Default do i need to replace my cam or will li be ok

Hey guys i just pulled my head off and foudn that my lifter fell apart. and when this happend the spring that holds it all togther must have fell down and knicked up my cam a little bit but not to bad...Now honestly if i replace the lifter will i be fine or should i replace the cam. The reason why i ask is because right now i do not have a lot of dough and i need to get my car back on the road...i know it is hard to say without seeing it but give me your input...thanks

Well you can install another lifter and call it a day,however without taking the cam out it's going to be hard to judge how bad the cam is damaged. You lucked out this time, but next time it could cause your piston and valve to make sweet sweet love.

Well, if the surface is bad, it may chew up the new lifter and send **** all throughout the engine. I would at least take the cam out to look at it; maybe hit it with some emery cloth or something.

Pull it out and inspect it. I had a similar problem when a lifter broke on my old setup. I polished the lobe and it was fine. You dont want to be pulling the motor down the road for a complete rebuild because of a lifter. If metal shavings get in the bottom end it will score the crank and destroy the bearings. It can get expensive.

What exactly happened to the lifter? You might wanna investigate that so it doesnt happen again.

This motor was put back togather and within 6K miles, the new lifters were all torn up. The lighting in this pic makes the pitting look worse than it actually was.

If that was directed at my pic, it was one of the bad batch cams and it was [eventually] replaced.

To sum up, If you try and reuse a bad cam, expect to have to pull the heads again. You might make it 1000 miles, you might make it 15K, but chances are whatever killed your first lifter will kill again, and so will the pitting.

i dont know how the lifter came apart...the clip came off and i believe the clip is now sitting in the oiiil pan because i ran the car for quite a long time and the rest of the parts were in the plastic cup. What do you guys think could have caused this problem to happen...i want dont want this happen again. So should i just pull the cam out and put a new one in or rip the whole engine apart?

How does the lifter come apart with a pushrod on top of it? Unless the roller broke.

the motor is stock, it started tickin about a month before this problem but that might of been a exhaust leak i was hearin because i had new exhaust put on... do you guys think my bent push rod broke the lifter or the lifter came apart and then the push rod bent...
