Camshaft Wear
Stripped down the pinto yesterday and I would appreciate some info on the cam please 
I'm not sure of the mileage, but the big end and main journal shells are in lovely condition so I am guessing it's not done astronomical
miles. The bores are fine and the pistons too. My main concern is the reputation pinto's have for eating camshafts! There is a very small lip on
some cam lobes but I certainly wouldn't say it's BIG. I know that the case hardening isn't very deep but are there any tell tale
signs of too much wear? (without listening to the enine running  )
Anyone know what is acceptable?
Cheers,
JB

If there is any lip on the cam at all it's worn - I wouldn't use it.
It may well run but it won't last a huge length of time longer and it will be noisy and get noisier.
Change it for a fast road cam and enjoy better performance.

As mookaloid says the cam profiles (and followers) should be completely smooth. Any ridges around the nose of the lobe means the cam is worn out.

Are you considering any tuning work on the engine? If so your choice of cam will depend on the amount of tuning you are doing.
If you are keeping everything as standard then just go for a Kent FR31 or FR32 or the piper equivalent.
You will need new followers with the new cam and there is a running in procedure which you need to follow - the instructions will come with the
cam.
Maybe something like
this cam with
these followers
and some cam lube for the running in.
Cheers

Cam wear is not signified by just the cam wearing, but also by wear on the followers/fingers. Their should be no lip/wear on either.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

There is not a cheap option as such, i may have a cheap standard cam but you should still use new followers, about £20 to £30 on ebay, you still need
to use the Lube and fit new bearings as the old ones wont fit.
I sugest you save up for a new cam kit and run the one you have at the moment.
There are some auto jumble bargins to be found if you look.
I got a brand new Vernier pully mated to an RL2 cam for £30 so just need springs and followers.
Unless you go for very high lift long duration cams the standard followers are good enough, perhaps a bit of weight balancing with a dremil.

Thanks for all the input guys. I really don't have the funds to get a new cam and followers although I'd like to get a Fast Road cam to
squeeze a little more from my mundane 1.6  (not sure how much extra it would give?).
The wear really does seem slight and I think my best option is as already suggested, to refit the cam as is and run it until I can afford a new
one.

Why won't the old cam bearings fit?

The cam is slightly worn by the sounds of it but not excessive, obviously get new when you can, but just keep an eye on the lobes. when you start
seeing lines on the running surface on the lobes like scratches that is time to get it out as swarf will be coming of off it and you dont wont that
floating around the engine. i use to work for ford as a mechanic so anytime i an help i will.......and when you change cam be sure to get the kit
ie cam+followers
