Discovery 2a V8 SE advice

**sippahodge** · 21st July 2021, 07:53 AM

Hi All,

I'm new to this forum and this will be my first post outside of my introduction post. I am looking for a Discovery or RR from D2a to D4. I missed out on a D2a HSE v8 I think was owned by a forum member but another one has come up for sale.

It is a 2003 SE V8 with 128k km. My reading and research has indicated to me it is only a matter of time, if it hasn't already, before the liners will slip in the rover V8 requiring a Top Hat liner short block as a permanent fix.

For those of you who have done the Top Hat engine would you do it again?

What sort of money were you up for? Triumph Rover Spares has a bare block listed for $2950

Would you consider a LS engine swap as an alternative? Has someone here done an LS swap? Have seen LS engine, tranny and all associated parts required for a conversion without adaptor plates and mounts listed around the $6000. I think you can buy almost everything else off the shelf from LRA and Marks 4x4.

Failing this I'd probably try and find a 2.7l D4 or TDV8 RR. What you all think?

You are probably correct as it is the operating temperature that causes the problem.

if you replaced it with a top hatted block, AND ran it at 88C the new engine would probably last "forever"

My 91 RRC was going strong at 225KK as it had NEVER been overheated over 100C . Camshafts were another matter of course as the base diameter of the cam lobes is too small for them to last a long time.

Fit a low coolant alarm. The liners only slip if the motor has been overheated.

Are you telling me it can be avoided?

Liner slippage is the result of overheating. Keep the temperature within range and the liners wont move.

Do you think a 2.7l D4 is a better all round option for getting out with the family onto some islands and 4x4 camping? More reliable than a D2a? would use less fuel and probably a lot more comfortable?
