Externally Leaking Headgasket

[Spoony]

I'd tend to agree, if replacing the head studs to retention in the 'hope' that it works (chances??) might as well go the whole hog.

After a bit of searching & reading I found a Nulon rep posting on a few forums about their seal-up product. Comments included assurances that it will not block or gunk up the cooling system if it's in a clean state already etc, and works for weeping head gaskets.

It's been in there not long after the early posts now and haven't seen the level drop even after some spirited driving and a hard skid pan day.

As gaz097 said, it's a fair bit of work, for what's almost just an annoyance. It seems for me it took many many months for the level to drop just millimeters .

Hopefully the fix in a bottle does the trick for a while.

Id get a head stud kit and try that first before you go filling cooling systen with stop leaks

Years ago I

used a small clear tube with what looked like fine metal particles of different colours ( can't remember the name of the stuff)to stop a leaking head gasket on a 202 Expensive Daewoo engine.

The leak was coming out of the head gasket and you could visibly see it dripping once it got up to temp, the gasket was still sealing the cylinders though.

Well this stuff fixed it straight away and lasted for the next few years until I sold the car.

It was just poured straight into the radiator.

Would I use this stuff( if I could find it again) to fix my turbo 6????

I would be a bit hesitant , I don't know?

You could do some pretty horrible things to those old cast iron motors and get away with it!!!

Yes I once owned a Holden, but only once!

One of the scariest cars I've ever had...... HQ ute 202 red, 3 on the tree( no synchro on 1st, jammed linkages) and all round drum brakes, it was a nightmare trying to pull her up in the wet wondering which brake would lock up first!

Really you'd try the hard labour intensive job first hmm I think I'd go the stop leak and see how that goes

It's a 230,000 km taxi motor though, bar the head they aren't exactly the latest design, not that much in any engine regarding head gaskets etc has changed though?

Chuck stop leak in and see how good your cooling system looks after some time
