PCV - Oil Burn, Part#, and Grommet

So truck is a 2003 with 80K miles. PCV never replaced. V10 does burn about 1 qt of oil every 700-800 miles.

1. Can this be due to PCV?

2. Motorcraft PCV part # EV 238 can not be sourced anywhere....dealer says its backordered with no ETA. There is a Standard ignition one available at OReilly's (part # V341) that is supposed to be a direct replacement. Is this Standard one suitable?

3. Grommet....I've read that valve cover needs to be replaced as grommets are not available and not intended to be replaced. Is this correct?

Thanks!

Update....

Just found a dealer that had a PCV Motorcraft EV238 in stock! And it does include a grommet!!

So that leaves question #1.

Any tips on removing grommet without breaking it into pieces and having it fall into valve cover!

At that age and mileage I wouldn't think the valve cover grommet would be in such bad shape it will crumble as you remove it. If that's a concern use a shop vac to suck up any bits that might flake off as you manipulate the grommet on its way out.

FWIW once you have a verified Motorcraft part number it should be fairly easy finding something online; eBay, Amazon, a general Google search etc.

Do you regularly fill it to the "full" line/hole on the dipstick? Don't do that

When you change the oil, put in 6 quarts. Run it for a minute, shut it down, then check it 5 minutes later. Wherever it is on the dipstick, that's "full". Don't fill it up to the top.

I learned this with my V10. When I sold it, the new owner came back and complained that it was using a LOT of oil. I asked what he was doing, and he was OCD about making sure it was up to the full mark. I told him the above, and he never used another drop of oil.

Also check the hose going from the valve cover on the driverside to the air intake. That is part of the pcv system and if that hose is cracked or leaking it can also cause the pcv valve to stay open and cause oil consumption issues

This is the problem I had with one of my V10s, the fitting was not completely glued together. Also make sure the dip stick is completely seated on the O ring, any air that can be pulled into the engine will cause oil vapor to be pulled out the ventilation system. To make sure you don't have a mechanical issue get the motor warm and remove the oil fill cap and power brake the truck and see if vapor comes out the fill hole, it's called blow buy or compression getting past the rings.

I was able to to remove grommet without issue. Installed PCV. Will check on hose from driver's side valve cover to air intake. Which, BTW, is where? At air filter housing?


NOTE: The Motorcraft package indicated part # EV238 which is what is called for. Inside, the part had a number of EV 233. What's up here?

If you find that the mark after 6 qts of oil is 1/8" below full mark, that is considered full, got it. But wouldn't oil consumption drop below new mark as it consumes oil? Was it consuming oil because it was overfilled?

EV238 is the PCV and grommet---EV233 is just the PCV part only. That's assuming your package did include the grommet?

I can't remember if there's a O ring or other type of seal but you can feel it seat when you put the stick all the way in.

The dipstick on the 2Vs is a bit inaccurate. When you fill beyond 6qts to the FULL mark on the dipstick, you’re over filling the crank case. The oil will get agitated and will burn off until it’s at the right level to not get agitated any more.

If you notice it always goes down to one spot on the dipstick but never lower, this is what is happening. If it just continues to disappear, you’ve got other issues, obviously.
