1MZ-FE teardown

1MZ-FE teardown

Postby Smaay » Mon Mar 12, 2012 1:50 pm

This guide is for reference only. This is how I tore down the 1MZ-FE engine over the weekend. Here is the engine when I started. I mounted it on an engine stand and went to work.
Image
Here are a few shots so I can remember vacuum lines.
Image

Image

Image

Image

Image

Image

Image

I removed the power steering pump here. there are 2 bolts holding it to the block

Image

I took the engine cover off to show the VSVs and the fuel rails. It looks like some critter built a nest on the valve cover. There is another one on the back side of the head. I really wanted to slap the guy at the junkyard for telling me this is a good clean block.

Image

I unplugged the spark plug wires from the coils to the rear plugs

Image

These are the 2 spots there those wires are secured down. I just unclipped the clip and removed the 10mm bolt.

Image

Here you see the wires going back to the rear plugs. Using a needle nose pliers you squeeze the tabs together and the mount pops off. I also removed the 2 intake manifold support bars.

Image

Image

Image

Here I'm just making sure that I know where all the vacuum lines are going to the VSVs.

Image

Image

Image

Image

Image

Image

Here I unplugged the 3 coils from the wiring harness and moved it out of the way.

Image

These next 2 pics are the wire going down to the oil pressure sensor and crank position sensor.

Image

Image

Here I'm removing the passenger side engine mount.

Image

Here it looks like I just remove a harness ground from the intake manifold, you can also see on the left where I removed the EGR.

Image

Image

Image

Image

To get to the back injector plugs I had to remove the intake manifold. With those last injectors unplugged I was able to remove the wiring harness.

Image

Next I started on the AC compressor. I removed the bolts holding it to the block and this bracket

Image

Image

Image

Image

Here I removed the timing belt covers. Its held on by 10mm bolts. My heavy duty impact gun was able to break the crank pulley loose. Getting it off was another story. I had to build a makeshift gear puller to get it off.

Image

Image

This is looking down on top of the block, Here I'm removing the lower runners of the intake manifold.

Image

Image

Here you can see that weird bug nest.

Image

This is the lower intake manifold removed.

Image

Image

Image

Here is the right side of the engine, this is where the thermostat is hiding. The brass sensor is the water temp sensor

Image

Here I removed the hard water line and the thermostat.

Image

Image

Here I removed the water filler hard pipe and the soft water hose. You can see the 2 knock sensors here.

Image

Image

Finally got the crank pulley off.

Image

Image

Stick a small allen wrench in the timing belt tensioner and remove the tensioner.

Image

Image

Removed the timing belt. To get the black timing belt cover off you have to remove the cam gears. They are both the same gear except on the rear bank its on backwards. You can see the lip on the gear is swapped.

Image

Image

Image

To get the cam gears off, use a wrench on these “gears” on the cams to prevent them from rotating. Use a large breaker bar on the nut on the actual cam gear. The cam gear bolt is a 17mm.

Image

Image

Image

Image

Image

Image

Here the cover is off, its also easier to get off the idler pulley mount off now.

Image

I removed the cams and kept the caps in order. I also marked the shims and buckets for their location. I used the naming convention of Front Intake 1 or Front Exhaust 1

Image

Image

Image

Here is a close up of the Rear bank. What I'm calling the front bank actually has an L in the casing.

Image

Image

Image

I removed the front head. The head bolts are 12mm 12pt bolts and there is a single allen head bolt too.

Image

Both heads removed

Image

The cylinder walls, it was so dirty in this engine. I'm so glad I'm doing this rebuild.

Image

I remove the AC mounting bracket on the block and the front engine mount.

Image

Remove the timing belt tensioner pulley. You can see the water pump on here too.

Image

Remove this exhaust thing. Water flows behind it, so I'm assuming its used to cool down the exhaust.

Image

Image

Image

Here the water pump is removed. It was actually looking good, but I'm still going to replace it.

Image

Looking down, next to remove is this water line block cover. I don’t know what to call it.

Image

Image

Once I got that thing off I flipped the engine over and removed the #2 oil pan.

Image

Remove the oil pickup.

Image

The # 1 oil pan is held on by 12mm bolts and a few 10mm bolts at the oil pump and rear main seal assembly.

Image

Image

Rear main seal assembly removed.

Image

Oil pump removal.

Image

Image

Here is the first rod and piston removed. The skirt on the sides of the piston looks good. I can tell you now that the 1MZ-FE rods look about the middle in strength between a 1ZZ-FE and 2ZZ-GE. They are smaller than a 5S-FE and 3S-GTE. Once I go through all my boxes, ill make a good comparison picture.

Image

Image

There is a small dimple on the top of the piston to indicate forward. The rod also has a similar mark, here you can see it. It’s the tab right in the middle and bottom of this rod. The other side is just round.

Image

All the pistons and rods. Ill clean them up when I'm ready to re-assemble.

Image

Next is get the mains out. These are 6 bolt mains. There are 2 bolts on each side and there is also a single bolt on the sides of the block. It took me a minute to figure out what those were for.

Image

The mains are numbered so you cant mix them up. Looking at this main, the #2 that’s raised in an arrow pointing up is the actual number of the main. Not the number 2 stamped in the middle.

Image

Image
Crankshaft out.
Image

Here you can see the iron inserts in the block. I think you can get away with a .020 overbore with these inserts. After that you will need something like a Darton sleeve. There is plenty of room between the cylinders for that.

Image

Image

Here is everything on my tables. Lots of parts in there.

It seems pretty thorough although the links for the pictures don't seem to be working. Might just be me.

something i noticed. the bearing under the main cap was a #2 but the same journal on the block had a #1, has anyone else run into this?

yeah nice pics. It looks like the motor isn't in too bad of a shape. I've seen some with heavy sludge build up. Not much scoring on the block here...

yeah there was some dark tarnish on the lower oil pan, but the cylinder walls look pretty good.

After talking to Gabe more and more, im seriously considering a 3MZ with 1MZ heads. does anyone have a HP rating for that combo?

I am shooting for 265 whp. I think with the 2mz intake cams and 3mz exhaust cams and ported heads. I could do it. I am also planning a few minor tweaks to the internals like cryogenic freezing the rods to strengthen the metal the rods are made from. I will be using ARP head studs, rod bolts and main studs I am also doing some swaintech on the pistons and heads and also the bearings.
