I have a lq4 bored and strokes to a 408. I'm using wiseco pistons and eagle rods and Callie crank. The rings are gapped for boost but am not sure the exact gap . The problem is I'm buring a ton of oil I am running vr1 20-50w oil . I have driven it about 60 miles it has a lot of blue smoke coming out of the exhaust at idle and under heavy throttle in the beginning but clears up. Any help would be appreciated

 

No I had a engine builder do the short block

 

I have stock 243 heads with light porting I am thinking maybe they put the wrong valve seals ?

 

all 8 spark plugs drenched in oil

 

Did you use break in oil , isn't the vr 20/50 synthetic oil , you should use regular oil to break in the rings then after 1000 miles change the oil and filter

 

Well on initial start up I used Joe Gibbs br30 and no there is vr1 senthetic and non

 

check to make sure the valve seals arent damaged or are missing their spings.

 

Sounds like seals are not seated. Also you should use thread sealer on the rocker bolts. The hole is not blind you can see it over the intake valve. Hows your pcv system?

 

Rings are already set, they will seat up after 5 minutes..

But yeah drive it like you stole it

 

Could be lots of things...valve guides shot; improper hone finish for the rings
used; way too wide of gaps; rings upside down;....generally speaking low
tension piston rings control oil better that is thinner like 5W30

 

Sorry been really busy just turned out the Pcv system was messed up I had the fresh air port going straight to the intake manifold scence I fixed it I put over 100 miles and no smoke
