tough questions- Fuel inlet ring bolts and

[just66horns]

I have a few funny questions. 72 tii-

1) I got my car disassembled, by someone else. I have all the parts for the fuel filler neck install, but I do not know the thread and length of the tiny little bolts (see photo center) required inside the trunk. The four holes in the inner fender are full of paint from the body shop, and I need to tap em prior to install. Just really need the thread m4?m3? or perhaps someone has a handful...

 

2) Engine assembly of a 2002 motor, being fitted with Tii parts. On the Tii, there is a secondary bearing cap on the #3 main bearing. It supports the oil pump pickup.  I have the Tii pump, but, I do not have that extra cap for the center bearing. Anyone have one? Other solutions? Engine is ready to go, but, not till i'm happy with the oil system. I guess I will need longer bolts too.

Realoem describes the tank screws as 'sheet metal screws' and from memory they do have a tapered, open thread like a self tapper. 

 

I would get hold of some and just run them into the holes (though they appear to be NLA) or try some generic self tappers instead. 

[just66horns]

No, they aren't self tapping. the diameter is way smaller.. But, I'll check closely. Anyone want to back a screw out for me?

Thanks

72, so you have the shorter filler neck, the ring with threaded holes, and another ring that sandwiches the rubber boot...

 

They're probably 3mm- honestly, I'd get the small taps, and have at it- start small, and get bigger until it taps cleanly.  Then buy fasteners accordingly.

The couple parts cars I took apart often either were already stripped or the little fasteners broke off as they were coming out...

 

I'd look, but all of our cars have a hose clamp there, instead, as they're the early Pinto style...

I backed one out. 

4mm self tapping screw.

Thank you Simeon. I really appreciate it. That tells me what I need to know. Your effort is greatly appreciated.

Anyone want to tackle the oil pump/center bearing issue?

So...

Are there any differences between tii- and non-tii pumps??

yes. the pickup is longer and deeper for the deeper pan. I have both short and long pickups, but the deep pan.

[Simeon]

Is it a deeper pan? I never knew that. Always assumed that they were the same in this respect bar oil feed and return to the pump. 

[rover1]

you need the e30 m10 oil pump+oil pan if you go that route 

[Simeon]

Thinking about it, how would a deeper pan work with the front subframe? The cross member passes directly under the deepest part of the pan. 

[just66horns]

The part I need is the center bearing/oil pump support. I can get the plate that goes between the two.  Dead center in the below drawing, from the factory books, you can see the oil pump pickup, the support plate that rises from it, and the angled add on bearing cap for the #3 Main bearing. This will require longer crank bearing bolts, and the cap. The vertical plate is available. I just need the cap and bolts. I do not need anything but factory BMW parts for a Tii, nothing more.  

[just66horns]

I think the difference is 1600/2002 difference, rather than 02/tii. The deeper pan may be on the bigger motor, and then should have the extra cap. 

[Henning]

Must be a US-only special...

 

As far as I know, all 02 from 66 to 77 have one and the same oil pump, pickup and pan (excl. the turbo with its return junction). If I'm wrong here, please faqers: beam me up to more knowledge.

 

Here's the support socket, #9:

 

 

And here the support plate #16:

 

I've got them both, but there will probably be somebuddy in the US, too.

 

Dazed and confused,
