OK i did my LT4 cam kit swap, cam/springs/rocker arms, i reused the valve seals. i know there bad and i have replace 3 cylinders so far. When i punch it smoke comes out the back like burning oil from the seals sometimes. everytime i punch it to like 90-100 tons of smoke comes out. It looks like i was in a burnout pit.... any solutions. or just think its the rest of my valve seals

 

They would have to be very bad - valve guide seal leaks usually show up as a puff of blue smoke at start up. To test for leaking valve guide seals on a used car, I let the engine idle at least 30 mins, then I rev it up to redline...a small blue cloud indicates that a test drive is needed. Go out and drive the car hard, if you get blue everytime you punch it, it is very UNLIKELY to be valve guide seals, it's hard to get that volume of oil to leak past them.

If you get blue smoke everytime you floor it during that test drive, I'd suspect rings or intake manifold gasket leak. On our engines (unless some builder mucked it up), rings are unlikely. Suspect your intake manifold gasket.

Put a wrench on your intake bolts, are they tight? Even the ones over cylinders 4, 6, and 8?

Hope this helps. - JM.

PS - why would you not replace you valve guide seals while you were replacing your springs?

 

Because im not smart. but could the rockers be unadjusted correctly causing valve float........ I had my mechanic do it and i help/watched him do the intake manifold... Im not leaking any fluids at all if that helps. but yes i do get the blueish smoke at start up then goes away a few seconds later. but i know those are bad

 

Valve float won't cause smoke. - JM.

 

well i really need this answer or some solutions. my non high speed runs are killing me

 

Jake, did you put your intake gaskets in dry? or did you use a coating?

If I was you, I would yank the intake and see if oil is getting sucked into the intake ports.

 

Intake Gaskets Went In Dry...... Its Funny How It Only Does It At 90-100 Mph

 

Anything Anybody

 

Well last night i ran into an 06 subaru STi. from a really low roll i owned him once i hit about 90 again this time smoke was comming into the car. its getting bad guys i need this fixed. could me header gaskets be leaking

 

could anything have to do with the air pump still on with it just open because i have the plugs in the headers for them and/or could it be i have the intake manifold egr blocked off
