Cam ware

[AJC]

Hi
I am in the middle of a bit of work on my griff 500 and as the engine is out decided to check the cam for ware. I started a bit of rough measurement checking from one lifter to the next as doing this the valley gasket is also off so a visual of the cam is also possible. It's probably worn across the lot as the car has done 50000 miles but one of the lobes on number 5 cylinder has a lot more ware probably half the lift of the rest this is obvious to see when you look at the cam. Should I be looking for a reason for this before I put a new cam in?
Any help appreciated

Cam ware on our engines is a common issue and can become apparent from around 20000 miles onwards, I'm sure I've read somewhere that this is compounded by double valve springs but I'm sure someone with far more knowledge than me will be along soon to offer further advice.

Good luck

Yes, cam wear is a very typical feature of the Rover engine. It's also true that engines with quite severe wear can appear to be running very well. In summary, don't worry too much about it.

But do change both cam and lifters as a failing camshaft and lifters will shed its metal material into the oil and all round the internal oil-ways oil filters can only stop so much more expense
