Ok I work as an addvanced tig/mig weldor and Have access to VERY large shot blasters at work that shoot Steel shot its accually an abrassive... A block (D-9 casting 1992 ) that I picked up recently has lots of scale build up on it would it be a wise Idea to send this through the blaster or not? Im concerned about getting steel shot inside the oil galleys... We have plastic plugs at work for pluging round holes and protecting taped and threaded areas but Im still worried about it if one falls out.. Any better ideas for cleaning this block up?
PS I plan on having it bored decked and alinged honed building a low HP stroker....

Theres nothing wrong with doing the shot blast method, but the stuff likes to beat up the smoothe and machined surfaces, so re-doing them all is a must!!

Be sure to thoroughly remove all the steel shot media from every hole and passage.
Chase all the threads in the block after its all cleaned.

You can also have it soda blasted and its much more forgiving on the metal!!

Thanks for the info do you think I should plug the lifter bores? I really dont want to have to have them bushed and machined. I know when we get steel plate out of any of the 3 blasters its warm to the touch and spotless they call it "shot white"

It looks like one of the motor mount bosses was welded back to the block in the first picture if this is the case I would hunt down a different block. If not I have had great luck cleaning rust from sufaces with a wire wheel attachment on my 4 1/2" angle grinder. Most machine shops will have either an acid wash or shot blast that they perform on all machined blocks.

LOL no this is what many engine blocks look like from the central Wisconsin area... I used some gunk brand engine cleaner tonight to get some of the greass of the block since the shot blast will not work well if there is built up oil on the surface besides pluging the $600 filters. the pressure washer took off alot of the flakey shnit but I will still blast it and see what I have left... More pics to come when done blasting.

It might just be paint or some other kind of build up in that area but it looks like a weld bead to me thats why I asked.

PS Did you notice where I am from? I have been lucky that all the used blocks I have had were oil leakers I guess.

Where in WI are you at I live right on WI,IL border in the middle of the state.

Wisconsin Rapids area near Stevens Point (point beer) This block came from Arena WI down by Richmand Center picked it up Fri afternoon and pulled it down today. I normally run 1/4 mile over to Kaukauna WIR... Yeah this was out of a 93 F350 that must of had good cover Gaskets damn it... seems when you get a motor out of an EFI veihcle they have more scale on them... And trust me there is NO paint on the block its just that nasty... I hope to have something left when I open the door on the blaster...

put the cam and lifters back in the block . the rest your machining , so it doesn't matter . also rear seal . could only sandblast the outside of the block . don't worry what goes in the oil passages , must be clean with brushes... blast or not

 

[fox501]

holly **** looks like you just pulled that thing out of a ship wreck don't thank I have ever seen a motor rusted that bad. good with it

 

[fireballferkey]

Its blasted and turned out better than I expected!

turned out ok.... Do ya have to have a line bore to have it decked?

 

[Lem Evans]

Yes deck it...it'd be best to have the main housing bores checked for size too.

 

[94ford521]

WOW! That turned out pretty good! Not a line bore, but it does need to be line honed. Or at least checked to see if a line hone is necessary. If its never been honed before, chances are its gonna need it.

 

[SLOWnSTEADY]

Those are some pretty, pink toe nails you have there! LOL

LOL yeah had the G/F working the camera... This block has never been machined came from a 93 F350 with a suposed 63K miles I know I have to have it decked since blasting the surface just was unshure if the line bore/hone was required when I pulled the slugs and rods out you could spin the crank with very littel effort and bearings had some signs of wear.

Hey that thing thing looks damn good!!
I noticed that it has two oil drain holes in the front of the block...did you drill those there?? because it did'nt have them in the 'dirty' photos.

 

[White Lightning]

LOL I'll bet that thing is lighter than when it came from the factory now!

Yes I did a few oil mods on it. This will be used in FFR roadster and may be cornering and stoping hard enough were they could be usefull. also added the screw in freeze plugs.

and yes I think the block is a lot lighter LOL.

Nice job Ferky! Now get that thing together and get it to RSD.
