The AFR matched from the Dyno and the FI controller, but it turned out to be TWO loose plug wires (as described above), so I'm replacing the 90* plug wires with 45* wires to keep tension off. We'll see. Sometimes it's simple things. It's definitely running rich - when I let off the accelerator I get small backfires from the pipes.
As for oil, it gives a little puff of smoke when it starts, but so does my new Mustang. I also think it might be one of the valve covers leaking but haven't gotten there. I agree about the dye kit. That's on the list. The engine takes 11+qts! |
The dye kit works really well, but it doesn't always isolate the root cause. For example, I had a problem with a leaking
oil galley plug and they ended up needing to pull the trans out to fix. I did isolate an
oil leak on a valve cover gasket that was causing a mess.
