Friend was following me home from school and said it would smoke a little bit (blue) when i start out at a light but other then that its fine think its running rich? its a 5 speed F22 any tips would be great thanks

 

From the description, I think it's highly likely that it's oil pasing down the valve guides because the guides are worn, and / or the valve stem / guide seals are worn. If this diagnosis is correct then you might also expect to see some exhaust smoke at higher rpm with the engine on the 'overun' (i.e. engine rpm significantly above idle but with the throttle closed and the car slowing with 'engine braking').

 

I was thinking it was one of those 3 but im not sure he said it only smoked when i started out at a light and no other time, engine braking higher rpms nor when shifting in lower gears

 

A classic sign of worn valve stems / guides /seals is smoke fom the exhaust when you get BACK on the throttle AFTER slowing using the engine braking effect. This is what I meant in my earlier post, but wasn't yet awake enough to describe correctly...

It's caused by a relative vacuum in the manifolds causing the higher pressure in the crankcase to more easily 'pump' oil (and blowby gasses) through the oversize clearance between the worn valve stem and worn valve guide into either the inlet maniflod (and from there into the combustion chamber), or into the exhaust manifold (where it's burnt by very hot gasses once the throttle is opened again).

If the valve seals are worn then this may occur to some degree, but if the problem is significant then it's almost certainly the stems and / or guides. In this case fitting new seals may fix the problem in the short term, but not for long.

 

Yeah we tore apart a f22 in auto tech class with brand new valve seals in it i might ****** them
