The daily. It "chugs" a bit at low rpm, its slow to rev on heel-toe, and feels almost normal at 4500rpm+...which tells me its off a tooth no matter what the timing gears look like. I'm going to take it all apart tomorrow again.

I'm starting to wonder if the CAS is off, I'm definitely at TDC on all 3-gears after 2 rotations and it matches the turbo car.

This motor has always felt sluggish so I wonder if the previous owner was off one tooth on the crank and I've never known any different? I guess I have to bleed more money on tools.

BTW, sears has stubby gear wrench sets for $25.

Should the cam lobes be at rest or on the spring? Right now I'm on the spring to put them in the position posted earlier with the "pins-up" and the tick marks on the cam at vertical.

Want me to make a datalog? Any tips on balancing the cam gears?

Go get a new timing light and check the timing. I think your CAS somehow got moved and timing is off. I had the same issue on my 1.6 DD when the CAS had timing retarded.

Also and easy check without a timing light is to loosen the CAS and slightly turn it each way. It should get to the point that timing gets closer and starts to sound like it is running better. Just make sure to jump the 2 things in the diagnostic box.

It turns out the previous owner had the intake cam off 1-tooth and that's why the car always ran like **** and why I thought the motor was bad. Now that I adjusted the CAS the motor feels strong for an NA car and will probably get better MPG too.

I drove that car for 3-years with shitty cam timing, lol.

So youy are sating that you fixed the intake cam and then readjusted the CAS? Its always the stupid **** which gets you.

So much for the old butt dyno!

Think I'll stick to datalogging.

A long time ago I adjusted the CAS to 10* so it would stop detonating. Fast forward to this weekend where I set the motor to TDC (every time) on all 3-gears and it barely ran...until I adjusted the CAS with roughly 6* of advance adjustment and suddenly it drives the way a stock motor should.

Before I set the engine time the CAS was cranked over as far as the wire harness would stretch, now its back to the more normal looking position.
