Latest update for the car is that ive started an engine rebuild.
The car has been blowing smoke for a while, we did the valve stem seals first which didnt fix the problem.
Had the car at sandown and after one session it developed a rattle and seemed to loose power.
Managed to limp it home doing 80kph, been sending free time since then taking it apart and getting things checked out.



Found one of the big end bearings had allot of wear and all the oil rings had lost tension. Looks like the engine had not been apart before for doing 260k was in good condition, no damage done to the crank or bores which was good.
Got the head reconditioned:
Before


Reconditioned


Inlet cleaned of oil build up


Also had injectors serviced, starter motor and radiator reconditioned
