100% paper filter stock. they are a little noisier when everything on the car is cold. it quiets down when it gets warmed up and the timing/fuel changes
Arek Wasyl just the sound of air rushing into the intake. it's a composite manifold and I did not have the insulating cover on, so it sounded noisy but it was actually normal.
cant say that i did... with that first worn out clutch the pedal caught very high in the stroke which was aggravating. put a new one in and it was a lot more like OEM a lot of people complain about firewall flex on these trucks, that could give you a fair amount of play
One more thing, did you re-calibrate your speedometer, or just let it go? Also when you said you had to put in a different column, did you change out the whole thing, or just remove the column shifter and install the plastic cover in it's place?
the driveshafts are the same length. there is one trick to that though because the ZF5 has larger universal joint bearings than the C6. not sure how the ZF5 size compares to the E4OD but it was nothing to change them over, 2 seconds and i was in business.
@maxhauler yeah. coming from gas into the diesel world was a little perplexing. i thought the engine was hurt the first time i ran it with the new injectors, because it sounds exactly like a spun bearing or rod knock. white smoke scares the crap out of me, especially with a diesel. hopefully yours is more bluish...
@maxhauler nope, this was after the rebuild. i put new injectors in it a few months after the rebuild was done and as it turns out, the original pump was not enough to push the new injectors. so right now im running on an in jector pump and injectors with unknown mileage. im getting married in two months so... probably at least 3 before i can get a new pump to match the new injectors.
@typedbyben That makes sense. When you get the injectors replaced, have a diesel tech set the timing on the pump. Your wallet will thank you when it comes to MPGs. Good luck.
@eatont9999 it was the pump. the new injector pop pressure was too high to be fully driven by my pump. the old ones are back in until i can afford to get a new one in there.
It sounds like a bad injector or two. Make sure you have good fuel in it and crack each injector line. The one that does not make a difference in sound (aka worse) is the one with the problem. Depending on the age of the injectors and pump, you should replace both and have them timed with the correct equipment. Replace the return lines and O-rings while you are at it (not part of your original issue, though).
@incompletehunter i get about 13-15 mpg mixed city/highway, but i cannot speak to my fuel system's state of repair... from what i understand, underdriven you can get 18 mpg out of the 7.3 unladen. seems high to me.
@LopezDR10 it wasnt bad. i was lucky enough to have just about every single part that i needed from a 5 speed truck that was getting parted out. once you get the old automatic stuff out (including the steering column), everything else is a direct swap. i didnt drill a single hole.
