does anybody know where to get some just stock sleeves for the F22A because i think they are cracked on a motor I got laying around. I tried looking around and all I could find were the darton sleeves. I wasn't too sure if the price they gave was for one or the whole set of 4. I just want a stock replacement. A simple and cheap fix hopefully because the rest of the block is in excellent shape !!

I say we bore it to 86mm and see if its still there.

a sleeve costs more than an entire block.Comment

If it is a crack, I'd just replace the block.Comment

X2 throw in a 2ndhand block - It will work out alot cheaper.Originally posted by HondaFan81 View Post
Are you sure its cracked - I'm sure the above 3 posters would agree its pretty hard to crack the F22 sleeves.

It's my f22 block. It's his now.
Anyways, it has some pretty deep scoring in cylinders 1 and 2. I have no idea how that happend. All I knew until now is that cylinders 1-2 didn't hold compression.
Whenever we get an engine stand, I'll take the motor apart and check the pistons/rings. I'm just wondering if a 1mm deep scratch would cause it to lose complete compression.
I'm thinking there's more that we're not seeing.

Rusted block, or pulled straight from an assembled engine?Originally posted by d112crzy View PostIt's my f22 block. It's his now.

Strange for scoring to happen, what did pistons 1&2 look like, any traces of picking up on the bores?
1mm deep? Yes it will lose compression.
When you say complete do you mean 0psi?

It held 20psi or so, then leaked. The other cylinders held 160psi.Originally posted by evil_demon_01 View Post
This was my rebuilt f22. The block came from someone I didn't even know. Not sure how many miles were on it or the condition of it. The head was fucked, so I threw that away and used a rebuilt one. The motor was honed at the machine shop. The crank/rods were in good shape. The pistons looked fine, to me anyways.

Now thats strange, all this work, then a 1mm scratch has happened?Originally posted by d112crzy View Post
the oem ring gap is 0.20mm, if you opened this up a further 1.0mm (from the scratch) I would imagine the compression would be very low ( equivilent to a ring gap of 1.20mm)
A cracked ringland results in a compression of about 70-90 psi.
So It's highly possible the 1mm scratch could cause the low compression.
As to what caused the scratch
very odd indeed.

If the ring gap is to small it will score."Brought to you by Carls Jr."Comment

How so?Originally posted by totaldoughnut View Post
Is that because the ring would not be able to correctly shape to the bore thus the tips of the gap leaving the score mark?
Though that would lead me to see 2 score marks from each of the tips.
Don't mind me, I'm just thinking aloud.

yeah, it had 1 mark, about 3 inches long in the centerish of the cylinder(vertically). All ring gaps were specd out to stock.Originally posted by evil_demon_01 View Post

well... i think its a crack. But further investigation has to be done to be sure. Oh well... looks like we may have a boat anchor again !!

Because we already have this one and we're trying to see if its salvagable. Blocks around here aren't cheap. Plus...we'd still have to have it machine for either bigger pistons, or just a hone.
Plus, we're trying to figure out if we want to do anything with it just yet
