So I thought I’d post a recent maintenance issue that I came across that caused some costly repairs.
Cousin has a 2010 Ram 2500 with the 6.7. Bought it used last year at 160,000 miles and it’s been an all around solid truck. Called a couple weeks ago and asked if either of mine drip oil. Both are very low mileage 12&13 with zero leaks, so no.
He said a drip appeared, but nothing significant. Told him bring it over and I’d check it out.
He came over the following weekend after towing his trailer on a camping trip and parked in my driveway. I walked out 20 minutes later and there is a significant puddle on my driveway. Look under, have him start it and oil is coming out behind the balancer.
Pressure wash it, tear it down and remove the timing cover. The front main is blown out. The internal is literally inverted out in 2 separate spots. Immediately checked the Crankcase filter and it weighs way more than it should. Tear it open and it’s completely plugged.
I replaced the crank seal and resealed the timing cover. I have significantly slowed his leak, but found that the pressure also blew out a small section of the main timing gear housing gasket.
This requires cam removal and I told him to take it to a shop. If it was my truck, I’d have no problem tearing into it, but not worth the headache for me.
My guess is that he blew the timing housing seal originally with normal driving and low boost. When he went camping, there’s a bunch of hills so plenty of boost and crankcase pressure significantly increased and spit the crank seal.
I installed catch cans and gutted the ccf on both of my 6.7’s for under $40, or new crankcase filters are $50-60. Either way you go, it’s cheap insurance to prevent some costly damage.
