    Ok, my truck is leaking a bit more oil than I would like it to(puddles where ever i park it.) When I check my oil, it reads like it has a quart extra in it(past the full line.) My oil pressure has gone down some too, more when im idling that when im going. Now, i know my dipstick is wrong, because it leak so much and i havent put any oil in it for a few weeks now. So what would cause the level in the pan to be high but the pressure to be low? Could it be a leak in the system? Im also not sure where the leak is coming from. I need to get some degreaser and then drive and see whats oily after. Any Ideas? /forums/images/icons/confused.gif

    Could be your fuel pump bellows has a hole and pumping fuel into you oil pan causing your oil level to raise. This will also thin out your oil causing leaks.

    The oil looks like it hasnt been contaminated by fuel or coolant

    Drain it down to the proper level and see if it repeats.

    Looks can be deceiving. Smell the dipstick. Old Chevy Caprice I had exhibited the same problem, choke was malfunctioning, and I was get gas in the oil. Was real obvious when I smelled the dipstick, and I could smell fuel. Hope this helps.

    You better find out if it is fuel or water; water will make the oil lighter or milky in color; fuel on the other hand will give make the oil smell like fuel and could eventuly lead to an explosion in the crankcase.

    well, i drained the oil and refilled it. Ill see in a few days if it rises past the full level. I tried smelling the oil and i think i smelled gas, but im not sure, havent really taken the time before to smell the dipstick. If it is the fuel pump, do i just need to replace it? Ive changed em before so it wont be any trouble.
