So, 2012 was the year I finally got my hands on my dream car! Being a honda enthusiast this was the pinnacle of ownership, but I wanted to ensure I got the most out of the ownership experience, hence the reason I joined this forum along with a few other driving networks.
We've had many a blast on the b-roads loving how she handles, but I've always craved a European tour of some sort with like-minded folk.
So in June 2013 we snapped at the chance to join a group of 20 drivers on a euro tour to remember, traveling first through France, Luxembourg, Switzerland, Italy, to Monaco and then back, throughout this tour we'd visit the senna memorial at Monza among many other memorable places, traveling with the likes of Ferrari, Lamborghini, Bugatti Veyron etc...
As you can imagine, I had the NSX thoroughly serviced, cam-belt, new discs & pads, new tyres etc etc, to ensure I had the complete piece of mind nothing could go wrong, after all, she is a bullet proof Honda NSX!
So, on Day 4 of the tour, we left Brescia swiftly joining the motorway heading towards Monza, I felt something was wrong, I squeezed the accelerator to find there was no power, no noise, silence.... I brought the car to a gradual standstill on the hard shoulder scratching my head! Once we were towed to the local Italian garage, my heart sank, I could easily translate the words NO COMPRESSION, disaster.
Finally after weeks of waiting, it was the middle of July 2013 when our NSX arrived home, I was gutted, I knew it was some sort of engine failure, but couldn't afford to put it right ASAP, so she stayed in our garage for 5 months!
In December 2013, we took her to our specialist, who advised we were so so unlucky, it was a CRANK PULLEY FAILURE, I looked on the forums to find if anyone else had the same experience, with quite a few pictures & posts of their experiences dotted around. Science of Speed (USA) along with many other experts, advise to change this component every 10 years/100,000miles whichever the sooner. My NSX had done 71,000 miles in 21 years, and had never been touched, hindsight is a wonderful thing!
The bonding part of the Pulley had decayed over time, which catapulted into the teeth of the timing belt, causing that to seize, equalling bent valves!

On a positive, we have all the necessary parts on order, and the NSX should be back on the roads by the end of May/June, I cannot wait!
More on this story to follow..............

if you would like me to post a few pics of the Euro-tour, I'd be happy to post.

Bad enough but could have been worse I suppose. Always try to take a positive from a negative!

Got me thinking - my car is 13yrs old / 18,000miles but still with original crank pulley.
The crank pulley went on my daily driver (BMW diesel) last year - nothing worse than 150miles on the back of a breakdown truck and a £350 bill from my local garage.
What's the approx. cost / delivery time for parts for the NSX? And how involved is the replacement - could I trust the local garage mentioned above (I've used them for years to do routine repairs on all of my cars) or does it have to be Honda (I use Phoenix Honda in Linwood, still NSX specialists, but they don't get in many in these days).
The Europe trip is only 5 weeks away...

Ouch, not good. Hope the rebuild goes well...are you taking the opportunity to tweak/upgrade a few things, or keeping it stock?

Crank pulley has been mentioned on here a couple of times (know Kaz is aware of the risk - he changed mine), but it's one of those things that does bear repeating - hopefully someone else will spot this tale and get it done before they have any issues.

Thanks for the links guys.
I've just bought the pulley advertised on ebay - the part number checks out ok.
I called Phoenix Honda, who quoted £620 all-in but said the pulley is on back order and unlikely to be available before end June.

I would get it done ASAP. The job can be done without removal of the timing belt so not too bad. You need a tool to hold the crank pulley while the very tight pulley bolt is removed - your local Honda dealership should have the tool. UK price for the pulley is £483.10 if your car is MT, but I would see if you can source one from Adnan or America which should be a lot cheaper. Wouldn't think you would get charged more than 1 hour labour (have to remove the aux belts too). Part number is 13811-PR7-A02

Failing that, there is a damper pulley protection plate you can buy from the USA for about $100 which installs between the CP & TB belt cover which will stop it chewing up the TB if the CP fails. Not sure how readily available they are now though.
