So no ls1 then :-(

>>>tappin from tassie

I'm with Winnie on this one mate and good to do one thing at a time, start with the easiest and cheapest.

Yell out if you need a hand, just not this weekend working.

Yendor, you sure that fan kicks in at 100 degrees, if so that's a good way to check the accuracy of the temp gauge, both original and aftermarket.

Bugger that. I would give the entire cooling system an overhaul. If your problem is fixed at the end of it all, who cares what the problem was. It could be a lot of smaller things too.

I'm with Winnie on this . Especially with the cooling system most things would need coolant dropped... just bite the bullet if you can and give the whole thing a full flush and change bits while the system is empty.
Especially if that leak solution you poured in blocked up the system even more.

NO is a quick answer as I didnt think it was a big deal at the time

Maybe just get it booked in somewhere to find out what is the cause.
Then you can decide on what you can do.

Had similar issues (pressure building overnight etc). May not be what you want to hear, but does sound familiar :(

What does "holding residual pressure for a while after shut down" mean? Coolant not being sucked back into radiator as motor cools down?
Hate to say it but I also think it's sounding like either a cracked head or a cylinder head gasket blowing between cylinders. Given that it runs ok for 20kms or so before playing up I'd guess that the cracked cylinder head is more likely.

See thats a new [reco] motor right there,,, as the labour to fix the head gasket is more than a motor
I dont sit on a big pile of money here , I'm on a disability support pension,so options are limited so it may
end up being a boat anchor. Ill try and get most of the cooling system out over the weekend
