But when I did my smoke test, shouldn't smoke have made its way out if that lower intake leak? I had no smoke anywhere...I even took it up to the local garage and they ran their smoke test and had the same result, nothing. It's quite weird to me. But yes, it has a very small slow oil leak from the back of lower manifold, and has lost a lot of its low end power. It use to rip right off the line, but now doesn't seem to pull hard until hitting close to 4k rpm. And the idle surges like it's a huge solid cam which it's not...just a tfs stage 1. Now, it hasn't been tuned yet, but it still idled somewhat decent without being tuned. So I know it's not a tuning issue</p></blockquote><p></p>
