I need to keep this from becoming a bash thread on the shop that built my core.


I have a 13b street ported core. I was told the shop was great at motors but I think they over ported my core ? My understanding was they use the Racing Beat templet, but I didnt know they went past the templet and did a "custome " job. God knows why they do that, they are not experts at fluid mechanics.

I seem to blow smoke only when I sit at idol and never more then 3 seconds worth . My oil consumption is normal but I only blow smoke when this happens. I understand oil is injected during the combustion cycle but is a possible overlap due to the porting being to large causing the oil accumlation ?

The core holds vacume and boost great. I have under 10k on the core. Any ideas if overporting could cause this?

if overported...the oil control ring will slide over the intake port and can drop oil.



you can see the oil track rides along the intake port, if they ported into that area you can have problems.
