Trouble shooting a no start again...

[xkillerxnatedog]

Well i think i can determine my valve stem seals are bad was cranking it over some an ran for a few seconds maybe 5 to 6 i got oil comimg out of my exhaust... Or could i possibly be lucky an have a bad pvc valve?

what plugs did you use? I don't see a part # on the ones in the pic. not sure if the 4.6 and 5.4 plugs are interchangeable or not. IMHO, the oil on the plugs is from worn valve guide seals or the PCV system is shot as the oil on the COP is minimal. its a PITA but if you remove your intake manifold, it would be filled with oil and the IRCP would be coated in oil. the bent stirrup on #8 plug is definitely a concern unless it was smashed during install. move up to 5w-30 oil if you haven't already. good luck

The plugs are the same as are the heads. Also the pcv valve is built into the valve cover, if you need to change it youll have to swap valve covers. Pull the pcv vacuum hoses and check for excess oil, its pretty common on these motors.

Do a compression test and visually inspect the rockers for damage or excessive movement.

How can i diagnose for a bad pvc system?

An plugs i used was motorcraft platinum

So there is oil in the pcv vavle tube so im assuming i just found my answer im gonna have to order a new valve cover cause they dont sell them separate which is kinda dumb...

You're always going to have oil in the pcv tube.

 

[xkillerxnatedog]

Yea but it shouldn't be sucking oil from my valve into my intake from what ive been reading should be very little oil residue in my pcv valve an pcv valve tube that would explain oil getting mixed in with my gas getting on my plugs coming out my exhaust

 

[07gts197]

Its actually very common for these motors to suck a lot of oil through the pcv valve. My point for checking it was for excessive oil not just some.

Yea but all the symptoms that im having now point too either a bad pcv valve or bad valve seals which pcv valve can cause with to much pressure build up

These issues will make the engine misfire and run rough, but they won't cause a no start.
I think you need to post a list of parts that you've recently replaced, and their brand name, so we can keep track of what you've done so far before you start throwing more parts at the problem.
I'd also suggest you have cylinder compression and leakdown tests performed on the engine to make sure it's in good health before you go any further.

Its runs for like a few seconds an just dies out, because of the oil mixture with the gasoline.... But new sparks plugs, new coil packs, 2 new camshaft sensors, 1 new crankchaft sensor, an one new maf sensor an ,new fuel pump new fuel filter thats pretty much it so far that i can think of that ive replaced i can keep it running if i stay on the gas pedal but misses real bad because of the oil gas mixture in my combustion chamber

 

[xkillerxnatedog]

... Heres a link of what my car was doing right before i replaced the camshaft sensors... But cleared up after replaced them... Then week later all this happens

 

[RLF9409]

I still think you have a bad sensor.

It is not the valve seals.

That build up on your spark plugs is gas. It turns that soupy when it gets compressed and doesn't burn.

Do you park your car outside? Is it possible that someone is out to get you and has put something in your tank?

No i wouldn't think so i believe its the pvc vavle im just gonna end up swapping it out an see what happens

 

[xkillerxnatedog]

. This is from febuary of this year car ran great up until the last 2 months..

I think you're reaching a bit here. If it was stuck closed and building pressure two things would happen. One, you wouldn't have any oil in your tube running to the intake. And two, the flow would simply reverse itself and go out the passenger side. But if you want go buy a set of cam covers. Get the laser etched Ford Racing ones, they look cool. I got a set but I cut my pcv valve out of it. But it won't get your car to start. Do this. Cap off both the intake where the pcv is connected and cap off the intake tube where it draws air into the passenger side, then start your car. Bet ya it doesn't make a difference.

 

[xkillerxnatedog]

Im saying if its stuck open, it can suck more excessive oil into the intake, causing the problems im having now... I was low on oil when i changed my oil but i wasn't leaking it out anywhere that i could fined... Maybe a quart in a half low.. An what can i uses to cap of both ends to see what happens.. I honestly dont see my piston rings or valve stem seals to go bad this quick nor my head gaskets cause my oil looked fine when i changed it an im not low on antifreeze...

If it's open it won't cause any pressure build up. Two, if it's stuck open it will only draw when it is under vacuum which it does when it's working properly anyways. It doesn't prevent anything from flowing out just from flowing back in and keeping the direction of air travel the same, to keep it from reversing. It's just a check valve, like back flow prevention. But since you know what it is, go get some new cam covers. These preferably, they look sharp.






But if you want to test your hypothesis go get some vacuum caps for the vacuum ports. Just go get an assorted set from autozone or oreillys.

 

[RLF9409]

I think you should take your cam sensors back and get another set. I hope you got them from a store with a good warranty... I think they are bad.

You also need to make sure you are clearing the codes before trying to restart.
