Hello. Ive searched for this but I couldnt find anything too relevant. Alot on the 603 engine however.

My problem is, I have a loud "ticky" lifter that comes and goes, and its very annoying (to me anyways). Sometimes once its warm, it will go away, sometimes not. I really just want to replace all 10 of them and silence the ticks. I know that the camshaft has to come out. Can anyone tell me or point me in the right direction on the steps to do this? Im very mechanical, but is this something that should be left to the pro's? Ive never taken a cam out before. Im eager to tackle new jobs. Are there any special tools that are required. Any insight is GREATLY appreciated. A DIY would be great.

Also, how do you tell if the camshaft should be replaced? Visual inspection or is there a measurement?

Thanks for all the help!
