If you diy'ed it, how'd it go?
Not the OP (although I did the walnut blast on my N54 in Jan/17*), but several of my BMWs had leaky oil pans (M20, M30, S38) but it was just loose bolts, and I mean finger tight they were that loose. Snugged them back up and the leaks stopped. Not to say that's the case on an N54 though, but I'd give it a check before tearing it all apart.

* I had the cruddiest intake ports I've ever seen in pictures of an N54, and my engine was running smoothly. I hadn't planned to do the blast originally, but had to pull the intake as I was doing the OFHG and there's that one bolt that you can't remove. I made the mistake of looking down into port #1...

No amount of presssure and walnuts even made a dent in the gunk, all I ended up with after the first attempt with the shells was a port jammed with walnut shells embedded in tar. I ended up using a lot of carb cleaner and some bespoke scrapers fashioned from coat hanger wire with flattened and angled ends. Scraped as much of the 'nuts and gum' out of the port, then sprayed on the carb cleaner, then again with the walnuts. I kept wondering if I'd get an explosion with the carb cleaner vapours going into the shop vac, but that never happened. My vac hoses are still coated with tar...

How not to walnut blast your intake

Wow. Have not logged on in a while and came back to this thread. Yeah. I did the oil pan gasket along with all the front suspension since it was off. I have a thread about it somewhere here.

Anyway. I have the advantage of patience and an extra car. I did it with the car on jack stands and it took me a couple weeks. Retrospectively, $1200 from the dealer does not seem to bad.

As far as walnut shells getting where they should not, itís been 25,000 miles and the car is running better than ever.

And I had to get a big compressor and sand blaster to do the job. The small stuff from harbour freight did not do anything.
