Title: Valve stem Seals on 2007 GTI
Post by: Mego on January 31, 2016, 07:36:02 pm

Hi all,been having bluish smoke issue while going downhill when off gas,and when i push the gas a little a bluish puff of smoke came out and then disappear.
i did change the turbo and nothing changed..then i did a full pcv delete and same problem is still there..yesterday i did a compression test wet and dry and all is ok (153,150,150,148).
my question is could this be a bad valve stem seals?is it known that seals go bad in tfsi engines?
i think the only option now is the valve stem seals.

BR
