WTB: Oil filter flange

[jrcook320]

title says it all. I need a new one, my turbo oil feed fitting threads are stripped. Paging Charbel!!!

[bflan2001]

i've got one, i was going to tap it and sell it on ebay but i'll trade you for a diff bracket (whenever you make yours, i'm in no rush)

[epmedia]

When you turbo folks drill into your stock oil filter flanges and tap a hole for the oil line; do you use pipe threads for a hose nipple? or straight threads for a pressure fitting? Or a combination?

I've got one too, but you'd have to buy the whole shortblock to have it (trying to sell the 2L shortblock) .

Just curious, Robert

[pthm]

there is currently one on ebay

[pommeree]

Would one of these not work? (not fit?) Just curious.

JR in case you are not aware, some of these pieces are much thicker in the area you want to drill. The thick one will hold like 6 threads vs. 2 for the thin one. Definitely worth finding the right one, you can easily tell from the outside. Maybe Drew has a pic of his.

Layne, you have my old piece - but I can get a picture of the one on my car. I'm not sure if one is from a 2.0 vs a 1.8, but layne is right, the difference is very apparent.

[jrcook320]

That's for an oil cooler which would be a good idea for me but with my charge pipe routed where it is I don't have room without getting into some fabrication. I still wouldn't be able to use that for the oil supply line for the turbo though, so I'd still have the same problem with the flange I have.

[E21Adam]

Josh, I can grab one off my spare m10 and mail it to you for free. PM me if you want it

[Layne]

Thats the thin one you got there, very easy to strip out.

[bflan2001]

the one i have is from the early E21 and has a thick, flat surface in the center.

Sheesh. I just water at the mouth seeing those pics.
Good point though. Sandwich adapter as turbo oil supply would mean routing all the way to the turbo and then back.

I assume you're running an oil temp gauge.
Are you using the drain plug sender or different kind?
Thanks,

I didn't know there was a difference. Thanks guys. I suppose I should get the earlier style then.

yeah, you can't do that since the oil drain needs to be at 0 pressure and the turbo oil flow rate is very low. Trying that would cut off oil flow to the engine and cause major turbo seal issues.

I'm running wide band, boost, and oil pressure. I'm out of room for oil temp, but that is one I'd like to add. For now the mobil 1 and water cooled turbo helps protect agains oil degradation due to heat.

[bflan2001]

this is the one i have, you can see the extra material. pm me your address if you want it. back when i put in my oil temp sender i looked into which models had the flat spot, and iirc it was just the early E21s. 2002s, e30s and late e21s don't have it.

[jrcook320]

I'll let you know...

Do you know the diameter of that pad? It looks like it's a little too small to be of any use for a 1/8 NPT tapped hole (roughly .328" drill size)

No, it works fine. I did the one on drew's motor with 1/8 NPT.

[epmedia]

Yup, Plenty big for 1/8" npt. Mine ('78) is about .650" on the flat pad. Lots of meat there. There's even a center dimple to start the drill bit .

Well if you want to put more than one fitting, I can make a sandwich plate that goes between the oil filter block and the engine block. It can be tapped for any number of fittings. Its a much cleaner look than having pipe T's all over the place.

Thanks, I'll keep that in mind. For now I'm just going to tap it for an oil feed, I have no immediate plans for an oil cooler.

I still have to get that flywheel in the car. I'll let the forum know how awesome it is. I finally have a good clutch disc from clutchnet. The first one was damaged, the second they sent was a 215mm. Now I'm waiting on a 22mm flywheel bolt exchange from bavauto.

[jrcook320]

bflan2001, I tried to PM you back but your box is full.

do you want money for shipping or just do a direct exchange for the diff mount? I can work on fabbing them up monday and/or tuesday night and just ship one to you if that works for you.

I got the filter flange installed over a week ago. I bead blasted it, then cut the un-needed bracket off the top:




drilled, tapped and cleaned up a few burrs:





I radiused some large casting burrs to improve flow over some sharp bends on the inlet and outlet passages:



then painted it with "aluminum" engine enamel and clear coat.



Here you can see the old style vs. the new side by side. The old style clearly has a much thicker area to tap, but other than that the new style appears to be a better design. The flow passages are radiused for better flow, the filter inlet passage is smaller so less oil will dump out during filter changes, and the filter seal flange is ribbed on the new style for better sealing. Oh well...

[epmedia]

Awesome Josh.

Is it too late to port and polish it a little more in the flow areas, if there's enough meat in there? That may help the flow even more than what you've already improved. (ie: a dremel with a sanding drum).

EDIT: Nevermind, I just read that you already have it installed.... The page did not fully load when before I commented.

Looks Super, Robert

If you still need one, I have an oil filter mounting flange from an '80 1.8 litre - Ian (Ontario, Canada): pringle_5@sympatico.ca

No, it's not possible, there isn't enough material there. The wall thickness is less than 1/8" thick and it is cast with a sharp bend at the points I radiused. If you look at the outside pic of the 2 side by side you can see the same sharp bend on the outside of the old style vs. the nice radius on the new style.

It's clear as day to me now, good judgement on that porting mod.
