Hi Folks

So here's my situation.......

I have a 340 block sitting at .030. The machine shop advises that 6 of the 8 cylinders will clean up at .040. Unfortunately, due to a little rust pitting, he advises that one cylinder will have to be sleeved, and a second cylinder may or may not need to be sleeved (won't know until boring is commenced.) I am not interested in taking it to .060.

What are your thoughts on sleeving? Go ahead, or rethink the whole shootin' match? Labour on the sleeving is $250 CDN per cylinder.

Thanks

It makes them strong. Nothing wrong with a sleeve and in this case it would save a 340 block.
 
If you have a woman that is really loose 'down there', use the sleeve theory...

Shove a 12 lb ham up there and pull out the bone... Tight as a virgin once again... :D

for $250 per bore, i would do it.
local shop here quoted $400usd per bore.
same prob with mine, had a leaky head gasket on a project car i bought. compression was good and it ran good but coolant was weeping into the cylinders and two have some rust pitting...it blew some smoke once it was warm.
 
Have they sonic checked the block? My 340 is .060 over but was sonic checked and its not the gloom and doom people made it out to be. With Moly coated rings bore wear is minimal to none.

Man, that's gone up... about 5 years ago I had it done for under $100 USD per hole for all 8, price was lower for multiple sleeves. Haven't priced it lately, but jeez that's a hike.
 
Sleeving the bores will save the engine for future overhauls. When the sleeved cylinder wears out you just re-sleeve it!! I don't see any drawbacks to sleeving.
 
A sleeve will not hurt a thing, but that said, some 340s can go .100 over. I'd have it sonic tested. Then if you just want to sleeve it, go ahead. But as already mentioned several times, a properly installed sleeve actually adds integrity.
 
Properly sleeved are key words here. I would be careful about choosing a machinist to do this. I know diesel shops do this all the time. I would look for a shop that does both diesel and gasoline motors. Experience is everything.

"Experience is everything."


That's what she said!!!!!!!!!!!!!!!!!!!!!
 
Sleeving "may" put cylinder(s) on either side out of round. I'm sure your machinist knows about that tho.
I would go with the sleeves. Good piston availability at .040" ?

And since you're in Wisconsin too; don't forget shops that do Ag & tractor work also!
 
My #s matching 340 is bored 60 over, as were MANY 340 blocks back in the day.
I ran 12.5 pistons, and over a number of years sleeved 3 cylinders.
Shaved pistons 3 times down to 10.5 ish now, - still driving it today .
Wouldn't be #s matching without sleeves .

Agree, price of sleeves was $100 ea, just a few yrs ago.
Perhaps shop around .

My son charges $30 per cylinder to bore and hone. Add $50 to the total if you want it done with torque plates. Sleeves are $100 each installed. so your total cost here would be. bore and hone $30 x 8 = $240 + 50 for torque plates + 200 for 2 sleeves = $490 for labor for the complete job. Add for pistons and sleeves of your choice.
 
Thanks for everyone's input. I have advised the shop to "go ahead" with the sleeve (s).

Great pricing.......We're not so lucky up here.
 
My 340 is bored 80 over.
