ok so i put new oil in my 22r, and after a few runs the oil looks thinner and is runny, there is no antifreeze in it and the oil smells like gas....is there somthing wrong with it or is this normal...

 

Hows your compression? Might have gas washing past the rings.

 

bad fuel pump diaphram!

sometimes when a manual fuel pump goes bad, it will spew gas into the timing cover/block!

i would check that first...

 

What he said

I had my fuel pump do that. Leaking some oil out, and putting gas in. But I'm guessing there are other things that could do it.

 

I'd say the fuel pump is the easiest to check, just unbolt it. otherwise, tear into your motor to check the rings and cylinders

 

i would rather not tear into my motor....just for the fact i just drove it home dont have a shop now .....but i will check the fuel pump

 

Yeah I guess if the rings weren't sealing right you could get some gas by them, but wouldn't that also mean you're dumping gas into the cylinders? Otherwise it seems like if there was the correct amount of gas getting into the cylinders it would burn off before getting down into the oil.

I don't know enough about engines, though. Is it running fine otherwise?

 

the gas would be pushing past the rings before it gets to the spark, wherever that happens to be set, so it's probably pushing gas down into the crankcase from bottom dead center to approx. 7 degrees btdc. I wonder if it's running rich

 

ya it runs a little rich...but only till the choke comes off.....but im thinking and HOPING its the fuel pump.......because i just want to drive the stupied thing

 

ok another thing i forgot to add was....when i first hooked up all the fuel lines on my truck i had them all wrong and i was pouring some gas down the carb to try and make it run...it did for a few secs then stops, so i was maybe thinking there was fuel going places that it shouldent and somehow got into my oil?....im not sure thoe.....and is it bad to run it like that?

 

It's not good. But nothing an oil change won't fix. If you had run it a few thousand miles I'd worry more.

 

ok so i found the problem....the fuel pump was shot....i pulled it off and it was like dripping fuel...so my intsinks told me that dripping fuel was getting in the oil....and that would also be the reason my truck wont stay running at higher rpm...it will go to 5k than die...anytthing below that is fine

 

Let us know if you're right! Luckily that's an easy thing to replace. Only trick is making sure the "lobe" or whatever it's called on the cam gear is on the low side when you put the new pump in, so you don't have to compress the pump lever to get your bolts to thread. Ask me how I figured that one out.
