I am working on a Humvee bought on ebay, I think it was built in the 80's. I cannot find any ID Tags anywhere on the vehicle. The engine is naturally aspirated and smokes quite a bit. I am trying to find a service manual but need to identify the engine first! Any help would be greatly appreciated.
I am charging my camera battery now, will post pics today. I believe its a HMMWV, the owner thinks it was built in the late 70's... after research I think its a late 80's... it has a high water fording kit (not installed). I dont see any USMC markings anywhere... the left valve cover is stamped "GM". I did find some numbers cast on the rear of the block, just below the head: "F253" is on the right rear, and "10149599" is on the left. There is a mechanical fuel pump on the lower right and an injection pump (Stanadyne) under the intake. I cannot find any fuel filter anywhere between the fuel tank and the engine. Theres a tag on the rear of the right cylinder head that says "AERA". Thanks for the help.
I am thinking this is a HMMWV with a 6.2 Liter GM, I am wondering if I can get the injection pump rebuilt, (are parts available?) and where can I get injectors? Thanks again for all the help.
Ugh, looks like a HMMWV someone "civilianized" as a cheaper alternative to buying an H1. They probably removed all the military data plates in an effort to make it look like the more expensive model.
