hello everyone.
look at this camshaft, should i replace it? it is worn but not extremely.

 

if it's worn replace it.
have you mesured the lift on the lobes and compared them with each other?
if not, get a caliper out and measure them, if it's only the tiniest amount of variance you should be ok, but approaching 0.1mm is quite bad and will make some cylinders run leaner/richer than others.

 

no i haven't measure them. will do.
thanks for the advice!

 

lmao!! If you can see any wear then bin it!! The lifters will be worn also and so you'll be well down on power.
Make sure you change them together and run them in properly to have any chance of survival.

 

looks like there is no lobe left on the left hand side first pic,that will be number four cylinder i bet.

 

As above, to me it looks pretty well worn tbh, i've binned cams that looked no worse than that!
