Havin problems with the water system on my p38. Engine has been rebuilt after co2 in water. All new parts fitted, wpump stat and cap. Top hose still gets very hard the vacuum guage was ok yesterday but today it just fails. Pump is pulling air in some were but not letting water out. Now totally [!Expletive Deleted!] off, C/Hd as been pressure tested twice and skimmed once. Bazz. :police:

Hi Mate
In my experience i have seen where the bled hose off the top of the rad to the expansion tank has been blocked causing all sorts of overheating issues, ensure that you get coolant out of this hose at the rad & then ensure it is completly free flowing into the expansion tank.
Good luck

Replaced the front chamber but air still in water, any ideas please cos iam nearly skint. Bazz.

Did you have the block crack tested?
Ive just had a new engine (well 2nd hand!) into mine and the original fault was the block, and that was causing it to pressurize and overheat.

Very crude but if you get pressure in the cooling when it's running try pulling an injector lead off to dissable one cylinder, check each in turn and you may find (I say may) that the pressurising stops. It can still pressurise on the compression stroke but the cylindder pressure is much higher on the power stroke.
Another solution is a leak-down tester. Kpet meaning to buy one when I had the cash.

:afro: Still having problems, with air in the water system. Its not C02 its air. The head as been tested twice and skimmed once. New pump,stat,front chamber and water hoses. Bazz :huh:

As i said before, have you had the block tested. Mine had co2 in the water, but ran some kseal through and it got rid of that leak, but still had major pressurization and it turned out to be the block.
I put a new engine in mine, which wasnt too bad, as there is a few engines about. Its the same engine thats in the omega 2.5 td and bmw 325 / 525 td's of the same era as well. I picked up a replacment engine out of a 325 for

It can't suck air in, it's a pressurised system. When it cools air is admitted by the header tank cap, if that was stuck you should see a hose collapse when it's cold.
So how/when is this air getting in, is it blowing air out through the header tank with the engine running? is it getting air locks anywhere and if so how do you get rid of them?
