I have a rotor that has some small, slight indentations that seem to have been done by a broken apex seal. The indentations are not near the apex seal groove but a bit farther down on the rounded side of the rotor. I know ideally it should be smooth but will this really affect anything?

i would buy a new one myself.. but a pic would be helpful..

should be fine imo i've seen people use some pretty messed up rotors before and still get 120 compression on a rebuild and are still chuging along till this day

Here's a couple of shots of the rotor, 2 different faces.

I'd get a new one. No question about it.

ouch no way

that rotor doesn't look too happy... in fact it looks sorta

importboi22

i retract my previous statement

RXciting

Look like you abused that rotor with a small hammer

Bad YOU!!!

haha.. get new/used ones...they are a dime a dozen

Hehe..ok, I guess I'll have to try and find another one. Just for my own FYI, what exactly would happen if this rotor was reused? I know this sounds like a dumbass question but it's for my dad's benefit. He says I should be able to reuse it no problem. Thx.

well not an expert opinion but if those dents pussed the face off the rotor out a little wouldn't it scratch up your rotor housing?

That is why I was asking because the dents do not protrude in any way. There are no sharp edges sticking out that could scratch the rotor housing. I am just wondering if that area of the rotor face has any sealing characteristics. Obviously if it does then because of these grooves/holes then it would not seal that section properly. I don't know....

if theres no damage around where the apex seals sits and it is just the dents in the faces, they would be useable and over time it will be filled with carbon deposits. On the other side, water/air can get into the dents and rust it out (correct me if im wrong).

ZachSpazz

I talked to Rob Golden about chowed rotors, and as long as the dents are not near the apex seal grooves you can reuse a mild case with a little sanding of the ridges.

That rotor looks like it's been shat upon. S4 TII rotors can be bought for $50 or less.

tooks the words right out of my mouth.

its not the big dents that will hurt you, its the ones close to the apex seal.

other then that use em if you wanna be cheap and save a buck.

also make sure you lightly sand over them just to be safe that there are no sharp edges around the dents.

importboi22

wow i didnt think about that..... man im so dumb that rotor is reusble now that i think about it.....

RXciting

true but y not spend some $$ on your baby and her her some nice new rotors?

importboi22

*** new rotors .... i'd rather get new rotor housings and some nice used rotors for the same price

RXciting

lol true... meh i'd just get a whole new engine at that point

I'm not trying to rebuild this engine on the cheap and have it go again in a year. I am just trying to reuse whatever is reusable. If I had the money, I'd spring for all new everything.

cool - a big triangle paperweight

Judging from what others are saying, they are not reusable, due to the gouges up near the apex seals. I don't think that would last even a year really.

As you can see in the first pic, a scuff extends into the apex seal guide. This rotor is unusable. It could be possibly be used, if the guides were machined for 3mm apex seals, but I wouldnt try it. But as stated before, the other marks would need to be sanded down to ensure no protrusions in the face.
