Using engine oil to heat the fphe

[speedtuner]

I thinking of some outside the box ways to get more heat into my system.
What about putting the fphe on a seperate loop and using engine oil to heat it vs. water. From what I read the engine oil temp is usually 20deg hotter than the water. I'd be easy to tap into, there is a plug right next to the oil filter.(guys use this for bypass oil systems). The only question I have is how much flow actually come thru this port?
I think it could work, I would think I'd get heat to the fphe faster and hotter.

This sounds like something worth looking into.

I've got no real world reason why it wouldn't work. Clogging issues maybe?

only negative thing I see from it is that eventually in the summer it would act as an engine oil heater but I think that is a very minute point.

Couple things I wonder about are how well oil transfers heat vs water. And how much flow actually comes through the 1/8" NPT oil port plug next to the oil filter.
Any ideas?

Are you really having that much trouble with heat in your system? Why not get a bigger FPHE? There is not much volume coming through that port and I have read in threads about oil by-pass filters that this port can not be a wide open flow because it takes flow from the motor.

I have decent heat, but I wish it was about 10-20 deg hotter under light load conditions. I get about 150-160 under light load, city/country driving. Pulling or highway its no problem.

you could put a 203 degree t-stat in.

I get 190 degrees consistently with mine, regardless of load conditions.
My 30 plate HE is mounted in the valley and fed from the heater core line.

Even if I shut off the coolant flow I still get over 100 degrees just from the radiant engine heat.

I have the 203 deg t-stat and 30 fphe.

What kind/brand of gauge are you using to measure the temp? I stupidly put in glowS*H*I*T gauges to watch coolant temp, VO temp and pressure. Guess what I found?! all 3 were WRONG and even after replacing the senders (replaced under warranty) they were STILL WRONG! I now have isspro ev2 gauges and they are correct and look nice too

I'm using a Autometer oil temp gauge. I've always used Autometer in the past on other projects and race cars and always felt they were accurate, so I have no reason to feel that this one is any different.
