My next question is, how the hell would a bearing fail with only about 16K on the engine? And the oil checked and changed religiously?
Also why am I getting great oil pressure? Wouldn't bearing failure read low pressure? Or no pressure? That sucks, because if it is a bearing that is going to be alot more expensive to rebuild than I had planned.

Bad install, bad bearing to start with. Blocked oil passage. Anything is possible.
Yes oil pressure should usually give you some indication. If turbo isn't coming apart not much more that can cause that kind of noise. Fuel delivery or ignition issues usually don't sound like a bad rod. Could be quality of sound on vid but sure sounds like metal on my computer. Air pumps can make really nasty noises especially when they shuck a seal. Parts get stuck in the ACV and cause rough running. Partially blocked exhaust will cause lack of top end power, but you would notice higher water temps when run for any length of time. If you can get a hold of the old tape compression tester to use it gives you much better read out for diagnostic. |

Check your electrical connectors on the injectors and make sure theyre not damaged, all of them get 12v with ignition on, and if you can see if the ecu is opening them when you try and start the car. As long as you are getting spark to both leading plugs i'd say it's fuel.

I think I found out what the 'hammering' sound is. The AFM and air filter are not securely mounted anymore, and the end of the filter was knocking against the inner fender. When we I fired it up to move it onto the trailer, I held my hand on it and that sound went away.
Whew.

Since the AFM wasn't set securely, and was banging around like my ex, then would it not make sense to check/replace the AFM to ensure it's working properly?

Finally got around to compression test yesterday.
All good on both rotors. Spark is good, so its time to pull manifold and check injectors.
