Archived Frozen Breather **Blown Pushrod Cover Gasket **

[csavard]

Hi everyone... .



The Yukon winter got me !!!



After a week of 40C below, I neglected to knock the ice out of my 99's breather tube. I was less than delighted to go out to the driveway & see a shower of oil spraying the ground under my baby !! I guess the back pressure in the block blew the push-rod cover seal.



I have unplugged the breather tube & am running the truck still ( after adding 2. 5 liters of oil ) but it is still leaking from the seal. Not a lot, but enough to make me nervous. (about 1/8 cup an hour of running)



I have the new seal on order & should have it on Monday. Chrysler wanted $60. 00 CDN for it and Cumins has one coming in at $25CDN.



Anyone know what the difference may be in the seals ?



Has anyone changed this seal before ? Where do I start ? Do I need other seals as well if I have to remove the Pump ?



Thanks





Chris

This can be especially bad for guys who have extended their breather tubes, and managed to leave a loop along its path that can trap and hold crud that then freezes...

The camshaft cover gasket lists at $32. 50 US at a D/C parts counter in the states.



I believe the difference in the gaskets purchased from D/C and gaskets purchased from Cummins will only be the price.

You need to remove the injection pump and the fuel filter. Cl;ean the area with lacquer thinner so the gasket will stay in place. Be sure the rubber seals under the bolts are good, or replace them too.
