Advice on purchasing a high milage 300tdi

Hi everyone, I'm currently looking at purchasing a 110 with a high milage 300tdi engine in it. Close to 200,000miles.

In terms of the body I think I have a relatively good handle of what goes wrong, but in terms of the drivetrain and engine I'm a uneducated.

I'm wondering what peoples thoughts are on this? What should I be checking? Should I be getting a compression test? What's likely to go wrong with it in the future and when things do go wrong (head gasket etc) can it be re-built to do another 200000miles or are you better off buying a lower milage used engine?

Any advice would be greatly appreciated.


Will

If maintained conscientiously these engines have a long life. If it has a good service history you can expect another 100K to 150K more miles from that engine as is, before a rebuild would be needed. Most important thing is to know whether and when the timing belt was changed. If not absolutely sure, budget a few hundred dollars to have that done ASAP.

Gearbox of course can and will go sooner, clutch too. But those are easily fixed.

Andrew Hutton (Offroad 101) is local to you in Ottawa (well, he's in Kanata). He knows a lot about the 300Tdi and runs one himself, on biodiesel that he also manufactures himself. He'd be good to call to have him look over your potential purchase.

my experience has been that the 300 engine will probably be fine @ that mileage but the r380 won't

I can't imagine that it would be the original trans with that mileage so it might be ok if replaced. I have run a 300 well int 300k miles with no issues, still original IP and not exactly babied. In fact Id say its been very well abused but maintained as it should be. Had to replace pretty much every gasket at least once but most seemed to co ordinate with other issues…..like every time I've replaced the clutch the rear main seal gets replaced. Common sense stuff. That and the "right stuff' (?) gasket maker should become your friend. I've replace the timing belt every 50k as recommended by the book for engines that are subjected to abnormally hard use. Injectors are only optimal for about that same mileage IMO which is shared by the local injection shop specialist, however they will go much longer if you are lucky enough to always have great fuel. Much of the issues with pumps and injectors that I see are due to poorly produced biofuel so beware of that, as in previous use, and if you intend to go down that road don't depend on the factory filter, and get a water alarm…….as mentioned, Mr Hutton is on the game in your locale, so definitely look him up.

Thanks for info everyone. Andrew doesn't live too far from me and I've been out to his shop once this past year, so maybe I should give him a ring.

The R380 was rebuilt in the last year so hopefully that will be ok for a bit.

The truck is overseas and I would be importing it, and I'm starting to think it might make sense to pick up a lower mileage engine at the same time to either rebuild or just keep it as a spare for when the one in the truck gives up.

Ultimately I would like to build up a rolling chassis (on a new galvy frame) over the course of a few years then drop the top on it. I'm hoping in the meantime this truck would be a runner while I'm doing that. Of course I know anything could happen, but it's sounding like I can get some time out of the current engine to let me do that.
