Oil cooler line repair

atr911 · 12-26-2003, 10:54 PM

I removed my oil lines from my coupe to transplant them to my targa and have found that the one brass pipe is crushed in two places.

I know there are places that can repair this but my question is: Can I just use some good rediator or even aeroquip hose and cut out the crushed section and clamp on the hose inplace of the dammaged section?

Any info on brass line repair would be appreciated.

Sometimes some heat and a steel ball welded to a long rod (to push through the pipe) can do the trick.

I think it may actually be punctured at the one spot though

Sounds like a good excuse to call Chuck at Elephant Racing for some finned lines.

I for one would not be comfortable "rigging" up a fix on the oil lines especially given the stresses it sounds like yours have been thru.

Cut out the offending sections and braze in some repair sections. I vaguely remember someone using pipe purchased at Home Depot to repair his.

Repair or replace is a matter of simple economics. If you choose to repair the smashed / punctured oil line, cost is under $50, potential for failure is high, cost of failure is high (approaching $7,000 - 12,000). Cost of replacement oil line is high ($300 - 400 per line), potential for failure is low. Choose your risk factor wisely.

I'd be looking at Chuck's Elephant Racing lines. Then I wouldn't have to worry about a failure.

Adam:

Nobody has mentioned the good used oil line as an alternative to new. I'd buy new or good used. I would not rig anything with rubber or even brazing. If that oil line goes, you will buy a new engine by the time you find out.

Search "oil line repair" thats all I did.

I get so fed up with the opinions from the peanut gallery, listen to the folks that have btdt, they post but are frequently drowned out by "others" with their "thoughts",

Anyone know how much pressure is actually flowing through those lines at full throttle. I understand that I may be taking a risk but I believe that if it's done properly that the risk is negligible. I'm still doing research as i'm not anywhere near neading these lines yet, I do appreciate all yoru info and opinions.

Yes I have considered new lines, new finned lines, and used lines, i'm just examining ALL my options.

Also, I happen to have some extra hardline material (from the thermostat back to the engine) that I 'could' use as replacement donors

The pressure in the line is from the scavenge side of the pump returning to the tank.
I don't believe this gets much more than 20-30 PSI....but I could be wrong.
As long as the return line to the tank is not crimped or blocked...the pressure will remain low....restrictions will cause it to rise (also cause the temperature to go up because of reduced flow).
