Andrew?
It was making a little rattling/ticking noise but hopefully it is the oil pump chain that is slapping around in there.

Yes. Andrew. I know he has one. Andrew is just his username. Most people know him by the name Andrew. If it is of any comfort. I had an oil pump fail on a vw once while i was on the freeway. Heard the bearings clicking and clacking , limped it another 3 miles home and it ran fine after replacing the oil pump

You can just make an engine support from 2 2x6s, an eye bolt, and a couple rags to protect the paint on the strut towers. Easy as pie!

Just to see what the damage is.
I have all of the bolts off of the oil pan. It still is really tight on the transmission side even with loosening the two lower trans bolts. Do I need to pull the trans to get the pan off?? Help!!
The front of the pan is loose and while I was hitting it with a rubber mallet you can definitely hear something metal bouncing around in there. I think it is the oil pump sprocket by the sound of it.

Trans inspection cover gets removed to get the last few screws out. Hope the results come back okay
Is that the sheet metal piece that can only be removed by removing the trans?

Nope its the bottom half of the bellhousing, cast aluminum piece. Held on with a few inverted torx bolts
I don't have an access panel on the trans. I'm going to loosen the trans a lot more and see what happens.

Snap is thinking the bowl reinforcment that the 12v engines have. 24v doesn't have this. You should not have to loosen the transmission. Are you sure it is not just RTV "gluing" it on?
I'll give it another good prying. I was getting nervous about breaking it before.

As long as you got all of the bolts out it should come off, use a putty knife to work it off of there. I'm sure you did, but double check the perimeter for any bolts that you could have missed. There are a couple at the back that are long if I remember right that go into the rear main seal housing but they are the same diameter as all of the rest. If you still have trouble I have a spare oil pan that I could take a pic of.

I just found my motivation. Just raced a Viper on the freeway in the M3. Needless to say I need a turbo in my life at all times. Sunday is go time.

Finally! As I suspected but a little worse. Must have had loosened up and was turning it at weird angle so it sheared off. #powerproblems #havearaceshopbuilditnexttime
What was in the bottom of the pan.

I think this is the best option.

Glad you got the pan off. The chain driving the oil pump is a different one from the cams, right? Any oil analysis results yet
There are two different chains. One guy on R3V said that the tensioner would have been affected but the tensioner only touches the timing chain not the oil pump chain. I'm confused about that.
No results yet since I haven't mailed it. The sample I took won't be 100% accurate because, as you know, you need to heat up the oil and mix it up. I took the sample when the oil was about half way done draining. I will be monitoring the oil closely from here on out just so I know when to replace my bearings.
