yesplugs are dry, no oil in coolant no smoking car.

i looked for the dot too, couldnt find it will relook.
..oh a note..my TT ajust cam sprocket..is backwards? I assume the
sprocket is concentric where either way the offset is the same? Oh
its not on the car yet. but hehe the dot is on the outside and the
two hash marks are on the inside.

but now that i know its on theplastic cover..below and to the right

seals are good, even if they were bad that shouldnt cause such

I'm betting slipped timing belt..i fit did slip a tooth..or 2 anyway
