Ford rates the 7.3 IDI at 300,000 mile longevity before rebuild, how many have gone over 300,000 miles on a motor before rebuild and how long can they go.


TJC claims to have one that has never been into majorly with 500,000 miles on it. R n D's Justin told me at about 240,000 is when the rings start to show wear ?


Appreciate the time to reply.

 

Sooooo, why ae you asking this on the powerstroke forum

 

Hey Realslowww, like Moose said. You should post on the IDI forum. A lot of us have 300k plus on our PSD's but they are a differerent animal than the IDI. we only make 17:1 compression for instance. I think your's is more like 23:1, so they wear differently. Post up on The IDI forum and you'll get some good info. Good Luck

 

Sorry I made a mistake because my handle sums it up, somebody please get this thread where it belongs so it doesn't stink the real diesel forum up.

 

We don't mind off topic here, in fact its a very common occurrence.

 

OK, I'll bite. Why does the IDI have so much more compression? Is it because ours have a turbo, got to make room for more air?

 

Injection system has different requirements.

 

I think your both right.

 

I only know this because put a supercharger on my GTO and got a lesson from the speed shop I brought it to. I'm not a PSD guru. That's why I ask you guys stuff......... However, here's what I know. compression is lowered on engines that are equipped with any forced induction. From what I was told, forced induction on high compression engines will make stuff break. Not enough room in the cylinder for all that fuel & air.

 

I knew a guy back when I was just out of High School. He built a big block chevy with 13:1 pistons and a blower. When he started it up, he reved it once, and pieces went flying. A friend of mine at the time told him what would happen, and it did!

 

You can put a turbo on a IDI and run it with stock compression and it makes the motor run right. A IDI without a turbo sucks more gas and has no power from what I am told. The catch is you can not run a lot of boost.


The 93 94 IDI with turbo is how they should have come from the Ford factory in the 80's.

 

but the world wasn't ready yet.the diesel option over the gas was already quite a bit more.people wouldn't yet pay more yet again for a turbo diesel.it took years of the idi to pave the road to show consumers that not only was the diesel option worth the added expense over gas,but so was a turbocharged one.thus now the idi had done it's job and set up the diesel engines thereafter for huge success.

fast forward to today and now with the power wars getting out of hand to bring to market unnecessary power levels,increased advanced electronic controls,increased emission standards and the pricing of the modern diesel trucks are pricing themselves out of the market for the average working man.now if you want to buy a diesel truck,you should have a devoted 20k set aside for if the "water" hits the fan fund,locked and loaded and be paying for extended warranty coverage to cover what it will.all of which require you to basically go to work for ford part time just to pay off the truck and then hope to god nothing happens to it,or you'll need a old backup truck to work with while yours is in the shop because odds are,you wont be able to work on one yourself.
thats always been the way with man though,if a little is good,then surely a lot must be better lol.i guess they wont stop until they break the market and find the threshold.at 40-50k i would have figured that would have done it,but Americans are some darn big spenders.who knows how far it will go.

doesn't matter much to me as i was priced out before the power wars even began lol.
i do know the price of the new trucks effect us all.i had to call up my insurance co, and make sure i was covered in the event i am ever in an accident with a modern diesel truck.what if your at fault and don't have enough coverage to cover a 60-75k king ranch? (getting close to what some pay for their homes for god shake) that could be enough to destroy many small businesses.

 

Yaa for a small truck they do want a lot and they are not very practical to keep long term.

 

FordF250HDXLT, could not have said it better. Man even if I had the money, these new Diesels are just insanely priced......really when will it end. I'm glad I've got mine and I hope to keep it a long while yet. Hey... look, a Patriot and a Jet fan agree on something ! God I love this site !

 

Service industries here like towing companies are going all gas now. Just can't afford the diesels and the continued required maintenance and constant emissions repairs.

The last diesel UPS delivery truck was running around here 5 or 6 years ago. They are all gas now because it's just cheaper.
FedEx still runs 7.3 trucks here, they have died in my driveway more than a few times!
