| 2.2 head gasket (probably) | |
Unfortunately, the car has been using a bit of coolant over the last couple of months at a fairly steady rate, not huge but needs regular top-ups. It also holds a significant pressure in the cooling system, even when left for a couple of days. Doesn't run hot, thermostat is working fine. I had hoped it might be the coolant cap so changed that (twice), but still the same symptoms.
There are bubbles showing in the expansion tank (small but regular) and so I did a couple of tests of the air in the expansion tank at the weekend which showed up positive for combustion gases  . I have isolated the EGR and EGR cooler from the cooling system and the bubbles still appear which seems to point to head gasket failure or cracked head (hope not). Although no white smoke, oil in coolant or coolant in oil, but I can't see what else it could be.
So, apart from replacing seals and stretch (TTY) bolts along with the head gasket is there any other parts I should be replacing whilst it's all apart? Car has 160,000km (100,000 miles), would it be worth renewing the injectors as well?
I have read through Ian Series 1's excellent post on his HG replacement and watched Gloucester Nige's videos on his rebuild dealing with the head which are very helpful, although both are 2.4 TDCi's and not 2.2's.
I plan on getting a genuine Ford HG and timing cover from our local Ford dealer (nearest LR one is 400km away). What brands would people recommend for the other ancillary stuff? noting that genuine head bolts are listed up at $30 each!!!!
Any pointers would be very helpful.
