Backfires are usually out the tail pipe on deceleration and can be caused by several things. First is the most common and that is an exhaust leak close to the front of the exhaust system. Other causes are ignition timing off.
An oil leak at a breather pipe will not cause a backfire although an engine problem can cause a backfire inside the engine that can blow breather pipes off which then can be an oil leak. To be safe, you should have a compression test run on the engine to eliminate that one as a cause.


The backfire,bucking,sputtering,misfiring etc etc is most likely due to the gas still pumping into vehicle cylinder when the engine cuts out, then is overloaded with gas when the engine kicks back in.

It happens due to a rich mixture of fuel and it's bad for your plugs (ie it fouls them) and catalytic converters over time. That unburnt fuel ignites in your exhaust and you hear the backfire, sputtering.

You can also experience a popping sound due to gas flow through an exhaust. As you change gears fast gas flow is mixed with slow gas flow and a pop occurs due to the reverberations.---------

So get the compression test done, get the fuel pressure tested and this will point towards the problem.

I would assume that the timing marks when the head was put back is correct for this fix. Try to loosen up the distributor and turn it in small increments until you get the desired idling or the error clears. You may also use a timing light for accuracy. If all adjustments has been done, you may have to inspect the timing marks or the cam position sensor itself which connections may have come loose or may be bad.

Rear axle? there may be a small bolt or screw but not a wing nut. May just be corroded, hit it sharply with a large hammer, along the edge, while rotating.... be careful not to hit the lug bolt threads.....

the rear center cover must be removed to remove the axle pins. Once the cover is out you can see the houseshoe pins easily

Make sure you bleed the brakes completely, trapped air can cause the brakes to drag.

Yes, you can leave the axle housing installed, but you will have to pull the axle shafts. You will likely have to purchase a specialty tool to do this.

(If you have the massive drums found on the 3500s and some 2500's, this would also be a good time to re-grease your bearings and check your rear brake shoes and change them if worn beyond 50%, since you will have the axle ends taken apart. These drums are very heavy. Do not remove the trapped bearing from the drum.)

To go from 4:11 to 3:73, You only need to swap out the gears in the differential (including the pinion gear) Be sure to check for proper alignment and backlash. Re-install axle shafts. Replace, do not reuse any seals. You may also need to reprogram the trucks shift points for the new gear ratio to maximize efficiency results.

Note: By changing your gear ratio to 3:73 You may potentially decrease your trucks Towing/Hauling weight capacity. Many GM trucks are equipped with an Eaton mechanically locking rear (RPO code: G80). You can find out if yours is so equipped, by checking the label inside the glove box. Personally I prefer the G80.

(I have the 3:73s in My '97 C2500 and average around 10.5MPG city, but long freeway runs can hit 15+MPG. My GVW is 8600LBS, and 10,000LBS Towing capacity. "Stop & Go" driving is your worst enemy with these trucks.)

Consider if all the work involved is worth it in performance gains before going forward.

I have the same engine. I installed a banks powerpack on it and now I get about 14 on the highway and about 11 city. First thing is a tune up, plugs, wires, fuel filter, air filter, and that sorta stuff. I gutted my intake to let the engine breath better. The banks system opened up the exhaust quite a bit and it has alot more power and get better mileage. A chip can add some fuel economy as well. Any more than simple stuff like that, you'll start getting into serious money. My banks powerpack was $1800 and got me about 2mpg city and about 3 mpg highway improvement. Not much better on fuel but it did get alot more power which means I can be lighter on the gas pedal.
