Engine Control Harness & wire connectors

[BrianD]

I am under the hood of my 98 Pathy preparing to change the passenger side valve cover gasket.

It's leaking and it stinks of burnt oil after running great for 312,000 km's now.

I've started to clean up around the valve cover and wires so I don't drop dirt into the engine & clean out the Phillips head screws so I can get the screw bit deep into the screws without stripping them. So...I'm trying to disconnect the plastic wire connectors that are pushed onto the brackets that are welded to the valve cover. The 1st one came off the cover easily and then I tried to separate the connector into 2 parts and snapped a pc of plastic off from the under of it. I DON'T want to break anything more if possible.

I lukd thru the 4" thick factory service manual and there's nothing I can find on most of the questions below..

 

So my questions are:

1. How do I separate the plastic wire connectors from the brackets on the valve cover?

2. How do separate the male and female sides of the wire connections from each other without breaking them?

( the light grey ones near the firewall don't have the same release tab as the front ones)

3. It may be a stupid question but.. does the rubber hose at the back of the VC hold antifreeze? I think it's an oil vapour tube yes?

4. If I damage the rubber tubes at the front and back while removing them, can any type same size rubber hose be used as replacement or will I have to order them O.E.M.?

I did get the O.E.M. VC gasket but NOT the rubber grommets/ washers cause they cost almost $7 each.

5. Was this a bad choice?

6. Do I need to apply gasket glue at installation?

7. What type shud I use?

8. Shud I be disconnecting the battery before doing this so I don't screw up the ECM?

9. Too many questions?

I've already labelled the connectors a with black Sharpie so I don't misconnect ( is that a werd?) them.

I wanna do this right the 1st time & I HOPE I don't have to do the driver's side.

Thanx in advance.

I just priced the 2 evap/ vacuum hoses for this passenger side valve cover - $70!!!! Where can I get them for less? help!

I bleev the part numbers are 11826 +A and 11826 +C

[BrianD]

I just got 1 hose that U cut to fit both ends of the passenger side Valve cover.

Nissan wants $70 for these 2 hoses.

The one at the rear is 6" x 1" x 5/8" I.D.

The front is a 90 degree elbow and is 4" x 1" x 5/8" I.D.

 

Get AC DELCO part #16198M - or GM# 88907438 - same part ..2 numbers.

It's whopping $10.10 which will do both.

You are welcome.
