Car Forum / Dodge / Dodge Trucks / April 2006gas pump leak?
I checked out the engine oil in the 360 that came with the 72 W100 (with snow plow and harness) and although the oil had no grit, it did smell of gasoline. The engine is not seized. Other than giving it an oil change before doing anything else, can I assume it could be a gas pump leak, and I ought to change that too before trying to turn it over, or, could I just try to start it after the oil change, and see if it runs at all, check the oil again for gasoline after running it for a few minutes? (How much damage a short term test might do if it leaks gasoline again) -- or, am I likely to do no damage because the engine is already screwed? Oh, also, I am pretty sure the 360 and 400 have a compatible tranny -- the 720? In which case I could swap in this tranny to the 400 -- both are automatic 4x4's? The tranny oil looks good -- esp. since this truck has sat for at least a few years. would like to try to get the 360 moving (even with portable gas container method) to see if tranny will move from 1st to 2nd smoothly around the yard). If 360 is good, tranny on 400 might eventually be destined for it after rebuild.

There are a couple ways for gas and oil to mix; leaky fuel pump, leaky / flooding carb. Replace the pump and the oil before starting. Gas is a lousy engine lubricant. > Oh, also, I am pretty sure the 360 and 400 have a compatible tranny -- > the 720?

Sorry, Rach, but it's a no-go. The 360 and then 400 have different bellhousing bolt patterns, and, iirc, different engine balancing ( 360 = external balanced, 400 = internal balanced) so the torque coinverter would need to be changed. To help identify the differences, the 273-360 engines have the distributor in the back ( LA blocks) and the 400 has it up front (B / RB blocks) > would like to try to get the 360 moving (even with portable gas container > method) to see if tranny will move from 1st to 2nd smoothly around the [quoted text clipped - 3 lines] > Thanks, > rach I wish they would swap for you because I know you need to stretch the dollars, but I'm afraid they won't.

What's wrong with the 400? absolutely nothing -- but before Richard died he told me the transmission needs about $300 in parts -- plus labour > Budd thanks for your help, rach >>> I checked out the engine oil in the 360 that came with the 72 W100 (with >>> snow plow and harness) and although the oil had no grit, it did smell of [quoted text clipped - 12 lines] > > ok will do It's cheaper , as well as better, in this case, to be safe than sorry. >>> Oh, also, I am pretty sure the 360 and 400 have a compatible tranny -- >>> the 720?

The bolt patterns are too far different in bolt locations as well as physical diameter. The only options that would allow the swapwould add from a few hundred dollars to possibly a thousand dollars to the cost. >> To help identify the differences, the 273-360 engines have the >> distributor in the back ( LA blocks) and the 400 has it up front (B / RB [quoted text clipped - 12 lines] > absolutely nothing -- but before Richard died he told me the transmission > needs about $300 in parts -- plus labour Did he say what it was doing? or not doing? We've several good trans guys here in the group and it could be simple. All the differences between small block and big block transmissions are in the way the case is made. Internal parts will swap as long as both are 727 transmissions and you swap all the parts ( there are minor differences from year to year). >> Budd > > thanks for your help, > rach You're always welcome, my friend.

So many 727/904 problems can be repaired with a fluid / filter change and band adjustments. > We've several good trans guys >> here in the group [quoted text clipped - 16 lines] > and if it's simple, you know I am going to want to get my grubby little > hands in there <grn> <LOL> One of these days ya gotta send me a pic of you and Claude so I can put faces to all this "can-do" attitude running amuck in the Canadian woods. > All the differences between small >> block and big block transmissions are in the way the case is made.

That number is just a casting number, probably. Look at the shape of the pan. if the pan has a semi-circular protrusion where the dipstick enters the case, then you have a 727, if not, it's probably a 904. You need to verify the spline counts and diameters on torque converters / input shafts before swapping parts. There were a couple years where those were changed just enough to cause problems. >>>> Budd >>> thanks for your help, [quoted text clipped - 3 lines] > > thank you. i really appreciate that Aw, shuckins, ma'am, tweren't nuttin.

I would imagine he gasoline just evaporates but to be safe chenge the oil also. Bob AZ > Rach > [quoted text clipped - 3 lines] > > Bob AZ thanks Bob, will do -- oil is cheap and easy to change, but these motors are not <grn> -- it's the fuel pump i was more hoping to avoid until the test was done -- need a flexible extension i think -- the pump was a total pita to change in the 225 (1/32 turns at a time for the underside bolts) maybe i'll look into hooking up the electric fuel pump until the engine has been tested rach |
