thanks to LOADS of help from peep on here iv had my escort up and running for awhile now and love it
if fact i love it so much iv bought a fiesta rs turbo for some efi fun as i wanted to leave the escort mfi!!

i bought the fiesta as a non runner and have since build up a new engine and fitted it but now i have two strange problems that i cant seem to get my head around so thought u guys might b able to help....

the engine idles fine but when i rev it i am getting a build up of pressure into the coolant system?
as if im loosing compression into the cooling system but the cylinders all have and hold compression and there is no sign of leaking from my leak back tester.Also the cooling system is holding pressure????

the other problem is that it seems to be breathing heavy?
if i remove the oil cap i seem to have to much pressure.

these probs could b linked as they are both pressure related but i cant see where/how the pressure could b leaking?!
any ideas??


also could someone post a pic of where the two pipes go to and from the control valve solenoid that bolts to the air box



thanks in advance
