Thank you for finding those for me
Dad is nto keen on putting more cash (other than gaskets, studs, etc this time) into the 300tdi motor. His original plan while he owned my ute was to eventually swap it over to V8 on gas, but entirely on gas with bigger tanks so it didnt matter what V8 we put into it. He wasnt sure how he was going to go about this, but would anyone here have an idea? Becasue if Im already going to have to get a loan out to buy a new vehicle, Id rather punch the money into putting a new engine into the Defender and getting my 300tdi woes over with. Dad thought it would be around 4 or 5 thousand just for the gas system, but then we have to sort out the engine.
Does anyonehave any suggestions about this and is it a worthwhile plan?

Seeing as you don't live in Peat's Ridge anymore, is LPG easily available on your usual coupla hundred km treks?
Get your head checked before spending too much, it may be okay and its only a gasket needed.

Hi I overheated my 300TDI, and did no damage. do not expect the worst until you have the head off.

overheated 300tdi plus question on plug

Just looked at the head, it isnt warped actually theres no damage at all to the bloody engine..... it still starts and runs fine. We are going to put a new Elring gasket on, and hope that solves the issue for now. We are also replacing the head bolts as Dad thinks they are a bit shot now, the heads only been off once before but the bolts are a bit shoddy.

And we can still get LPG at our local servo (45km away), but if its not working we have to go another 150km to get it lol.

I would like to look into doing the V8/LPG idea, and then if the ute runs fine after we have put the new gasket on then I will keep the V8 idea on the books as a in the future idea.

W have been told that for everything to work correctly this time around, we need to get the head machined... im sure that wont be cheap... bloody landrover is sending me into the poorhouse lol but its worth it if she works how she should again.

A good machine shop should be able to reface it for less than $150, and that should be returned to you in a clean ready to bolt on condition.

Always blow out all the ports and galleries yourself though, just in case

They are a fantastic simple engine, I wouldn't swap it out for a V8 petrol engine, especially on gas.

Diesels rock.

the last time I did a total rebuild (at cash mates rates not beer rates) for a tdi300 with the owner doing the runaround and organising the parts he was instructed to buy he got change from $3k for a complete rebuilt engine using his old engine and replacing pistons, rods, bearings, head (complete), pumps, (not the IP)mounts and reworking the radiator.

he then decided to fork out for a new clutch assembly which ment he had to get a new flywheel, the old one cracked during refacing.

if the bottom ends ok you can replace the head for less than $1k.
