Thanks CALIFORNIA KID,I finally found the numbers-just where you said they would be,but they were behind the exhaust pipe so I didn't find them till now.My engine had an oil leak from the exhaust side of the turbo-I thought maybe the turbo,but I took it off and ran the engine and the oil is coming from the exhaust.The engine ran OK,good oil pressure,but had some blowby.Now I think it's time for an in frame rebuild.I have done this before on a cummins,but this will be my first try on a cat.Any tips would be appreciated.The engine number I found is 7FB28474. The turbo number is OR6958.Any info about this engine and in-framing it would be appreciated. Thanks, Mark. One thing i would do and many guys dont think to do but pull the advance and check it and make sure and get it timed back to its specs. the 7fb is a good engine but the timing needs to be on the money.
