Question about 1997 Ford Escort

2 Answers

Positive crankcase ventilation system

I need to identify the part that installs on the engine,the pcv valve goes into it(in a grommet) then the hose goes on over to the intake.Is it the evap canister?Or the canister purge valve?Or something else?It looks like it has a massive oil leak,plus ,it may be contributing to the idling problem.Thanks,Dave Braun.

    I'm sorry guys.This was not helpful at all.I've got an oil leak just above the oil pan,right behind the exhaust manifold.It's also got something to
    do with the pcv valve not wanting to stay put in the grommet.I had to wire it in place.And there is a lot of oil leaking out from around the pcv valve.Do you see where the pcv valve sits in the grommet?Then goes down to the engine block,somewhere just above the oil pan. Remember,this is a 2.0 4 cyl. engine...Thanks,Dave.

    Yes,thanks Ray.I haven't actually got on it yet but when I do I will be better informed.I really should do it this weekend and get it done.I realy did not want to do it before the 1st so I could still use the car in the meantime.But it kinda sounds like there is a backup of crankcase gases and that is blowing the pcv valve out.Also the oil leak could be the vent tube just needs a o-ring or gasket.I'll chack the pcv valve 1st.Sorry,Ray & its420_us .

  • dbcolorado May 29, 2009

    Hi Ray.No,I haven't fixed it yet.Even drove the car today.Need it to drive because the truck does not have any gas in it ! But just after the 1st.Meanwhile,The a/c is on the fritz too.I am trying to make it work by using a stick to push against the clutch on the compressor to make it engage...dumb,but most of the times it works.Is the clutch the problem here,and can I replace it myself at home?The a/c seems
    to work fine,when it engages.Thanks again,for your very fine help.Dave.

  • dbcolorado Jun 27, 2009

    Hi Ray.No, I haven't fixed it yet.Keep having money problems.Maybe this week.Try to fix the oil leak and see if fixing that oil separator tube
    problem while fix the idle problem,will also fix the a/c.It keeps cutting out.I know when I do all that,It will seem to be a major irritation, but coming from a minor part.Always...dave.

    7/4/09 Saturday. Well,I got started on the Escort.I got the oil separator off.Haven't washed it yet though so I don't know if it is cracked,broken or I just have oil leaking out of the top of the pipe because of the grommet being bad.It is burnt,and oil soaked.There is a lot of oil all over the lower front side of the engine. I wonder if the ONLY problem is the grommet being shot,or is there still a chance that there is a vacuum problem at the intake?The (newish) pcv valve,less than a year old,is not stuck.BY THE WAY-the ford part number for the oil separator is - F7CE-6A785-AD.I can't find it anywhere so far.That also leads me to believe that it is not meant to be replaced,ever.I just need to figure out the source of the leak,and replace the grommet & pcv valve.Hey ! I put the new fan switch in the truck !

The part that you describe is the valve cover, yes they do leak oil, especially if the pcv system is not working properly

    sorry about that,i was having a senior moment,now to the problem. first check that you have vacuum at the pcv valve,if not keep going backwards untill you get where the pcv hose goes to the intake manifold,if you still have no vacuum,take the hose off at the manifold if you don't have vacuum take a drill and clean out the fitting at the manifold, once you have vacuum all the way to the pcv valve the problem should be gone. if you need more help get back to me and we'll go from there. please re-consider your negative rating we're all human.get back to me and we'll go from there Thanks Ray

Your pcv valve connects to the "crankcase vent tube".

Posted on May 15, 2009

  • its420_us May 15, 2009

    The tube for your pcv valve goes from you intake plenum, directly above your egr, then over you valve cover, and you pcv valve fits in the "crankcase vent tube". If you nedd help resolving your issues, I'm in Denver. Email me at

  • its420_us May 20, 2009

    I don't understand what wasn't helpful, you asked to "identify the part" that your pcv valve sits in, and I did just that.

    The blowby vapors that end up in an engine's crankcase contain moisture as well as combustion byproducts and unburned fuel vapors. The crankcase is sealed to prevent the escape of these gases into the atmosphere, but the vapors must be removed to prevent oil contamination that leads to sludge formation. The positive crankcase ventilation (PCV) system siphons these vapors from the crankcase and routes them into the intake manifold so they can be reburned in the engine.

    The main component in the PCV system is the PCV valve, which is usually located in the valve cover. A hose connects the PCV valve to the intake manifold. A second hose between the air cleaner and crankcase or other valve cover (V6 or V8 applications) provides fresh air to help flush the vapors out of the crankcase. Some engines have a separate air filter for the PCV breather hose located inside the air cleaner.
    Probably not read above for details.

    Location fo pcv valve on 2001 ford ranger 4 cyclinder 2.3

    I think it is in the valve cover. see illustrations from shop manual.

    Positive Crankcase Ventilation System Overview The Positive Crankcase Ventilation (PCV) System (Figure 132)cycles crankcase gases back through the engine where they are burned. The PCV valve regulates the amount of ventilating air and blow-by gas to the intake manifold and prevents backfire from traveling into the crankcase. The PCV valve should be mounted in a vertical position. On some applications, the PCV system is connected to the evaporative emission system (refer to the VECI decal). located on the underside of the hood or on the radiator cooling fan shroud.

    the pcv valve is behind the alternator between the alternator and oil filter. when you remove the oil filter you can see the pcv in the intake manifold. best way to get to it is through the pass side fender under the rubber mud flap thats between the wheel and engine.
