OK there is some pause needed to do an engine rebuild....

I was on a drift track, but the fun didn't last very long,

after 5-6 turns of fun some strange noise accured outa the engine bay.

it was sounding this like

:shutit:

OK, we had to remove the head from the block and found something strange...

We have tested the compression on all 6 cylinders and it had been fine.

Removing everything in the front

cam shafts removed

ARP head bolts removing

cylinder head removed and.... :blink:

Pic_101.jpg

in cylinder chamber 3 must be something wrong,

it seems to be some fuel problem, maybe due to failed injector

or something else, or maybe because of the 10:1 problem i had once (caused by the TPS)

watch the edges of the valve seat pockets :huh:

they're broken or melted away

Pic_100a.jpg

As for the engine noise we noticed..... watch the edges of the piston (up and down side) they seem pretty clean as like touching something (red arrows)

Also notice the small cuts in the exhaust valve seat pockets (yellow arrows)

Pic_108a.jpg

we reassembled the cam shafts to check valve train

Pic_102.jpg

but it seemed to be OK, nothing stucked or anything

Pic_106.jpg

But watch here cylinder 2 on the head, the piston definately comes in touch with it!

NOTE:

We have tested this case, so we have turned the crankshaft until piston #2 goes downway (pulling process), we took some rubber hammer and pressed on the piston *klack* :jawdrop: it really went down another 1mm :o

so it seems to be loosen somewhere in the conrod area.

So we have to find out another problem after removing oil pan and take another look...

Maybe somebody of you can give some comment what he is thinking about those problems how they can happen or anything!?

Well, so we had to grow deeper..... to the source of my problem....

OK, we have removed all devices from the engine (oil pump, water pump, alternator and stuff).

In the same run we removed the crank shaft and it looks like that I will

need a new one.

0,1mm of material is missing at the Conrod #2 eye at the crankshaft :ohmy: ,

so they would need to grind and polish, harden and reshaping everything,

in the second step I would need thicker bearings for the #2 conrod and I don't know if this is possible.

In the end I will need a new crank shaft. ;)

The engine builder told me that the cylinder walls look pretty good

just slightly honing is required.

And he was agreeing that the wasted oil I had inside in the beginning after

engine build in 2008 was the main reason for the engine damage. :(

The block is already honed, new valves should arrive soon, I will regrind the valve seats

and put on the new valves in the cylinder head.

Parts for engine rebuild are already ordered and should come here soon...

Just to let you know how my "RaceCar - Project" is going on...

Last weekend we could go on with some small jobs

put some body filler into the holes in the engine bay,

where could get water and dirt inside

100_0981.JPG

100_0983.JPG

Also added some zinc-spray on open metal areas

100_0985.JPG

100_0987.JPG

And I decided to turn the engine bay into silver-metalic colour B)

And we took care of the brake system, my plan was to remove the ABS block on some other place

about 10-15cm toward the front, so we had to cut that ugly brake-line-salad :duh:

100_0978.JPG

special care on the order of brakeline-numbers

Getting the ABS bracket into the same colour

bending them into shape

Before importing my IS300 from USA to Europe it must have had some terrible accident in the states

and got repaired pretty awful in some lazy workshop, so there is still the old radiator-frame inside,

that's why my radiator was sitting pretty crooked in place

100_1005.JPG

100_1006.JPG

So during this build-up process we will fix that bug also ;)

Great job Mike!

Belgrade is proud of you ;)))

HAHA, THANK YOU! *gg*

And I'm missing BEO so much since I'm sitting here in Germany.

Beograd nedostaje mi puno.... :crybaby:

If everything is fine with the Lexus this year I will do a ride down to Belgrade with it.

Much time got wasted in the workshop so I need some KMs on it, I'll let you know. :winky:

Looks like this will be a good one.

Just wondering, will the engine fit under those brake lines ? Also isnt that the exhaust manifold and turbo side ? If so could get pretty hot.

Good to see some good progress :D
