I have a very unusual issue with my 89, it has a pronounced knock at idle only after it has warmed up and has been driven, other wise it is running great.
Here's a video of the knocking...

I've googled the problem and since it doesn't knock when it is cold and when the engine is above 1000 RPM it doesn't seem to be bearings or rods since every article stated that the noise occurs at start and through the RPM range.
I've come across other articles that hint that it may be header or exhaust system being loose and knocking on something. I've also came across other articles saying that a cracked flywheel may cause the same issue.
Here's what has recently been repaired and replaced...
Prior Work:
1. Replaced Clutch, Fork Clutch and resurfaced Flywheel
2. New Exhaust from Headers to new single
Catalytic Converter
3. New fuel filter and injectors cleaned
Stats:
Oil level and pressure OK
Oil and Coolant temp within norms
Just over 70,000 miles on it...
Babied and never mistreated.
I keep seeing that if there is real trouble with the engine I should be hearing the knocking at first start and through warmup, and since isn't the case, I'm coming back to you all to see if you've seen (heard) this before. Thanks bigtime!!!
