Whilst changing out my tensioners, I used the zip tie method and removed the exhaust cam, before torquing everything down to spec, I am going to replace all of the bolts with new hardened steel bolts, however, I am curious to know what size the cam bearing cap bolts are, as I do not have them with me, does anyone know what size they are?

Rather than buying them from Jag/Ford, I am planning to find the same thing (if possible) from a place like Fastenal.

If anyone knows the size, or part number that'd be great!

Thanks!

 

What's wrong with the old bolts?

 

Yeah, i wondered that myself! These are not head bolts!

 

Brittle, pulling one out the head came right off!

After extracting it, I am not going to take the chance of them breaking whilst torquing them down.

And yes, I was loosening them, NOT tightening it.. It just a risk that I am not wanting to take when torquing them down again.

 

the bolts are m6x1 degree pitch 35mm long flange head grade 10.9
