Is it better to place the PCV near the top or towards the bottom of the heads. Has anyone noticed less condensation in either position? TIA MM | ||

Top is better if you can fit both there. The S2 guys usually use two front covers to clear the gas tank. You will get less oil in the crankcase air if you fit both of them at the top. | ||

That's the way I did it. I also had a look at S1owner's SXB build 2 and seen where he put his covers. Thanks MM | ||

Is there a cheaper source for those pcv valves, they seem to run $30-$35 ea. That just seems outrageous to me. | ||
| Ratbuell |
Then use the old rockerbox style... It's not like the PCV valves will ever go bad. Buy 'em once, done. | ||
| Phelan |
They are $30-$35/ea new but hit up Paul Podlasky (PudPaul) or Jeff Robey (Jrobey) as both usually have PCV valves for $10-$15/pr from used bikes. | ||

I have clearance issues on my 2000 S3T on the rear PCV valve. I had to run the output sideways to the left and add a couple thin rubber bumpers to keep the tank from resting on it. | ||

Might want to check that area for wear. The vibration of the engine, even with a rubber bumper in between, could be wearing a hold in the tank. | ||

Hopefully he put the bumpers on the frame rails, not above the PCV valve. I had the same issue, which is why I swapped the covers front-to-rear. Rear still touches, but the tank mashed the valve down so there is no danger of perforating the tank. Been like that a couple of years, no mark on the tank. | ||

I also had to rotate the rear to the left. Noticed a slight rub on the covers paint because of the offset on the PCV but really no mark on the tank. MM | ||

...yes I did put the bumpers on the frame and no there isn't wear anymore (not my first ghetto mod and won't be my last...). | ||

I still have original thunderstorm heads & rocker box, i put two small S&S one way valves on my breather hoses, probably a waist of time but a friend with a tuber carb model put some on & saw his trap speed at drags go up from 112mph to 118mph standing quarter | ||

On my 2001 S3T, I shortened the rear PCV by removing 1/4" from the center of the body. This gave me clearance to the bottom of the tank. (I carefully sawed out a section with a hack saw and bonded the valve back together with ABS cement.) When you open up the valve, you find that the large chamber is full of a plastic mesh material with an umbrella valve at the bottom inlet. It is the same umbrella valve used in the old rocker box. This was not an original idea, I saw it on this forum back in 2010. Barry Hollister, CA | ||

good info Yo Barry , thanks, i know the umbrella valves can stop doing there job, thats reason i put the small S&S one way valves one on each hose. the top rocker PCV valves nothing new, we used to make our own & drill hole in top of rocker box with old Harley shovel heads sometimes two in each rocker for racing, shovels breathed from the cases not each head so made a good gain. but too much crank case breathing and the oil drops out the bore so more for drags than a road bike. | ||

I'm still puking oil into my air cleaner even with the XB conversion. Has anyone tried 883 cylinders and pistons? I don't need to run over 100 mph ever. My Sportster never had this issue and had 130,000 miles on it when I sold it. Lakes, do you have a part number for the in-line S&S valve? (Message edited by harleyelf on June 11, 2015) | ||

Harleyelf, you may have excessive blow by from bad ring seal. 883 cylinders and pistons won't solve the problem Amy better than simply honing out your stock cylinders and using oversize pistons and new rings, though it's not much more to upgrade to a 1250 kit, which ours have thicker iron lining that doesn't expand as much as stock, so they hold their ring seal quite a bit better. Just follow proper break-in procedure. And I happen to know the guy that preps all the cylinders and ring gapping in the 1250 kits, and he's pretty good at it, and is probably the coolest guy that ever was  . | ||

"They are $30-$35/ea new but hit up Paul Podlasky (PudPaul) or Jeff Robey (Jrobey) as both usually have PCV valves for $10-$15/pr from used bikes." I can't find any PudPaul in the members list here, is that the correct name? Got hold of him on ebay, but their no email address policy is sort of screwing up communication. | ||

Sorry John I think may actually be PaulPud. | ||
