So I am in the process of replacing the engine after I dropped a valve last year. The service manual states that you need to disassemble and clean out the large master tank and replace the inlet, outlet hoses, and oil cooler and lines but it does not state that you need to replace the baby dry sump tank that is connected to the master tank to provide extra capacity. Does anybody know why this tank would not have to be replaced? It seems to me that if the rest of the oil system is compromised that I would have to clean out this tank as well. Or replace it seeing as it is impossible to get into it to clean it completely.

Does anybody know if I need to replace the baby dry sump tank or is there a way to clean it? Or does it not matter at all?

Thanks!

If it were me, I would replace it. No use in leaving any stone unturned where there could possibly be some metal shavings that will make there way into the oil and create another problem down the road.

Replace it...better safe than sorry.

I disassembled both thanks and cleaned them. They were both disgustingly dirty inside. If you don't have good pressure and solvent to clean them with to make the insides look new, I'd get new ones. It took a lot more cleaning than I imagined it would.

How did you disassemble the baby tank? I don’t see any way to open it up in half like you can with the larger master tank

And what solvent would you recommend to clean the insides?

MickVette

It doesn't split in half. I kept washing it out with solvent until no discoloration in the solvent. Keep in mind, I didn't have a catastrophic failure, I was just cleaning them while the engine was ot.

I used brake cleaner so the pressure could get in all the seams. I recommend replacement if you have debris in the tanks.

Brake clean and air pressure is how I cleaned mine. Completely disassemble the main tank because there are a lot of places where debris can get trapped.

I forgot to add about using the air compressor. Thank you.

I’ve disassembled three of them now to clean and sell. The piggy back tank is simply shaped as a funnel inside. It cleans out easily. There is no place for debris to remain inside.

What did you use to clean it out? Brake clean and compressed air or something else?

KENS80V

Simple Green and hot water. Then blow it out with compressed air. It is completely empty inside. There are no chambers.
