Default Blue smoke... Rings OR Valve Seals??

i havent cheked the compression yet.. im gonna chek it today or tomorrow but i took a vid of it smoking.. the pass. side smokes worst than the driver side.. it was smoking before but way less.. now its getting worse and worse.. i talked to the engine builder he said the valve seals went on very tight and they where not the correct ones he gave me the correct ones to order now if thats the case

0.500 guide
11/32 stem + .010


and i found plugs 1.4.6.8 Wet.. ( oil )
before only plug 4 was wet..
ow and btw the engine did not lose power!! but still im going easy on it and not driving it anymore

Not the correct valve stem seals is a hint. You can always blow air into cylinder to hold valves up. Take off rockers, valve keepers, springs, and replace seals without removing heads. Then have a serious talk with machine shop that installed incorrect parts. This was avoidable.

why is it oily in a few intake runners? specially nr 4cyl the one plug i always find with oil! its oily in there but not in the intake itself... i suspect the gasket was leaking..

i noticed something today... when cold it does not burn oil .. i drive it a little and give it a few revs let the engine warm up ( its NOT low on power i may add ) and it started smoking.. my money is on the intake gaskets.. ?

Question. Were the heads resurfaced?( Shaved down to make flat.) You can use mustang metal type valve cover gaskets that can be reused. Clean the mess out of intake and head to intake mounting surface. Use RTV on block ends not the gasket. Follow torque sequence and specification.
