Info needed please
We have a 1997 F350 7.3 turbo Diesel and was wondering where we can find the engine specs. Mainly the compression specs. It ran hot in the Rockies,(we live in South Mississippi) so it was not used to the altitude
. Have been told everything from rings, to head gaskets.
..One guy put it on his machine to test it and now it wont even turn over. Any ideas on this??? We use this truck to pull our 25' gooseneck, we have a Hotshot business and have to get this thing back on the road. We have since bought another truck, basicially the same truck just a 94. It is a 7.3 also, but the motor is different from the other 7.3? It is also a standard.
Thanks,
Cathy

From mid-1994, the Power Stroke 7.3 liter lasted through the end of 2003. This model produced up to 275 hp (205 kW) and 525 lb·ft (712 N·m) of torque in its last production year. The 7.3 is widely considered one of the most durable diesel engines in the industry. From mid-1994 to 1997, the engine was an non-intercooled model that had 90cc "single shot" injectors. These engines also had a 15º high pressure oil pump (HPOP). The turbine housing was a 1.15 A/R. There was no 1998 model year for these trucks. In 1999, the Power Stroke engine was given an intercooler. The intercooler cooled the charged air from the turbo making it more dense. The cooler, denser air would increase the horsepower potential of the engine, while also reducing exhaust gas temperatures (EGTs). The turbine housing was changed to a wastgated .84 A/R housing. The HPOP was upgraded to a 17º unit that could supply more high pressure oil to the HUEI (Hydraulic/Electric actuated injection) injector. The 1999 to 2003 7.3 engine had "split shot" injectors with the capacity increased to 120cc. These injectors prolonged the injection time to decrease emissions; however, some power potential was lost in this process.
