Used to do this with WRX STI's but multi novas and impound yards cause old men to buy LandRovers

That's great DB.. Hopefully it's all good for you now .

I will get the patch next month at service because, mutch to the horrer of some people, I am happy with my Puma, unhappy with electricians

The patch seems to provide a heap of extra mid range grunt - and is quieter on cold startups.

Good to hear the dealer is now treating you well and let's cross everything that your vehicle is all sorted.

Why not take a scenic trip to Melbourne via the Snowys or something? Plenty of variable speed driving.

Incidentally, the manual's directions regarding running-in are interesting. The technique they use at the LR factory when each vehicle is completed is they put it on a rolling road and flog the guts out of it for a couple of minutes. Then they jam on the brakes and the vehicles lurch and jump around like they're about to break their shackles. Then they drive them out and stick them in the holding yards.

Sounds like a perfect job for a teenager!

Glad to hear it's sorted at last.

When I drove yours I noticed that the clutch engaged high in the pedal travel compared with mine. Has this changed with the new clutch.

Good that the sky is now blue.

Hi Mahn

Ian seems to think it is lower......I don't know whether you guys had yours changed with the clutch or not but we also got a new slave cylinder

I'm a bit concerned with sythetic oils as regards to new engines also,the last thing a new engine needs is friction reducing oils.Just drive it and enjoy it.The puma might have less performance when cold because it is running retard timing to stop the knock. Pat

to be honest pat it will be interesting to see...because I think the car towards the end lost a lot of performance full stop...it just didn't seem to pull in third like it used to. So once we have worked and loosened stuff up it will be interesting to see whether we notice any improvement

Years ago when I raced motorcycles and the engine had cast iron piston rings, they could be run in quickly by alternating power on for a short time up a hill, then right off down hill.

The theory was, with power on the higher cylinder pressure pushes the compression rings out to the cylinder bore harder, then power off, the throttle is closed and there is vacuum in the cylinder which helps with getting lubricating oil to the upper surfaces of the cylinder and rings.

But these days hard chromed piston rings and cylinder bores are often used in engine and they take a very log time if ever to 'wear-in' (especially with friction reducing oil additives).

In these cases it is mainly the cam lobes/tappets and crank bearings that are being run in. And I would follow the light power on, followed by power right off (so oil film thickness in the bearing can build up).
