Substitute for camshaft sprocket securing plate?

[EcoAuto]

Today I pulled the head to send to the machine shop for valve work. In the process, I noticed there's a part missing from my camshaft sprocket.

PN# 11310631110 is a securing plate for the camshaft sprocket. The part is "ENDED" with the notation "See SI 110582004" Can't find anything on this site, or anywhere on the internet when I search for either PN#s.

This plate prevents the 4 hex bolts from backing out. I'm looking for someone with a spare OR a substitute solution. If there is a source, or a close-up photo of one, that would help. I might just fabricate something.

Loctite had been used on the bolts, and that seemed to do the trick since they were still tight. However, given the ugly consequences of a bolt coming lose and getting eaten by the timing chain, I'd rather do it right. What solutions have people come up with? It's part #2 in the attached:

Find a lid from an old 5 gallon pail with the crimp lid. Cut one out and drill. Small tin cans are too thin and spring. They are simply rectangles with extra length beyond the bolt holes for bend over tabs.

Locknuts? These are cap screws that hold the sprocket to the camshaft.

I like the 5 gallon paint can lid suggestion. I'm sure the machine shop I'm having do the head rebuild could easily replicate the part. It would be great if I could give them a photo of the plate so they can match it closely. Anyone have a photo?

When I was putting my motor together I could only find one of those locking plates. BMW says NLA. So I used lock washers and locktight on new bolts.

Red locktite works fine. It's what I use and I've never had one

come loose, not even a little bit.

I actually WOULDN'T put lockwashers under

there because I am paranoid, but I'm sure it wouldn't hurt.

Machine shops charge $85 to $125 an hour.

It would not be difficult to spend half an hour on making that part.

...you can buy quite a bit of loctite for that...

True, but LockTight is actually expensive.. I mean not by the drop, A bottle is like 30 bucks.

Reviving an old thread. I'm going to try blue locktite and the paint can lid idea. I don't want to have to blowtorch my cam sprocket to get the bolts loose. Anyways what's the torque spec? The page I used in the past disappeared during the update.

 

Edit: 10NM for an E30 M10. That's what I did, it seems fine.
