245 D24 tic build
 
Some teardown with the short block and a lot of cleaning :

all the pistons are 77.48 (third size ) and are in very good shape
no traces of leaks under rings or something of this type:D
the cylinders are good too with the eye except rust on the top part because of the long storage.

the squirters are all good and here. just the n 6 that don't want to go out :(
i don't want to break it if i bang him .:mad:

next step will be to lighten and balance the pistons and conrods

the head is nearly done here :

Quite slow !

i'm on a d24 NA wich i'm going to present you soon.

i 've dismantled the pistons / conrods assembly, cleaned up and as soon i v'e finished the D24 NA i will lighten the rods and touch up the pistons.;)

i've retouched the head (combustion side)

i will show very soon too.


Thanks for your interest !

Here is a bit of what i did to the head after the ports job.

I broke the sharp angle in the inside valve perimeter to alow more flow at the intake and exhaust strokes.
I didn't touch the exterior perimeter part because sharp angles here helps a lot to share turbulences during compression and give a better mix between fuel and air.

a before and after shot :

michaelovitch,

What are you planning to do to lighten the rods? I suppose the idea is to remove some material from each one? Are you planning on balancing the entire rotating assembly?

Excellent work, and thank you for sharing. I saw a few of your videos on Youtube, well done.

Thanks for your compliments.

I try to share because those engines are so cool and not enough loved :p it motivate too !

About the conrods : i will remove material from the cap and from the pin bushing part (i don't know the name)
But i will make the oil reserve bigger first and remove aroud.

i will try to soften or remove the typical vein of the forging process and a bit of polishing.
i will balance all of them of course and give them the same weight

I don't know if the machine shop in town make the dynamic balancing i will have to see that following the wallet capabilities....
a set of main bearings is 250 euros yet + condors bearings 150 euros +gaskets etc....
i need a bore gauge to see if the block is really still good first :):)
