least another year. I found somebody selling an unused ST5 cam on ebay. I shot them an offer and ended up saving about $75 over ZZP's price. (y) They packaged it very nicely too so I'm sure it's still in great shape. I guess I'll slowly start working on gathering things like even stiffer valve springs, lifters, push rods, gaskets, ect.

I was offered a day of lift use from a friend of a friend, so I took it.

We got the transmission all the way out only to find that the rear main seal wasn't leaking at all. I still had to adjust the TOB in a little though.

It didn't help the growling though, so the only thing left that makes sense is having a pissed off input shaft bearing from a misaligned bell. I'm not going down that rabbit hole right now. Growl away, I guess. 😥

After the test drive, we found that ALL the oil was coming from the turbo drain pipe. The drain plumbing needs to be completely gone through again and made with better parts. The AN fittings will not seal. I don't get why. They get tight without bottoming out.

It's hard to tell by the picture, but the whole side of the pan is oil, and the bottom is quite shiny.

This was a big waste of a day. However, I'm glad I at least had a lift to limit the project to only one day. I'll start gathering new higher quality fittings.

Ok so I thought my rear main was leaking as well because of where the drip was and hearing about the alignment tools for the cover and seal itself, turns out the end pieces on the back side of my intake were to blame. So, I learned we don't reuse those lol.

I'm starting to think that my aluminum tube is the bigger problem. Perhaps the tube flaring die I used was for 37 degree stuff while the fitting was for 45 or vise versa? It's hard to tell with the naked eye, but I think it's time to give up on the tube and try something else. It's clearly not working.

In the mean time, I have a couple new hose fittings on the way to replace the Summit junk. I'm normally a fan of Summit branded stuff, but their fittings have given me a lot of trouble. I think swapping one of my straights for a 30 degree elbow will greatly improve the slope anyhow.

ive only ever had to use braidedd hose -10

though ive always had em mounted far enough above the pan

have you verified that your not overpressurizing with oil and sending it out the turbine shaft seal?

+1 for the oil fill sensor hole lol.

The thing I don't like about a valve cover return is you don't have the gravity to help with flow but if I'm getting away with 2 90s and a line that's basically on no slope at all it's gotta be in the fitting.

I wonder if you could fit an oring in the top of your fitting to make it work in the meantime?

you have a sleeve inside the line nut? there's almost always a collar to support the flare and the nut thrust face.

oil fitting near pan flange, preferably near a main web/timing area below and behind the windage tray perimeter to keep the tornado from affecting it.

Problem I had with -10 AN is that the hole size in the fittings is nowhere near as large as it should be. -10AN should be 5/8" in diameter but all of the fittings I found were 1/2" ID
factory oil flange for the Holset I used to have was more like 3/4" ID so I just ran a rubber hose on mine since I couldn't get an AN fitting large enough or didn't want to pay as much as they costed, I can't remember

I think you're on the right track looking at the angle/type of fitting. I've heard of people having trouble with some fittings and some hoses not playing well together.

My drain hose is a -10 rubber hose, but it goes to a -12 exducer where an aluminum tube takes it from the front of the accessories to the top of the the pan. I wanted this to be more rigid because the long hose I was running before would bounce up and hit my accessory belt. It was almost worn through by the time I took it out. I have a -12 Summit weld fitting migged close to the pan rail but on the opposite side of tornado valley. The turbo actually seems to be holding up great. My charge pipe is dry, and I haven't noticed any nastiness from the exhaust.

Yes, I'm using Fragola stuff there. One thing that I wonder is what angle the automotive fitting manufacturers machine their flare angles. It's kind of important to know and nobody advertises it. To be honest, I don't recall to which angle I flared my tube either, but the aluminum is so soft that I should be able to crank it down and force it into shape.
1638880037983.png


I decided to cancel my original Summit order, do away with everything, order all new supplies, and start over. I wonder more about the flare angles now because it seems that both leaks are coming from each end of the tube. While I think the tube had potential to work with better execution, it's neither here nor there now. I decided to play Fragola's game, and order all -10 stuff of the same series. Their 6000 stuff is way overkill for an oil drain, but I wanted stainless braiding for added protection from the belt. While this will for sure be too stiff to ever bounce around, a Nylon braided hose might be just soft enough to get tangled.

I will have to run -10 to -12 exducer in order to connect to the pan, but this may be a blessing in disguise. It's possible that the Summit weld fitting is junk too. I could have warped it enough to leak since my welding is sketchy at best. It may also have been crappy from the start. If I get this all together and still have a leak between the exducer and the pan, I will have no problem scumming.... I mean skimming the Summit flange surface with red RTV and calling it a day. I tend to scoff at these practices, but it's no harm/no foul if I have another serviceable fitting right next to it. There's no way in hell that I'm pulling the pan off just to replace the weld fitting.

