Title: Disco 3.5v8 engine cracked what are my options
Post by: stevepage3 on January 17, 2010, 12:38:20: Ok

After the snow has finally gone, I thought I would go out and start my Disco, only to discover that there was no water in the radiator
filled it up and noticed water dripping from the bottom of the engine, I hoped it was going to be something simple like a core plug but
unfortunatley I found a crack in the block about 0.5inch long.

What are my options if I have any !!.

Could this be welded ?
Complete engine transplant and if so does anyone have a 3.5 v8 efi engine lying around looking for a new home.

I have seen a product from Holts wondarweld has anybody used it of know if this might be an option

PM me if you're interested and I'll let you have his mobile no.

Post by: Range Rover Blues on January 18, 2010, 00:44:50: The EFi heads are better, plus they have a cut-out for the spray pattern. The EFi had a bit more go than the carb model, better emisssions etc too.

You could swap the heads over without problem.

A V8 weighs about as much as a 2.0l Pinto, maybe a tad more. There are 8 bolts on the bellhousing and 2 are a swine to reach, so nothing unusual there ;)

It's just big, getting the clutch to line up made me swear, a lot :evil:

Worth putting a new clutch in obviously, I got the flywheel skimmed too to get rid of the crazing.

Post by: stevepage3 on January 18, 2010, 09:28:48: I have already done the clutch so that should save a bit of time.

What about electrical, is it just a case of unplugging the loom from the bulkhead and
plugging back in once the new engine is in place.
