Here are some random pics to show that I have accomplished a little bit since the last update.

The empty engine bay.

General pic of her current progress.

The engine before any real dismantling happened.
Image

Inside the exhaust port.
Image

Goodies for future use. I need to learn to weld cause my Alltrac(Fiona) and Corolla(Milla) need some exhaust work.
Image

Dismantling in progress.
Image

A bunch of the parts.
Image

More dismantling.
Image

And the trans, all by its self.
Image

My next plan is to remove the clutch and flywheel, check their condition, and then get the engine on the stand for the full tear down to see where the knock started.

Hoping I have time this week or weekend to do that.

Unfortunately, yea lol. One of the PO's did a poor rebuild and I am out to do it right. This car needs to see consistent drive time. From what I know if it's history, it has seen maybe a 100 miles in the last 4 to 5 years.

Sounds familiar ... just a thought but consider upgrading yer turbo feed and return while yer out. Those flex feeds are prone to leak but you prol know that already.

Yea, I was planning on replacing it. After I dismantle and see what the rods/pistons and block condition is I am going to make a list of items to buy and then probably ask others for what else I should do.

Yea, I read that. They will be gone. I have a couple of the plates holding the valves that I am going to try and use to remove the valves and rod going through it.

Well, I dismantled more and here is what I saw.

The flywheel in all its glory lol. Still see the resurfacing marks.
Image

The clutch. One of the PO's told me it had some performance clutch in it. Not really sure how to tell. Also, does this appear to still have enough meat to even consider reusing?
Image
Image

The motor on the stand.........SO EXCITING!!!
Image

Chunks in the oil screen. Always a sign of a motor in top shape :)
Image

Here is the overall motor. I tried to move all 4 connecting rods at the crank and all 4 move slightly. I thought normally when you have a rod issue(rod knock), it's 1 rod... Assuming that the belief that the rods should have no play at the crank.
Image

Lots of sludge and debris in the oil pan.
Image

The head, which looks to be in great shape.
Image

I assume this is a cam part number(88360).
Image

And a question. I have a head from a spare motor and the head that came off my alltrac. The cams have one difference on the surface. The alltrac head has protruded metal around the cam at the back of both cams. The other head has a a metal notch protruded in the same area. Are they the same cams or are they something else?

Alltrac head:

Spare head:

Take a photo. Its hard to work out what you are describing.
... it almost sounds like you are describing the gen4 cams though.

What came off my motor. Circled in red on both pics.

The spare head I have.

Any numbers on the cams with the protruding parts ?

Not that I have found with some quick looking. I will try and search a little harder, but there is no number as obvious as what is on the original head.

So, took the pistons out. Piston 4 has markings on the top from metal making it there it seems. Plus it seems like one of the PO's marked the pistons with scrapping. Figure I need new pistons or use the pistons from the 3sge that I dismantled. Here is the shape of the pistons and crank. All 4 pistons had movement at the crank, so it was pretty mangled.

In order of front to back.

Piston 1:

Image

Piston 2:
Image
Image
Image

Piston 3:
Image
Image
Image

Piston 4:
Image
Image
Image

So, judging by the crank, would you say this should probably be reuseable after a machine shop visit?

I was honestly surprised not to see more carnage with all the crap in the oil pickup and pan.

So, now I need to start contacting machine shops and get quotes. My plan, theoretically, get a full rebuild kit, reuse the 3sge piston, 5s oil pump(anything needed to make it work) and look into cleaning up one of the heads. My goal is to try and do everything right, but obviously want to save on costs.

The goal is for a stock rebuild. The only performance stuff I plan for later is bolt on(exhaust, front mount, etc).

I would think the crank could be re-used. Machine shop can tell ya for sure though. May want to re-think the oil pump reusing ... hell that could be why the bearings look the way the did. that and the sludge in the pick up and pan ...

I actually planning on going 5s pump since I hear they have higher pressure. My first alltrac was always low on pressure and that concerned me.
