Michaelovitch- That cylinder head looks dang good. I didn't put that much work into mine, I just focused on having the ports lining up and smoothed out.

Thanks for your comment.

Detroit diesel alpin green is damn hot for a d24 imo.
Moreover it's not very far from the original color.

I did a flat black (boring) on mine.

If you are interested i did few vids on the head here http://www.youtube.com/user/michaelovitch?feature=mhee

To line up the ports with intake and exhaust is a very good thing yet.
Jason from this forum did it and he said it helps.

I don't know about you but i had several milimeters off on all the periphery of each port i found that was crazy as hell.

This is inside a d24 head :

Well I got my head assembled last night and torqued it down on the block. Here is a few pictures of my porting and my spring compressor doing it's job.

It's very clean !

You did a great job polishing the head

The tool is very useful.

Well the fresh engine is in and running. Oil pump primed up before I could get the injectors bled out amazingly. Only one problem..... The engine clacks like the injection timing is super advanced, but it is not.. I think my dial indicator that I used for measuring piston protrusion is faulty. I measured all pistons. They ranged from .027"-.032", according to the green book that would be a 1 notch fiber, thats what I used. The engine had a 3 notch when I stripped it though.... So time to pull the head,inspect and install a 3 notch. Anybody know of a good supplier of good head gasket at a decent price?

Have you tried retarding slightly to see if clacking goes away? Is your cold start operating/releasing fully? I'm sure I read that you were best to use the thinnest gasket you can where there is no chance of piston/valve collision?

Well the clacking is not from injection timing I'm pretty sure, I hoped it was and played with the timing. I disabled the cold start advance and adjusted static timing to .75 mm but still clacked and didn't run as good... Bummer..

I found out why my previous engine used oil. So the engine was rebuilt, when I don't know. Cylinder walls are in great shape with cross hatching, looks to have a mild "dusting". When I had the engine on the stand I looked closer at it, I could see the top piston rings! It has .5mm over pistons in it. So I measured the clearance for piston to cylinder wall and it had .024" WOW! I believe green book spec is .001 to .003 max correct? I think the engine was bored over 1mm and the assembler just threw in .5mm pistons. Well I'm going to finish hone it and see if my 1mm over KS pistons fit.
