'89 R3500 Crew Cab 2wd to 4wd conversion & beyond

[mrk5]

I'm have a bit of a quandary. I guess it's a bit of a cynical problem.

I've been debating whether I should replace the sensors with new ones. Like today I was looking at the MAP sensor and realizing it would be a pain in the ass to replace because it would require removing the upper plenum and the fuel rail because the bolt that holds the fuel rail down also holds the MAP sensor with the fuel rail on top. But then the cynical side of me starts wondering if sensors built today are as good as a 26 year old original even if I'm looking at GM Genuine or ACDelco sensors.

I've eyeballed that band file before.....

Trade name DYNA FILE if i recall . Super handy tool for sure .

Easy to remote mount

Leave it alone…

I have a Dynabrade Dynafile pneumatic one and I really like how handy that thing is, its also the smoothest pnuematic tool I've ever bought, I bought it not long before they came out with the M12 version. Would be nice not having the hose, and it looks like it has better clearance. But not sure they have as many options for tips as the original DynaFile

Buy GM sensors if possible, that still doesn't guarantee no problems. Sensors today are crap compared to older ones.

I agree, the amount of testing the factory sensors have to go through is crazy, used to work in that industry, there is no way the aftermarket does the same thorough testing. And usually they would put it in the contract we could not sell to anyone but them, so it is unlikely to be the OEM manufacturer if its not a GM part.

If it’s under the plenum I’d replace it. That little cavity doesn’t get any air movement so it’s a nice oven for electric components.

What's interesting is the Terminator has an onboard MAP sensor but it requires running a small vacuum line from the intake into the cab to connect it. It also has a harness connection for the factory sensor. I'm figuring the onboard MAP is there for easier install on non-standard EFI setups.

Yes and you can use the ecu for a boosted application where as if the engine is n/a it can't get a correct map reading for boost with the factory sensor.

Made my little pickup tube bracket. It's just a piece of 3/4" wide flat strap.



Torque for the oil pump bolt is no joke!

Orange filter for an orange engine?

 

[ZooMad75]

No. Throw that garbage in the can.

I don't know if those have improved over the last one that I saw cut open, which didn't have much filter media in it, but I wouldn't recommend using one myself.
I put them in the same category as Penzzoil.

 

[kgblazerfive]

get a Wix

 

[mrk5]

Haha, I got you guys! It is a new filter that I found on our shelves but I wouldn't use it. Figured it would be good for protection while painting and keep someone from using it. Now it's extra orange.

Total bottom end rebuild is complete!



Craigslist rebuild as VGG would say.

 

[sweetk30]

not even sure i would trust it for the paint job protection .

My dad swore by fram filters, idk maybe cause we were poor but the 350 that lived in my truck for 18 years was clean as a whistle

 

[mrk5]

I do remember when Fram filters were the regular recommendation.

Ironically the only filter problem I've ever had was the recent issue with the Wix filter in my wife's car.

When the Fram manufacturing was done in Corona, Ca. it was a family owned company. Sold to investors. Sent over seas for manufacturing. Went down hill fast.
