18R(C) standard cam identification

[sleepin22]

HI,

is this an original standard 18R(C) cam? has the number 26 under the toyota stamp and the number 4 along the shaft. No other serial numbers are present. I just want to make sure so I dont send the wrong cam off to be re ground.







any help would be greatly appreciated

i dont think so - an 18R(C) doesn't have anything being gear-driven from the middle of the cam nor cam-driven at #2 cyl.

Are you sure that's not a 2S cam?

[sleepin22]

No I'm not sure what is in fact. The guy I got it off said it was for an old toyota 2ltr engine. I was hoping it was for the 18R(C) but as I have not yet seen an 18r cam before i dont know what it looks like. Pretty much got it for nothing so I grabbed it.

well if anyone can identify this cam it would be super. That said, are 18RC and 18R cams identical?

[sleepin22]

well its definately not an 18R(C) camshaft.

[thechuckster]

18RC and 18R cams are nearly identical (minor differences in lift and overlap)

[sleepin22]

so would it be ok if I got an 18RC cam reground and put it into an 18R?

[thechuckster]

why regrind it? differences would not be noticable - just gently clean up the bearing faces (no heat!!) and shove it in there.

[sleepin22]

regrind it to mild performance spec

[thechuckster]

in that case - grind away
