I have put together a couple of gassers and am in the process of rebuilding my 7.3 idi turbo. On the gassers I used stp on the bearings and coated the cylinder walls with oil and give the pistons a coat of oil before putting them in the block. Is there any difference when assembling diesels. I have read that coating the pistons with oil can cause them to get carbon buildup behind the rings.
