For a while now I've been leaking a little bit of oil. Its usually not enough for force me to refill between oil changes, but it certainly is missing some. I just changed my oil 2 weeks ago, and realized the rubber o-ring in the pan bolt was cracked. I also noticed a tiny amount of oil on the oil filter. So I get a new drain bolt gasket, and cleaned the filter mating surface on the block with a paper towel. Now its leaking significantly more, and it seems to be coming from around the filter. There appears to be a little bit of oil all around the filter gasket, and the oil seems to be dripping from around the bottom of the filter. Just today I was missing almost 3/4 of a qt of oil. I've read the pan gasket is often at fault. How do I check this? Also, I can remove the filter with out losing a lot of oil right? I've never removed the filter without draining the pan first. Codes P0401 and P0402 just appeared a few weeks or two ago. Could that cause pressurizing problems in the crankcase?

I also got my oil test report back from Blackstone: http://i.imgur.com/zb3Wu.png Looks like I might have a head gasket problem. I've had problems with losing coolant, but I've been chalking it up to a ****** after market overflow tank with a cap that doesn't quite seal any more.

Looks like my Bull is finally starting to cause some headaches after 6 years.

Be sure that when you remove the old filter that the old gasket comes off with it.
If the old gasket is left on the block with the new gasket/filter placed on top of it, it will definately leak!! :)

Do you have the tec or vulcan engine??

Yeah, I lubed the gasket. I turned it maybe 1/2 turn past contact.
Directions are 3/4th turn past good contact.

You are light on that one.

Suggestion.

I maintain 3 cars so I change one about each month. I keep a paint pen with my funnel which I keep wrapped in a paper towel and in a ziplock bag. Clean if good. I take the paint pen and put an arrow on the end of my "Motorcraft" filter. When installing, I note which way the arrow points when good contact is made. 3/4th turn more, always. Never had an issue with leaks.

BUT watch out for old gasket sticking to the engine! In fact, last one I changed, I had already wiped the surface before looking at the old filter and saw no gasket on it. Yes, there it was stuck, rather tight to the engine. I have heard first hand stories about double gasketing. Never done it, but there is always a first time. Only if my "check list memory" dies.
