When I was doing my comparison of valve lifts I was turning the engine over using the starter motor, so hopefully the lifters would have not leaked down too much.

I guess my thinking behind just replacing the chain is that I'll avoid having to purchase another inlet manifold gasket (about $200NZ).

You can check out your engine like I've done (check timing chain slack, valve lift, compression etc.)and if it all looks reasonable go for the low-buck appro; /html/buick-rover-v8/1999-04/msg00011.html (8,451 bytes)

If the cam is replaced I've understood that replacing the valve springs as well is also a good idea. They're all part of the sam; /html/buick-rover-v8/1999-04/msg00013.html (8,834 bytes)

I basically agree that there is not much point in upgrading some of the engine as it will put undue pressure on the rest of it.

More on engines/cams (score: 1): Author: Simon Sparrow <Simon.Sparrow@wang.co.nz>; Date: Mon, 12 Apr 1999 13:07:57 +1200; Just to continue the saga, I've decided just to replace the timing chain in my engine (p76 V8) rather than do a top end overhaul. I figured out that a top end job (cam, heads re-con'ed) would cost a; /html/buick-rover-v8/1999-04/msg00026.html (7,403 bytes)

The Engine in my car is a Leyland P76 V8. I seem to recall that the Rover V8 starter motor can be a; /html/buick-rover-v8/1999-04/msg00056.html (7,333 bytes)

However I suspect my chances of getting an International Scout starter motor in NZ are even less likely than finding a P76 one. Does anyone know if this is a 'common' part?

The P76 is OK (I have one in my car) but its a bit of an orphan in terms of parts.

The std. P76 motor has a stroke of 3.5" and a rod length of 6.25" this gives a ratio of 1.78. The higher the r; /html/buick-rover-v8/1999-02/msg00017.html (9,935 bytes)