I've also redone this enough times to justify trying a fancy 30 degree elbow out of the turbo fitting. 45 is too much and straight down doesn't make sense either. By the way, there is a small victory in all this. Two fittings and some timely custom work later, my turbo drain flange fitting finally stopped leaking! 🥳

Off I forgot you were ran into the pan 🤦I was gonna say I just ziptied to a power steering line to stay out of the belt but where your on the other side I don't think there's much over there to do that with. Glad you got it fixed!

I am not sure that the elbow angles I chose are going to be the best options due to their longer sweep. 45 and 120 may have been better, but I'll find out for sure tonight. The satisfying part is that a little extra money went a long way. Don't screw with the Summit branded fittings. They're a PITA on so many levels. I did a lot of cussing when I was building my catch can hoses. Sure, they sealed eventually and turned out alright, but it took a lot of WD-40 and elbow grease. I still cuss at them now because their hex size does not correspond to their fitting size. In other words, my fancy aluminum AN wrench set is useless on some of my Summit fittings, and they're slowly turning to shit due to using adjustable steel wrenches on them.

Fragola hose ends though... 👌 These things are a breeze to put together. Matching Fragola hose and Earl's vise jaws got this fitting together without any muscle or WD-40. There is no spinning where things aren't supposed to spin, and I have no doubt that these hoses will be leak free. One feature I though was strange when I bought them is that everything including my straight reducer swivels. It seemed unnecessary at the time of purchase, but I totally get it now. All I need to get right is the length. There is no need to be dicking with the often time consuming process of clocking the fittings just right. Go Fragola! Even if my elbows are the wrong angle, I have no problem buying more and keeping these in my tool box.

And sizes are 5/16 of an inch OD tube diameter so I dashed n is for a 5/8 OD tube. ID tends to be smaller yes. To find out what angle it is all you need is a small inside square a 45-degree SAE flare fitting will be a 45 degree face so the right angle Square will sit across both ceiling surfaces. The a n fittings / jic 37 degrees stuff you will see

The 30 and 90 degree elbows turned out to be a great choice.

Best of all, I don't even need zipties to keep the hose away from the belt! I wish I did this from the get-go. It was much easier than I pictured, and worked flawlessly. I still haven't done enough to eliminate the smoke though. :cautious: The turbo drain doesn't leak, but it appears that the oil pan gasket was the worse offender.

Screw this thing. No, it's not getting ANOTHER new pan. No, it's not getting ANOTHER new gasket. This sloppy whore is getting the smear of RTV it deserves. I'm also going to remove the wrap on the bottom of the crossover, since it just seems to soak the oil in and exacerbate the problem.

Oh my god... That's a huge pipe... How on earth is this supposed to fit?! 😯😍🍆💦
PXL_20211222_204910344.jpg

Even more obnoxiously BIG things are on the way. ;)

Okay, this porno's over!

Two things I dislike: tater pipes and single turbo cars with dual exhaust.
This is the only single shot I could find that cost less than a grand. It's aluminized steel and 4" in diameter. Yes it's way overkill. You can call it a bro dozer if you like, but it achieves my sleeper look (turn down before the bumper) and it's cheap ($500 after shipping and tax). Thanks, Hawks!

Here's a first. I bought a non-engine F-body part for an LS car that didn't fit my V6 car. It took a lot of dicking around with the hangers and surfing the internet to learn that V6 and V8 F-bodies got different exhaust hangers and brackets. Weird. My hangers were rusty as hell anyway. Shocker! I guess I get to do some shopping. Anybody parting out a 4th gen?

Even after that, I'm not convinced that the pipe is going to fit between the floor and the track bars. I have seen more people say that it fits great than those who don't though, so we'll see.

My hangers. Looks like my driver side hanger can just be cut to match the LS style.

I'll have to look at my bird when I get some time if i didn't cut them up. I'm not sure if they'd work from a y87 car tho didn't they get the same exhaust as the ls cars?

They don't make repops yet?
It looks like Walker makes the passenger side. The driver side is all steel. Since mine aren't bad and I have the rustiest running F-body on the planet, I'd say it's probably not necessary to repop them. :LOL:

Not sure about the fancy V6 cars but my ultra basic car had a 2.5ish inch single. I think LS cars have a 2 3/4 inch ish fake duals.

Siiiick. An old homie from school who's an F-body fanatic is sending me and LS hanger. There is a repop for third gens but not fourth gens. Apparently they're similar, but the third gen piece needs a little work to fit in the fourth gen. Oh well.

The fancy v6 cars were a 2.5 or so to a single muffler with fake duals, limited slip rear end and steering box from the v8 cars, might be a couple other insignificant things but that's the gist of it.

Rear ends were the only thing I really cared about even tho they still kinda suck
