I thought this might be a god idea for a topic. What are the some of the biggest engineering gaffes you have come across and for extra credit tell us why or how it might of happened! Please feel free to bash any and all car manufacturers!

I'll go first! Ford using 2 piece sparkplugs in a few of their engines! I have no logical reason why they would do that!

hmmmm ... international's 6.0 powerstroke egr & oil coolers coupled with the super-sensitive heiu injectors & low grade head bolts!

1) sand cast internals clog oil cooler (or fails on its own lol). it fails & leaks oil into coolant. contaminated coolant clogs egr cooler (or it fails on its own lolol). cooler fails & leaks. sooner or later stretch headbolts & blow HGs or crack head.

2) Any contamination of oil (sandcasting, coolant, etc in oil...) will cause the hydo-electric injectors to fail (aka stiction).

3) bad injectors may cause egr passages to clog early & possibly cuase fault in egr cooler...

4) another note on the injectors: they were designed before ULS diesel was mandated. makes stiction happen much more often unless lube additaves are put in the tank

its a big circular mess lol!

the 6.4 had similar problems even though they had the first round of piezo injectors. pretty sure that's why ford ditched international & went in house for the 6.7.

edit: i know i'm off on some of the terminology... still learning the world of powerstroke

The 3.0 ranger. (Just kidding!)

I've yet to embrace the smart key technology...I rented an Altima and figured out the push button starter but could not figure out how to shut it down...parked near a noisy fan, locked it and went to lunch. I could not hear the motor but figured once i walked away it would default and shut down...but came back and it was running the whole time with air on lol. I'm sure that's been changed by now.

Helped do a resto on a 60s xke and the starter had bolts accessed thru the glove box iirc.
I was there for my assortment of strange offset whitworth wrenches.

Are you referring to two sparkplugs per cylinder, modelageek?

no the 5.4 3V used 2 piece plugs

Well we must admit that designing an oil pump system that allows the engine to keep running while the pump is failing was not one of Fords "Brighter Ideas"!

----------

No, that did not bother me much. I was referring to Fords 4.6 and 5.4 engines. They used sparkplugs that were 2 pieces. They would snap while removing them. Ford would charge $800 to change them

Edit: my bad it was the 5.4 and 6.8

Fords 4.0 SOHC.. the timing chains why not just em both in the front

all the needs to be done is spend $40 on an inline coolant filter and a lot of the problems go away. If you were todo an egr delete on any diesel it will run better, longer, and get better mileage. Head studs are about the worst thing on these truck and they are fine as long as you keep the truck stock. And ford stoped with the 6.4 because it was getting the worst mileage out of any of its competition by several gallons. But if you did the right stuff the were the best one out there as long as you didn't care about the mileage you were getting

chevy running the ABS through the FUCKING radio!

1. doing the right stuff as in bypassing/upgrading/ deleting said design flaws.

2. coolant filter helps tremendously! but $40 just for the filter housing maybe. all together maybe $80 with fittings & filter.

3. the stock head bolts, HGs ,& heads are no match to a failed egr cooler in any way shape or form. same for the injectors & turbo run with contaminated oil

4. the reason why they ditched international has got to be more complicated lol

edit: Ray, i'm not trying to be a jerkoff, just clarifying

lol yeah i feel better

but i didn't even get into the gasser egr systems lol

the words Chevy and wiring are just cluster fucks in them selves. I watched my dad do the radio swap in my moms vette biggest damn cluster of bs I've ever seen. Every thing is ran through the radio in those cars and I do mean everything. He had to have crutch field send him at least 5 different conversion harnesses and 3 modules for the factory amp, onstar, and the Sirius radio. Took him a hole weekend to do that install and it was a pita
