Thread: DE Oil feed questions

Hey guys, I'm in the middle of rebuilding my engine and it's currently on a stand - about to get hot tanked in the coming weeks. I'm trying to tidy things up a bit with the rebuild. I have a few questions about these two locations for a closer oil feed line for my T28.

I have a DE block, and I know the stock oil feed port is sealed off. I believe I've read it can be tapped, but I risk getting metal shavings in the block. My question is - how good is a hot tank really? Should something like that get any shavings out if I were to drill and tap the stock location (top hole).


Also, I'm curious as to what these two ports circled in red below are. I tried searching and couldn't find much. Both have allen wrench heads on them. I opened one and it looked like it could have been an oil port of some sort, but I thought I'd ask here for sure.


I'm currently rocking a GFD oil feed line, but I'd like something a little more discrete and shorter.

T of the oil from the rear oil pressure switch

That's what I'm already doing, I just would like something a little shorter, eliminate one more thing going from front to back and clutter.

i wouldnt take the risk

Ok, well I'm still curious as to what the two ports are below the 4th exhaust port. Any ideas?

Bump. Anyone know what the two ports are circled in red for sure?

My thought was if these would make a good oil feed port I could try to find a fitting to work with it and use that, eliminating the need of the long feed from the rear. Like I said, I am just trying to tidy things up with the rebuild. If those are no good, oh well.

If you like water in your oil then use those "ports".

So they are water ports? That was all I wanted to know. Had no idea man. Thanks.

i would just stick to what you have, a lot of people use this route and it works... if it doesn't need fixing then i wouldn't.

There is nothing wrong with my current setup, I just figured while it was all apart I might try something new or a little less noticeable. I want to do everything I'll ever want to do with the engine out while it is out. Just trying to cover all possible bases. But if there is no better option, I will stick with my GFD line.
