Evening Gents,

Starting to accumulate the parts to rebuild the new engine... So the likelihood is this is the first of many daft questions!

What are the recommendations on the exhaust manifold to head bolts? I've heard people have used Allen key bolts before as it makes removing them in situ much easier.

Cheers,

David.

They go in at 40 pound foot, easy enough, but coming out they'll be corroded in, and I wd avoid Allen sockets like the plague, torx at a push. I wd stick with the 12 point 3/8 coarse, not perfect, but ok.

Might be worth considering studs, but it will then be harder to remove the manifold in situ ( ie you will need to clear the ends of the studs)

I got stainless Allen bolts and they were much easier to cope with - especially the one that's hidden by the steering column, where you can chop the end off a "ball end" Allen key and fit it into a suitably-sized socket to get the right angle on it.

If you remove the right hand inner wheel arch you can get at the hidden bolt from the arch, but must be either 1/4 or 3/8 drive, doing that bolt from the top is a pita no matter what type of bolt you use..

Thanks Chris.

In that case, I'll probably reuse the originals.

A clean with a wire brush on a drill/ bench grinder with wire brush ,cleans the bolts up nicely, with the inner arch off it’s a synch to get at the pita bolt.. I struggled with the first head job I did, soon found out that 5 minutes to pull the wheel and arch liner was worth it, lol
