Exhaust Manifold - Advice Please

Post by Doggy »

Forgive me for posting a non-pug problem, but I'm hoping someone has some suggestions for this one.

My son's 1.4 mk3 Golf, (AEX engine), had a leak from one end of the exhaust manifold / cyl hd joint. Muggins here tried to tighten it up with predictable results :oops: Now have 3 good studs out of 5 :frown: I managed to get one of the broken ones out, but the final one will need drilling. Engine is tilted forward slightly so you can only see it with a mirror and there's no hope of getting an ordinary drill betwixt cyl head and radiator housing.

I'm therefore tempted to try putting it back with 4 good studs. it has 3 along the top, (which are OK - centre & both exteme ends) and two along the bottom, (between 1 & 2 cyls & between 3 & 4) - this last one has the broken stump in the hole.

My questions are:

1. Any idea where I can get spare stud(s) on a Sunday?
2. Anything I can use to improve the chances of the gasket sealing with a less than perfectly even pressure on the fixings?
3. What's the chances of it holding on 4 out of 5 studs, if they're all in good nick?

This is a very common problem with that engine. :frown:

The stud threads should be standard 8mm, therefore any 8mm stud from any car will fit, if you cant find a stud use a standard 8mm bolt with a spring washer and a flat one.

If you have the manifold right off, buy some exhaust assembly paste and fit it between the gasket and the head and gasket to manifold with extra around the broken stud.

If it is at all possible, you might be able to drill into the aluminium part of the head next to the broken bolt and after tapping a new thread, file out the manifold hole so that you can get a new bolt in.....I did this a couple of months ago on a Nissan Patrol, the broken stud refused to drill out...broke several drills trying, so I drilled the aluminium part and threaded that filing out the manifold so that I could fit this new bolt.

That's great news jasper! Decent apprenticeships are a rarity these days, (as I'm sure you know).
