Default 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
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 .

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 :






pistons will come next

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 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
