Car overheats under any load

(3k+ revs with light or more boost) within a relatively short time.

Have refilled and bled

(radiator and heater core) but I'm getting the same symptoms.

There's a lot of air coming out of the system every time I bleed

- a lot more than I expect

- and a lot of crap too, which I put down to be 20 year old corrosion of the pipes

/ radiator.

Think there may also be trace amount of steam from the exhaust tips

(oem) but this doesn't seem heavy enough to confirm.

Looks very much like a case of coolant mixing at some point with combustion gasses but I could be wrong

(hope I am).

Peter recently investigated the coolant system for a suspected leak

(I had photos from when I'd found lots of coolant dripping from the front of engine bay and suspected hose from hell) but he didn't locate any leaks even after pressure testing at 14psi

- replaced radiator cap.

After a lengthy motorway drive I had a overheat and now the problem repeats itself regularly where revs exceed 3k

(eg above 60mph or when pushing on).
