Add a PCV catch can, or a oil seperator with an external PCV filter.
You will burn less oil, because the PCV system will be out of the loop.

Oh yea, forgot to mention, was using an aftermarket PCV valve but changed that out to a 100% genuine Ford PCV.

I wouldn't have a problem isolating the EGR + PCV system out of the loop!

Have the EGR ports in the lower intake manifold been cleaned?
I would expect them to have more of an impact on cylinders 3 and 4, but who knows?

Whatever you do with the PCV....you do not want to reduce the flow out of the crankcase through the PCV valve.
That would cause chemicals to build up in the crankcase, breaking down the oil, creating sludge, etc.

Now, if for some reason there is a issue with a intermittent lack of spark to cylinder #5, that could cause deposits on the spark plug.
If not the coil, which you have already replaced, which seems to be mentioned as failing on windstars around your year, maybe a spark plug wire.
So, if not already done......new plug wires and ......along with new spark plugs might be in order.

1 quart in 3000 miles is not much consumption, not near enough to be concerned about, or to make any changes based upon consumption.
I am doing that now on my '96, actually maybe a bit more, which has over 220,000 miles, .....but I am using 5W-20 oil.
I would not go to a thicker oil than 5W-30.

As far as any pinging......give the IMRC a looking at.
Around your year is known to loose clips that attach the IMRC shafts that go into the lower intake manifold......to the electrical actuator.....
What this can cause is for the actual IMRC to be open when it should not be, or to have 1 side open and the other bank of cylinders closed....which would cause a imballance situation.
It is worse to have them stuck open than to have them stuck closed.
Open is bad for low RPM operation.....as in lower than 2000 rpm......and lower fuel economy.....pinging and maybe lean codes.
If they are stuck closed.....you loose that extra power boost when passing......high RPM accelleration, but it should not cause any other drivability problems.

I cleaned the EGR ports when I did the isolator bolt fix a few years ago. They were very clean compared to some of the pictures I've seen of others around here. Maybe a pea sized piece of junk in #1 and #4. I also replaced those broken IMRC clips. I also already did coil pack and wires a few months ago.

I think I'm just gonna grab some new plugs and see what happens. It's the damn oil consumption that bothers me. I'll keep this topic alive with any new developments in case someone else is having the same trouble.

Get Motorcraft or Autolite "Double Platinum' plugs.
Stay away from multi-pronged fancy plugs.

If, by some chance, the wrong plug was installed, then it could be a cause of deposits.

I stick with Motorcraft for plugs...

Well, new coil pack, new wires, new plug, Damn P0305 came back this morning. Any thoughts??? I'm thinking Fuel Injector maybe??? That sound right to anyone else? The only thing I don't like is all those damn deposits on that plug and my oil consumption.

I don't think so. Oil can cause misfire. Cause the oil reduces electrical conductivity, even if you have new iridium plug. Maybe bad rings? Have you tested the compression?

DrivenByDemons · 01-22-2010, 12:40 PM

No compression test yet, it's on my list. Can I just check that one cylinder for compression without removing all the spark plugs? I was thinking I could pull the fuse to the fuel pump and just check #5 for now by cranking the engine.

wiswind · 01-22-2010, 04:22 PM

If you are thinking fuel injector, try swaping it with one from another cylinder....and see if the problem moves.

Yes you can. It will be quicker and efficient.

DrivenByDemons · 01-22-2010, 08:08 PM

I'll probably try compression test tomorrow. I pulled the #5 plug and it already has oil on it. A compression test won't tell me squat about valve guide seals, right? If I have good compression but still a lot of oil in that one cylinder only, it almost has to be the guide seal, right?

If it comes to that, that's my plan.

Yes, a compression test will tell you about a bad valve guide seal.
So the test is useless, I didn't thought about that before.

I think the engine need to be examinated by inside.
