Gas leaking from the hole under water pump!?

[evil_stroke]

well that and there is more pressure in the water pump housing so the water is gonna be pushed inside the crank case...

Okay, I have done some thinking and I think I finally have the solution to this problem. Since coolant would leak INTO the crankcase, and fuel really COULDN'T leak into the water pump (because it would have to almost fill the case for that to happen) Your mechanical seal on the water pump must be bad, that is usually why anything comes out of the weep hole and.............. YOU MUST HAVE FILLED YOUR RADIATOR WITH GAS INSTEAD OF COOLANT!!! Pop the rad cap off and give it a wiff???

I am so smart :]:]:]:]:]

honestly though what else could it be lol

It's breaking the laws of physics!




There are 2 seals on the w.p. shaft with a void in the middle, the mechanical seal on the w.p. side and an oil seal on the case side. IIRC there was an internal weep hole in that void, which then led into another cavity in the case, then that cavity had a weep hole that exited out the bottom of the case. I'll take pics when I take it apart today.

so what went bad?? the oil seal?

[quadzilla87]

put a screw in the hole
no water or gas will leak then

Well, looks like the pto crank seal and the water pump oil seal are bad. The gas went past the bad needle and seat, through a crank seal, then through the w.p. oil seal and out the weep hole. (just like the mouse trap game )







Took off the w.p. cover and every thing looked alright, but then I took out the oil check bolt and a half gallon of gas comes pouring out. And that was all that came out, damn thing must have been almost out of oil. Probably burned off from the bad crank seal. The previous owner had only put a couple hours run time on this engine since he fully rebuilt it, never rode it enough to find all the bugs, guess it's time to go back and fix his mistakes...

wow all i got to say is good luck man
ive never seen that b4 lol

You might drain the oil and smell it see if has gas in it. I know when i get a diesel in the shop that may have gas in the fuel I put it in starfoam cup if it disolves there is gas in it. I think the oil is heavier than gas and the gas may sit on top. But if it draining into the crank case, it have to go past the rings in the cylinder. SO Drain that case asap not sure how good gas is on the crank seals.

Wow I wouldnt have bet money on it! Kind of like a 2006 F150 4wd I had this week. The guy had been losing transmission fluid out his automatic. I could find no leaks it was dry as heck. So when I checked the transfercase level about 7 quarts drained out (it only holds 2qts). Had to put a new seal on the transfercase and in week or 2 I will know if its fixed.

Hope your clutches arent ruint to. I cleaned mine off with solvent or the fact they laid in box for 3yrs and they slipped like something terrible. I would definetly hunt up some clutches, wp seals, crank seals.
