5 oil fill riser to valve cover 0-ring
Posted by Sam Binkley on Apr 23rd 2025
The o-ring fit perfectly and stopped the leak. During the repair I discovered there was NO o-ring there! Someone had used silicone in place of the proper o-ring. 2003 F250 SuperDuty 6.0 PowerStroke. The order process was painless and I would recommend Riffraff Diesel.

5 Oil fill riser to valve cover o-ring

Had the problem of my riser unscrewing from the valve cover when trying to fill oil. This o-ring fits correctly. Pro-tip- use some rtv on the riser threads when you reinstall and you can keep this in place without oil seepage.
