Ah, I see you have your IAC positioned 180degs from mine (tines up!) so I missed it. I noticed you have a manual trans. The 4 pin connector is likely the TPS connection for an auto trans. The auto TPS has both 3 pin and 4 pin connectors. It's fine remaining disconnected. You may want to tape the connector up to keep it clean and dry.

 

Will do.
I am now replacing my water pump that started leaking.
There are not alot of parts left until they will all be new.

 

You can buy those exact vacuum lines and elbows for nothing at the parts store and cut them to length.. just letting you know instead of buying high priced OEM parts. And that IAC and TPS are crucial PCM inputs. I reckon your idle is wild in park and neutral 😐. You need to plug those sensors in on the throttle body if they work. Then relearn the PCM after you complete the fixes. It actually looks pretty clean in your pictures somehow!

 

The TPS is an input to the ECM.
The IAC is controlled by the ECM and is therefore not an input.
A Renix ECM does not relearn anything. No need to attempt that.

 

Yeah, I forget to look at the year on the relearn procedure. Disregard that part of my comment, thanks for the correction. When the throttle body is closed the IAC is crucial*

 

The line at the rear of the valve cover (VC), is the CCV orifice. It connects directly to the intake manifold. See the red line on the pic below. The one in the front is the fresh air supply for the CCV system. It connects to the rear port on the airbox cover to provide fresh, filtered air to the engine block. The red line draws a vacuum and thus draws fumes, vapors, etc., from the VC and into the intake to combust. The "air" removed from the engine is replaced with fresh air from the airbox. If the orifice is clogged, or your rings are worn and have excessive blowby, you could build up a slight pressure inside and that will blow oil past seals gaskets, etc. Those grommets are likely the easiest path.

Next, The port on the front of the air tube (part of the airbox cover in yellow) is part of the EVAP system. That tube eventually connects to the evap canister near the oil dipstick. The air box cover actually has a plastic venturi right there to help draw fumes from the evap canister into the intake. So this is a "suction" line. If you had the front CCV port (fresh air, blue line) connected to the evap port on the air box (yellow line), then it would draw fumes rather than supply fresh air. This too could cause excess oil to leak at the front grommet.

I wasn't sure that I understood this correctly.
Uploading more pics to view.

 

It says my files are to large, how do I shrink the size?

 

 

Ok, that picture is a different subject.
I need to replace those, can the radius be a sharp turn?

 

 

oh my.. look how old your oil filter is..

but really I wanted to say.. do you have a diagram on the sticker - on or under the hood? ,mine is still readable from my 91 2.5L. its vacuum routing .. .. even my 79 merc still has it..but on that its on the front by the radiator



.

 

when I was uploading pics on my super long no start thread, I was using my laptop.. I found that my laptop saves temp files and so I have like 3 copies of the same pic at all times...
I deleted a bunch of stuff I didn't need.. out of focus pics etc.. and when I went to upload here again, it first opened the temp folder I still can't find any other way but was able to delete them all right clicking..

to make photos smaller.. you have to go into a photo editor and find the resize option

if youre on your phone it is basically the same.. a temp file somewhere and the 3 dot thing to find resize..

but its the temp file saving all the things youre uploading .. I cropped the following 1st photo.. its just to show you where about that temp folder is.. i have windows 11.. its under user in windows explorer..


the next pic just kinda shows resize... but really getting rid of the temp files is the thing that needs done

 

I did finally find the picture resize tool..
No, I do not have the diagram on my jeep.
Years old, almost no miles.

 

Your CCV hoses is still wrong. The one on the front of the VC goes to the back of the air box. See my previous pic with the color lines.

The one on the tube on the airbox goes to the EVAP canister. The evap cannister has 2 lines. The one towards the rear goes to the fuel tank. The one towards the front (no hose on it) goes to that port on the air tube.

You cooling system is another issue. Yes, you can use 90's. Folks make them using copper or brass. Looks like someone chopped the heater valve off.

 

OK, Thank You.
I will rearrange them. I do see now in your pic the yellow highlighted.
