this question is for Jay, or anyone else whos been where im going.... I need to remove the intake plenum so that i can change the grommet for the pcv valve, and i want to know if theres anything i should be looking out for, or if its just a pretty straightforward removal (granted, a PITA) also, i'm guessing i will need gaskets for various things, so if anyone knows what gaskets i'll need, and what part # that would be awesome. Anyways... thank for any info

 

I can't help you with your question, but I was going to say get some pics of the removal/installation for it, and the install of the PCV.

It would make a good tech article I can put up here.
Oh, make sure you have your mechanic help you too

I'm also interested in the same things. I need to take the intake plenum off so I can replace my knock sensor. I'm thinking about getting my fuel injectors cleaned while I'm at it.

Well, have fun.

lol - thats the plan... shes also claimed that when it warms up..she will change my oil in a bikini... ( i'll believe that when i see it) and i will definatly put up pics of that.. lol

rofl - you mean how to let your girlfriend change your oil?

 

Yea this operation is not on my favorite list.

Things youll need from toyota:
Plenum gasket
PCV gromett
PCV valve
(2) Cold start injector supply tube gaskets (aka small EFI gaskets)

Definitally use rust penetrant on the EGR tubes (27mm or 1 1/16 wrench). Ive seen them get broken. Label all the hoses, or take pictures. Once you remove the plenum, use duck tape or similar to cover the intakes holes to prevent dropping someting down in them. You will need to drain the coolant some. Good time to change it. Disconnect the negative battery terminal.

Take your time.

LOL, I thought my girlfriend was the only one who called it "duck" tape!

Jay--will I need thos PCV parts for replacing the knock sensor? Will I aslo need the cold start injector tube gaskets?

Thanks, have fun.

I'm planning on doing this also, mainly to take out all the crap that has built up inside of it. are there any special ways of cleaning it?

 

The Intake Plenum Removal sounds like a cool new mod.

DH6.....

Would not be a bad idea to replace the PCV stuff since your in there.

Jay

 

Ok. Thanks. I'll see how much one will cost. Dumb question: What is a pcv valve? Is there anything else I should think about replacing while I'm under there?

Thanks again. Have fun.

IMO...given the PITA its going to be to take this thing off... ANYTHING rubber under there (coolant hoses, etc..) and the PCV should be done... a PCV valve is only 5 bucks... it would be better to do while you have it off...

 

PCV = Positive Crankcase ventilation valve

The pcv valve is a "one way" gate for any "Positive" crankcase pressure build up to escape into the intake manifold. Without such a device, all the oil seals that keep your oil in your engine would leak.

Id sure be tempted to take the injectors to a shop and have them cleaned. Napa does it for us here.

Jay

 

do they do the ultrasonic thing? If so, how much does it usually run for all 6?

 

Yes, I believe its like 20 bucks per injector or so.

Jay

 

hey thanks for the great info Jay.... when i get around to doing this I will take lots pictures so that everyone else will have an idea what they're getting into.... As for me, i just gotta psyche myself up and get in there.... I guess I'm just gonna have to take my time and pray to god i don't strip anything
