Thread: Disco 3 Motor Options

After reading what I wrote in later emails I can see why you are getting confused over what I meant, when I said the change over at $10k was to much and when I referred to others having had it done for $5-6k.

You took it that I had included the engine for $5-6k which I had not. I was merely talking about the labour and extras etc like belts, hoses etc. The price's you are quoting if you did the change over are very reasonable to say the least and backs up what I was saying that the quote he got for $10k for the labour (change over) was to much.

Ah ok fair call, now the prices look about right. honestly I do think there are engine change jobs I dont get simply because what I am quoting and someone else is quoting, is two different things.

Ive not done a "on the cheap" change yet, for me, when its a $40k to say $60K of Range Rover, everything gets checked and replaced as required.
For some oddness i have, I've started taking pictures of these jobs.

Eventually the D3 will become an option for a quick cheap change. I wouldnt mind doing a few straight cheap change overs as there is a huge amount of time involved in stripping ancillary parts, cleaning and fitting. But hrmm then again....

I have some pics of the Chain failure. It is interesting to note that the failure was on a single hardened link pin and it looks like at a joint link or a timing point as the link is an anodized blue color.
From my observations I am of the belief that the pin ultimately failed after a progressive stress fracture which may of existed for some time and possible relates to the manufacture process (heat treatment etc) Disco3 IMG_6039.jpg

Yes Don, those colored links are timing links to time the cams. I guess there will always be just random failures- you see it on all makes- maybe LR owners are more social and sharing!!. We are just about to lift the body on our second D3 to do an engine swap. My original moter - with only 75K on it - had the HT bolt which holds the timing belt tensioner fail in Oct after I replaced the belt and tensioner in May!! I put a new fully dressed engine in mine -EU4 spec- with new injectors, turbo and EGR's. Just finished rebuilding my original motor with some heads I got from Dazza afterwards and about to put it in another D3 I bought with a stuffed motor- as yet undiagnosed but maybe seized or hydraulic lock. Reports were it was due to bad fuel!!! Anyway, can confirm Dazzas thoughts- lifting the body is the only way to go and gives you the chance to deal with other hard to get at items ie rear upper suspension arms. I am lucky I belong to an enthusiast club which has a workshop, hoist, engine stands etc available so quite do-able if you have the time and inclination.
