Cleaned the top of the block off and it looks like this engine is sleeved, I didnt think the 5.9 was sleeved? I can feel the lines with my fingernail. Im scared that this block has been through the mill. This is a 97 12 valve engine.

Thanks but that doent help me alot.

Forrest Nearing

never seen anything like that, but it looks like it might seal well

BigBully

Im kinda skeered it wont so im thinking it needs decked but I still dont understand why it looks like it has sleeves.

Forrest Nearing

man, what I'm seeing looks like you've got a couple/few thou raised around the cylinders.

BigBully

Yes thats wht I am seeing But I still havent got an answer, are these engines Sleeved?

ratsun

No they are not stock, but if it was done right I wouldnt worry about it too much.

BigBully

They look alright but I guess what scares me is this engine only had 150,000 on it when it was pulled out. Makes me wonder what happened in that 150,000 miles that it needed sleeved.

mine looked like that too, I am pretty sure I compared it too the headgasket and it matched the metal sealing ring imbedded in the gasket.

I don't have pics, but I can tell you I see 45+ psi with 19deg timing and meth and no leaks yet, I check weekly knock on wood

Did the headgasket have a metal fire ring? I'm thinking it is just from the headgasket being compressed around there for 150,000miles. From what I understand the sleeves they would use to repair a 5.9 block you wouldn't get that ring like that. The repair sleeves are very thin.

Looks to me like normal wear from the head gasket. I've never had a CTD apart but Lots of the heads/blocks I pulled on Gassers looked like that. Just have the block deck resurfaced and put it back together with out worrying.

Dshiftff

yep 100% normal. just the wear from the oem headgasket firerings around the cyl's.

BigBully

Ok so the firering dont wear the top out but the rest of the gasket does? Because the rings around each cylinder are taller then the rest of the deck.
