Tappets noise and emissions failure
I just bought a 1997 spider and I am in the process of restoring it. The car had a turbo on it but now it is all stock. Also the car was on a parking lot for about 2 years after that.
Recently I changed the distribution, oil, oil filter, MAF, lambda sensor, thermostat and cat. The tappets were cleaned and I replace one that was stuck
The car also has a tappet noise when the engine warms up. Cold, the engine sound as good as new for about 5 min, then the tappet sound comes in a never goes away. I try 5W40 oil and 20 w50 with the same results.
Also the car is failing MOT emissions.
I really donīt now what else to do. I would appreaciete any help in the revival of the nice car.
