EGR Plate and Manifold

I'd been interested in cleaning up the engine bay for a little while to get rid of some of the multitude of vacuum lines and eliminate some potential sources of air leaks.

No before picture, as I was too busy also draining the oil for the second time in a week to try and eliminate some of the valve train noise.  Now replaced with a new K&N filter and 5 quarts of Royal Purple 10w30.  Engine seems a lot happier now!

Anyway, EGR plate fitted - I couldn't shift the bolts for the pipe underneath, but the studs came out easily enough for the EGR valve.

Whilst I was there, I was looking for some of the causes of rattling.  Spotted this on the exhaust manifold:

I don't know if this is intentional or not - there's about 10mm gap in the manifold flange and the nut was missing from the stud.  It sounds like it's blowing pretty heavily as well, so...

That's a 6-1 manifold with a 2.5" collector, ceramic coated.  The welds aren't the prettiest, but it seems fairly good quality.  Because I have a 1978 with the round manifold ports, there really is very little choice available.

I'm happy with it, so I'm going to arrange the car going into the shop to get a new 2.5" stainless exhaust fabricated.
