Oil pan gasket replacement

I�ve been meaning to put this together for a while to help others with their oil pan gasket replacement. First I apologize if I leave out some info but I did this last month and it's no longer fresh in my mind. Really I wanted to post pics because that's what I was missing when I was researching this job. Before getting started I drained the oil, removed the engine cover, supported the car on jack stands, removed the splash guards from engine and transmission, removed the belt from the power steering pump, and removed the front wheels. In order to support the motor I bought an engine support bar from HF. Use your tow hook and screw it in the hole under your engine cover. Can�t really use the chain but the support will hook up to the tow hook and hold the weight fine. I wrapped the chain around it just in case but it�s not needed.

Next up I started unbolting everything starting with the strut bolts up top. Then the cross frame support since it blocks some of the bolts for the sub frame and engine mounts. I bought an E socket and bit set which will be needed for the power steering rack, engine mounts, and oil pan bolts.

Once the sub frame bolts were removed and steering rack pushed out of the way I lowered it slowly for clearance since I still needed to remove the lower radiator hose that is attached to the sub frame by two torx screws.

With the sub frame out of the way I moved on to the oil pan. If you have an auto there are two transmission lines that are bolted to the oil pan in two locations. One in the front and the other is on the driver side of the pan which was a pain for me to get to.

Next up is unbolting the power steering pump from the oil pan which is straight forward so I didn�t take pics. Now all that�s left is the oil pan bolts which are not that tight but the ones on the driver side will require an extension and u-joint. You have to work the pan around to oil tube that�s extends into the pan but the removal isn�t bad as long as you have enough room between the pan and sub frame. Once out I cleaned the matting surface of both the pan and the block with brake cleaner and scraped away any pieces of the old gasket left behind.

I applied gasket sealer to the front and rear of the new gasket on both side and installed on the oil pan. Installing the pan back in was a two man job since I was on my back under the car. There was no way I could have maneuver the pan into position without help from friends. Installing the new bolts was also a pain since you have to do a cross pattern and I couldn�t find the exact torque specs but I�ve been driving for a month now and no leaks. Hope this is helpful to others that will take on this task.
