What to use for OMP lines?
 
I know that leaking oil coolers destroy rubber hoses, so what can I use for OMP lines other than rubber? I need to fabricate some new lines and need it to be relatively simple, so what all works? They'll be going to a single port on the float bowl, so I can't just reuse the stock ones.

get a Wye or T fitting and windshiled washer plastic hose from Pep-Boys. The windshield washer hose is only to mate the orig op lines and the t-fitting. I dotn have the size handy.

BTW, im using GSL-SE OMP. Four lines reduced to 2 lines using the above. No leaks.

If I wanted to make new OMP lines, I'd reuse the rubber ends (if they were still good) and run some copper tubing to connect them up. Copper tubing won't get brittle and snap if you look at it funny like the stock OMP lines.

yes but how would you know when youe omp went bad seeing how youe cant see oil in lines now that they would be copper id just call a few junkyards or look in the for sale section. that would be best

well, if your engine freezes up, check the lines..

Junia 03-30-04 08:14 PM

you can always get rubber ones. just make sure you get something that won't go bad

Mazdatrix has a decent price.

The lines are pretty cheap, you're better just to buy them from your local dealer. I think mine cost just under $40 CDN for both lines on my '79.

The thing is, I'm not replacing the lines - I'm fabbing new ones. I'm going to make an OMP manifold that's one line running up to and under my intake manifold (sidedraft carb). I'll have a tee inline for rotor 1 and continue the line back to rotor 2. I'll tee there and run rotor 2's line into the manifold. From that final tee fitting I'll run tubing into the sub-zero assist which will have a manual switch. That way, I can still use my sub-zero (fill with ATF for James Bond smokescreens on demand) to bump compression up when she won't start.

That's why I'm running a single new OMP line.

Jeff20B 03-31-04 12:41 PM

ATF is bad news.

Lack of OMP doesn't cause the engine to sieze up, it will just wear out faster.

You can't see how well the OMP is working with the plasticl lines anyway. You need to pull a line off the carb and check the flow manually.

it was a hypothetical answer.:shot2:

Chairchild once said the engine will lock up if the OMP went bad. He was being serious. I was being afraid.

peejay 04-01-04 05:48 PM

I am being laughing heartily. :)

Think bout it... the OMP only lubes the apex seals. Apex seals cannot cause an engine to lock up, they just wear out. (Not counting carbon lock, which is unrelated to the OMP)

I found the thread. Scroll down a bit. http://frost.bbboy.net/vwengineconve...rum=1&thread=6

It's funny how he changed his story right after I corrected him. Then he besically repeated what I said to try to sound smart. Words failed me, but there was one emoticon for what I was feeling.

There seemed to be a lot of misinfo going on over there so I stopped participating on that forum. My loss I suppose, plus I sold my only VW around then, so there was no longer a reason to even bother with it.

peejay 04-03-04 10:07 AM

There's a lot of misinfo here too. Mainly there's a bunch of junior high brats who seem tothing they have to respond to every post even if they have know idea what the hell is going on...
