I6 258 owners: how many Pcv valves do you use?
I know this has been brought before, at least the pro's and con's about the number of PCV valves to run on a 258 I6. But I'm curious how many of you are useing two?? . For example, I'm only using one which is in the forward grommet hole (closest to the radiator) and I'm running a breather cap (normally used on a older Ford 6 cyclinder.) in the back. The reason why I'm asking is, I have seen a few I6's that have two PCV's hooked up. In talking about this about it with some friends, a couple of them mentioned that 2 was a normal setup. Anyone know if thats correct? I dont think it is, but I dont for sure.
1. If you are currently using two PCV' valves, How are they setup?
When I dropped the 258 I6 in I'm using now, before I changed the setup, the motor came with two PCV valves, The forward PCV had a vacuum line that went to the bottom of the air cleaner. The rear PCV linked in at the manifold, next to the EGR valve. I drove it like that for awhile but started finding a lot of "blowby" into the air cleaner, not to mention some slight dieseling.
Now that I shifted to one PCV valve and the breather cap, my motor likes the arrangement a lot better....but it hasnt eliminated the "blowby" persay.
2. If you are only using one PCV valve,,,what did you do to eliminate the 2nd valve, and how are you running your vacuum lines?
I'm curious about this, because I dont really like the idea of a breather cap,,,and I'd like to find a better setup. However, until I do...I'll keep the cap.
It certainly helps my six's performance.
Any info you fellows could share would be appreciated....thanks
