Thanks, I couldn't find it, so went to the Ford parts dept. The entire PCV assembly was $45, so not too bad. On the 98 that I have the part doesn't have an elbow. Odd that they don't just sell that rubber connector.

Cleaned the throttle body and checked all of my vacuum hoses while I was taking it apart.

 

Good deal, - you must have a 4.6L or 4.2L then. Yea, some of those just curve , then use a straight rubber connector.

Don't forget a Motorcraft PCV valve. ONLY RUN a Motorcraft valve with this PCV system. Third party valves lack the proper margins for this system. That little valve is very important to your engines health and longevity, - so use the correct part here, no substitute.

 

from oil sludge?? you know what PCV does right?? Postive Crankcase Ventalation. so how is VENTING it to the engine compartment going to give me sludge rather than it going into the intake???

Back in the 50's/60's/70's they had a pipe that just pointed at the ground for a PCV.

All a PCV does it relief engine pressure so it doesnt blow seals off....

i change my oil ever 3,000 miles since i got the truck at 97,000 miles. and after i put the PCV filter on the oil didnt look any differnt....

Ever looked at race cars and drag cars and old muscle cars??? those guys even put filter on there oil caps....

when my motor blows up from having a filter instead of a tube to the intake ill be sure ur the first to know.....

haha you guys are funny around here latey

 

Not quite.......

You have changed your motor over to "crank case ventilation". The "P" in PCV came from when they started hooking the vent tube to the intake to make it Positive b/c of the manifold vacuum. This was a "clean air" thing they did so the oil fumes/gasses would be burned instead of venting into the atmosphere.

I don't know if it will kill/prolong the motor life, but it will cause a big FAIL at alot of state inspections.

 

yes thank you jgger. i can see a very fine white smoke come out of these filters so i know they are venting.

MI has no state inspections. i have No cats/No EGR and no PCV i had an emission class in school hooked it up to a sniffer and it made the same emissions as a 97 Ford taraus with all of the emissions crab. i had 10 more Co2 Per min than the taraus

 

Even in the bad old days with the "road draft tube", it was shaped so that the air flowing past it would pull a vacuum on the crankcase. They did this to help water, gas, and combustion products evaporate out of the oil.


I wonder what the sniffer would have done near the crankcase filters. I'd bet HCs would have been off the chart. Not all emissions are out the tailpipe.

Look, bottom line is that I may have been a little harsh when I implied that you'd sludge you engine without a PCV. Engines run hotter, and oils are a lot better than in the '50s. Will it cause long-term damage to your engine? Maybe, maybe not. I assume that the Ford engineers know better than I do. I've also noted that every 4-cycle gasoline engine I've ever seen that's been built in the last 30 years (down to lawnmowers and pressure washers) has had some sort of factory-engineered way to put the crankcase under vacuum, so I assume it's important in some way.
