I am looking for a Ford F150 2017 2.7L camshaft that has the cam lobe. The website mentions four different variants (LH-Intake, LH- Exhaust, RH-Intake and RH-Exhaust) but I am unable to find which to chose.

Hi,

I'm not sure what you are asking. LH and RH indicates the sides of the engine. Each side has two cams, one for the exhaust and one for the intake.

When you say high pressure fuel pump, the pump is mounted on the right side. If you are replacing a camshaft, I feel they should both be done at the same time. Also, it would be wise to inspect the opposite side to confirm there is no wear.

As far as replacing the cams, here are the directions. Note that it does mention the install of the high pressure drive assembly. The attached pics correlate with the directions.

After filling the engine with oil, the oil must flow from the main chamber of the oil pan, through a check valve into the smaller side chamber to correctly register the oil level on the oil level indicator. This may take up to 15 minutes.

Pic 17

Connect the battery ground cable.
Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables - 2.7L EcoBoost (238kW/324PS)).
Use the Powertrain Control Module (PCM) Misfire Monitor Profile Correction routine in the diagnostic scan tool.
__________________________

I'm not sure why the manual isn't being specific to which of the two drives it. I suspect they think the tech will see which it is once the valve cover is off.

Let me know if this helps.

Take care,
Joe

Hi,

I just spoke with the owner of the site regarding this. He sent a better picture to me and it appears to be the exhaust cam. Take a look at the picture and let me know if it helps.

Hi Joe, thanks a lot for the replies. Really appreciate your help on this. Actually, I am working on a project where I am running the high pressure fuel pump standalone in a lab environment. To run the pump I was trying to buy the camshaft with the cam lobe. I saw there were 4 versions. Based on your advise, I think it seems like its RH-Exhaust.

I had the image below, It looks like the shaft with the lobe is in RH side of the vehicle as well. But I was unsure if it was exhaust or intake.

Hi,

That does look like it's the one. Keep in mind, the last pic I sent was a cut away view. So, the cam really isn't exposed. The lobes on the actuator will require lubrications. Otherwise, it will fail.

Let me know if you have other questions or need help.
