Stumbling after injector o-ring replacement
I have a 2000 7.3 and it suddenly wouldn't start. The oil was suddenly 2 quarts low and I never have to add any between changes but check it all the time. The tach was jumping so I figured it wasn't the CPS and with the low oil decided to replace the injector o-rings since I knew I had 2 bad glow plugs and was going to go ahead and do them all so might as well do the o-rings while in there. Once I finished that, it still wouldn't start and nothing from the tach. Put in a CPS, and after some cranking, it started. It's now taking longer to start where it used to be pretty immediate. A puff of white smoke when it starts. It idles fine. Took it for a test drive and it was stumbling, stuttering or whatever pretty badly. Like's it's running normally for a few seconds then hesitates, then back to normal. After a 1/4 mile of this it starts pouring white smoke out. I stop and the smoke stops and I limp back home even slower.
I've read where the truck may not run normal until all the air is out of the system but I can't drive it anywhere like this. I also read that white smoke can mean a loose injector. They all went back in smooth enough. I can pull them and check the o-rings and re-install them. I don't have a code reader. Are there any other tests to determine if that is the issue and which one it is? Thanks.
