E30 M52 Power Loss Sorted, Time To Drift

E30 M52 Power Loss Sorted, Time To Drift. Finally sorted the lack of power from the engine today! Yesterday put the Beemer on the exhaust gas analyser at JTs garage. Yes it was running rich but not excessively. No codes coming up on his scanner either. He gave me the number of BMW specialist at Highyms park. Gave them a ring and explained the symptoms.

He said he couldn’t do anything until Monday and it would be £60 an hour + vat to run a full diagnostics as it was a conversion they hadn’t dealt with before.

Well I didn’t fancy them numbers….was going to drive to Wembley to meet Oz from the E30 zone who had a new camshaft sensor I could try.

It was another really hot hot day and on my way to Enfield there was a lot of slow moving traffic. The engine was losing even more power, now holding back from 2000rpm?? Continue reading

BMW E30 M52 Conversion part 3

Back again for my BMW E30 M52 Conversion part 3. Hmmm the conversion is dragging on a bit longer then I thought it would. I really wished I won the eBay auction for the M52 conversion a few weeks back, would of been up and running by now!! Anyhow The plan for the 3rd week was to get the:

  • Gearbox fitted
  • Prop Shaft bolted up
  • Exhaust modified and fitted
  • Coolant Pipes sorted

1st Job, Get the Gearbox Jack of JT before he disappeared again. Just caught him before he left and got the G Jack! After a bit of running about for Marsh (Rilus) I was ready for action. By the time I got started after a late lunch, it was 3pm! Damn…

Marsh helped me tow the Bimmer over and got her on the ramp. 1st job was to remove spigot bush bearing from crankshaft. Easier said then done if you don’t have a spigot bearing puller.


After some chiseling and drilling, it wasn’t looking good! I was going to try the old school trick of packing grease behind the bearing and then tapping the clutch alignment tool through the bearing which compresses the grease forcing the spigot bearing out, but this method can be a little hit and miss.
