Right, so today was also a story of ups and downs.
This is a guide based on my experience of rebuilding an S50B30 vanos using the Beisan System kit.
These are one of those things that you tend to forget about, but changing the old and worn out ones for new ones can do wonders to uplift the interior. Its cheap and easy.
This is the one thing that all E36 coupes should have come with. An Armrest.
The cars I have owned, past and present, in chronological order.
Sub-Four Wheels of Fury.
They aren’t cars (or if they are, they are the Reliant Robin), and they have less than four wheels, but I owned them.
Cars I didnt own, but had a big part to play in my life.
The S62B50 engine as used in the E39 BMW M5 is designed for some pretty heavy use. One of the features the crazy guys over at the ///M Division put into this engine to make sure it can last longer during a good thrashing is a pair of oil scavenge pumps and a pair of control solenoids.
The main function for these is to keep oil going to the right places under heavy cornering. Most engines unless they have a baffled sump will tend to have the engine oil slosh to one side under heavy cornering. Some cars (including the BMW V8s) also suffer from oil building up in the heads and unable to drain. This means disaster if it causes the oil pickup in the sump to draw in air instead of oil. Its a very quick way to running a bearing.
A solenoid will activate at over 0.9G of cornering force, allowing the scavenge pump for that side to draw oil from the engine head and return to quickly to the sump. This helps to keep the rear of the sump topped up with oil and keep the oil pickup submerged.
Just goes to show how far the ///M Division went in order to make this engine special and make the E39 M5 the beast that it is.
Chucked the Actioncam on the back of the M3 the other day and recorded the exhaust. Standard exhaust, cats have been replaced with resonators. No O2 sensors, so running a bit rich.
Has a hearty rasp, thats for sure!
Right, so the moment i got home today i decided to carry out some work on the M3.
Since i got the car the heater hasnt worked (i knew this when purchased). Neither side changed temp at all, just stuck at cold. I knew this was the heater control valve (HCV), as they are a common failure point as they are easy to block and jam. I purchased some parts from Ray at HellBM, which included a replacement valve.
Its not a hard part to get to on the M3, just a bit tight due to the header tank, and there isnt a lot of space to twist and pull the hoses.
