My son has a 93 Dodge with the Cummins First Gen. Was smoking badly when revved when stopped. No power on road. He replaced the injection pump. Finally got started. At idle, blew dipstick out and oil. He checked and breather tube was pinched between starter and block. Badly need to get it up and running. Is there anyone in Macon, GA area w/expertise on this engine that could help. Not expecting free help. We do not know much on the internal workings of the Cummins. Never had one break before other than the infamous dowell pin on the 96 Dodge. Can reach me on cell at 478-993-6849 Dick Holden
