I have looked for a compiled list of parts needed when buying a turner tophat linered block. Thinking about rebuilding a 4.6. Should I reuse old pistons etc. Just want to see how much depth or detail the rover guys go to upon rebuilding? Anyone upgrading cams? I know how to rebuild engines just wondering at what point on parts you stop and use the old stuff from the knocking engine or at what point you by new? A list of a typical parts for Disco 2 rebuild would be nice, search but cant seem to find is list.

Thanks

 

How do you know you slipped a sleeve, how did you test for it? Who is going to do the work?

 

Call these guys.
D&D Fabrications: Engineering & Fabrication Services
They have everything from different cams to rods to you name it.
Tell them what the problem is and what you want to do.

 

He is talking about buying my D2 and building my 4.6 that came out.

 

Most engine rebuilds would include new pistons, but on these 4.6L engines, the pistons are about $100 each. I'd have the machine shop measure the pistons and their clearance in the bore, and only replace them if they are out of spec.

Have them measure the crank, and buy bearings based on how much they have to machine it.

Replace the cam and lifters for sure and probably the rockers and rocker shafts, if they show signs of wear.

 

The pistons in a 4.6 which runs well other than a loose liner, will almost always be fit for future service. You don't need to measure them - that is the job of the guy who will hone your block to suit the pistons. All you need to do is visually inspect them and see if something obvious is amiss, like seriously scuffed skirts, crown and ring lands are in good condition, etc. Also check the little-end isn't binding or seized or worn.

Basically, if you can see/feel the machined finish all the way around the piston, and there is no play in the wrist pin, it is suitable for use.

Search for posts by my username. I rebuilt my 4.6 with a replacement block, and have posted parts and costs.

I also wouldn't personally bother with anything other than the stock 4.6 cam. Myself and others who have rebuilt their engines, including having the valve-seats re-cut have noticed a huge chunk of extra power than before - I'm not overestimating when I say my disco is now plenty quick enough for the chassis and brakes on the roads around here.

 

Ok, the post was on a different, but almost identical forum...

How are the new liners put in?
Is the block heated up and the old liners removed first?
