I recently had a small oil leak that was pooling in the V of the engine. Since I just bought the car a few weeks ago I tend to inspect the car after every drive to see if everything looks as it should and notice a small pool of oil in the V of the engine. Before I purchased the car I knew it just had an oil change, so I assumed that it was probably when they changed the oil from a possible sloppy job on the filter removal. However, when I was cleaning it up with paper towels and then q-tips tapped to the end of shish kabob sticks (Lamborghini approved tool for the job) I noticed that there was small traces of oil way further along the back of the block then if it was just a sloppy oil filter change. I cleaned it all up the best I could and took the car for a quick drive. To no surprise at this point there were more small traces of oil pooling in the V of the engine. I searched all over and found a bunch of posts describing this happening to other owners, but couldn't find a good tutorial on how to get to it. At this point I went on the popular online lambo parts seller with the diagrams and found the various gaskets that would be needed. Based on where my oil was leaking I know it was coming from the main oil filter body housing gasket (part #07L103161D). However, after reading more about this common issue I thought it would be good practice from member suggestions to replace the oil pipe gasket (part #07L115359) along with the other common leaking source of the o-ring at the end of the pipe that connects it to the block (part #N91104101) as a preventive measure. Once I had the part numbers I went over to Lamborghini Dallas and got with Andrew Smith in the parts area. Andrew was really helpful, so if you're in the area pay them a visit.
Since I couldn't find a good guide online and have never taken apart a Lamborghini before I did significantly more than I needed to, so please learn from my mistakes... The job is not as bad as I made it for myself. I'll put my logic when disassembling as well below. Also, if you decide to take this on as with any automotive repair good organization of the parts that you pull off will pay their dividends later if you take the time to bag and label them.
Before you start I recommend getting 3-4 large bath towels or moving blankets from the house so that you can place one on each side of the rear quarter panel and then the rear bumper. I made sure the car was clean and free of debris prior to putting the towels down to avoid unwanted scratches.
Here is a photo of the leak that I was experiencing. This was apparent all the way back through the block and could also be seen from the gaps between the intake manifold piping down to the block.

Step 1) Remove the airbox hoses that connect to the throttle body. These are connected by (2) hose clamps on each tube. Just loosen the clamps and pull the hose free from the throttle body. I went ahead and took off the entire airbox upper assembly to make pulling them off easier, but this isn't needed.

Step 2) Remove the throttle bodies. These are connected to the intake manifold by 4 large hex bolts. Use an allen wrench to break the bolts free. Before loosening the bolts entirely or removing them disconnect the connectors connected to each throttle body. Take caution when removing them that there is a gasket between them and the intake manifold. You'll want to be careful to not bend them so you can reuse them. I set each throttle body aside on my work bench and put the long bolts back in them so I would know where everything was when it came time to reassemble. Also, the throttle bodies are both the exact same to my knowledge, but I went ahead and marked with blue tape which side was which just to be safe.

Now this next step is where I feel a bit dumb and hope that maybe, just maybe, my learning curve will be able to help someone else... I searched high and low to research before removing anything. I searched on how to remove the intake manifold so I could freely work on the gaskets for the oil filter housing. I won't be receiving any awards for my googling skills after this, because I could not find any answers to how to remove the intake manifold on our early gallardos besides everyone saying it's easy. In my genius brain I thought I needed to remove the top half of the intake manifold to remove the lower portion. I'm here to share the good news to anyone who isn't aware that it isn't the case and will save you an hour if not two (such as in my case) if it's your first time doing this. Normally this wouldn't be a big deal, but let me tell you what a pain in the a$$ it was to get a star bit into the tiny crevices where the bolts live. Also, half of them are from the bottom side and it's almost impossible to not drop a bolt. Enjoy the next few photos of our beautiful engine, but this part was not needed and I will call these bonus learning photos. I won't post steps to this since it wasn't needed, but if anyone was having trouble removing this for other reasons, like powder coating it, just let me know and I'm happy to help.

Step 3) Remove all hoses. There are quite a few lines that are connected to the intake manifold. Removing them is pretty simple. I took pictures to ensure that I put them back correctly, but to be honest it wasn't that bad. To remove the first few you will need a pair of pliers (ones without teeth would be preferred here to not mar the clamps) to slide the clamps down. Simply squeeze them and slide them down a few inches and then just gently pull off the hoses. These may seem stuck at first, but just keep pulling straight out with force building to not break or bend the metal parts they connect to with the manifold. These aren't cheap or easily available.
