Damaged GSC S3 cam journals

[daniel Dee]

I brought the cams to RG they all agreed the Journals are toast. I then bought the cams to Shadbolt Cams and they measured the damaged journals at .003 deep. Overall the damaged cam journals measured were .006 less in diameter than the non damaged cam journal.







Delta Cams says they can spray welded/prep the journal surface @ $25 per journal.
These two journals are the worse of the bunch.

Anybody has any experience with this process?  Nobody seems to want to do this locally.

Whoa, those are some f**ked up journals. Did they came from your car?

If you have them welded up, make 100% sure the cams spin freely in the head.  Unless you have some junkyard motor, I wouldn't bother messing around with welded up cam journals.  There are already plenty of things that can go wrong with a high HP, high RPM stroker motor...

Yikes!  Paperweights now, or $1-$2 worth of scrap steel.

Did u buy them used? Or did they come out of your car?  I wonder what the journals in the head looked like!

[KevinBuckham]

Seems to be a rash of bad cam journals lately.  Either manufacturing problems or lots of people are having oiling issues.

I did my cam swap yesterday, the old HKS had a few scratches on the journals as well, but nothing that excessive.

[Brett Haviland]

seems like buying used performance parts off the net never seems to work out very well.

[Jordan Kruger]

Brett is completely right.   Its not the online thing that is bad though.   its damn near every seller on DSMtuners.  The truth is, about 13 out of 20 transactions Ive done with people over DSMtuners, resulted in me getting parts that are either broken or worn or dont match their description.
It would take some desperation for me to buy something from Tuners at this point.

Ill bet someone ran those cams with mismatched cam caps.

Fill out the form on his contact page.  Yes, I see no email address so you could attach your pictures.  You could paste the link to this forum thread in his contact us form... If anyone can make them work, Geoff can.  I think he's honest enough to tell you if the risk is too great to bother either.  He has a great reputation on other forums.

I agree with both Lowell and Richard on this one.

While I think Geoff at Colt can do great things and is the only one I would trust for this, I also know that even if you take stock cams and put mismatched, but factory spec cam caps and put them on the head, correctly torqued and lubed, you will probably still run into problems. the tolerances are tight and the "bearings" are just the aluminum of the caps and head.

IF Geoff says he can save them, and if you want to pull your head and have the caps line honed to match the cams, then go for it. if that's even possible.  if not, sounds like the end of the line for these ones.

[daniel Dee]

Colt cams says it will be possibly cost prohibitive.
I will bring my cams down to Delta cams for evaluation and possible repairs.
At the same time I will be picking up an new billet Kelford tX-280 profile..
If things work out I will have a GSC S3 cam for a spare.

[John Hartman]

if Geoff says its gonna cost too much to do it right, I would question Delta being able to do it right for much cheaper.  Keep in mind your gas costs and time as well.

Not to jacked the thread but Eddie am interested on those cams.
