I'm curious about the factory catch can vs the aftermarket cans. Looking in the PET I noticed that the factory catch can has an additional outlet/inlet. Where does that go? Why isn't it needed in the a/m cans?
It turned out the copper line and original fittings did leak a bit. Probably from the bending the pipe to fit.
so in case this is helpful to someone in the future:
i got some new AN fitting and a braided hose. 60 deg fitting at the front and 90 at the rear. In hindsight maybe a 120 at the rear would have been a bit more direct route but who’s counting ! I ran it in between the heater pipe and wastegate and used a clamp on the extra wastegate bolt thread. Nice and tidy!
now if only the rest of my engine and bay looked that clean. One step at a time!
That oil coming out of the turbo is super hot. Guessing 350 degrees. It's a good idea to keep that line away from the wastegate and other exhaust parts. The heat can transfer out of the copper tubing that the factory uses. The copper tub can be lightly bent in the area while kept away from the wastegate. The wastegate pipe could reach 500 degrees. I'm not an engineer or expert.
Thanks @Scott Dunavant I'll definitely keep an eye on it. I can also run it to the right side of the heater tubes if needed. That was my plan A actually but I saw a this more direct route but maybe it's not the best? Curious what others say too. I have a bunch of braided line left over and can remake it if needed. Maybe 3rd time lucky then!
@Metal Guru Paul - any chance you have pics of where your line runs after your 90deg fitting and how it gets to the pump? I was meaning to ask you earlier, but forgot!
@cobalt@Metal Guru or anyone else: i'd greatly appreciate any thoughts on what I did above and if this is going to cause issues. If so I'll re-run the braided line to the right of the heater duct tube. Many thanks as always!
das76, I think that you did a good job, so I am not sure what you are concerned about.
1) I bent my own copper line and brazed it for my project. This was a first and really easy to do. If you ever want to go back to Copper.
2) I am playing with a no-name catless A/M exhaust that I had sitting the basement. Other than ceramic coating the stuff, I did make a short stainless loop. Take a look at the pictures. I did keep it as far away from the exhaust as possible.
Thanks @Igooz yeah, i was just rethinking it after Scott mentioned that running it so close to the wastegate pipe/wastegate might not be a genius move on my part. It's easy to re-run it similar to what you have. I just don't want to if I don't have to !
You can always re-route the oil line or run a heat shield around your oil line. I have had excellent results with thermal insulation.
My exhaust is not BBI. The muffler is a magnaflow that I had modified for flanges and the tips I bought used off a guy not far from me. Everything else we made years ago. It really is No-name.
as far as keeping it clean, that is easy! It does not start anyhow!
Definitely. From everything I've done to mine so far, changing them made the most noticeable difference. You can expect a noticeable reduction in the amount of revs that your turbo starts to spin as well as the point at which you are making full boost.
Yes, there are bigger improvements to be made, but in terms of bolt-ons, it's probably one of the biggest bang-per-buck external mods you can do.
