I'm pretty sure it's the plastic section manifolds that have the problem. The o-rings are a problem on either style I'm sure. I'm actually trying to research and find out if the plastic and cast aluminum suction manifolds are in fact interchangeable. Freightliner will tell you they're not even if they are so that's not a good source. It seems like it would be a direct swap. The metal one isn't going to crack from oil pressure and blow out like the plastic ones do. Those fail on the pressure side, the o-rings tend to fail on the vacuum side

[@CarlosDieselElectric]

I agree with you. The older DD engines that first came out didn’t have the failure rate these plastic ones do. They are garbage IMO, I was told they will not line up underneath when they are installed. Something about the bolts on the suction module to the block. I have personally never checked.

[@redboyize]

I have a 2017 freightliner cascadia about 560000 miles and my oil gauge fluctuates up and down never steady, at a complete stop it goes low when I press the gas pedal to go it goes up and back down at complete stop again. Any suggestions could this be the pickup tubes or oil pressure sensor?

[@CarlosDieselElectric]

I would definitely start with the oil suction module and the seals on the tubes. ASAP I have seen this many times and it is most critical you have it looked at right away.

[@laranzowhite2481]

Hello. I have a 2015 cascadia DD15. I had my pick up tubes oil pump gaskets replaced. But I just found out that my mechanic didn’t change out the oil suction manifold. With that being said now I don’t have NO oil pressure so I’m getting someone to replace everything again including the oil suction manifold this time. Would I need to get a new oil pump again? It was replaced 2 months ago?

[@CarlosDieselElectric]

Oil pumps very seldom fail on the DD15 and DD13. Also try replacing the oil pressure sensor. Once everything is replaced, SUPER important to prime the oil system with at least 2-3 gallons in addition to the 10-11 gallons you are going to add. before trying to start the engine. I also like to soak the oil filter with clean motor oil.

[@CarlosDieselElectric]

Any knocking sound is always a concern especially with low oil pressure. Have you been able to drive or run the engine since this happened? I would personally look into the lower end of the engine. Look at the tubes, can you spin them? How many miles are on the truck?

I always install them on the tubes, apply some assembly lube (lubriplate No. 105). Once you install the rings on the tubes, use the assembly lube to help it slide into place. The lube will go dissipate once the oil warms up.

[@tryduck6993]

So you recommend replacing the pickup tube because you had to remove it already? You didn't want to replace the front pump where the front of the tubes went into that were spinning? Trying to understand your thought of why replacing the pickup vs just cleaning it and replacing the seals. Not like it had metal through it , top is aluminum where the tubes and rings are , but so is the front oil pump where the front of the tubes went into that you didn't bother replacing.Trying to understand WHY you replaced that but didnt bother replacing the front pump where the tubes went into.......

[@CarlosDieselElectric]

The oil pump is very reliable, the failure typically occurs at the pickup tube (suction module) and the orings will harden and allow oil escape. The suction module has an internal valve that fails and will get stuck. In my opinion, I automatically replace the suction module and the orings because I don’t want to run the risk of it failing on my watch. Now if this is something you are doing on your own truck then it’s your decision to make. But I don’t want the responsibility of engine failure because I didn’t want to change a part that cost less than $200.

Warranty coverage has changed. The engine warranty or power train is separate from injector coverage. After treatment coverage is another and transmission is another.
