Hey,

I am not sure if I explained myself right. On the side where the exhaust manifold bolts on there is a little hole between cyl 2 and 3 always wanted to know what it is for.

yes i understand you but there is a same hole between 2 and 3 cyl at the inlet side to.

Yup, there is a corresponding hole on the opposite side of the head between cylinders 2 and 3.

I'm not sure about this, but could these two holes be for some lubrication/coolant circuit that never was used on the E series engines?

I start to port the head so see what i remove first because i don't know how to explain it.
there is the difference between two ports

and this is the original port

niceee! keep up the good work mate.

martin · Post by **martin** » Tue Sep 29, 2009 3:02 am

10X mate i will.
so today i replace the gearbox from engine.

i open the gearbox to fix it

because i have a problem with 5 gaer it doesn't engage correct.so here is the problem -the muff of 5gear.

there was wearing on one side

but it's cool because the muff is the same from both side and I just turn it up side down and think that will be ok

and the gearbox ready to be closed.

I'll continue the work about the car but just a little things because after a week i'll go to turkey for a little vacation.

cheers

Muff, eh? We call that a synchro(mesh) ring.

martin · Post by **martin** » Wed Sep 30, 2009 4:00 am

yes but this is not the ring that sinchronize the gear.the bronze ring sinchronize the gear for good shift.this is the ring that engage(mesh) the gear.

Oh, righto.

BTW, love your thumbnails. Big enough to have a look so you only need to click em if you're interested in some detail.

the gearbox is already closed.this 2 days I disassemble and clean the engine(parts)
and today was the day of truth.replace the crankcase

and yes there was a some problem.the thurst play(probably is not correct to say it like this but you will understand i hope)was too big .the bearings of crankshaft and rods was not too bad but i decided to change it and the pistons rings to.but this will happend after 2 weeks may be.there some pics to understand my meaningless words

find the difference

btw this

and this

and the shit

holy sh!t, this is a lot of crankshaft end play

are there any scores or so on the crankshaft, is it still within specs?

were there any noticable symptoms of this bearing failure while driving?
