Camshaft error? help

[haybayian]

As indicated earlier the shop that sold me a remanufactured AAZ borrowed parts from another VW diesel without being specific. Could anyone here tell me if it would be possible that they may have used a camshaft from a TDI and is it different?  I would like to ask the same question about 1.6 TDs camshaft.

Thanks,

There's not that much difference in the cams: maybe the lift, duration, or intake/exhaust point is slightly different, but for the most part, they're interchangeable. I personally have a 1.9 TDI cam in my 1.6D with hydraulic lifters (cheaper to buy that than a new one for a 1.6). Anyway, there is no interference issues, and the engine runs fine. It did however change the power profile a bit. I think total HP is the same, but the motor is more responsive at higher RPMs and a little less torquey. It's great for highway cruising, but a little less powerful/fast on takeoffs. Nothing major, just notable.

All 1.6 hydro cams carry the same PN (NA or TD), and all mechanical 1.6 cams carry the same PNs (NA or TD). I've heard of guys swapping between mechanical and hydro no problem.

So, if your motor is running like poop, it may not be the cam's fault (unless it's bent or otherwise damaged).

Thanks for your response. Yes I heard from others too that these cams are pretty similar. My understanding is that diesels do not lend themselves to much  cam profile fiddling. They have no overlap, and presumably  have been designed by the manufacturer to take advantage of lower band without sacrificing mid range performance. In that sense my understanding is that diesels are quite different from gasers. In the big picture, there is little difference betwen a 1.6 TD 1.9 TD and 1.9 TDI I think.
