I wish we could use the real words instead of acronyms...anyway I was looking to see what IDI really ment and came across this. I always thought my early 97 had an International engine in it...

The International Harvester IDI (from Indirect Injection) engine is a 4-stroke 8-cylinder Diesel engine used in International Harvester trucks, Ford F-Series pickups, and Ford E-Series vans from 1983 to 1994. The engine had two displacements: 420 cubic inches (6.9 litres), which was used in Ford trucks from 1983 until 1987, and 444 cubic inches (7.3 litres), which was used in Ford trucks from 1988 until 1994 (naturally aspirated) and in 1993 and 1994 (turbocharged). These engines were replaced in 1994.5 by the Navistar T444E (7.3 L) engine, which was also marketed under the Ford Power Stroke name.

 

international until 1986, then the name was changed to navistar.

 

So does my truck still have an International with a different name?

 

You have a Powerstroke 7.3L

 

It does say Power Stroke on the fender. I was just wondering if it was something else with a Power Stroke badge

 

same company, different name.

 

idi statement fixed in bold red (most still came n/a even in '93 & '94.)

technically all engines built after 1986 are "navistar international" engines (until ford built their own diesels in the latest trucks of course.)
"international harvester" split off into a different division for farm equipment at this time.since the change,it would be technically incorrect to call any of the diesels after 1986 "harvester".

navistar international
and yours would be DI (direct injection) not IDI.

 

I got it now...TKS!
