12H-T question...
Anyone know if this engine uses cylinder sleeves?
Is a 12H-T rebuild particularly expensive? I would imagine that if the cylinders don't require boring (if it has sleeves) then perhaps not as much. Thanks! __________________ Time flies like an arrow. Fruit flies like a banana. - Groucho Marx

12HT's aren't sleeved AFAIK but even if they were as the 3b is, there is still machining costs to factor in which can add up easily to 1000 or more. Add to that your parts cost and it will be a costly rebuild. On the positive side, you'll have a kickass engine that you can pass on to your kids.

The 12HT AFAIK is not sleeved The 12HT kit is not substantially more than a 2H last time I looked. EDIT $1275AUD IMO you need to machine the bores if your using a rebuild kit to get the crosshatching pattern back on the cyl. The items that could push the cost up are a turbo rebuild or pump rebuild if they need doing. The machining should include the manifold and flywheel for the best job. __________________ HZJ75 cab chassis 95 model ,stocker FJ73+1HZ Diesel NEW GEARBOX 1HZ =same power as 3F with 30% better fuel economy 2in Dobinsons lift.Powerdown adj shocks 33 in BFG A/T HJ61 with slidin windas  regrettfully SOLD:(Volvo 740 GL |

It's not factory sleeved, but you can put a sleeve and back to the factory bore if it's needed .. actually if where my engine ( you can donate if you want
 ) I just go with the Rosco route .. no sleeve and bore it if where necesary with over pistons ..

There is a club member that got the kit from 4- Wheel Auto for his 12H-T (ATEB) did the rebuild but got the machining done somewhere? for the sleeve installation.
