Isn't there people who have eliminated the AST tank to avoid these future problems??? Well besides buying the aluminum one to replace it.

Yes, lots of people eliminate it. There seems to be some differences of opinion as to the elimination or replcement with a metal ast tank. Do some searches this has been discussed several times.

actually I asked Mahjik about this question and he's given me a real good break down on this subject:

The AST is there to aid in removing air bubbles from the coolant system. I recommend keeping the AST (as in an aftermarket aluminum one).

I have the Pettit AST, but would recommend this one instead:

Without the AST, it's a pain to get all the air out of the coolant system. If you don't mind trying to burp all the air out of the system for about a week, remove it.

It also adds more coolant to the system, which is another bonus.

Yes, very nice looking tank. I still have a stock tank. May be time to upgrade. I'm also looking at doing the radiator at the same time.

Mazda used an AST on the 787b, that should be a good enough answer.

and yes, more coolant too.

Caps...which caps goto the filler and which goes to AST (i.e. the cap's pressure)?

Thanks

The Filler gets a solid (no press relief spring) cap and the AST gets a .8 or .9 bar pressure relief cap
