exhaust stud leaking water.....

[sambo]

removed an exhaust stud from my 2h (60 series) and water flowed out
the stud in question was the bottom stud on the sixth cylinder

obviously the wall through to the coolant gallery has packed it in. any suggestions on how to fix this, without getting a new head

if i just stick the stud back in the hole the coolant cooks to steam and then fries the exhaust gasket leaving an aweful tick. therefore just leaving it is not an option, also dont want to risk damaging the aftermarket turbo which is fitted i.e. steam entering the turbo.

any help appreciated, as im short of time & cash

or even if some has a 2h head that they would let go of cheap

pull the head off and take to a machine shop
see what they can do with it. if not find a 2nd
hand one.

Hi,
Before you pull the head off, try putting some holden head stud sealer on the bolt. That should seal up the hole. I may have been drilled through from the factory, it happens some times.........

P.S. You can buy the stuff from any holden dealer, but our local REPCO store stocks it to.

any kind of high temp sealant will do the trick, even the high temp silicone type sealants are good for 300+ C, coolant temp will never exceed about 140 so no worries there.

I got some of the holden head stud sealer and put it on the stud yesterday, and i will put the gasket and manifold back on tonight.

That stuff better work for the price that it is.
