D3logistics Posted May 26, 2016 Share Posted May 26, 2016 Greetings, was driving down the road and all of the sudden diesel was spraying out of the passenger side forward injector. Took off the heat shield to get to it and found the left bolt Head snapped off and rest of bolt finger loose. The other bolt was a couple of turns loose. Removed injector, cleaned area and had to replace the worn-out o-ring. All seems to be well now but not sure what may have caused it. Totally OK with wear and tear but worried it is a symptom of something else.

fjh Posted May 27, 2016 Share Posted May 27, 2016 NO Relation ! But do replace all of the rest of the bolts! this is simply an age issue from what I have seen! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/45380-99-rd-688s-injector-bolt-loosebroke/#findComment-334661 Share on other sites More sharing options...
Polarhound Posted August 16, 2016 Share Posted August 16, 2016 Things like this are why we always strongly recommend never reusing the bolts. Over the years have had a couple occasions where a customer wanted to save $5 by reusing EUP bolts only to have one come loose or shear. For a couple of years I kept a broken EUP one guy brought back; when the bolt broke, it rattled so hard that it broke into a dozen pieces. Whenever someone protested about getting the bolts, I'd slap that bag down on the counter. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/45380-99-rd-688s-injector-bolt-loosebroke/#findComment-342635 Share on other sites More sharing options...
