Thread: Dreaded loose liner, would you go 5 liter?

How about the 4.8L option.
Or stick with the standard engine and just get a towing cam fitted.
Might be worth getting the heads CCd and port matched with an emphasis on bottom end torque.
If you have been looking after your trans since new i would say that it will hold out ok.
I had mine on a dyno 9 months ago wish i had done it years ago, i picked up 5Kw, doesnt sound much but it was noticeable.
If you could pick up say 15-20Kw i think the 38 would be an even better thing.
Radiator at the age of yours perhaps get a new one (stock)$400 well spent i would say. I replaced mine last year (95 mod) as i had the smallest of leaks from the expansion tank hose. In 12 years i have never had any over heating issues at all. But having said this i popped the tanks off my old one and it was clean as a whistle bar 2 tubes 1 blocked the other partially.
Perhaps some exhaust changes are a good way to get some more power.

No substitiute for cubes in a petrol if you are towing,,
price a new full alloy rad,,


I've come to the conclusion there really is no comparison to a turbo diesel when towing,,
600nm cant be wrong,,
the 600 will cost you 100K though

did I say that out loud?

Thanks Gary,
very interesting and useful, much appreciated.

I'm v impressed by the Turner website, above, and in particular the care which they take in building their product. Of course, where possible I'd prefer to buy Australian and I wonder whether any of our local engine builders approach those standards?

You can always talk to Triumph Rover Spares, they have a range of options available:

Yes they reckon they ar enow wWorld leaders in large capacity Rover engines, but I think their emphasis is on racing engines not day to day drivers in 4WDs. I can remember a couple of years ago the unhappiness of one poster who had followed their cam recommendation and was unhappy with the loss of torque.

I noted in markets a while ago someone was selling a 5 litre engine and the seller noted that the forged pistons were really noisy when cold.

What you want in a 4WD is a mild engine with good manners built to last a long time between teardowns and one which is quiet and civilised, probably with cast pistons and close clearances and a moderate compression ration of low to mid eights if 91 octane is to be used.

I don't know if this is available. But you want to ask a lot of questions , seeing these are not factory build type motors.

When the engine is stripped down and the liners seem to be in their correct position - how do you tell if there is a slipped liner. I have a lead on a short engine but its condition cannot be verified.

A while ago someone posted a video of a V8 block being warmed on a gas BBQ. Once the block was warm enough (checked using an infra red thermometer) the liners could be removed with little effort, using only hand force in a welding glove.
