Do not forget that fan bearing bracket takes an o-ring to prevent leakage. Ask me how I know.
Let us know if you need to replace the oil pan gasket too. On one of my E23 BMWs the timing chain guide rail was completely missing... it was in many parts in the oil pan.
My lower cover is leaking on the passenger side, which I suppose is to be expected at 301k. Please share any tips after you finish the job.
