Oil line routing for a six. Options

[pete-stevers]

I am building my second 914 and putting a 2.4 six in and building it with hopes of building it out to a hotter 2.5 long stroke next winter... So I am putting in a external cooler up front. I am looking for the best ways to run the lines.. I dont want to run GT hardlines. What did you do?? Pictures welcome!!! (IMG:style_emoticons/default/biggrin.gif)

Thanks for all the responses. And sorry to hijack the original posters thread. I purchased Ben's hard lines but decided I did not want to run the lines thru the passenger compartment. My oil cooler I am using has the inlet and outlet on the passenger side. I am looking to run lines up and back on the passenger side. I would also consider one up the passenger and one back down the drivers side. I do not plan on going into the Frunk at the very front of the car. Most of the installs I have seen that run lines down the passenger side come out into the frunk at the passenger side rear. This requires going into the space occupied by the gas tank and then coming into the frunk. What I have not found pictures of is where people go into the gas tank area on the passenger fender. Would love some pics. What looks to make the most sense is to go in at the top rear of the passenger fender and then down under the tank to come into the frunk. Any pics of this type of configuration and comments welcomed.

Just be aware that any significant change in elevation will make oil changes a bitch.
Going over the top of the fender will make the lines run higher than the top of the oil tank which may also introduce issues.

Isn't this the situation on any 911 with front cooler?

And your point is? (IMG:style_emoticons/default/confused24.gif)

If you have a significant high point in your routing, you will need 2 (or more) drain points in the system.
On my car the highest point is the small hump for the steering rack which can be overcome by jacking up the front of the car. I only have one drain at the lowest point close to the tank.

If you route your lines over the top of the fender you will need to add another drain point to the front of the car to be able to get oil out of that part of the system.

Simply wondering what issues it was introducing, other than the drainage problem. I did always wonder how 911s were draining the cooler lines. (IMG:style_emoticons/default/confused24.gif)

There is always the debate or personal preferences of having (or not) hot oil lines inside the cabin due to heat but mostly risk in case of failure or collision. Failure probably is low, but collision is not controlable.

As Mark mentioned, there doesn't seem to be a perfect option only compromise.

I've seen oil lines come apart at the track twice (not on my car), one time resulting in a spectacular fire. Both times the failures were at the fittings, not the lines themselves.

So yes, failure and collision are most certainly a concern.

That is another big concern of mine... hoses coming apart.. What fittings are the most pressure resitant?
Andy Do you recall the fittings that where used on the two cars..
Engines are worth to much today to sacrifice to poor fittings (IMG:style_emoticons/default/dry.gif)
What type of pressures run through the lines? I will be using a stock pump not a four rib. I figure pressures can run pretty high on a cold start up or high rpm
What size lines are optimal?
