Detroit diesel teardown

I've got the motor tore down now guys and its a sorry sight. The main bearings are gouged major and the crank has a tight spot when you spin it. I dug a handful of chunks of the 3 busted rings out of the airbox, which is full of oil. The injector sleeves are also full of oil, which I don't think is good. Am I correct that the modern block has 2 upper seals and no lower seals? This is the way my block is. Any help on any of these issues would be appreciated.

(I have some questions for you. The 53 series is a wet sleeve engine. I would guess the two grooves you are talking about are the grooves that seal the coolant. If I remember correctly you only use one groove. The other one (bottom one) is in case the top one goes bad. Make sure the top of the block and the bottom of the block line up. Also remember oversize O. D. Sleeves are available in case the block has to be bored to get sleeve alignment. I am curious about the oil in the tubes. The tube seals the coolant and oil should not be entering the tube. It might be smart to have the head maged and pressure tested,If the head is cracked in the tube seat area find someone who can put an Irontite plug in and remachine it. If it does have engine oil how did it get there? Make sure you also check your injector protrusion and your valve recession. Do you have an S or N series engine?

Yes I believe you are correct about the sleeves. I think the oil is entering the injector tubes from the top in around the injectors. Are the injectors supposed to seal on the top flange of the tube? They weren't in very tight (just popped out with heel bar), could this be a problem? I don't know for sure, but I think it is an S series. The fact that it is a modern engine makes me wonder if it is not the original motor, so it could be an N engine. Is there a way to tell the difference? Thanks for your help.

Injectors pop out fairly easy on a Detroit.They seal oil out on the tapered shoulder near the tip.You should be able to find out if it is Standard timed or Advanced (N) timed by a tag on valve cover or gov.housing,the difference is 1 tooth on the cam. Be careful installing the sleeves,they have to push in by finger pressure only,before the sleeve seals are fitted & make sure they are the correct highth.Lube the O-rings with dawn dishsoap,not oil,or they will expand.

Josh,I forgot to tell you,the oil in the airbox is unburned fuel;a result of no top ring,starting fluid is instant death to a Detroit.If oil is entering through the blower seals you will see it,the rotors will look washed,instead of having a light sooty look.Check the cyl.head,53's are very often cracked,tough on camshafts also.

The blower rotors are washed and have an oily film on them. It took tons of ether to start before we tore it down, so is that why the top rings are broken and the airbox is full of shit?
Do the injectors seal down close to their tip? The oil was in the tubes around them , but not down on the tips, so is this nothing to worry about?Thanks for your help.

The injectors seal at the bottom and this can be checked using blueing. They do not seal at the top like I think you think they do. When checking the sealing area at the bottom you must torque the injector down. Another dimension that is critical is the tip protruion below the deck of the head, If you need to have the head surfaced, new tubes need to be installed which may be a smart move anyway. Do you have a 2 or 4 valve head? Find me on the Hart/Parr Oliver web site send me an address and I will get some literature explaining all this comming your way.
