NEED HELP.

I assume the butterfies are the flaps. There are two screw to take the top bracket and gasket off... is that all to be done ? It doesnt look like those flaps even come out.

Over 40min of driving. Really don't think a tune will fix 700+knocks. I had none on all other cylinders. I have weeded out a few causes. Compression and leak down test coming soon. Possibly too tight of a valve adjustment on cylinder #1, leak down will tell.

The problem still exists. There is also no smoke from the car, in regards to oil rings or seals. I'm Fuc$ing lost. Simi brought up a point that maybe, just maybe the ECU is bad. No way to know if the knock was present previously. And yeah, this J30 may be on the way out.

Causes eliminated
- spark plug
- coil pack
- checked for loose wire
- moved injector to another cylinder
- re checked timing (on advise from Tuner on lack of power, all good)
- found smudge on cylinder#1 valve, cleaned off

We can call off the dogs. Anyone I sent an email datalogs, don't worry about it. Compression test ran.

5 crank and 10 cranks done. Need a better compressor for higher psi to run the leak down. Pretty sure it's the heads, no oil consumption or smoke. Leak down will tell me.

The Good - Compression is back up to 210psi on cylinder #1.

The Bad - The DAMN KNOCK is still there!



I dont get it, if someone has any idea as to what this could be, please chime in. Maybe a slight bur in the combustion chamber ??? IDK

Oil Catch Can just installed. It gotta say my routing ended up looking pretty cool. I have another to put in the rear valve cover breather.
