So my brother has a 1085 that the sleeves walk up and down and take out the head gasket. He had the engine rebuilt so it has all new parts still takes out the gasket after awhile. Is there a way to shim the sleeves to stop this? Anyone have experience with this problem? Its a 318 Perkins engine. Anyone know where to find a replacement engine or what combine engine will work? He said I can have the tractor if I fix it as he's sick of it. I think he's put 3 gaskets in it.
 
I did a search on the 1085 and seems these have a history probably you've already heard about the head bolts being the weak link. Here's a quote from the archives.

welding man is correct, Even though it is a perkins engine, one of the best engine manufactures in the world, they were built to MF spec"s and they didn"t put enough head bolts (studs) many updates, different nuts , studs, torques but you can"t fix stupid..or junk... Your check is in the mail--- really.
 
I would have the block sleeve counter bore checked, the gasket holds the sleeve down tight if all is correct. The block has enough studs IF they are retorqued when hot and the Lawson high nuts are used. I have a 318 out of an MF 540 combine that has the bolts, will get the studs from an MF S90 block I have. If the sleeves are allowed to move you will have trouble in any engine.
 
Sounds like I'll have to get it home and apart to know what's going on. It has a cab so it won't fit in my shop. Probably end up being in the spring. When you say counter bore do you mean it might need thicker sleeves? I'm not an engine builder for sure but have put a sleeve in my super 90. Thanks.
 
Both the A4300 and the 318 had 4.5inch bore. The sleeves were different, chrome plated ID bore steel sleeves on the S90/410 combine engines, cast iron sleeves on the 318. The 318 BLOCK sleeve bore is 4.640 while the earlier 300 block was smaller at 4.588 if I remember right. Both sleeves have a small step for the head gasket to hold them down, but once they have moved the block counterbore may be damaged. Most Perkins head gasket trouble is usually not retorqing when hot. Some 318s need the head studs like the early 300 block used. I have a S90 puller that I finally blew the head gasket this summer, but I expect it to after awhile with 35 plus boost pressure and well over 200 HP on the dyno. So next year there will be no head gasket or block sleeves either, then will find the next weak link!
 
with the difference in BLOCK BORE that diesel tech posted ,if the wrong sleeve got installed it most of the time would break below the flange and wind up in the oil pan, check the height of the sleeves above the block some set above the block others set level make sure the right gasket was used for which ever type of sleeve is used also install new head studs and make sure to us the proper torque sequence,i know of a small AC with a perkins that kept blowing head gaskets and it turned out to be the sleeves were to high above the block, i had sleeves installed in a 203 and told the machine shop up front to bore the old sleeves out,when I went to wipe out the #2 cylinder the sleeve came out on my arm,you could see the chip marks and hone marks where someone chipped out the old sleeve he ordered and automotive sleeve and bored the block to fit it,it never gave any problems,i've heard tell of a product that will hold them in place i've never used any though but would give it a try if the sleeve was a snug slip fit
 
On most automotive applications where a sleeve is needed to repair a block the block is bored, then the sleeve(s) are pressed in, then it is finish bored for the pistons, then the top of the block is machined so it's all flat. If you do it that way you can't easily re-sleeve the engine, but using the automotive type sleeves it should fix the loose sleeve/head gasket problem.
