blaster top end rebuild

[MikeB]

So I called my local machine shop today about boring and honing my cylinder head and they said they can do it or it might need sleeved. And said something about sticking a magnet inside of it and if it sticks they can bore it if it doesn't it has to be sleeved. Also how do I know what size piston is in it and what size to get next

 

[MikeB]

Here are some pics if I'm not mistaken the last 3 numbers are size right which is 75mm correct? Also what do you guys think about what you see does that Piston look normal

 

[MikeB]

Also if this is 75mm that means I only have one bore left right?

 

[MikeB]

Answered my own question it's a 67.50 mm weisco piston. What would be the next size

 

[Larry's Shee]

It looks to me like 67.50 which is .060" over. I'm only seeing 68 & 68.25 on Vito's site in wiseco

that shop doesn't know blasters if they're asking about nikaseal linings versus steel sleeve.

67.75 is the next size

Yeah I found some 68mm which I think I'll get. That 75 had me worried I thought I was going to have to get new everything and start over. What was the price on those at vitos? And was it a full kit with good gaskets?

 

[MikeB]

Yeah they build race cars and things like that I have no doubt they can do what I need as far as a bore they come highly recommended where I live. I would love nothing more than to send my motor to ken but trying to save money and do it my self

 

[MikeB]

Good price on those pistons is that a full kit with gaskets or will I have to buy separately. Also what do you think of that Piston I posted a pic of is that normal to be black like that

 

[MikeB]

Also that half a black ring on the cylinder head on the other pic what's up with that

Looks like a oil mark. Maybe burnt oil residue.

 

[MikeB]

Yeah but why is it on the top of the cylinder head and why only a half ring

Gasket's aren't that much extra. Only use OEM or cometic brand base gasket's. Cometic sells sets, but sometimes it's just easier to get all the parts in one package.
