hi all, my sons 3.1 trooper is pressurising its coolant system....the bubbles in the expansion bottle are intermittant,no white sludge anywhere,no smoke from the exhaust,power is fine,temp gauge reads mid range as l would expect,but it still pushes coolant out of the expansion bottle....new rad and water pump just been fitted,all hoses changed,l would expect to see some or all of the afore mentioned faults if there is a head gasket problem,but,other than the coolant loss via the expansion tank,all seems ok.....am l really looking at a head gasket fault???,many thanks,jack.
