He went old school before EPA and smog control. Old engines had a breather tube that rand down just below the engine and transmission to vent blow by. The big cap has a steel wool to trap any oil trying to get out. The oil from PCV valve goes into the engine to be burned. It makes engines run worse not better. In the 1960s and 1970s many people did this mod. New non-turbo engines don't have the blow by the old engines did.
The grommet fits perfectly, the pcv valve expands the grommet slightly to remove any loseness. The valve cover gaskets love to leak on the Cologne V6, lots of people have difficulty sealing them up. If you remove the valve covers for new gaskets, you might find the oil drainback holes for return to the crankcase are partially plugged with gack (cooked engine oil). Might be a good idea to clean that all up, this can result in excess oil consumption from oil backing up around the valve stems and in extreme cases, oil starvation of the bottom end (if too much of the oil is up top, under the valve covers). As for the reason previous owner deleted pcv, they probably thought removing emissions is a good thing but pcv really does a good job of scavenging acidic moisture and blowby vapors from the crankcase, it's your friend.
@@tylermontgomery24 I bought new cork gaskets for mine at least 12 years ago, still haven't installed them and still have leaks up there, lol! I'm getting ready to do it, took them out of the package for a look and noticed there's a steel grommet in each bolt hole. I'd bet the factory originals are the same, probably explains why if the cork shrinks just a little bit, they leak. So I'll either be using some "great stuff" crankcase sealer, or slightly reduce the length of the steel grommets (remove each grommet from new gasket and dress with grind stone) to obtain a little more clamping force. Good luck, enjoy your fantastic little pickup! ;)
No problem man! Me either, the previous owner had both sides plugged! Like wtf?!? Somebody pointed it out and said that was the reason for it leaking oil down the sides of the motor and running like shit! Lol It’s ran a lot better since I fixed it!
There’s not really much to report on. I mean it doesn’t leak oil all down the sides of the motor on the breather side anymore. It seems to idle a little better. Other than that not much! Haha sorry it’s not a more helpful answer.
Im glad i found this video, i thought it wasn't normal to have the hose go down the engine bay, if you were to replace ot with a sealed cap wour the engine blow up from pressure?
I havent seen any videos on replacing the ignition module and the high pressure fuel pump on a 1989 bronco ii lol nobody seems to know where it is ive seen some Gruesome things done to the The poor Truck. Some people cutting through the metal for easy access like how many times you need access the pump lol
Me either, ya cutting metal would be sketchy! Kinda like the old Chevy guys having to pull the whole bed off or cutting a hole in it to get to the fuel pump! Lol
The one in the tank is a low pressure and the one on the rail is high pressure, pretty sure..I changed both my tho and the control ignition module is behind the distributor held with two screws (with thermal paste on the back) not easy to get to but mine crapped out one day it would not Turn over. But yeah they’re not hard to do ,just a pain to get to
MAP sensor is going to be on the firewall mounted to a metal tab up top, it’ll have a single vacuum line coming off it. Right at the level where the hood sits while closed.
@@tylermontgomery24 No worries. This video was very helpful. I have an 86 ranger. I ordered some parts the other day and now after watching this I ordered what you showed in the video. ha ha. Thanks again.

Oh ok, that makes perfect sense! Thanks for the explanation, I’ll eventually replace those gaskets!

I got a 87 2.9 , thanks for posting, didn't really know about the the drivers side .
No problem man! Me either, the previous owner had both sides plugged! Like wtf?!? Somebody pointed it out and said that was the reason for it leaking oil down the sides of the motor and running like shit! Lol It’s ran a lot better since I fixed it!
Thanks for the demo. How about a follow up video confirming your changes made a positive difference?

HE TOLD ME EVERYTHING I NEEDED TO KNOW. Thank so much this really helped.

I’m not sure, possibly! haha
I miss the good old days.
Automatic chokes that didn't work. The smell of burning oil and unburned leaded gas. Oil all over parking lots.
I'd like to see how to change the distributer cap / rotor .... looks hard to get to
Ya seems like it! Haha
What’s the part number of the gasket for the breather?
If you mean the grommet it goes into, it’s a Dorman 42049. Hope that helps!

Not to hard to get the pump replaced it's an inline pump right under the driver side along the frame
Oh ok that’s good to know!

On the main top of the pcv were does.that hose go to thanks
It also goes to the air Intake, there’s a smaller inlet
I have a 1989 Ranger 2.9 liter V6. Been trying to find the MAP sensor. Do you know where it is? Thanks.
I don’t sorry
It's an air charge temp sensor, it's just below the idle air control valve on the air intake manifold.
MAP sensor is going to be on the firewall mounted to a metal tab up top, it’ll have a single vacuum line coming off it. Right at the level where the hood sits while closed.
what size hose did you use for the pcv valve?
I don’t remember, I’d have to measure it

Oh ok, no problem! Glad it helped!
I thought this engine used 2 PCV valves
I’m not sure man, mine only had one! Ha
