awesome build up mate

[quiksilv]

This weapon combination of choice was used for the head. Since I don't have an engine stand and the engine is just sitting free on a piece of timber, I had to stand it next to the wall to stop the whole thing moving/spinning around while I cracked the bolts. I know an extension plus small socket is probably not the best choice for torquing up a head so I will get some long sockets for that.


Then to my suprise we reveal this! A great big chunk out of piston one down to the top ring



Not to mention the stuffed combustion chamber!



Luckily I had planned for new pistons, but getting a new head wasn't what I had hoped - although I was fortunate enough to pick one up off the forums in great nick!

Been a while since an update - work is getting slower...

Block flipped over and off comes the sump




Removed oil pump


Removed rear oil seal and retainer


Still need to remove the oil pressure sender and coolant drain valve


I've also been putting off removing all the miscellaneous studs around the block and head as i'll be buggered if I know what length studs go where when I put them back in

[sbyder]

looks like you got yourself a shit motor. No offense but i hope you didnt pay top dollar for it...

[limbo]

its fine so long as he gets the block stripped down and hone, with new pistons and rings it will be good as new

[sbyder]

yeah i agree, but i'd be pretty pissed if I spent up to a grand on a dud engine. I just hope you either paid a small amount, or knew about the mess inside before purchase

[merc-blue]

Soo wrong.
There isnt any real damage, its noy like a new head cant be found for very little cost.
and new pistons were planned anyway, and pistons arent that expensive.

If you bought a engine for rebuld than then your bot buying it for consumables your buying it so you have the bulk parts, like seal housings and various bits.

Any serious rebuild throws away all the consubables any way,
From the initial engine i bought i have only kept crank, block and various housings and covers.
The head i bought has been stripped down will be built with new valves, guides etc.

Judging from the purchase of A/M rods and pistons, i dont think this was ever a new rings and bearings sort of rebuild but instead a build of a entierly new engine as opposed to rebuilding the old

[quiksilv]

Yep, as merc-blue has noted the engine was bought fully aware that it was in need of a rebuild so I wasn't too disheartened when I pulled off the head! It should scrub up nicely after i've sent it to the engine builders and I get some more time to work on it.

I hate to beat a dead horse, but if you were planning on turbo, and a rebuild and rods, and new pistons and rings, why didn't you just get a regular 7 rib 4AGE. We still dont know what you paid, but just for the sake of argument, a good 4AGE probably costs less than a blown GZE.

Anyway, Im still building my engine too, just as slowly. But its a 7A block with the 4A head going GTE. Good luck on your project.

[quiksilv]

Did a little work on the head and thought id post to show the project hasn't died yet

Pulled out buckets and shims



Using the infamous valve remover to compress the spring and lift out the retainers at the same time

Note the steam seals aren't pictured and are still in the head


Intake with one valve removed


Short I know, but that's all for now

[TERRA Operative]

AAAH! Thats my old ECU! Got top quality caps in that one! Used the best I could find.

I'll be following this. Cold be interesting for when my AE101 GZE gets built.

[quiksilv]

Yes thanks heaps Terra, should be perfect to get her running although i'll be using 440cc injectors so ill see how it goes!

[Talasas]

Looking good so far!

[quiksilv]

Some new parts just arrived. Many thanks to Warwick from Toyota in NZ !

Water pump


Oil pump


Gasket kit


0.5 O/S Pistons and rings

You going to do the washer trick to up the oil pressure?
I heard if you 'port and polish' the oil pump (really just smoothing all the sharp edges inside) you can get a bit better flow.
