Never knew Garrett was a Honeywell product. Shows how uninformed I am.
As for reliable engines as SD1 questions, reminds me of the all-time clunkers. Early 80's and GM markets a diesel on a 350 gas block. Disaster.
Late 80's and Ford makes 302 gas engines with Brazilian rings and pistons. Disaster and I had one. Ford was miserable and fought me even after they admitted the problem.
2001 and GM comes out with the Duramax. I bought one. Disaster. Major breakdowns of 10 injectors. Quite a feat when the engine had only 8 cylinders. Then the Allison blew and, well, that's not an engine. GM did give me a few thousand for the trouble. That was a "drop in the bucket" but something.
Ford introduces their 6.0 diesel. Stupid son of mine bought one, it trashed, they played around and were beyond the ignorant for him so ... he buys another??? Of course it also blew up and he lost a bunch of hide along with his shirt. Ford was again the most ignorant company of all to back their products.
Now Ford has the Ecoboost. it operates on premium fuel for towing and runs a real high rpm. Runs good if you can take the noise under tow and the hideous fuel mileage. Pray you don't have turbo issues. Know of three and two are nothing but trouble. As usual Ford is miserable.
I have no clue if Chrysler/Fiat has made a bummer. Probably did. I just don't know of it. Don't even know of a single Ecodiesel with major issues, resolved or unresolved. Time will tell and some of the motors are over 20K right now.
Emissions on all the new diesels uses lots of sensors and computer controls. To me it's a time-bomb ticking. I say buy a GM gas-engine pickup or maybe a Ram with the Pentastar V6. That's a great engine with a short but good history of reliability and economy. Can't blow a turbo or fill it with water (Ford) when there is none.
GM's are uninspired pickups, a bit pricy but workmanlike with less technology and less performance/mileage.
Better yet, don't buy anything and take the bus.
