3.4L Teardown & Turbo Install

Sub a dub dubbed

 

Excellent work so far! Can't wait to see the rest. Sub'd!

 

Subd!

 

Can you point me in the direction of someone who knows details on this? The guy helping me right now is the engine master, I'm really more on the suspension, fab,and welding side of things.

If I can get a full standalone for that price that people have used before, SOLD

 

Best bet might be to contact @Torspd , @Lucario Runner or one of the other speed gurus here, they probably know a guy. I unfortunately dont off the top of my head

 

Couple days worth of updates coming. I got waaaaaaaaayyyy too drunk Thurs night and kinda slacked off, but we made good progress otherwise.

Start off with the honing. Greased the walls with 90 weight, definitely an art to this whole process. I prefer the stones to dingleberry style, all about preference though.



Before and after shot, happy with results. Cross hatches still look good, all remaining residue will be taken off with a wire wheel. There was only 1 cylinder with potential issues, the lining is scarred pretty bad but appears to be out of stroke, we'll see!

 

Grease the new bearings with assembly lube, get ready for the crank install. Before & after.

 

Bearings installed on girdle, lube her up and ready to go.

 

Now, let's discuss this magnificent tool. Battery powered load cell on this torque wrench, gives you visual & haptic feedback as you get close to your desired torque value. Lights from green-yellow-red. Vibration increases as well in case you can't see the location you are torquing.

 

Most of the bolts on the 5VZ call for ft-lbs + XX° of rotation afterwards. This wrench does all the math for you with the degree settings.



Girdle installed.

 

Pound the wrist pins out of cylinders. Rebuild kit I bought has new pins, pistons, and retaining rings.



Clean these bastards as well as you can, time to start worrying about contamination once you get into cylinder install territory.

 

This is where my pictures/documentation of cylinder makeup & installation should go.

The distinct lack of said pictures is due to combination of Michelob Ultra, Guinness, and Costco brand rum.

 

Hard to see in 1st picture, but valve guide seals need to be replaced. Twist & pull with hose clamps, you can see what I'm yanking on in 2nd pic.

 

I also don't have any pictures of valve stem assembly or installation. Neither of us have cussed that much in a long time. The keepers have to ever-so-gently fit down in just the perfect orientation, while trying to keep the valve spring compressed (I'm guessing somewhere between 150-200 lbs of force). And of course when you slip off the spring plate, all the tiny pieces go flying across the garage.

We spent about 20 minutes looking for 2 keepers, both of which were hiding in the head the whole time. This picture illustrates my feelings on yesterday's activities.

 

Valley is made up and installed, ready to put manifold together. Knock sensors are pretty worthless in my opinion, but I put them back on anyways.

 

Put the manifold back on and this is how she sits as of lunch on Sunday. We will finish her up tonight.



Also got my diff drop installed. Took maybe 7 minutes?? Nice and easy compared to every other GM diff I've had to mess with. I'm definitely a Toyota convert after doing this build.

 

Remove spark plug tube seals in valve covers. These things had 190k miles on them, and let's just say they were a little "crunchy" when I tried to pull them off with the correct tool. Cheap ass harbor freight screwdriver kit to the rescue.

 

mmmmmm.... rebuilt supercharged 3.4

 

That wrench probably cost more than my truck...

 

Looking good. Sub'd
