It all depends whats been done and to what standard.
Generally drive it normally and there should be no issues, id just drive the way i always do no over revving or labouring and that's that. Maybe change the oil after a 1000 miles or so. How has it been rebuilt? I was under the impression that not much could be done to a Puma engine. Ie no oversize pistons available etc. If its just had new bearing shells Id just take it easy for a few days, it should be fine. Jono |

Mineral oil for say 500- 1000 miles then a change to fully synthetic and drive it like a transit!

If the head has been off, might be an idea to retorque the head bolts after a wee while???
At least that is what was recommended on my old series 3 2.25D when I rebuilt that 3 years ago, dunno about these new fangled engines, they may use new fangled bolts and head gaskets so it might not be an issue. Have the Pistons and rods been out? Crank and main bearings? Just drive it normally would be the best idea, don't thrash it or labour it, don't leave it idling for a long periods and give it work to do, don't leave it sitting at the same revs for ages, try to vary your revs a bit. If you want to be ultra careful you could always give it an oil change after a wee while to check for debris, signs of abnormal wear post overhaul. Would definitely be advisable to keep a close eye on the drive for any new abnormal leaks, and your fluid levels too. |

the new engines uses to "close" the head with angular method (=calculated elongation of the bolt near to the yielding point) so you not only do not need to re-torque, but doing so is counterproductive to do. At every disassembly of the head (loosening bolts) the bolts must be replaced with new ones Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition
