I had not thought of timing issues. But I redid all the vacuum lines some time ago with nice silicone lines. There is no effect on the air/fuel ratio since the air leak amounts to the same thing as opening the throttle blade. As load increases it will go down, sometimes even briefly negative. However, while fair wear and tear on engines is unavoidable and modern ECU's are programmed to compensate for increased oil consumption rates, sensors losing sensitivity, and other factors that affect fuel trims, ECU's have a limited capacity to compensate for some factors, so keep the following in mind when interpreting fuel trim values-. If some of the air bypasses the MAF sensor, say through a torn intake tract boot or leaking manifold gasket, the ECM has no way of knowing that and will only add the amount of fuel required by the air mass it does know about.
