"Different" Bolts - Any Reason?

bigbaldbloke · 5th March 2014, 19:56

I mentioned in a different thread that my EGR valve is held on with normal bolts, not the hex-heads mentioned in the manual. I figured that someone had changed them at some stage.

But now I'm trying to clean/change my PCV, the wiring loom bracket has different bolts to the "normal" too - they're just male torx with no 5mm bolt base (meaning I can't use a socket to get them off).

Could there be a reason why mine is different to the norm?

I've seen a couple of different bolts on both of these places on my past 75s - I assume people have replaced them due to damage or loss.
Or it could be different years had different bolts?

same reason the MAF has security Torx screws, to stop people from tampering with them...

A 5mm small socket will remove the wiring loom arm bolts easy, click the link.

That's the problem though, it won't! I can see that the other security bolts in that area have a socket-friendly 5mm base, whereas for these it's "just" the torx male head on a narrow shank. I've tried a socket just in case and I might as well have been holding a lump of jelly.

Hi Kevin.
The torx head may have been rounded off a bit if so try a 4.5 mm socket if not small mole grips will get them out once out you can change them as they are only self tappers really into plastic

Cheers for the advice - they're weird as it looks like they never have had a socket base. Mole grips are the way forward, ta for that!
