It will be many weeks until I have the engine in a semi-mockup state to be able to determine final options on the external oil filtering.
I would really like to implement the bold on option since it will make a huge difference in the general longevity of this engine.
However, my choice to return the EGR system to fully functional, adds a physical block into what otherwise might have been an optimal place to run two 1/2″ oil hoses.
Now there is a chance I can run the 2 1/2? supply and return oil lines between the EGR filter and its pipe up through the tin.
I’m not sure how hot the EGR filter metal gets though. It is pretty thin given how many of these units you see rusted and rotted away. It is sucking some exhaust gasses so it won’t be totally cool.
From the above angle looking at it from under the fender, I’m thinking that there may be sufficient clearance for these oil lines at B or at C.
If I was to wrap the exhaust pipe from the 3/4 heat exchanger to the muffler, that would definitely help with potential heat points.
The above image is slightly distorted, and the Muffler to EGR filter pipe (A) is rather small.
I don’t think I’ll have a real good idea what to do until I mockup the engine.
The Maxi Pump 3 has been delayed by UPS for another day or so. While it will be easy to mock the engine up with the tin, filter and even pump face, I don’t think I’ll be able to get a good idea of the clearance between then Muffler to EGR filter pipe and the bottom of the body until I actually have the engine back in the car.
I’m hesitant to run the lines through the gap at C just because it exposes the lines to the road even more so than at B.
I also don’t want to cut original tins to run the oil lines up through the engine bay to a filter mounted on the back of the firewall. Not on this car.
I’m almost to the point I think it will just be easier to go with a stock oil system and no proper filtration.
