Bending push rods
I have a problem with bending the push
rods.. Have you ever seen this problem.. Last year it happend 2 times. I
changed the oil and the engine was running on idle for 10 mins and then
bang!!!!!!
Changed 2 push rods and this time it ran for 10 hours and then bang.. changed
the push rods again and it went good all summer.
This year i started the engine up and it was idling for 15 minnutes.
Changed the oil and filter and it ran on idle for 5 min. and Bang again..
6 of the pistons had marks from the exhaust valve????????????????
All the timing gears are in the right position.- I cant realy understand

ya sure you wanna open that can of worms kwik???? we know this has been beat to death before.
The more I read and just think about it, I dont buy the wet stacking issue.
our diesel tractors idle for up to 45 mins at times and never had a problem, I-6 International engines, 412 and 436 CID. I have seen diesels in big fleets idle all nite when it was -20* this last January. mine idles for like 5 minutes tops, but I live in a state know for its COLD COLD winters and I have never heard of a problem around here.
so... It could be wet stacking, but I don't buy it. cam out of timing is a posibility, but the wet stacking makes sense.
so... sorry no assistance, just my .02

It is a strange engine.. 
6 of the pistons had markings from the exhaust valve in them. Wery wery litle mark. Cam is not of... Then the litle key that holds the GEAR to the Camshaft have to be broken.. Anyone know if the push rods have an up and down side to them?
In one end its a smal hole and the other end i a bigger hole.. Belive this is the oil is supose to go..
It also hapends after oil change...
This is a monday engine or what.

444dieselrod I'll be the first to concede that I don't know a lot about the innards of the PSD. I've just read a lot here and there in an attempt to learn. So let's toss the wet stacking theory for now.
So that leaves us with??? How about a stuck relief valve in the LPOP making too much oil pressure and overpumping the lifters?

i found this, it was the only thing that mentioned push rods:
Some 2000 PowerStroke engine may exhibit bent/out of position pushrods, damaged rocker arms, or damaged valve at low mileage. This may be caused by mis-manufactured rocker arms and/or pedestals. Inspect the suspect rocker pedestal for signs of scraping or breakage. If any rockers are date stamped "LB051" or "LB061", all 16 should be replaced, whether damaged or not, with parts date stamped "LA***". If any rockers are damaged and have an "LA" date stamp, International should be contacted. Have the numbers from the rocker available when calling. SSM #14285, Broadcast Message 1471

Castrol 15/40? Is it diesel rated? If so, fine. However, the only Castrol oils I've used were NOT diesel rated (used them in motorcycles and gassers before I switched to synthetics).
I'm not suggesting this is the cause of the rod problem - but I would be concerned about using a non-diesel rated oil as foaming in the oil (diesel anti-foaming additives are a must) can really mess up the injector operation.

i've had my 02 7.3 idle for a long time... never had any probs...knock on wood... and i do fill my filter when i change the oil.. i have always done this on any engine i could just to minimize the amount of time that the engine runs without oil pressure when you first start it after the oil change... and that filter holds 2 qrts of oil..! how many psd owners have ever had an engine problem after letting it idle for a long time..?

I fill the filter with oil on any engine that it is possible - the wife drives a Civic (helps make up for the fuel my PSD uses...). The filter on that thing sits sideways - no way to add oil before installationo. Of course, it isn't unique in that. Lots of cars are setup that way.
