shooting oil out exhuast

i have a 2000 7.3 and i was having injector problems replacing them the orings weren't sealing or the injectors weren't firing than finaly i got everything taken care of and got it started today now theres another problem after a couple of seconds running it started shooting oil out of the exhuast. the only think it might be is a cracked head or a broken o ring on the injector. i was going to do a compression on the cyclinders to see if the head was cracked so i loosened all the glow plugs than when as i was pulling them out the first 3 were soaked in oil from the threads down and the last one was covered with about 1/2 oil. is there any reason why the glow plugs would be soaked in oil

I would say the o-rings got messed up when installing the injectors.

Normal when the injectors are messed with. You can never get all of the oil out of the cylinder when you clean it out before you install the new injector. The oil does not burn and it is shot out of the cylinder on the exhaust stroke with the exhaust. Makes a total mess. I put an old sweatshirt over my exhaust to catch the oily mist from getting all over everything.

If it does not stop within a couple of days, then check the O rings on the injectors.

i can understand that some oil would be shotting out the exhuast but from the puddle i saw just running it 15 sec i would be afraid to run it 10 miles and the pan being dry

I just had that problem about an hour ago. Turns out i didnt get one of my injectors seated well enough but it didnt cut or damage any o-rings. It drained about 1.5 quarts of oil out in about 5 minutes.

I just unplugged 2 injectors at a time untill i found the 2 that made the least amount of difference. (mine had a miss). then i pulled those 2 injectors and resealed them. One injector tip was hot from running and the other was a lot cooler. I just resealed them and hoped for the best. So i got lucky and it worked.

i went this morning to look at the injectors and it looks like the reason oil was shooting out the exhuast was that the #1 injector wasn't tightened down all the way so i torqued all the injectors down again and the cranked the truck over a couple of times and it finally started i let it run at about 1200 rpms for about 4-5 min and slowly i was able to get more rpms but i've run it for about 15 min and it revs out at 2500 and from idle to full throtle it takes a good 6-7 seconds to get there. i thought it would clear up the more i drove it but as soon as i put it in drive it maxed out at 1200 in first gear and not able to go over 10mph and theres not enough power to go up any kind of incline. it feels like i don't even have 10hp. when the engines running there a p1316 idm codes service engine soon light on but as soon as i turn the engine off the code goes away. before i replaced the injectors there weren't any codes now there is. what would i need to check?
