Think I know the reason this Rover 75 1.8t was scrapped.

Saw this car soon after it had arrived a couple of weeks ago. It had the PRT ( Pressure Relief Thermostat ) and as I needed that assembly for my ZT 1.8t which does not have it. Whilst removing that I checked the condition of the Turbocharger and there was little play in the turbine shaft either end so decided to have that too. I do not think the Turbocharger was the original judging by its appearance and the fact that the Exhaust Manifold to Turbocharger Flange mounting nuts and studs were not the originals. In fact a bolt was used and all the nuts were poor quality hex-nuts ( six flats ), not the better quality original bi-hex original fitments.



As on the previous visit I had removed so much stuff, Cylinder Head removal on this car would not take long so I returned this afternoon. I do not think this Cylinder Head had been removed since the car left the factory. Several signs confirming this. Soon had it removed.











The coolant pipe PEP 102160 which runs behind and around the engine and over the bellhousing was obviously new and fitted recently.











The Thermostat housing contained a new Thermostat ... the car had a PRT fitted ... Hmmm.







PEP 102160 should be secured with two 10mm Bolts. It has two strong brackets for the purpose. Only one contained a Bolt! At least one of the 13mm Nuts securing the plastic Inlet Manifold to the Cylinder Head was missing. Several were only finger tight. Most of these are difficult to access and the one missing was the most difficult to access. Also, only one was the better quality original nut the car would have left the production line with.



Removal of the Inlet Manifold would be the best way to fit that new Coolant Pipe.



So, based on these observations, whoever fitted that new coolant pipe, be they amateur or pro were lazy or not very thorough. Maybe both.



The car showed no signs of cylinder head gasket damage but, surely TWO Thermostats would lead to overheating and that I feel is the reason this half decent, relatively low mileage car met a premature end. The latest and current MoT ( Expires Oct. 2014 ) was present in the car which I used to check the MoT history on VOSA. No worries there.



Closer inspection of the Cylinder Head showed it has never been skimmed. Bonus. I'd bet it has not been off the engine since the car left the production line based on my checks. Delighted with it.
