As you know I'm basically rebuilding my top end. So tonight I finally got started and took some pics. It will be slow going as I'm not a mechanic and started before Drkgypsy made it over(man is he going to have FUN piecing this mess back together with me ). Parts on order, machine shop lined up. Let the dismantling begin.

Angles of the engine area:




Room to work in:



Goal to remove tonight:


Success:


The mess:

 

Parts are ordered. Going to a larger valve on the heads. Downey headers and new HP exhaust. 2" body lift and I just found out I'll be getting an early B-Day gift of new skyjacker shocks (currently all 4 corners ride on economy monroe shocks -- Not designed for my yota). Love ya sweety, no, not you guys on the forum...Nothing personal.

The Project has began

-=Morphine=-

EDIT:::
Is it common for this gasket to be cracked into 3 pieces when you remove the air intake manifold?

 

What is a top end rebuild? Not sure about the gasket, never had my 3.0 appart that far before I sold it although I needed to because the valve cover on that side leaked. Doesn't look TOO bad but sill a lot of work for a valve cover!

 

Bike4miles, as the title says, that's what I'm callingit. Machining the heads, valve job, adjustment, new gaskets, hoses, etc.

Basically Cylinder #6 is shot to hell and the other 5 are weak. Hope that explains my intentions.

-=Morphine=-

 

Yes. I've removed my plenum many times and it's always in 2-3 pieces. You oughta see what my engine compartment looks like right now. Good luck dood!

 

Great Pics! This weekend, I'm going to start doing the same thing... My 91, V6 is showing a knock sensor code and I finally decided to take-on the project in replacing both sensor and wire. Thanks

 

Ok, got it. Hey ChickenLover, is that your radiator I see still mounted? How did you get all that stuff out without smashing it? That's always the first thing I take out.

 

Nah, the radiator was the first thing to go. That's just the 'thing' that sits in front of the radiator. Sorry, I can't think of what it's called.

 

AC condensor is whats still mounted.

 

Midnight wrenching or the Haynes manual I'm using....but something doesn't seem right. Alright, Air intake manifold (plenum) is off, so are the valve covers for both sides. Next the manual says to remove the "intake Manifold" between both sides. Ok, however I still have the timing belt and cover and everything else on up front - minus the fan and shroud still on. The Intake manifold appears to be connected to these items. Am I wrong? Should I remove the timing belt and upfront pulley's and belts, then the intake manifold? Anyone off tomorrow and want to come up and help? Pizza and soft drinks? If it gets done BEER!!!

Please guide me O'ye wonderful and full of the Yota knowledge followers of yotatech.

Get your T-belt off. One quick tip also: Make sure you replace your knock sensor and wire! If not it will almost gaurenteed to throw a code 52 after you get her back together. There's many ways to dismantle a 3.0, the 1st thing I would have taken off was the T-belt, starting upfront and moving backwards. It's pretty much up to you. The advice I use to give to people when taking a 3.0 apart was: take pictures and get yourself some pieces of cardboard, the cardboard was for to put the bolts from the heads in order in which they came out,and other bolts (unless your replacing them), That way you'll exactly where they go. Your doing a fine job! Good Luck!

 

Agreed, and yes that lower intake plenum has the #2 idler for the timing belt attached to it. Pull the timing belt like nunsa said, (after setting the engine to TDC) then attack you cam gears (goodluck hehehehehe they are nasty SOBs to get off) only then can you take the rear timing covers off, then the fuel lines/rails/injectors, then lower intake.

I did find a place online that sells new heads that are ported polished with oversized intake and exhuast valves, AND have 4 cam profiles for this engine!!! The heads come already set up to go. The cost however is 1200 + 600 core charge!! :eek:

 

Ok, timing belt and accessories are next. I already set TDC and marked it, so I'm good there. I've heard from many sources to replace the knock sensor and wire now so that's been added to the list.

Bumpin' yota - Out of my price. Thats almost the amount that this repair is gonna cost me. I would like to check them out if you have a link. Curiosity killed the called.

I have carboard and post-it notes labeling everything and my digicam is going crazy. Putting here back together is going to be a PITA.

Is there an acceptable number of parts that can be leftoff and she'll still run fine? j/k

You'll LOVE your skyjacker Shocks (I do) DOnt foget to replace the steering stablizer while your at it.

 

Ok, with so much torn off the engine I decided to take a stab at some body work while I'm at it. In tearing down my 3vze I've found the fuel injectors (2 of them) were held to the electrical connector with zip ties. Completely fouled up I'll be sending them for a cleaning and comlete flow test to Cruzinperformance. Heads will be going to the shop on friday. Here are some more pics...

Is this the knock sensor?

Niiice! Good luck with that crank pully and the cam pullys!

That website you wanted that has:

Performance Heads w/4 cam lobe options
Big Bore TBs
Forged cranks
Forged rods
Cast race prepped rods
Forged pistons
Moly ring
Head Studs ----- something you and I should get
3vze STROKER KIT!!

That site gives me ALL kinds of ideas!!

EDIT: Whoops forgot the URL...LOL

Anyone got a few grand I can have?

 

PS - yes that's the knock sensor. You should REALLY change out those steel freeze plugs....I bet they are rusting like a mofo...

 

Morph,


Sorry man I forgot to send you this really cool web site. You can print out the steps for taking apart the head and many other things. http://www1.autozone.com/servlet/UiB...3d8017957f.jsp

it is should be one line in the address bar with no spaces and type it just like you see it here. I have printed it out a couple of times (only the part for the 3vz) and have the pages real handy while I working. I have checked them against the chiltons I have; and for the most part excatly the same. the printed pages are cool cause I do not have to worry about greasy finger prints on the import parts of the book.

Your tracking right...good luck

 

Replace knock sensor and wire when doing t-belt replacemnt?
