bward84 Posted September 16, 2011 Share Posted September 16, 2011 Have 10 F-450 6.4 55k miles and looks like its either leaking oil from the glow plug harness seal or the two piece head on the drivers side. So easy to tell when you an egr cooler in the way. Has anyone seen or dealt with this issue??? Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted September 17, 2011 Share Posted September 17, 2011 Welcome to DTS! I'm sure you'll find a lot of great help here without the censorship of FMC. Isn't the dipstick tube near there? I think some of the guys were having a cracked bracket on the tube mislead them on oil leaks making them think it was the glowplug harness. Double check it. For crankcase leaks, I take the shopvac outlet and use it to pressurize the crankcase (to about 1 psi) while the engine is running. This makes seepage leaks show up quickly in the bay. Good Luck!

Keith Browning Posted September 17, 2011 Share Posted September 17, 2011 Have you installed UV dye, run the engine and inspected with a black light? Quote Link to comment Share on other sites More sharing options...

Yep I have had the dipstick crack at the mounting bracket causing and oil leak. That was fun tracking down! put some oil dye in it and run it.

Is the oil leak at a particular portion of the engine such as number 2,4,6 or 8 cylinder location? Asking due to the idea that it maybe coming from a glow plug grommet.

Matt Saunoras Posted September 17, 2011 Share Posted September 17, 2011 the first dipstick took a while to figure out, they're cracking right at the bracket or sometimes rubbing on the horizontal cooler. Quote Link to comment Share on other sites More sharing options...

bward84 Posted September 26, 2011 Author Share Posted September 26, 2011 The dipstick tube was cracked just past the bracket. fun stuff. I added 3.5oz of dye and still couldnt see any in the oil. Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted September 26, 2011 Share Posted September 26, 2011 Did you seperate the steering shaft to get it out? Quote Link to comment Share on other sites More sharing options...

Dye does not work well in dirty diesel oil. Sometimes an oil change is absolutely necessary. Quote Link to comment Share on other sites More sharing options...
