Crank won’t turn

Hypothesis here will be fun.

 

Agreed,

 

due to the smell and the 'fuel pump problem', I'm guessing fuel wash.

 

By the way OP, if you dont mind where are you located? May be a TW member near by that could swing by to take a look. pictures are great but can't show everything.

 

So pull the caps?? I’m in Charleston SC. And yes this is my first time / this deep into a engine. You guys have been a great help getting me this far in to it!!

 

Easier right?

Pull one you can get to easy and see if that piston goes freely upwards.

Actually.......which side had the poor looking spark plugs?

 

Well unfortunately that's about 3000 miles from me...

 

That’s a trip for you. 20tacoma17

The caps..... that’s the bolts on the bottom of the crank right?

 

nah, just the rod caps right now

12mm 12 point socket.

 

Bolts on the crank and piston rods. Myself I would start with the piston rods that just don't look right as mentioned by others. Once you get each cap off try turning crank away from that rod.

 

Yep. Caps are on the bottom, connecting rod caps (2 bolts) on the bottom of the rods connecting the crank to the piston. Main caps (4 bolts and are marked with numbers), hold the crank in the block.

 

Leave those larger (15mm I think) 4 bolt caps alone for now. Those are the crank main caps.

 

Ok should I note how the caps are?also should I do one at a time?

 

Stick with the 12mm 12 point bolts and just them?

 

Look at connecting rod cap #2. There looks to be a piece of something between the connecting rod cap and the main cap.

 

I think they're notched to go back one way....keep track of where.

Don't take my word though, I'd have to go to the garage and dig out a Toyota rod to be sure.

 

By #2 is that the front side or back(clutch) rod

 

Sounds like an excuse for a spring time roadtrip!

 

All caps should be installed back into their factory location and orientation. What I do if more than one comes off is clean the base of the cap (visible portion on the bottom when everything is bolted up) and use a paint pen to mark them starting from the front.

 

From the front. It is on the front side of the main cap that is marked 2. Second connecting rod from the bottom of this picture. Disregard arrows.
