Oil return line?

[BudmannG]

I am interested to know if anyone has o-ringed the oil return line? Specificaly the end that bolts to the pan. I am currently going to try this on my car. I will not be able to test it out until I get it put together and running.
I was just curious to know if anyone else has thought of this or tried it. Please give me your input!

Sounds interesting. How much labor is involved? Are yopu having problems with the return leaking?

It took me about two hours to do it. I used the -an fitting that came with the line. Marked the flat side of the o-ring. then laid the o-ring on the fitting center to the hole. Press ever so gently as to not mess up the roundness. Make sure you get a good mark on the fitting. Then use a dremel and a round cutting bit to groove out the area you marked. I recommend making the groove only wide and deep enough for the o-ring. I used a o-ring size of I/D=5/8, O/D=13/16, and the thickness is 2.62. I only went half way on the depth of the o-ring. I checked the size of the o-ring to the pan and it is a perfect fit to the hole on the pan.
It also takes a real steady hand, so as not to make unneccesary grooves in the fitting.

Interresting Idea.
too much work for me tho, Id just RTV the living hell out of it.


I always out my trusty sheet of heavy duty gasket paper material, trace the flange, razor blade it out, boat both sides with silicone, and bolt her up.

Sounds good. As a diesel mechanic, I've learned that o-rings work way better than gaskets.

Just keep in mind the common sense things: grease o-ring, torque evenly.

Should work great!
