Les Henson Posted January 13, 2009 Share Posted January 13, 2009 I would imagine that the crack was on the exhaust side of the head to the coolant. Lots of pressure to prevent water escaping while at high revs, but at tickover considerably less, so water then leaks into the exhaust system. Just a theory really. Les.

Sounds like a good explanation to me and perfectly plausible. DaveJ Quote Link to comment Share on other sites More sharing options...
pinkbeef Posted February 23, 2009 Author Share Posted February 23, 2009 Ok, The final result is in and it has now passed the MOT with no faults. So it looks like the head was cracked, as the steam did clear up soon after fitting the reconditioned head. All in all now I know what im looking for, the 1.8 petrol head gasket change is not that bad. Next time ill just follow this plan: 1 Clean engine. 2 Remove head and clean mating surfaces. 3 Check hight of liners, if low in the block just replace engine. GO TO 10. 4 Have head tested for cracks, if cracked or damaged replace. Otherwise recondition the head. 5 Use break cleaner between piston and liner and vibrate the piston in the liner, to losean off any stuck rings which may be gummed up with oil/water mix. 6 Remove sump clean out old oil, renew oil filter and oil. renew the oil rail, replace sump. 7 Renew water pump remove rear thermostat, replace with thermostat mod. 8 Renew timing belt 9 Renew head gasket with the steel shim type, replace plastic dowells with metal ones, use new head bolts if required. 10 Finished. A bit overkill, but for the extra cost, "I think well worth it". A big "THANK YOU" to all for the input and answers. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted February 23, 2009 Share Posted February 23, 2009 BODGE ^^^ Flush cooling system Drain/flush engine oil Bleed system 20-times to be on the safe side. For the next 6-weeks, pay unnatural attention to the temp guage/water level/funny noises/how easily it starts/did you forget something/fuel consumption/oil level/colour. Have nightmares about the engine. Seriously consider buying a Pajero. Have an Unnatural desire to join a Freelander-related religious sect.
