BMW Vanos rebuild service
Is your BMW down on torque? Is it guzzling petrol like a thirsty camel? Does is rattle like an old tractor in between 1.5 and 3k revs? Does the idle drop when you turn the air conditioning on?
Chances are: your Vanos unit needs a thorough overhaul.
It has been carried out on our own E34, and it was about time, too. It pulls as it should again, it has sorted out its drinking habit, made it quieter and smoother, and it is just that more enjoyable to drive, even when carrying a heavy load…We cannot emphasise enough on what a difference it makes. It is most definitely the best investment we have made on it so far. Our usual petrol station thought that we had moved because we come less often (no joke, we got to know each other pretty well).
But first, what does the Vanos do?
In a nutshell, it is a device that advances or retards the camshaft timing in order to optimise torque and fuel efficiency. These units can act either on the intake cam, or both intake and exhaust, depending on the engine model (simple or dual Vanos).
It uses engine oil pressure to operate, and under certain conditions an electrical solenoid lets engine oil in or out of the Vanos unit, permitting it to act on the camshaft. After years of use, the oil seals harden and are not effective at all anymore. The oil just seeps around them and the piston does not move accordingly, rendering it completely useless.
What are the effects of a failing Vanos?
Your Bavarian driving machine feels sluggish, develops a serious drinking problem and has become disgracefully noisy. A bit like hooligans around a football stadium, if you like. You need to develop momentum before tackling any kind of slope, throttle response is strongly delayed, the engine sometimes coughs when pulling away at the red light and you have become the laughing stock of your local car club. You have to plan well ahead when you decide to overtake, and eventually just forget about it and stay in your lane. The slow one, with the lorries and Dutch caravans.
Is it dangerous for the engine to keep on driving like this?
It does need to be taken care of at some point because if left untouched, the Vanos piston will slowly but permanently deteriorate the inside of the piston chamber. Replacement units off the shelf are scarce yet available, but they do come at a hefty price.
And that is when we come in!
We take care of the replacement of your old unit at your own home!
We come fully equipped, ready to drop our refurbished Vanos unit into your engine. After a couple of hours of careful spannering, you will be ready to storm the autobahns once again. They won’t laugh at you anymore at the club, we promise. A squeeze of the throttle gives you instant response. When you decide to overtake, just use your indicator and use that heavy foot of yours again. You are no longer afraid to park in front of your favourite hangout, and passengers may start screaming again during spirited driving. Last but not least, you will be seen at the petrol station considerably less. Yes, we were glad about that too.
If you feel up to the task of changing the Vanos unit by yourself, we can provide rebuilt units on an exhange basis. You send us your old unit, and we send you back a fully refurbished one. It is an even more economic solution, but your pride and joy will have to sit still for a few days. This will give you time to maybe carry out the oil service, give it a polish and slip on its track tyres, ready for the next track day.
