Just after fitting a new rebuilt 2,7 M20 but it uses about a litre of oil every 1000km. Previous engine was a 2.5 with 144k & never used a drop. Definately no leaks so just wondering what could be the problem or was the engine badly built?
Re: Oil Usage M20 If you can't see any obvious drip's or runn's any where, and there is no smoke out the back. then could be leakingin to the gear box bell houseing.
Do a gasket test before anything else though.

Re: Oil Usage M20 if its leaking into the gearbox take the cover off the forms part of the mounting point for the gearbox it had 4 13mm head bolts facing the tarmac and about 4 star headed bolts going through the gearbox
Re: Oil Usage M20 Confident that it is run in properly, crap oil, etc. There is no oil visable anywhere, if its leaking to the bellhousing would it be dripping from there?
Re: Oil Usage M20 if it was leaking into the bell housing it would drip out the slot at the bottom (unless its blocked)but then the clutch would be affected,
a litre of oil every 1000k is a quite a lot,
i only suspect its burning it but you say it doesnt smoke,
does it run how it should?
