NEED HELP: How to remove electrical harness?


At 7min in the vid (above), he struggled to get this plastic long harness off but did not really explain how to disengage this thing. It's so plastic and I know if I do it the wrong way, it will break.

Any idea how to remove it? See attached photo to identify part.

Red dust accusation on solenoid

Can someone tell me what's the dusty red accumulation around the solenoids which I popped out? Each one was original sitting in the cylinder above the spark plugs.

This is the same red earth dust that were found on the inner side of the alloy wheels. May be the original owner drove in red earth areas in Florida.

Could external dust elements go into the solenoid cylinders?

I know you're not going to like hearing this but the cold weather option on the CCV does more harm than good. If the oil/water mix in it freezes it takes longer to thaw out. There is a trick I use to get the fan back on. Wrap a piece of twine, heavy string or a shoelace around the nut on the fan. Then slide the fan and shroud into place, hold the fan so the threads line up with water pump. Pull the cord to turn the nut until the threads catch then let go of the fan and pull the cord to spin the fan on.

Here's a pic with it ready to go on.

Are you sure it's not rust? Those are the coils and the harness should be held in metal clips, the O2 sensor wires are there too. You have a different valve cover/ harness than the 50's kid.

I'll give it another try to figure out how to remove the wiring harness.
I looked at BavAuto, and he just popped 2 clips and it came off. This is seen at 12:40min mark in the vid.
It looked so easy for him.

Any suggestions on techniques to remove the wiring harness would be appreciated.
(See post #21 and #26)

This is what the cover looks like with the harness off. You can see the tabs that hold the plastic cover in place. Just pry them back one at a time when lifting it.
You can see the clips for the O2 sensors. IDK if there are supposed to be 2 or 3.

The case that the harness is in should be flexible enough to be able to bend and get out of that first tab, then you should be able to twist it out of the second one. should be simple after that. Sometimes seeing it apart helps determine how the fasteners work.

Thanks to jmo69, I got the wiring harness off but I still broke one of the plastic clips. Oh well.

Anyway, looks like there is some mayo on the corner where the CCV pipe is connected to and the engine internal components looked brand new to my eyes.

Some parts of the VCG is pliable but other parts are hard. Glad I changed it.
The gaskets around the cylinder shaft are definitely hard as rock.

You don't know what 'mayo' can look like. This was in the middle of a mid west winter after short trips. The mechanicals didn't look bad.

Completed the VCG replacement.
Test-drove it today for around 5 miles.

The STFT/LTFT did not improve. Perhaps, it was the lousy sealant I used. I have since ordered this one and will apply when it arrives.

I use the black RTV, mainly on the half moons and the ends.

I'm a bit late - would have suggested the often overseen Vanos gasket. Between the vanos and the head. I've had leaks from there in the past creeping back to exhaust. And messing everything below it. Also got 330ci at nearly 220k miles now.

Another smoke test would tell you if there are still leaks. Make sure all the wires and vacuum lines aren't caught under the lower rear corner of the cover.

VANOS gaskets = perhaps when I get in there to reseal the VCG

Thanks for suggesting.
