[@CarlosDieselElectric]

Jonatan Solis by metals, I assume you are talking about main and rod bearings?

[@nathan00campbell]

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.

[@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.

[@redboyize]

Did you replace the manifold in the oil pan if so how did it do ??

[@raymondwandell8880]

The o rings, do you install them on the tubes or in the holes? Thanks.

[@CarlosDieselElectric]

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.

[@user-vu5pw4nu5d]

For a Cascadia 2019 what would be the pressure hot and cold. Thanks

[@CarlosDieselElectric]

The 2019 engines use 10W-30 which will give slightly lower PSI. Cold PSI should be at about 60 at idle Hot PSI should be at 15-19 at idle

[@CarlosDieselElectric]

At idle you have different PSI, at a higher RPM you have a different PSI. Which were you asking about?

[@tmg9280]

Is it really necessary to prime the oil system? Can you just start it up, let it run till the oil pressure comes up?

[@CarlosDieselElectric]

It is a precaution, priming the oil is to prevent engine seizure or failure in the event you have along crank situation engine failure can occur. Priming the oil system takes a few minutes and is well worth it.

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

[@MrDeepa32]

How do i know when its time to change oil pump, does it gives you any warning, can you please let me know

MrDeepa32 when the engine is cold and you start the engine. Oil pressure should always be at 60 psi or more at idle. Also, look to see if the needle fluctuates or does it hold steady.

[@MrDeepa32]

Carlos Diesel Electric thank you sir

[@CarlosDieselElectric]

Jayden Centifanti on the seals I only use assembly lube or clean motor oil to allow the seals to slide in. The seals will seal properly once they are installed and the engine starts to run.

[@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.
