The Stovebolt Site Forums The Shop Area Engine Shop 250 Oil level rising rapidly???

Just recently changed my oil and yesterday checked my dipstick and the level had doubled past the Full line. It's like a ghost has popped my hood and poured in a gallon of oil. So I drained some oil out, back to about half full and tonight, just now, my oil light came on in the cab and it's dripping a pool on the ground and it seems to be over full again.

I'm hoping I haven't blown a head gasket and have water from the radiator filling up my oil pan, I haven't noticed a different consistency in the oil and the engine runs fine. Just got rebuilt last year and only has 15,000 miles on the motor.

Any ideas? I'm out of my field on this one!

Check your fuel pump, sounds like its leaking gas in you crank case

Sounds like your fuel pump is leaking/pumping gas into the engine. Pull the dip stick and smell the oil, if it smells like gas replace the fuel pump. If it looks milky, it is water/anti freeze.

When I drained some of the oil, it was dark, but not a milky color. The radiator is topped off for the most part as well. The oil smells very heavily of gasoline however, is this the tell-tale sign?

Also, can fuel go straight from the pump into the crankcase? I know the pump is bolted onto the block but can it go through the block or something?

Yes!, the internal diaphram will pump gas right into the oil pan.

Quit driving it until you get a new fuel pump. It could very well be squirting gas on your cam thereby washing off the lubricant. It doesn't take long to ruin a cam and lifter.

Yea its parked right now, I'm having nightmares of all the scary things that could be happening inside!

put out that cigarete! drain the oil, pull the fuel pump. get a new fuel pump,fresh oil.and your good to go.

Don't even start it again "just to be sure".
Your oil viscosity is now 2, even cranking it will do more damage.

Well, I ordered the pump from American Classic, but I don't know whether to take it into the shop or try doing it myself. I don't want to drive it, but I don't want to pay to tow it, and we don't have a trailer to haul it right now.

Is removing the old one and slapping on the new one easy? I know how to seal gaskets and all that but I don't know if I have to do anything else.

To change out fuel pumps all you have to do is unbolt the old one, scrap off the old gasket to a nice clean surface. Put in the new gasket and pump. Bolt it down, reattach the fuel lines and your good to go.

Ok, so i understand there is some sort of hole in the block where it mounts up, when I unbolt it from the block will oil from my pan start pouring out of the open hole, or is it high enough that it's up past the oil level? Need to know if I should prepare my driveway for trouble or not.

the oil level is never above the top edge of the pan, somewhat below it actually - the only time you'd get oil out the pump hole is if it was running .... just don't start it with the pump off
