Oil return safety announcment

[Sidewinded_idi]

wanted to fill ou guys in on an issue I ran across to hopefully prevent the mistake being repeated. I use a -6 fitting on an aluminum oil fill cap for my oil bypass filter return and have it setup this way fault free for a while now. Yesterday I installed a large auxiliary oil cooler on the truck and decided to add a T and have both the oil cooler and bypass return through the oil fill cap.

Started up and idled fine but when I went to go into town it started smoking out the street behind me and the engine started to run away on me. I was able to get it shut down by pulling over and spraying my extinguisher into my K&N filter box and idled it the rest of the way back home with no issue.

The problem I found was the oil bypass has a restrictor that limits flow, but with the free flowing oil cooler returning in the oil was so much it was going straight into the CDR valve auction hose right below it and getting sucked in through the turbo and into the intake. I decided to run a fitting into my valve cover and return the oil cooler through that port and it's been fine but wanted to forewarn anyone to hopefully save another runaway scenario

Thanks for the info. You can also stop a runaway engine if you have a manual transmission. You come to a stop, put the trans in high gear, hold the brakes tight, and let out on the clutch slowly.

WMO injection!
bet that got the hair on your neck to stand up.

That's what I was thinking!

Oh it did! When I first headed out everything seemed normal and I looked in the mirror and the street was unrecognizable with all my smoke. I couldn't understand what happened and when I let off to slow down it started accelerating. I believe at idle and light throttle it wasn't enough suction but once I had the turbo spoiling it sucked it right up that tube! And I wish I had a manual to drop it in high gear but I don't, that's why I always keep my fire extinguisher in the vehicle!!!

Also I got to comment that my fritz oil bypass kit came with a cool tool I never used until this. It comes with a punch you hit with a hammer to make a certain shaped hole in sheetmetal. I used it on the valve cover and it comes with a fitting that threads perfectly to the shape of the hole with a rubber seal and 1/8 npt threads. That's what I used to return the oil and it's working beautifully! Highly recommend it for an easy return. The old instructions say to use it to punch in valve covers, oil pans, whatever you want

I should've taken pictures of the scre in fitting but it's basically a tapered coarse thread matching this profile with a rubber seal and female 1/8npt on the end

Pardon my ignorance, but what's a "fritz oil bypass kit"?

Ah ha! That makes sense, I'd never heard of Fritz filters

 

[saburai]

That looks like a worthwhile mod. I'm assuming that for the idi the universal kit would be correct, correct?

 

[79jasper]

Yep.

I don't see why the 7.3 psd kit wouldn't work, same oil filter head.

 

[79jasper]

But on the PSD it's using the oil port, not the filter mounting flange.
I don't know that the IDI has that port on the header. But it does have them on the block. Or you could drill/tap it. Lol

Yeah just use the one behind it, the lines aren't premade so no issue there just lengthen it some

Wonder what the internals of that engine look like after a run away. Had to exceed well beyond 1200 degrees even if it was for a short amount of time
