Will it be as reliable as my 113.00 motor?
I would like to know - if I replace the head bolts and lifters in my 2008 E63 will my 156.00 6.3L motor be as reliable as my 113.00 5.5L?

You have a 6.3L E63? What'd yo do to get that extra 0.1 of displacement?
I hate to break it to you, but your E55 is a 5.4L.

How about 6,208cc and 5439cc - Thanks, now that we have that cleared up - how about your opinions or knowledge about doing the head bolt repair on the M156 - can the M156 motor be as durable as the M113 motor after the head bolt repair? Or is the M156 just a weaker design, because of the increased power and complexity even after the head bolt repair. Can the M156 be a daily driver, if scheduled maintenance is completed and last 200,000 miles like the M113?

Lots of people daily drive the E63, me included. I have just over 100K miles, the last 13K are mine. Couple oil leaks, an air intake leak that was present when I bought the car, and routine maintenance. Really a wonderful ride combination of power and refinement. Never owned anything else quite like it.

I think you can certainly daily drive the M156 and I have been doing so for past couple years. The only engine related issue I have had thus far is a very slow oil leak (knock on wood) and i just rolled over 100K. Seems like this motor has a really bad rep regarding reliability from that d*** head bolt issue that is blown out of proportion..

Can't say much, since I don't have any first-hand experience with the M156 motor. But I'd definitely keep your 2002 E55. Great car. Even with 150K miles, it's got a lot of miles left in it! I like the 2002 E55 more in some ways than the W211 E55s, which I find the ride too stiff. Steering rack is mostly uncommunicative on both models. But I do like the E55's suspension much more.
Can you find a nice W211 E55 that meets your requirements? Although, please test drive the W211 E55 and compare with a W211 E63, I find the E63's brakes and steering are notably improved; brake pedal feel is much more communicative in the E63, and the steering is more communicative as well. The 7 speed transmission also is more problematic than the 5 speed units on the W210 and W211 E55s.

Honestly the 6.3 has a few issues like you said but it depends on maintenance and your luck. The headbolt thing you can do and it won't destroy the bank. The camshafts though, if they're worn then they're not cheap. Not the best engine reliability wise. Maybe the problems are blown out of proportions but they are there no doubt. I suppose if you put ARP head studs and new lifters and cams it'll be reliable for a long time. Oil changes are very important on these engines. I change my oil every 2500 miles. It may be expensive but the way I drive it and the high performance nature of the engine warrants it. Every 12,000 miles is a JOKE on an engine like this.
