I got some Gsr cams with some cam gears, the cams have rough demage from the cam caps being too tight here are some pics, are they worth fixing.. I plan on using them on my b16a. Only the intake one has the most demage.

 

we can barely see the picture..

 

Im learning...

 

That looks like aluminum has been galled onto the surfaces. A micropolish should clean them up fine.

 

a micro polish can fix them will they fit fine on my b16?? Doesn't that remove material?

 

you can feel some rough lines thought can It still be fixed>??
who can fix these for me

 

let me ask my boy he might just give you his if you pay shipping

 

If the bearing journals are scored you can have them built up by welding and re-ground. The lobes are OK right?

 

yes

 

Micro-polishing does NOT remove material. It will not make those look any better.

 

So are these cams worth the micro polish?

 

They are only gsr cams. Don't put them in a perfectly good head and risk damage. Micro polish is for crank journals final finish not removing galled up aluminum and scratches

This is your only option. But its more expensive than its worth. Buy another set of GSR cams. These are worthless, unless you have a good hookup to get the regrind done.

 

normally what is the cost to regrind them

 

Well i took them to get cleaned up and there is still some scratches lines a little rough I decided not a to risk my head

Good move

 

I dont know man they are smooth but you can feel lines, the machinist said it should be ok he said those lines will help it oil better. Yay or Nah?
I really dont have money for some real cams right now.

 

Cams are pretty forgiving when it comes to journal damage. I'd use those, but it's just me. The cam I'm running now has some grooves, but it's not as bad as the one in the above pics.

 

im gonna install them, and see what happens

With the price of undamaged GS-R cams being so low, why risk running these?

 

Really, what's the risk? It's not going to sieze because of the grooves.

Not necessarily, no. However, if the remaining damage on the cams is sufficient, it could in turn cause damage to journals. With undamaged GS-R cams being available for less than $100, why chance using the damaged ones?
