The game is afoot.

Have now found that there may be 3 broken studs Doh!



Its no surprise really that it was blowing, not sure if it was the penetrating fluid or what, but even the bolts that were on there came undone very very easily.

Possibly looking at a leaking rocker cover gasket also (looking at the left side of the pic) and the thermostat housing looks like it has been bodge sealed (or is that normal?).  Dread to think what else I am going to find the deeper I go!

That's not looking too good.  I wonder if they've all been caused by the leaking thermostat flange?

I would speculate that coolant leaking from the failed seal of the thermostat flange has corroded the nearest stud, or just thermally shocked it.  Then once that one's let go, the manifold is no longer supported evenly, so the next stud gets loaded too much, then the next once that one's gone... :-/

What's the plan now? Drill and easy-out or head off?

Good luck anyway.

I have easy outs but the problem is getting access to drill out those studs.  There isn't much room unless I take out just about everything from the right side of the engine bay (battery and cables, power steering reservoir and pipes etc.)  It may be easier to get the head off but might have to bite the bullet and put it in the garage to get it done.

Im picking up all the gaskets, new studs + bolts etc tomorrow and knew it needed a new theromostat so will replace that will I can get to it easy.

No idea how long it has been like that, it looks like its been 'patched up' for a while.  Will probably replace all the studs incase any of them have been over stressed due to it being unevenly mounted and they are dirt cheap.

If you have a torque wrench and cam lock - just whip the head off - probably easier

Unfortunately I don't although seriously looking at getting them as, especially the torque wrench.

Well worth getting, it is nice to be able to do your own repairs

Well ive sourced another drill which I recon ill be able to get to the broken bolts with.  The thermostat is coming off anyway as it needed a new one, so that will give me a bit more room at the end.

Been putting some penetrating oil on all the studs today, will probably replace them all anyway, and have got all the studs, bolts, gaskets etc that I need to put it all back together.
