joecool911 Posted November 12, 2014 Share Posted November 12, 2014 (edited) I'm assuming I'll need valve seals. Any way to do it without removing head or injectors? If I could figure out where tdc is for each cylinder valves should not fall in. Lol. #6 hard to do? Edited November 12, 2014 by joecool911 Link to comment Share on other sites More sharing options...
98whitelightnin Posted November 12, 2014 Share Posted November 12, 2014 My 98 would puff white on cold starts too until I switched to a p-pump, could be something other than valve seals. Link to comment Share on other sites More sharing options...

98whitelightnin Posted November 12, 2014 Share Posted November 12, 2014 Idk, my truck had 260k and the little puff bothered the heck out of me. I pulled the new injectors out and sent them back to contagious to have them checked, they sent me a whole new set and it still had the puff.

Administrator Mopar1973Man Posted November 12, 2014 Administrator Share Posted November 12, 2014 When to be a bit concerned is when the little puff of smoke smells like engine oil. Then you have oil leak. If the puff smells like fuel then you most likely have a injector issue. 1 Link to comment Share on other sites More sharing options...
joecool911 Posted November 12, 2014 Author Share Posted November 12, 2014 Always smells like diesel smoke. Link to comment Share on other sites More sharing options...
mulcher812 Posted November 12, 2014 Share Posted November 12, 2014 Could be a bad spring in an injector. Link to comment Share on other sites More sharing options...
rancherman Posted November 13, 2014 Share Posted November 13, 2014 is it every start up, or cold only? typically a valve seal needs time to leak down, so an immediate restart should be clean.... But on the other hand, a hot piston will mask a pissy injector too. ....... pretty hard to race around and smell that elusive puff... Pretty windy around here lately! Should have a blue haze if it's oil, but the sun shining from different angles can change the color big time. Lots of definitive answers in my post!

joecool911 Posted November 13, 2014 Author Share Posted November 13, 2014 I was thinking about running a hose to the cab so I can diagnose exhaust smell ;) 1 Link to comment Share on other sites More sharing options...

Dieselfuture Posted November 30, 2014 Share Posted November 30, 2014 I thought white smoke was ether air in fuel, or some sort of moisture. Link to comment Share on other sites More sharing options...
