Sorry about the crossposting, but I am trying to see if there are any gear heads here who are familiar with the Om314 engine. It is the stock 4 cylinder bus/truck engine and it is in my 1975 O309D. The engine itself is running well, but there is some type of explosion/ backfire at the engine when put under load. More later.

Many Thanks!
