For sale is a brand new, OLD STOCK Onan engine head. Military surplus. They are supposedly for Onan DJC, DJB or DJE. The number stamped on them is P2246. It also has a number 1874 in ink.
I started a discussion about it on smokstak.com, see what people have to say about these heads.
Only one head is included in this auction. I HAVE ANOTHER IDENTICAL HEAD and NO MORE. The total number of onan heads that I own is TWO. The second head will be offered to the highest bidder at the winning bid price, provided that the price is sensible. You need ONE head for DJB and DJE, and TWO heads for a DJC.
I own an Onan DJE genset, and these heads look like they are an exact match.
