If you are rebuilding an engine, then replacing piston rings goes hand in hand with replacing liners, gaskets kits top and bottom, oil pump for sure, mains and big ends but then would it be wise to regrind the crank? Yep. Water pump definately, all belts, head skim, valve regrind, probably get everything dipped to clean all the shite off. New cambelt tensioner, dizzy, rotor and leads, plugs, oil and other consumables. Then add the new turbo, clutch and fly centre bearing, of course a new rad to protect your investment and coolant pipes? dare you risk a full rebuild on old pipes?
It's false economy to put a new engine in without making sure the coolant pipes and rad are in first class order.
i know it adds ?500 approx to the build but its protecting your investment in the long run. if one belt breaks one pipe lets go it could kill the time and money already put in.
I was lucky enough to have a couple of mates put my engine box in for me but even so by the time i had put new fluids top end gaskets etc etc the cost soon mounts up by another couple of hundred Squid but then my engine has run faulessly since it has been back in apart from the existing alternator blowing and the heater matrix and an Amal valve the engine itself has not missed a beat :wink:
All i can say is that it was well worth it
and as the quote below states
WHERE DOES IT END?
