Sisters BRM has what sounds to be a smashed lifter. When I'm engine braking and downshift and the revs go up around 3,00rpm, I can hear an intense valve ticking. It alarmed me at first because I thought it was rod knock, but after hearing it, it's definitely lifter tick. Cam is original and car has about 370,000kms on it. No performance issues or MPG issues. Still will accelerate awesome and get 50mpg all day long. But we looked into a Colt cam and for $700 you can't go wrong, especially considering we don't need to ever worry about the cam again. So with this, I read some charts where some people gained 10-20hp. Is this true? And does fuel economy improve/decrease? Can't seem to find anything on fuel economy. And we should stick the the 5W40 505.01 VW spec approved oil?
