    Hi everyone.
    I have a Audi A4 Quattro from 2001 with some problem. It's really hard to start, runs really rough and white/blue smoke a lot. The problem is something with the intake valves at the right side cylinder head. I made a leakdown test through the injector and all air went out via the intake valves, but when I removed the camshaft it was sealed. It builds great pressure in the cylinder.
    Anyone got an idea of what the problem is?
    Regards from an clueless swede

    AKE cams and fingers suffer from terrible wear problems, sometimes so bad that I have seen three or four cam fingers thrown out into the head and just lying there.

    the camshafts and fingers/rocker arms have recently been changed on both sides by the previous owner at a garage, meanwhile they lifted the right head and changed valves. The problem is that the valves don't close when the camshaft is mounted. But when I remove the camshaft the valves seal properly. Could the problem be something about the hydraulic tappets? I don't know if they also were changed or if they are old.

    Is it both sides where the valves do not close? You could do with finding out what was fitted, part numbers/make

    Only the right head leaks, don't know if exhaust valves leaks since I haven't taken of the exhaust manifold but I don't think they leak. The cams are bought on eBay but are supposed to fit the AKE engine. I don't want buy new cams because they cost over 1700€ in sweden, and that's about how Much the car is worth in good condition.

    It could be that the wrong profile cams or followers have been fitted.

    Do you know the dimensions on the cam? I have searched a lot but haven't found anything.
    Maybe when the garage fixet the head they regrinded the valveseats so now the valves gets too long? I will try to compare to the other head.

    Are the intake and exhaust sides using the same tappets and fingers? Or are they supposed to look different?

    All 24 are the same BUT there are two different designs of cam, equaliser and finger.
