Turbo oil drain line using push loc hose?

[TR Custom Parts]

With all the fuss about fitment with braided line for turbo drains and the stock one always leaking, how about using Gates push loc hose and fittings for a drain setup?

Really tight in that area to use regular fittings, ask me how I know.:smile:

Braided stainless steel line is really just rubber hose with a braided outer covering so don't see why push loc wouldn't work? Should be able to hold up to the heat, been using it for my oil cooler lines and accusump system without any problems and they are under pressure.

No reason it wouldn't work. It has the same temp range as braided. So, if you lay a braided hose on your exhaust pipe it will burn the inner rubber line, too. They make flame/heat resistant covering for hose. Ask your local hydraulic shop for it. It looks like this: http://www.bakerprecision.com/images/firesleeve.jpg

Yup there's no reason it wouldn't work. I already had some extra -10 line laying around and thought about making one when I couldn't get my aftermarket braided line in place without it kinking. BUT at the time I was getting impatient and it was just simpler to re-use my stock line which isn't cracked yet.

Get the correct length of line, fittings that SWIVEL (I think 45degree fittings would work best at both ends), and supply the flange that bolts to the bottom of the turbo.

There's really no reason for this line to be braided, it just makes installing it a PITA, ask anyone with the aftermarket line.

Push-on (hose barb) fittings work fine, I even use them on my oil cooler lines which are under pressure and don't have any leaks, drain line can handle it easily.

The main obstacle is that both areas where the line screws in is very tight. Must make sure the provided fittings will clear. You don't have a ton of clearance at the center section of the turbo, and it's even tighter back at the block behind the water pump. Like I said, when I was eyeballing it myself to make up my own line, it seemed that 45 degree fittings would work best and most closely follow the bends that the OEM flex line takes.

If the braided hose that is being sold now was an actual swivel it wouldnt be so bad. Its just a fitting that the hose gets pushed onto then crimped.

After you fight with it for a half hour, the fittings actually do loosen up enough that you can spin them like a swivel. Still didn't help much.

It's just a poor use for a braided line. Large diameter braided line + fairly sharp bends = not happening.

Hi Mark,
I spent a few years as a hydraulic fuel systems engineer and found out the hard way that teflon hose is the best way to go for handling hot oil in the long run. Some materials (even those spec'd for use with oil) had serious issues with hardening and cracking after prolonged exposure to high temp oil. We're talking 250F+ and 1000Hrs+.

Oil temps on a Buick certainly won't get that hot for that long, but I just wanted to throw it out there.

Hopefully will be offering two versions of this. Got a small fortune in fittings I can't use for this already but got some more stuff coming that should work out fine. One will be with braided hose and another with the push loc. Each version will use different fittings.

Sounds good. Having problems with the "other" line out there right now really had me wishing there was an alternative. Make yours more user-friendly and I'm sure most of the market will come to you.
