Is there any grease zirks on the 2008 Saturn astra?

You need to ascertain where the oil is coming from the Rocker Cover Gasket or the PCV valve?

Replace the gasket and see if it continues. It is a pain to replace the PCV according to this. You may be able to clean it with carburetor cleaner when the rocker cover is off.

Oil filter on 2008 Saturn Astra in inside of a canister that is located behind the radiator and a bit to the drivers side. A ONE-INCH socket is needed along with a ratchet, extension and universal joint to compensate for involved angle. Damage to the one-inch screw-on canister cap - I've seen a replacement available at eBay.

You can do it if you really wanted to. You'll need to make sure the steering wheel is secured and that the wheels are perfectly straight or you will wreck the front tires. You will be adding unneeded mileage onto the the car by having the front wheels turning. would be better and less costly overall to get trailer that you can put the front end up on.

the oil drain plug is on the bottom of the oil pan and the filter is on the top side of the engine toward the front. be ready for a mess!!
