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

done

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.

man,i'll look for this i couldnt see any such marking....
but now that i know its on theplastic cover..below and to the right 
of the tensioner? where ballpark am i looking? and the hash mark to 
line it up is on the actual crank puly? the outside one or the inside 
one?

yup
yeah i bought a timing light and set it..now the timing mark is a
'gash' in the flywheel correct? I hope i lined up the right mark!

seals are good, even if they were bad that shouldnt cause such 
insanely poor performance.

I'm betting slipped timing belt..i fit did slip a tooth..or 2 anyway 
i mashed a valve? how far does the timing have tobe off to interfere?
