It’s fair to say the car hasn’t been the cheapest thing to run, where thoughts of selling up were dancing in the horizons of my mind. They often do when faced with expenditure. Why? I wished to change the big-end bearings.
But why? That is pretty simple really. The way I see it, two things can finish off an M3, well, make keeping the car unviable:
1) A boot floor cracked badly enough to warrant a new Rear Axle Carrier Panel (RACP); About £5k no matter where you go
2) The Rod Bearings; If these go and the crank is marked/scored there is a question mark over whether the crankshaft can be saved; They are tuftrided from the factory and it is said generally reground cranks aren’t as strong as original items. A shame as a new crank is over £2k from BMW, and even the S54 engines are £3k secondhand! That is before fitting!
Yes, head gaskets, VANOS & SMG pumps can go, but generally, the expense is much smaller and easier to spot without generally writing the car off. In those cases, cheaper and potentially longer lasting solutions have been found too in the case of the VANOS & SMG gubbins.
With that in mind I dropped the car off to Autobahn in Halesowen.
Given that Rob was known to colleagues of mine in addition to him racing E46 M3s I figured the car would be in safe hands.
All was going well! I dropped the car off on a Saturday, and then went to the Restoration show at the NEC. That was until Tuesday. I had a phonecall to say that one of my rod bearing bolts was being stubborn.
It was fair to say that I was slightly anxious at this point! But how would it all go? Would this really be a big stalling point?
From where I last was with the the old girl it was fair to say that it was busy redeeming itself. For the next 3 months it was nice where the car had been spend free for once. It was 3 months in come August when I would broke this rule. Why? I needed cupholders and an SMG relay. While the relay could be justified what about the former item? This was easy ; I was going to drive the M3 down to Spain for a bit of a trip.
Given their reputation these days for many things going wrong I was apprehensive about doing so. Thoughts about the head gasket, SMG pump, VANOS and bottom end issues all went through my head. I had taken £200 shitters previously across Europe so why worry so much about this trip? I guess when it is your pride and joy that has cost you a few quid to maintain this feeling is quite normal.
Since the car had a service during the oil cooler saga only months before I left I knew it would be a case of checking the car over. Before I knew it there was little else to do but fit the new cupholders. While there was a mixup with the colour of the cupholders being delivered to me Cotswold BMW to their credit bent over backwards to get me out of this jam.
The correct items in place. The colours actually OK despite the photos showing otherwise
I did not hesitate to fit the grey cupholders and to pack my tools and spares for the trip. Little did I know the time for me to leave the UK for Spain would creep up very quickly! But at least the car was a joy to drive down, with me having some great company in the form of a good friend for the trip. Leaving at 6pm on a Thursday night however would hamper how much progress we made in France that day, especially when the Eurotunnel had a delay on of an hour until we actually would get onto the boat. With that in mind we made ourselves comfortable and attempted to sleep on the train and while waiting for the train with limited success.
Once in France and the time now being past 12AM we decided to call it a night and stopped off just outside Calais to rest and hit the road the next day.
This day would be testing. We would be driving from Boulogne-Sur-Mer to Pamplona, Spain. In a day. Yup, it was not going to be a short hop. With that in mind we jumped into the car and hit the autoroute. The M3 did come into its own here
Despite it being 14 years old and with a few miles on the clock it literally cruised all of the way down through France. 4 hours felt more like 2 and even the weather was cheering up for us. This would all change when he hit Bordeaux at 4pm that day. Going through the hot traffic you could hear the car’s fan operating at maximum speed as the heat went up to 33 degrees centigrade. The car by this point had been running for 7 hours with us only stopping for lunch and fuel. Before 5PM with the car crawling around Bordeaux a few warning lights came on! It was running cool (albeit the oil temps going to over 100 degrees centigrade) and generally fine however. With this in mind I decided to stop off and let the car cool off for ½ an hour and let the traffic die down. Oh, and treat myself to an ice cream.
You have to love the French motorways. Quick and stress free driving!
The M3 certainly was a great companion in France
With that done it was then time to hit the road again with our next stop being Pamplona. After Bordeaux however this leg would drag on a little. However, we made it to Pamplona for 9:30 to meet up with our friend who had been there for quite some time. Not a bad time to get there really!
After having a beer and a small meal we all knew it was time to get to bed and to see what sights Pamplona had to offer. The truth is it was more than I was expecting!
