Thankfully, for once.... this is not my car. But the problem is driving me nuts because I feel like I should have a list of reasons why, but I am just stumped? Must have missed that day of class... or I was drunk??

2002 Ford Taurus...

Car has no power at all. Stalls at WOT. And at moves at a top speed of 20 MPH at 50% throttle. Makes the worst noises, and smells.

I did a vacuum check for the guy, and its got 22lbs of Vac. He replaced both Cats already... and the fuel filter.

Today we pulled off the intake tube leading to the throttle body only to find about 1/2 a quart of oil dripping out! WTF?

I know I learned about this but I just cant seem to remember.

Bad PCV valve.

Check out this post on a ford site I found from yahoo:

That should solve your problems!

Read through it but I am still on the fence.

I thought about the PCV, and infact I pulled all the hoses and flushed them. I did not however pull the PCV because it is a PITA to get to and its not my car (thank god). But it is def. worth mentioning.

The only thing with the PCV that I am wondering. Would it really cause enough pressure to bog the engine to a stall on acceleration?

Another thing that I have been tossing over in my mind... I can't remember, but I think a clogged PCV would cause low manifold vacuum... not normal vacuum right? (maybe I am wrong)

DG

What is the vacuum pressure supposed to be?

Too much could draw oil in. Just a thought.

Matthew

PCV does draw oil residue into the intake, but there's also a pcv vent, and this overflows into the intake if there's too much blowby.

But neither should be filling the intake with oil quickly. Maybe the taurus has some garbage baffle in there or something.

Is there oil in either the pcv line or pcv vent line? A new pcv is about $3 so just replace it anyways.

We were playing with the car again today. I mentioned replacing the PCV and its a good thing we did. The other one was stuck and caked in sludge! So far everything we have replaced on speculation has been bad . The cat for example was missing substrate and was making a racket. But still the problem has not been fixed. The car still can't make it over 20MPH, and its sounds like a suffering cat (animal).

I think my next suggestion is going to be plugs. I don't see how plugs could force the car to barely run within just 100 miles of driving, but it seems like little or no maintenance has been done to the vehicle... so what the heck. (its not my money anywayz ) LOL j/k

DG

You didn't say what you did with the damaged cat, removed, replaced? Where did the broken substrate go? How about downstream and still plugging the exhaust?

plugged exhaust, cam timing, ignition timing advance, or a shot engine.

Those are what would cause the issue it is having.

That's the best diagnosis yet!

I think shot engine is where we are going to stand.... .


Ill find out more tomorrow!
DG

Have you done a compression or leakdown test? My LTD has two dead cylinders and doesn't blow oil into the intake.

Could be bent rods though on mine.
