oil leak blowing back on engine

I need a new air filter, but I'm thinking of just replacing the entire engine. I'd hate to cause further issues by moving a wire or air duct . With a rebuild from summit of course!!
Anyway... Kmartin, I would suggest cleaning/degreasing at least the the area around the remote oil filter and the oil pan. Then you should be able to get a better look at where things may be leaking. If oil seems to be leaking from the o rings - lucky you! Swap in a new set. More than likely the oil is leaking from the oil lines at the crimps and dripping down onto the remote filter. It isn't THAT hard to swap in a new set of lines. Then you can take your time and modify the old set to eliminate leaks as the set you just installed will leak at some point
There have also been posts about oil pan bolts becoming loose allowing leaks around the pan.
Bottom line, clean things up and look around (oh and park over cardboard��)

I would even add to that, when its parked over cardboard, start it up and let it run and get up to temp. You wont have to worry about wind blowing oil around

I have a 2003 chevy blazer 4x4. I have oil leaks for a while that is on the bottom of my oil pan. It goes up the passenger side of engine. I have notice that oil leaking at the top part of the remote oil filter, where the lines go into it. Could oil be blowing back from that spot to all over the engine?

Oh man, what a lot of responses to a post i thought that I thought I might have a hard time having people comment on it. I back after a week. This is what I did. I had cardboard under my vehicle for a while, because I really don't like oil on my new garage floor. Where most of the oil was dripping off of it(at the bottom of the oil pan), was throwing me for a loop for a while. I did a little clean up, got a look at my oil cooler lines and determined the o-ring are not the problem. I have oil droplets at most of the crimps. They appear to be relatively minor at this point. Now I did notice that at the front of the engine, that is where the bulk of the oil is coming from. Can someone explain to me, there appears to be a black casing with a wire plugged into it, the engine crank shaft comes of it and the water pump is in front of it.

That is the timing chain cover. The electrical connector is for the crankshaft position sensor. If you do end up replacing it, you will need to perform a crankshaft variation learn procedure (CASE learn).

The timing chain cover is kind of self explanatory. It has the CKP sensor in it as well as the front main seal that seals between the balancer hub and the cover.
The crankshaft variation is a value that represents the correction factor for the readings of the CKP & CMP sensor for precise reading of crankshaft position for timing & diagnostics. When you replace the cover, you will alter the correction factor so the PCM needs to learn the new correction. That is what is performed in a crankshaft variation learn or CASE learn procedure. To perform this procedure, a compatible bi-directional scan tool is required.
