Exhaust sump bolt

[s p a c e m a n]

I've been playing my favorite Saturday game 'Guess whats missing'

Have had bit of an exhaust blow from the bottom of the downpipe and whilst sorting it out I realised that the cause is probably the lack of this bolt, what I can't find out though is whether it goes into the top hole (the one you can see) or the bottom one hidden by the bracket, the bible hasn't helped. Any idea what goes in there too? Tried to borrow a bolt and the one holding the MAF to the wing seemes to be the right size but wrong thread.

From memory it is 1/4" unc.

The bolt goes in the lower hole, I don't think the upper hole is even threaded on my car.

Thankyou, I'll have a dig around at work and see if I can find one to fit now I know what I need and where it goes

How funny, realised mine was missing on Friday evening.

Thanks for the info on size.

Likewise, noticed mine missing a couple of weeks back when working on the exhaust and was about to start looking into what size it was as nothing I had to hand fitted!
Thanks for the info.

I think you will find that bolt is 5/16" unc thread (1/2" af head). Happy TVRing

Correct

And I would advise a stud ~ much easier to slot the exhaust on rather than fiddle trying to line up and cross thread

Inch long?

I might just buy a pack from ebay rather than spend half an hour of my life rifling through pots of crap

Same size as sump bolts/studs then?
