I had the LAD 200 conversion on my mk1 172. When I got the car back I noticed an oil leak. Phoned & emailed them quite a few times but was fobbed off. In the end I had to take the car to Hillpower where Nick proved beyond doubt that it was an incorrectly fitted exhaust cam oil seal. I sent the pictures to LAD but they still wont accept responsibility.
This is just to warn other people against getting any work done by LAD, there customer service is rubbish!
After the mods made at Hillpower my car is really quick. I think the group n cam has made it an ideal car for fast road use.....
