OK, you can do an oil pressure test this will give you a fair indication as to the condition of mail 7 big end bearings, you can also have the oil tested, this will give a better idea as to the amount of metal (bearings) in the oil, with the mileage you have there is a chance that if you do the head only you may start to burn some oil, this is due to the higher compressions as a result of the now fully sealed top end. A fulley re coed engine is of course the best way to go if you want many more years of service, you can also do a part re build, rings bearings oil pump & head, but this can have a few problems in the longer term as bores and crank are not re machined, this is a popular option if the core of the engine is deemed to be suitable for this minor re build, major components will have to be measured and still meet specs, this will normally result in a serviceable engine for some time, but obviously not as long as a fully re co, cost may come into your calculations, and the viability of the rest of the car, you must ask your self, do I want to be driving this car in 3-5-10 years time?
Doing the engine is no guarantee that other major items diff, trans etc will last the same time, another consideration, do the engine and in 1-2 year the trans dies, it may or may not. But you must consider this as a possibility, if by now you are thinking get rid of it and up date, that may be a wise option, but you have to make the decision on cost, and what you want in the next 3-6 year min,
