I put a damn knick in my center plates oil seal track the other day when i kocked it over accidently while measureing and stuff, onto the corner of and end plate. I very carefully ground it down falt as it had a raised up edre frm hitting. its less then a mm deep and bout a CM long, it doesnt cross both oil seal lips at the same time and its not in a place where it stays crossing a lip for very long. Do you guys think it will be ok?

Take a pic.

If the surface is still smooth, there is no problem.

i'm doing a motor right now that had a front cover o ring failure, and in addition to everything else it put some scratches in the side housings. they are not deep at all, more like a change in surface finish. will it really affect anything? or should i just have em lapped when i go to use em

I dont know if my crappy digi cam will show it but ill try tomarrow. Thank you for the responces, Lynn you think it'll be fine? i keep worrying about every little thing on this motor. I flipped out the other day cus the machine shop i got my housings cleaned at used a pressure washer, and apparently decided not to dry them after. Rear plate had a dusting of rust. luckily it came off with oil and the surface is still smooth.

Some street port racers extend the port past the outer oil scraper track. At full tilt, the added smoking is not noticeable. At idle it is. A discontinuity won't hurt a thing.



So long as the surface is smooth, it will work fine. I run over the whole surface with oiled silicone carbide 400 grit glued to a DA pad (random orbital sander) just to break the shine on used plates. Stay off of the bridge if it is a bridge port.



A bit of a mess but doing it in the cleaning tank works well. Non flammable solvent for sure. The solvent keeps the silicone carbide cutting fast.



Even in racing the iron lasts for years.

I made a couple boo-boos last night porting. Good to know it doesn't matter.
