Might be a bit of a long shot but I’m after x2 Sigma 4/4 cam cover bolts as pictured which are standard fitment on the Sigma engine. Unfortunately my local Ford dealer tells me they are only available if you order the full kit including the cam cover itself which is cost prohibitive. Any help in obtaining them would much appreciated. Thanks. ![[Linked Image]](https://i.postimg.cc/vBSXCbKx/A0-B71-D8-D-1-B78-45-F9-84-E7-6-E1-D5-F7-EE65-D.jpg)

Would it be possible to use a length of stainless metric studding with a Flange nut and a locknut as a substitute?

It looks like a stud bolt. Did you mesure the bolt and surch for it?
Or use a bolt that fits and cut off the head?
2005 4/4 1800ccm Duratec and a lot of HONDA CX500.......

Both of those are possible if I can’t source the correct bolts.

Those are not bolts simply studs and flanged nuts by the look of it. If you remove the nut then lock together two similar thread nuts you should be able to extract the stud from head. Suitable plain studding cut to size and locktited in could replace. You haven't explained why you need "bolts" in the first place though

Richard, I hate to say but they are all one piece. A Ford special. They look the same as those fitted to the Duratec and may be other Ford engines. So I would try a scrap yard. On some engines they have a rubber socket srewed onto the top thread to mount the engine cover on.
Cheers
John.

Suitable plain studding cut to size and locktited in could replace. You haven't explained why you need "bolts" in the first place though kev has a Sigma engine cover that he wants to fit, he has this set up on the manifold side, and has the studs with nuts on the inlet side. He wants to install the studs so the new engine cover fits over the top without the need to remove the main cam-cover bolts when you need to access the spark plugs. ![[Linked Image]](https://tm-img.com/images/2022/10/26/502452CE-0006-43E9-B54D-43E4496CBBC8.jpg) So the cover fits like this one ![[Linked Image]](https://tm-img.com/images/2022/10/26/0EC03996-2FD7-46AD-8DE2-0977769ABEA8.jpg)

Here is a pic of the Ford stud and cover mount. As I said in my previous post I would try a scrapy. Or you could just use studding ("all thread" as is the modern term that I hate) with a nut glued on. Cheers John ![[Linked Image]](https://tm-img.com/images/2022/10/26/DSC03857.md.jpg)
