So, when removing the cam cover, the PLB hose that everyone says to watch out for as it is old and brittle and will break very easily has been broken... Now looking to replace it, I found the part (I believe) on SNG Barratt's website, however there are two... #AJ84880 for $28.32 OR AJ84879 for $58.75
I can't tell much difference in these parts, are they the same? Which one do I want?


Any help would be greatly appreciated, the sooner I can get the cat back on the road, the better! Further more, what is the proper procedure for removing this from the cam cover and and routing it to the TB?

 

#AJ84880 $28.32 :- is for normally aspirated engines,


#AJ84879 $58.75 :- is for supercharged engines,

 

Awesome! Thank you... I just wanted to make sure I was getting the correct one.
Have you had to replace this yourself?

 

I had made a temporary rubber fitting when my part load breather hose snapped (while installing aluminum thermostat housing). When the new part arrived I installed it without removing the intake manifold.

Routing it under the manifold is not terribly difficult, just an exercise in patience. One tip though, make sure it "snaps" into the connection at the throttle body. The original one pulled in and out of that connection suspiciously easily so I did some reading and discovered it takes a bit of force to get that connection to "snap" into place. I was nervous about pressing too hard, but then that satisfying "snap", and now I know its in there.

 

How do you get the connection off from the cam cover?

 

There is a small plastic clip tool that supposedly came with the car that slips into the connector releasing it. I have only seen pictures of them. For me, I used a pair of snap ring pliers, the kind that open out (external?).

I have been able to remove those connectors before by simple squeezing the sides until the little tabs spread out far enough to release. That is very unreliable though, and for some of those types of connectors it just never worked.

I have heard of some people using needle nose pliers; spreading the connector open by opening the pliers rather than closing them. Once you see how it connects you can get creative with a way to release it.

 

Is this the hose that runs from drivers side valve cover? I dont know that mine has snapped, however I see some hoses under the intake manifold / supercharger area that have an old coked up oil residue on them. I wonder if it is from this hose you mentioned.

 

It.s more likely old coolant residue.

 

Its definitely coked oil. Coolant residue isnt black and sooty / cake looking. I will prod around some and see whats going on.

 

It shouldn't be from the breather hose. If it were ruptured to the point of letting oil escape I would expect a P0171/P0174 indicating lean mixture due to air leak.

Is this the mysterious tool of which you speak?

 

Yes. As you examine the drawing you can see where needle nose pliers would separate the plastic just as easily as the correct tool . . .

 

I am going to get a smaller pair of pliers this week for exactly that... I am not finding this little tool for sale anywhere.

 

Look around at the quick connect hoses under the throttle body. That is where I found mind stored inside one of the fittings. You might get lucky and have one.

 

I will take a closer look when I get home, worse come to worse I may order the tool to do it

Found it between 10.00 GBP and $20 USD so far

 

I have found and am waiting for it's arrival a source for the part # 303-623.
Take a look!

I HOPE it is the correct unit!!!!

How did you get the Tee under the Car choke uncoupled? (small space).

 

My question as well! May have to remove the Throttle Body (really don't want to). Looking for a long 18" screw driver I can file the end to make like a chisel to cut the connector.

 

Induction tube is a 2 min job and 2x m6 bolts on the TB bracket.
Removing the TB is a 5 minute job, 4 bolts m8/13.
Removal of the centre plastic scuttle cover is a single plastic push clip.
Dive in and be patient not forcing clips, ask on here and if you can attach a picture of any snag items makes it simple for the forum to give you any answer.
Make the space and detach as it should, because replacing a cut part that way will be 10 times harder.
What are you trying to do?

Happy New Year!

 

I actually went to Harbor Freight and bought a 24" screwdriver, sharpened it, and cut the old breather tube off the Throttle Body. Now putting the new breather on was a pain too. Pulled the new one in place, centered it with the screwdriver, and pushed it on with a second long screwdriver.
Oh yeah, I cracked the connecter to the Throttle Body and Super glued it back into place. The Cat is running fine.
