86 Suburban, warwgn's build.

[warwgn]

So how the hell does this work????

Not a scratch in chamber, a chunk that big missing from the top of the piston and it does not leave a mark at all??

Did the guy build the engine with the piston missing a chunk?

 

[piratexpress1369a]

all the other pieces were from the bottom end bearings?

 

[warwgn]

Yep bottom of the piston. Oh and the the block is bad, cylinder wall has a big crack.

Before cleaning the head

All the rod bearings and rods look good, crank looks good,cam is good, just need a block now and new pistons.

 

[piratexpress1369a]

that sucks big time

 

[bowstryder]

My guess is the block cracked first and let some coolant get in. Dang man. Time for an 8.1 mehbee?????
Seriously sorry about the engine fragging out on you though!

 

[warwgn]

Anybody ever had and engine sleeved? Was thinking of just putting a sleeve in this cylinder and moving on but don't really k ow much about it.

 

[warwgn]

So checking around I talked to a machine shop local and I think I am just gonna have it sleeved in that cylinder and then torque hone all the others. The sleeve install and bore is only $96 and another $20 to tq hone. That will make the block just as good as new, then I can get busy ordering parts and stuff.

 

[bowstryder]

You shouldn't have any problems with block after getting it sleeved. Just to be on the safe side, I would get the machine shop to thoroughly go over the block just to ensure no other issues.

 

[warwgn]

Headed for the machine shop

 

[piratexpress1369a]

how long before you get it back

 

[warwgn]

Not sure but prolly Wednesday. Been out in the shop cleaning parts and taking old pistons off the rods so everything will be mostly ready when I get it back. Waiting on the shop to call me and give me the all clear before I order new pistons just incase I have to get a new block, which if that happens would get .30 over instead of the .60

 

[warwgn]

Got my wife to help clean the intake while I worked on the valve covers.

 

[warwgn]

New valve cover look

Still need to put "496" on them but I am digging the red.

Looks great! Looks like a GM Performance Parts valve cover
