Excessive oil passing into air tanks and purging out air dyer, HELP!

@nasriza

 

New or not it does happen. Rings never seated and it's passing oil.

Why can you not get warranty??

We are trying to help but your not listening

 

this cat compressors are #### ive had them go bad so many times and its always the same thing i've put new ones also with same problems just change air drier frequently and not really much other than that i dont know if you can contact cat directly to see if they have a solution for this but as far as i know they are #### and it just that always pass oil thru

 

It looks like a bendix compressor to me.

Yes they can be bad from new. I always do a break in with a new compressor.

I crack a air tank and run the truck on high idle and let the compressor cycle for an hour to seat the rings

Having said that , I've still returned new compressors for warranty for passing oil.

 

Ok, if have oil coming out the blowby of the engine, you have something wrong with engine. Crankcase is being pressurized and oil cannot drain from the compressor housing. I would be doing blow by tests next.

 

Ok, your story is not making sense as you keep changing the facts of the symptoms.
You did say oil is coming out of the blow by still! I reread your post over and over and I keep reading oil is coming out of the blowby. Are you confusing the blowby and purge valve, because they are not the same and totally different things!!!

 

I'm guessing he's confusing the blow by tube with the air drier purge valve
