Perkins 3 cyl diesel A3.152 Massey Ferguson 30B Smokes from breather hose

The piston pieces that were broken were above the top ring groove, only at the outer edge of the pistons

Thank you

In my case the liner on my used AD3.152 before I bought it (the best I can figure anyway) was too small and over time the #1 liner "worked" while the engine ran and eventually the liner lip broke off. The lip ended up on top of the piston smashing against the head and the liner ended up in the crankcase. Upon teardown, the other liners slipped out easily. Fortunately I did not pay much and after a proper rebuild with tight press in liners, she has been running fine for years.

Thanks Tom.
Some good ideas there.
I'll definitely keep them in mind for use.

G'day Dave grab the biggest implement you have stick it on and go to WORK the best way to run one of those in is to work it don't baby it around sure make sure it doesn't stay lugging right down in the rev range or runs at full rpm for long periods but work it hard in tha 1500 - 2000 rpm range and you will prob find it comes good. This is what I tell all my customers after a rebuild ( I do run them on my dyno for at least an hour before they leave ) and I don't bother with break in oils I use the same oil the engine is going to run on during it's life, have only had one failure in nearly 30 yaers and that was a new valve that broke at the stem.
