How did you run your oil lines?, The good and the bad...... Options

[PRS914-6]

I'm getting closer to installing my -6 oil cooler and lines. I have seen numerous ways of running the lines incl through the longs, under the rockers etc. but I have not decided yet. If you would comment on how you ran your lines and the positive and negatives of the end results, it would make a good thread and go perfect with the recent oil cooler thread.. Pictures would be helpful.

I ran mine through the heater tubes. I figure I can always change this later of I want. I really wanted a different solution, but when it came down to it this was most practical. I'd probably feel different if I wasn't running headers.

I also decided to put the thermostat on the firewall. I've heard arguments both ways (upfront vs near engine), and both arguments seemed to have merit, so I just went with what gave me clean routing. I used 2 1/2" Fernco caps at each of the entrance/exit point in the heater tubes and they work great. You just cut an undersized hole in the middle of the cap and pull the lines through. It seals the tube and centers the oil lines in the tube opening to keep it from chafing.



Where the lines exit the tubes, I brought up through heat tube holes and then down under the tank. I used 45 degree bulkhead fittings at the trunk wall, but this is probably particular to my cooler install.
