Outer Limits 4x4 Board

Totally new around here but i read somewhere that the Australian Lads had figured out a way to pin the 4 ltr. V-8 cylinder liners in place

My 1996 Discovery suffers from 2 droped liners, i know the engine is probably terminal but i'd like to hear more of the procedure if possible

the v8 petrol rovers have liners i find that news, maybe a diesel, if its dropped liners has it damaged heads or bottom end.

4.0 engines I don't think really suffer from that - more a problem with the 4.6's here

what do the rest of you reckon ?

Its a 96 disco so it has a 3.9 that was marketed as a 4ltr in the US where they thought bigger was better, generally was only the 4.6's but a lot of 4ltr's were repalced under warranty due to head gasket failures but i'm not aware if liner problems were to blame.

All Rover V8's have a tendancy to drop liners. I have seen them replaced, re-lined, tek screwed back into place etc.

I am sure there is a better fix than tek screws though.

G`day Dave ,

All Rover V8s can slip liners .

There are liners know as top hat liners .

They have a lip/ring on the top and the block deck is machined on the deck to accept it , the liner is also short enough that the base is able to sit on a machined surface in the bottom of the block .

As far as pinning liners there are many different ways of doing it but are really only relevant to the 3.5 because the 3.9s etc usually will have cracks in the block and pinning won`t cure the coolant problem .

All the best , Peter .

Thanks for all of your replys and especially peter r. , that was a very good discription of the overall droped liner problem....

I'm guessing the top hat liner route is the best fix.......
There are used 4 ltr engines out there, well out here, in North America but i suppose potentially any of them could drop a liner

Hmmmm back to the drawing board

Hi,

Put a Chev in it and forget about issues like dropped liners. A new 350 is about $1500US at K-Mart in the US isn't it?

As for the Chevy swap, for me iit's the only way to go: 350, 700R4, LT230, Toy centers. Heck, even a 4.3V6 will do.

You are quite correct 350's are a dime a dozen over here but unfortunately it's not quite that simple as just shoehorning a replacement 350 or 305 cu inch into a 1996 Disco.........

If anyone knows a simple way please tell all

PS; Thanks for the D-90 link on the subject..........

You can buy complete adaptor kits for the chev conversion in Aus for about $1000 aud.

But easy to fit.
