The Toledo is sounding a bit like a non-serviced Endura engine all of a sudden!
Oil is OK, bang on maximum. Weird thing is, with the windows open it sounds OK, but with them closed and nothing on you can really hear that typical valve train noise (I don't know if it is VT related, it's just the closest noise match)
I believe it has hydraulic valve lifters (Is that the right term?)
Had the timing belt done a while back but I remember from my Peugeot days that something TB related can also make a noise like this...
Any ideas?
