Camshafts - ok?

[SRT41320]

I got these stage 2 cams for free off a friend... one cam (the intake IIRC) has 4 lobes that have knicks/gouges/etc whatever you want to call them from when he bent a couple of valves... im thinking about asking my machine shop guy if they are usable but figured id ask here first - would save me about $450 if they are usable


heres a couple pics - the worst marks IMO

Cams (when rounded off) make great lamps. Just saying... If you decide to use them for a side project.

im having a hard time remembering if those were like the older roller rocker/followers or whether those act directly on a tappet
from the wear it looks like a typical roller wear pattern as its not full across the face....

 

[Turbocharged400sbc]

ps ive run worse with roller lifters....

shit its easy enough to pull your valve/cam vcover for inspections id say run em

Take them to Opel Engineering in steemwood.. they fixed my cams before when shit was fucked up

cams directly touch the valves IIRC - hence why i dont think it would be a problem...

new cams are less than $500 - would it be worth it?

 

[Turbocharged400sbc]

no lash caps?

 

[SRT41320]

shit... yeah i think you;re right... been a while since i looked under the ol' valve cover lol

 

[Turbocharged400sbc]

if there are lash caps that those ride against and not directly on the valve stem then fuckit run em...at most they will wearout the caps which you can replace

 

[slow4.6]

I would ask when you take them there.. they did mine for 250.00

 

[SRT41320]

yeah ill have to ask... because if its going to be $250 then ill buy the bigger cams i really want for $450 - these would do fine in my car since they are free... but bigger is always better

 

[Turbocharged400sbc]

fuck man it looks like they are hydr lash adjusters with center roller rockers just like the old 2.2/2.5's
your fine run em

 

[Turbocharged400sbc]

your fuckin golden man

just rtv a couple magnets near drainback holes

 

[Turbocharged400sbc]

the rocker rollers will go right over those grooves without issue

just use a straightedge to make sure there arent any raised ridges on either side of the groove...if there is hit em once or twice with a flat bastard file

unlikely opel can do anything with cast iron cams except regrind with a smaller base circle

didnt think about that.. the cams I had them fix where billet

 

[Turbocharged400sbc]

only thing workable with cast is plasma/powder welding and it would be about the same cost as new one's

did those come off a car that broke the 3 groove valves? i worked on a 2.4 a while back that dropped a valve when the fucker broke

 

[Breze84]

It should be fine... I personally would buy new because thats just me... But I dont see a problem...

Pretty Sure This Guy Did HiS Own Work...

$500 = Fuel System + Cams... OR Just New Cams...

i had knick in my cam on my ls1 when i popped the engine, when i swapped the cam to a new engine, i cleaned the "damaged" spot up with some emerycloth only on the small damaged spot to ensure nothing was sticking up that would damage the lifter roller...havent had a single problem.

 

[Turbocharged400sbc]

yeah emery cloth will work but a file would be better as to only remove any metal that is "proud" or above the surface.

get the fuel system and buy a tube of rtv, can of brake cleaner, and a couple of old hard drive magnets to clean and secure near the drainbacks to catch any tiny metal particles from the roller and cam cleaning each other up/wearing together.

youll be good, the st1r in the TR had lobe damage and no issues, same with the VS in Al's old motor...roller cams are quite forgiving

 

[SRT41320]

Thanks Guys
