Thread: Disco engine meltdown

Im soooooooooo glad i got rid of the D2TD5 i had ....

And really happy I have a 300tdi in my Rangie 8) 8) 8) 8) 8) 8)


Sorry to hear about your drama's mate ......Dave Purcell of Britt Parts and Service center said and i quote ...."I DON'T TRUST THE TD5 , they are sealed boxes of trouble in waiting"

That's harsh!

Sorry if that sounded harsh ops: just after my 5 weeks of TD5 hell im over them


Your right but in this day and age of technology it is appaling , esp when Nissans 3.0 melt down , Toyota's front end falls apart , Nissan's 5th gear failure ....everything Jeep .....ect ect

once agin if i have offended im sorry :wink:

Are you sure it was a Td5???

Unless you have prior knowledge, I do not find any reference to a diesel.
I also thought the Td5 motor was generally reliable :wink: :wink:

Cheers,
Lyndon.

BRS has vented spleen and I hope he or she feels better now...(and Sith :wink: )

Hardly a meltdown.

The roads are crowded with Discos and I can't remember the last time I saw one stranded (apart from mine :wink: )

Who ever mentioned the TD5 to start with :roll:


Now Pedro how you feeling :wink:

Ahem. He says V8.
This is a well known problem with the latest V8s.

It is almost always an exhaust valve which sticks due to hard carbon accumulating on the valve stem, not really insufficient oil.
The 4.0 /4.6 was the first V8 to have teflon type seals on the exhaust valves which reduces the oil consumption, and they have oil impregnated valve guides ( which do not work too well)
Fixes
More common on engines which are not worked hard, so give her a long trip every now and then.
Less a problem when synthetic oil used, eg Mobil 1
Maybe injector /chamber cleaner but whether this cleans exhaust valve stems is debatable.

When its rebuilt get them to delete the seals on the exhaust valve guides and just use umbrella seals.
I have rebuilt my 3.9 heads with a teflon seal on the inlet and no seal on the exhaust ( as the vacuum is on the inlet stem). Oil consumption of Mobil 1 is about 500 CC per 5,000KM, which I think is acceptable.

Better than a stuck valve anyway.

By the way even my 3.9 heads when they came off at 100,000KM had a couple of exhaust valves which were a bit iffy, not stuck but not free either, so it affects even older models

Mine's got a noticeable tappet tick that no "Technician" can find. Forgot to mention it to MR Autos but now I'm worried!

PS, if you live in Brisbane and have Rover product, I recommend the boys at MR very highly.

Any hint of that tappet tick in the trouble list?
