    Posted: 26 Sep 2020 at 12:10am
Hey everyone quick question that I’ve been wondering and can’t seem to find the answer or decide firmly on correct procedure.

On a wet sleeve motor like the 226 engine if my surface had enough pitting or gouges/scratch’s that I would want to deck it how is that done with the wet sleeve system.

Would you install sleeves then deck it to still allow some protrusion so deck block an extra 2-5 thousands to allow the sleeve to stick out that amount or just deck them both the same or sleeves flush with block.

Also is it possible to deck block without sleeves and then bore counter bores. I assume if this was done wouldn’t it throw off the location of the o ring seating surface from the sleeve to block.

Thanks and any info would be appreciated. I just wanted to know if I ever decided or needed to re sleeve this motor for any reason and the block was decked say 8-12 thousands would
The new sleeves need to be cut or shaved? What is the process involved in decking a wet sleeve?

Deck the block only enough to flatten/clean up pits then bore out the counter bores same amount.   Do nothing with the sleeves.

Sal,
The experts will be along shortly. 
My opinion is that the block would not need work as log as the sleeve protrusion was within tolerance in all seated sleeves.
 My WD45 block did not need any work on the top as the sleeve protrusion was checked and rechecked and scraped to get all the sleeve protrusions within tolerance. I believe it was around .005 inches.
Hope that helps.
I had my engine builder check out the flatness of the top deck and he said it was fine.
(note this is the same block I beat down over top of two stuck pistons years ago too. I digress, another story)
Regards,
Chris

In nearly 50 years of working on/overhauling those engines, I have NEVER had one decked. It would require decking X amount from the surface and then the same amount in the counterbores. Any pitting on the deck surface I have had is handled with sealer on both sides of the head gasket , good torqueing of the head bolts and retorqueing after a short time when stone cold.

Depending on the goals for your build, you may need to sleeve your block or upgrade to a closed deck design.
