Engine/Transmission (1998.5 - 2002) Cooling Nozzles/ISB

[troutlips]

Who has had problems with nozzles dropping into the pan?

I'll have to check my book, but If I remember correctly the nozzle is blocked from coming out by the upper main bearing shell. However I guess it could break off.

The nozzle squirts when the holes line up in the crank and the bearing.

This is critical... ... I need to know. Sounds like the nozzle cannot fall out past the crank without being distroyed. Send me a picture. I am meeting with the district rep. today. Thanks

I may have a photo of this area at home but I'm at work right now. I'll get you whatever I can.

I just picked up the nozzles from Cummins. The failed nozzle does not have a ridge. I will post pictures tomorrow.



Cummins district rep indicated there is no explanation for the nozzle dropping and that it probably came out prior to the pull over Parleys Canyon. It is the definate cause of the #6 piston failure. Warranty issues are with the dealer because on contractural agreements with DC.



He also agreed that it could happen at anytime to anyone. That is a 911 fellows. Reference the design changes to the new engines in TDR issue #40, page 38 where they are now using a "J-Jet" which is the same design as the larger engines.



Stayed tuned for pics.

That is where the nozzle is pressed or screwed into an oil passage in the block and squirts oil on the underside of the piston-right? I got somewhat confused during your other thread and this one because of remarks by 340mark and others about the nozzle being under the upper crank bearing. That was an older design?? The only nozzles I have ever dealt with are the plainly visible ones in the side of the block (like on most heavy duty diesels).

GWHaley: You got it. With the piston removed and looking down into the cylinder from the top, you will see a "saddle", this is where the saddle jets live.



They are pressed into place. When they installed new nozzles (jets) on my block they had to tap them in place with a hammer. They are a green plastic.



The new 03 HO engines have J-Jets which serve the same purpose. However you will see from the photo in TDR, they are bolted in place. Ummmmmm, boys there must be a problem. Of course it was just a design change for the higher torque and horsepower of the new engines.



There is no barb to keep these from falling out. If the retention ridge on the oil receiving end breaks off it is subject to being blown out of its home.



You may think I had an oil filter failure. The filter was an LF3984 Stratapore. The proper filter for better filtration.

Nozzles under the crank is another design and I believe it was used on the 12 valve engines. The 24 Valve design sits just above the crankshaft and just under each cylinder.

53 block 1998. 5 24 valve. nozzle inserted from bottom into counter bore in block

Yes, thats it. Mine is back together and will pick up tomorrow. Check with your local diesel repair shops and ask them how many 24V, Fords or Chevy's they have seen. Ask about #6 cylinder failure on ISB's..... very interesting.



Fords win the prize for number of repairs, Dodge is next. Without doubt the #6 cylinder is where the failures are occuring on the 12V and ISB's. That is because it is the farthest cylinder from the cooling.

 

[340Mark]

Thats good news troutlips. I thought the #6 cylinder bore was damaged? How did they fix it soo fast?

:--)Now about your handle, who hung that one on you?

They pulled the engine and honed the cylinders. User name: Die hard flyfisherman.
