hachiroll`s rust&lowcompressionrolla project

Looks like I am not the first one to work on this engine. On the exhaust camshaft bearing cap there is a different bolt.
On each camshaft bearing cap there is a different number from 2 to 5 and an arrow. Why do the numbers start from 2,not from 1 and why are there numbers ? To indicate the order of caps? In what direction should the arrows be arranged?
On my engine on the intake cam there is one arrow on no.2 cap and exhaust cam no. 4 cap in opposite directon. Is the order correct?
You can see it on the picure below.
Maybe stupid questions but it is my first engine rebuild.
Thanks for answers.

Yeap, someone messed with your caps
Arrow indicate to the front (cambelt). Number one cap is the big one with the camshaft oil seal in it.
You need to turn around No I2 E4.
That bolt looks ugly but does the job

Thanks for answer. I found everything about arrows and numbers in service manual today

Today I worked for a while on the engine.
On the cylinder head there is written 5-23N as you can see on the picture.
I doesnt look like it is from new. Does anyone know what does it mean?
And i broke my 1/4 ratchet extension bar while trying to loosen head bolts. What should I use to loose them? Do i need some special tool or 3/8 ratchet with extension bar will do it?

Don´t get exited, nothing special about the number in your cylinder head
You did not really trying to loose the bolts with a 1/4", didn´t you?
They got 30Nm and 2x 90°.
You are better of getting a 1/2" multitooth socket size 10, like this and make sure its as long and as slim as possible.

but what does the number mean?

When I mounted engine on a stand and turned it upside down this washer fell out. At first, I didnt know where was it from, but when I loosened engine head bolts one of them was missing a washer. Screw thread on this bolt is foked up, probably also in engine block.

Here is how the cylinders look like after removing head. When you look closer at second piston you can notice two round shaped holes, they are probably from valve locks which were left or fell in combustion chamber. Second piston is really clean, looks like he didnt work since fked up rebuild. And on third cylinder if you look very closely there is a spider web, looks like this one didnt work as well.
Head bolt washer in cylinder head, valve locks in combustion chamber, camshaft caps in wrong order, I would like to see the person who rebuild this poor engine and maybe theres more to come.
I couldnt get the crankshaft timing pulley of, I tried hammer, screwdriver but I wasnt able to get the foker of.
What should I do to get it of?

Screw look like this if you reuse them 1 or 2 times, the thread gets streched and won´t match the blocks thread, but there shouldn´t be any damage to the block. Every screw has its washer, take them out, cause they can get lost in the head
I hope you got new ones?

Pistons look that clean if they get in contact with water, hence your broken headgaket.

The damage to you piston is not nice, but ok, how does it look on the opposite head site? Grind down sharp edges.

I suggest use the "search" button to get the cam pulley off, the rust pretty bad, so more violence and heat is the way to go
You can get them new from Toyota for 20-30€ if I remeber correct.
