What's The Proper Name Of This?

[ajohnson928]

As you can see in the pictures the rubber grommet that goes on the valve cover is gone and this hose was just stuck in there.  Anyone know the part number or at least the proper name for the part?  It's the larger opening in front of the oil fill cap.  And as always if you happen to have one laying around PM me.

 

Thanks

Crank case vent or emission hoses or vacuum harness depending on retailers.   I'll get you part numbers In the following post. 

 

Also based on how nasty that valve cover looks on the exterior and what little we can see on the interior you may want to remove it and clean it up inside and out.

part numbers are listed on these two forums.   The way I did it was way better in my scenario in my opinion then the stock boot that went there as I eliminated all the egr and was looking for clean.

Ended up taking in the valve cover to napa and getting generic pieces for the vent. A grommet and a plastic 1/2" 90. Napa parts 6301047 and 6301070. I swapped the vacuum line and vent line so my hoses were shorter.


and cut my towers to a pseudo Cruiser mod. As mine already had a factory 1/2" hole compared to the '88 You can see the difference in height, I only removed 3/4" and maintained the same angle of the cut. You can see in the picture where the 89 had a factory drilled hole in the back vs the '88 sitting next to it for reference.







I decided after aligning the cork gasket that I'd rather not screw with the cork and have to replace it in two oil changes so i picked up the felpro one piece blue one.

I got a full replacement vacuum set on e-bay 2 years ago. I spent about $22.00 with shipping. Prior to that I just went to the hardware store and put together about $4.00 grommets and hoses to achieve nearly the same function. The new vacuum lines do look nice, the same as stock.

So much for using the "spoiler" function to try and keep the post clean.   Cruiser I'd already posted your exact post as a spoiler earlier.  

[ajohnson928]

Now I've got more concerns because the vacuum connections in your last picture are different than mine.  The large hose on my MJ is in front but in rear on yours.  The small vacuum hose on mine goes up to the little solenoid on the firewall where you have a small red line running to the throttle body.  She runs so I guess it's not bad.  I just wonder if the PO messed things up or if mine is different from the factory.  Hmmmm.

 

As far as clean up... I'm planning to do that soon.  I've been too busy fixing major things.  I've only had her for a month or so and I only have some weekend time to turn wrenches.

 

Thanks for the part numbers. A lot of the vacuum hoses under the hood are looking dry rotted so I was planning on doing a lot of replacing.  I'll just get a kit and knock them all out at once.

Not a big deal.  if you read through that post I copied over you'll read that I changed the locations of mine based on how I needed/wanted to run my lines. And no difference in operation is noticed.  As the other end connects to the air intake(at air filter).  

 

The small vacuum hose on mine goes up to the little solenoid on the firewall where you have a small red line running to the throttle body.

 

This is not correct.   That little solenoid on the firewall is you Manifold Air Pressure Sensor, It is to be connected to the throttle body directly or as cruiser did atleast connected to the intake manifold.   If it is connected to the vacuum hose off the valve cover it is not metering the vacuum of the manifold and probably causing you not to run very well, also questioning then how or if they plugged the port on the throttle body.

 

She runs so I guess it's not bad.  I just wonder if the PO messed things up or if mine is different from the factory.  Hmmmm.

 

As far as clean up... I'm planning to do that soon.  I've been too busy fixing major things.  I've only had her for a month or so and I only have some weekend time to turn wrenches.

Look in the DIY forum there are pictures people have posted of the entire vacuum routing from factory.  If you're maintaining your EGR there are a lot of lines that are critical for it's function.   If you look up those part numbers from Cruiser54 they look like spaghetti because there are so many lines.   If you look at my lines it's about as simple as you can get.  You can see I have two ports plugged with red caps in the front.   There is one other vacuum line that pulls off the back of the manifold that goes to the heater control and your axle disconnect controller.     Any vacuum leak will cause this thing to run at a very high idle.  Your resting Idle should be below 900 rpm.

No personal experience but I've read and heard of several people having issue with those prestone inline coolant flush fittings.  Our system runs very hot and that plastic fatigues very easy.   Just a word to the wise that it is plausible that will break and blow out on you. 

[ajohnson928]

I'll research those posts and refer to some manuals to get it figured out.

 

My idle once warmed up sits around 500.  I am planning to clean out the IAC to get it smoothed out some but generally it idles fine.

Thanks for the tip.  The PO put that in.  I'm planning to do the change over to an open system at some point so I'll eliminate that at that time.  For now she sits solid at just a hair over 210 once warmed up.  Even sitting in traffic with the AC on.

[ajohnson928]

Actually I was calling it from memory and was wrong.  The vacuum hoses are routed as you said they should be.  And rereading the first response, I'll be pulling the cover and heading to NAPA.  Thanks for the input.

splurge on the felpro gasket.  You'll hate the cork if you ever use the felpro.
