I did actually see this previously when I was searching through the forum..... Looks like your within 15% with those results
Great to see your R over the 100K mark. How long have you had it?
Have you carried out walnut blasting on the R? Needed to change the seals? Any maintenance recommendations?
I had the R over the course of over 5 years and used it almost daily. Mostly for long hauls all around Europe and the country.
No, I did no walnut blasting on mine as it was not required. As I hardly ever used it for short trips or city driving there was no build up on the intake. But for the peace of mind I once did an italian tune up. And then weeks after that the intake was partially stripped down for taking pictures of intake's inside. There was only a minor amount of build up so we decided to not strip it down any further and not to clean it. It was all OK.
Over the years I also learnt that a rainy/drizzly day and a long autobahn drive at high speeds help to clean up the residue in the intake due to high air humidity. The engine always felt like new afterwards.
There were no other work on the engine required over the course of my ownership, except for those I listed in my thread. No valve seat gaskets. They were fine. I drove the car all the time so they had no chance to harden and go bad.
For maintenance I strongly recommend to change the engine oil more regularly than advised. If hard driven then cut the oil change schedule by half. And keep that oil level ALWAYS at max. If it drops by 3mm at the stick, fill it up. And do not use any racing oil, like 10w60. Just stick to what Pug recommends. And while talking about oil, don't forget to change the gearbox oil from time to time. It often get overlooked in the process but is as essential as the engine oil.
