DieselD Posted November 26, 2007 Share Posted November 26, 2007 SO I have had a huge issue with rail block off plus eating up o-rings on LCFs. I have have a few on the F-series too but it seems more common on the 4.5 at least here. We deal with alot of barricade trucks that sit and run all night long. Some will just need o-rings then some are just stubborn and will return shortly with the smae issue. Well on this last one I look closely at the rail and found a mismachined surface that the o-rings ride on. Its right where the o-ring fails. I have since ordered a rail to fix this. I beleive this is something we should start looking closer at. Im sure the F-seris have the same problem and if we keep getting repeat repairs from this take a look at the rail. I will try and get a picture but its down deep in the rail. just a fyi to look out for. Quote Link to comment Share on other sites More sharing options...

eastendpowerstroke Posted November 26, 2007 Share Posted November 26, 2007 Ditto, the F-series don't fail nearly as offten as the LCF, they just eat the rings up on the dummy plugs no matter how the truck is used. I have a good mix of LCF's porta potty trucks, dump beds, flat beds, and dry goods box trucks some idle a lot some don't but all eat the rings up.

Alex Bruene Posted November 27, 2007 Share Posted November 27, 2007 I've had several repeat offenders... seems like they have about a 30,000km life span... Quote Link to comment Share on other sites More sharing options...
eastendpowerstroke Posted November 28, 2007 Share Posted November 28, 2007 I've had several repeat offenders... seems like they have about a 30,000km life span...(30,000km = 18,xxx in English)I've seen them not make it to the next oil change and fail again 5,000-7,500 miles (thats about 8-12km in Canadian). /forums/images/%%GRAEMLIN_URL%%/rofl.gif Quote Link to comment Share on other sites More sharing options...
DieselD Posted November 29, 2007 Author Share Posted November 29, 2007 Ive got some good pictures of the problem in the rail Im talking about. I left my camera at the shop the past couple days so I have not uploaded them. Nothing short of replacing the rail would have fixed this truck.

DwayneGorniak Posted November 29, 2007 Share Posted November 29, 2007 I am seeing this problem on F-series very very regularly. Quote Link to comment Share on other sites More sharing options...
Alex Bruene Posted November 29, 2007 Share Posted November 29, 2007 Sure, it happens of F-Series and Econolines quite often... but not nearly as often as LCFs. Quote Link to comment Share on other sites More sharing options...
Driverj Posted December 31, 2007 Share Posted December 31, 2007 Have any of you flipped the oil rail over and looked at it with the o-ring/blocker still installed-you will see the blocker tube isn't center-it's always off to oneside. this may be an offset drilling problem.just replace the rail when you see this. our shop has been seeing this for about 2 years.
