Thread: disco 4 engine

I hope you did your research before acquiring your vehicle. Around 2% failure of these engines. Very expensive to fix.

Have you read these threads?:

Engine Failure on 3.0lt SDV6 help.

D4 3.0 SDV6 catastrophic failure

Almost guaranteed you have a snapped crank, they snap at no.2 journal so the front will rotate but nothing else.
I hope it was very cheap.

If its a 2.7 put in a Ford Territory engine
Plenty of info on this site

What did you pay for this plum is the key question here.

I as intending to remove the sump and inspect but that looks a pretty serious so i was wondering if anyone could offer any information regarding this. Thanks.

You can buy the workshop manual online from the aulro website. Should have what you want in it. I believe you need to pull the front diff to get the sump off. I was thinking about doing a bearing roll in my 3.0L.

If your worried about a crank, pull the starter out so you can see the flywheel. Then rotate the front balancer. Hopefully you don't see any free play between the two. Are you turning it from the front or rear at the moment

As a 3L owner I like to be optimistic. I love a good success story.. Hopefully he doesn't need that book. I feel he will need more then my optimism but.
