hi does anyone have a air intake curve and cap for a mack midliner ms series. thanks

Checked mack dealer. Need to go in and see it its the whole peice or the top. None on ebay. Didt see it on here. Cant find a salvage yard.

hello everyone. i have a 1999 mack midliner ms 200p that is missing the air intake pipe that goes behind and on top of the cab. its that curve shape that is found on most midliners. does anyone know where i can buy this. thanks

Ok.....I made a Boo Boo. The starting aides were no longer installed with introduction of the Midliner RVI "ACE" engines.

The ACE series engines we had at the fleet I worked at had no starting aides. RVI engines in Midliners never had in cylinder or precombustion chamber glow plugs. The 1992 and up to 1996 Midliners used that glow plug in the intake setup.

Get the codes checked first, go from there.

its ok we all make mistakes. thanks alot for the help tho.

You may want to have Your midliner scaned for codes. If your check engine light is on, it was very common to have your timing event sensor fail. The sensor is located on the injection pump drive gear in the top of the timing cover infront of the driverside mounted injection pump if I remember correctly. Check out your codes first and work backwards from there. I believe that engine worked on V-Mac I or II supported pro-link readers. That series of motor is ACE which has a computer for certain sensors.

ya ill get it checked for codes. the only problem is that the truck is sitting down and is not registered to the state. i have to try to get a mechanic out to check it. also dose anyone know the heating source of diesel in this truck. glowplug or intake heater or none. thanks

Follow the intake manifold on the driver side of the motor all the way to the front of the manifold (where the Manifold meets the hose that comes from the charge air cooler) The starting aid will have a clear plastic fuel line attached to what looks like an injector. right beside it will be a glow plug looking unit with an electrical connection on an eyelet connector. if your issue is only start up related as I do recall that series smoking bad on start up due to this starting aid. Its a fuel injector that injects fuel into the intake at the front of the manifold and its heated in the manifold by the glow plug (stuuuupid system) With that many miles you could have more wrong.

Good luck.

i am having trouble finding this. is it on top the middle of the engine i see there are a couple of connectors with a hose right there. is that it ? also can this cause the truck not to start up without starter fluid or battery jump?

also there is a smoke with a blue-ish tint to it

thanks for the reply. i will check that next time i flip the cab. what does the starting aid look like?

It smells like fuel.

Nope. None at all. No water in oil either. Doesnt burn oil or water.

Hello. I have a 1999 Mack Mid-Liner MS200P with 450,000 miles on it and it smokes like hell. It overheated once and thats when it started to smoke. The engine service like IS ON. Can if be glowplugs. I have to leave ignition on for a couple of mins or itll kill the batter cranking or need starter fluid. Thanks. Please help
