So I got my Bosch OEM O2 sensor from Arizona Autohaus yesterday (incredibly $96 for the front sensor)...I popped it in there (neglecting the huge exhaust leak after the cat) and looked towards the front of the car where I saw a ton of oil all over the bottom of the block. I just changed the oil/filter and there was oil there then too. I thought it was the dip-stick o-ring so I replaced that and made sure the dipstick was firmly in the pan. The oil looks like its starting from below the oil filter. I checked it and its tight (couldn't not tighten it anymore by hand). But there was also oil on the two lines in front of the filter (I'm guessing those are the oil cooler lines). Are those known to fail and cause leaks?

AT least the RMS isn't leaking...yet...
Steering Rack is leaking flud like its job
Trans is leaking fluid like its job (or maybe thats the oil but I doubt it)

stupid car...

But yeah, search Google for Arizona Autohaus and then do a search for your car and they have the Bosch OEM O2 sensors for $96...not a bad deal, and hopefully I don't get anymore codes

Curious about the oil cooler lines also.

also, if anybody has replaced these, are they hard to do?

Ive done it and its not the hardest thing in the world, but not the easiest either. You need hands like a smurf. Be sure to get all new gaskets for everything also, not just the lines. PM me if you have any questions, it took me about 3hrs but it was my first time, I am positive I could do it faster now.

well do you have to remove the intake manifold? or can you get to it without doring that? how much did the parts cost you?

I'm still wondering if it could be leaking from the oil filter...is there a gasket up there? (besides the oil filter ring)...

Maybe you want to check if your filter is properly seated.

Raise the car, ramps or whatever, open the filler cap, then unscrew the oil filter and take it off. You'll lose maybe a quart of oil, whatever is in the filter, but the majority of all that fresh oil you just put in will be sitting in the oil pan undisturbed.

Then wipe everything clean, do a visual inspection. Make sure the little ring/gasket is in good shape and seats properly when you replace the filter. See if that stops the leak.

I had oil leak once like yours and low and behold the old "O" ring was still up in there...came off the old filter...so there were 2...the old one and the new one that was still attached to the oil filter and they were not mating well...so therefore the leak. Worth a check, but you'll have to drain your oil to check this.

my money is on crossed threads on the oil filter! Got a set of feeler gauges?

like I said above - no need to drain the oil to check this. Just unscrew the oil filter, some oil will spill out like in a usual oil change, but the rest of the oil will stay down in the pan.

Ooooops, you're right...must have had a brain fart.

definitely not cross threaded....goes in there real easy...

thanks guys, don't know when I can pull the oil filter again, but I'll try to get to it soon...

No need to take off the intake manifold, I did it with a set of rhino ramps and some sockets. One of the hardest things was getting one of the line clamps threaded back near the oil filter. You need the two oil cooler lines, new o rings, and be sure to replace the compression circlips that hold the lines to the radiator. I actually had one of my lines pop off right after I did it on the hwy, I reused the clips, to this day I still find pockets of oil in random places. In total it cost me about 300, but I went through the stealership on a weekend. If you plan I imagine FCP could get the stuff cheaper.
