hey, found a 7.3 int. from an ambulance, as well as a 7.3 from a wrecker. They are both similar and take 16quarts of oil. What is the difference between these and a 7.3 liter power stroke? Just wondering. Same bell housings??

 

The IDI and Power Stroke are two different engines, nothing is the same except the bellhousing pattern. The IDI is purely mechanical while the Power Stroke needs a computer to run.
Don`t know what the Stroke takes but the IDI takes 10qts. of oil. The 16qts you quote is, I would think, for the E4OD trans that both used.

 

Its the International T444E that is basically the same as a 7.3 Powerstroke.

 

The 16 quarts of oil is hard for me to believe as well but, the engine was rebuilt by a company called pmp or something like that. Sticker on engine sa " this engine requires 16 quarts of engine oil" Hard for me to believe my self. It looks more mechanical than a power stroke, but It is from a wrecker and all. A much larger truck really! Flat bed tilt/ bed wrecker with semi tires. What international 7.3 would this be if it takes 16quarts of oil? I will take a photo of the valve cover sticker if I can.

 

my 2000 PS 7.3 holds 16 qts, The spec is only 15qt's but I usually just dump 4 gallons in and call it good for 5000 miles.

Almost 300K and not an issue yet.

 

All 7 of our International T444Es take 19.5 quarts of oil.

First there was the 6.9 IDI International starting about 1984, it evolved into the 7.3 IDI around 1987 and was used till the T444E came out around 1994-95. International, to my knowledge never used a turbo on the 7.3 IDI in mediom duty applications.

 

Yeah, thats what truck that is. A t444E int. Nice flatbed wrecker. What is that classified as ?? A two ton truck? Can't believe that uses a similar motor to the 7.3 liter powerstoke! Pretty cool! Nice trucks really.

 

so a IDI and a powerstroke 7.3 share the same bellhousing pattern?

 

95-2003 7.3L powerstrokes ARE T444E's T444E stands for- turbo, 444 cubic inches, electronically controlled. They are the same block, but will have minor differences in turbo configuration, and yes both do hold 16qts of oil

The T444E/ 7.3 Powerstroke is one of the last true medium duty engines, as classified by the DOT. The 5.9L cummins is the other. The duramax, and the VT365 International (6.0L) are classified as light duty diesels. Why? Because of insurance and emissions.

 

Im talking 84 - 94 IDI 6.9 and 7.3 international engines fords had, do they share the same bellhousing pattern at the 95 and up 7.3 powerstrokes?

 

if the E4OD was used in 84 to 94 then it would be the same, as I do not remember the housings changing.

 

Is the ambulance a ford van front end? Then the difference will be in the the way the motor is plumbed. Those van fronts are tight, and a lot of components were reconfigured to fit in that small bay.

 

well, we are having to change some things from block to block. We will get her going again

 

Wow, i never knew that. I knew the 7.3 and 5.9 were in the same class

 

Yes. When ford went from the IDI to the PSD they used the same 5 speed on both.
