Well, my new chip is ready.  Unfortunately, the weather is not.

There are entirely too many parameters to adjust.  Hopefully, things are right, this round.

The new chip, with the new programming, is installed.  No SES light, no dying, and no rough idle in gear when stopped.  Started and ran cold.  Of course, only 40 miles, so far.

I've been trying to find the oil leak source, but not lately; however, these pictures seem to indicate somewhere in this area.







That looks really nasty.

Crankshaft/timing cover seal?  Maybe the crankshaft has a groove worn in it?

It sure looks rotational.

The crankshaft is supposed to be new.

Off and on, I've been testing my Fiero from a cold start.  No issues, thus far.

It looks like a damper with timing mark and too much oil leaking out.

So, the timing mark is almost aligned with the inspection tube?  Not that I need that notch.  Is that part with the notch the outer ring that slips?

What is that thing with the notches?

I'm going to deal with the oil.

The tube is used ONLY with the factory timing system.  When using a conventional timing light, the timing mark doesn't line up with the tube as your picture shows.  The serrated piece (with the notches) is what you use to time the engine with a standard handheld strobe timing light.  With the ALDL jumpered, the deep notch will line up with the 10 degree mark on the notched piece.  The notched piece is actually marked to tell you what degree each high point represents.

Several times today, I started my Fiero, and let it run until it got up to temp.  Each time, the engine started right up, ran smoothly, and had no trouble on tip-in.  Hopefully, this means that the run-ability issues have been resolved.

I need to do some fuel mileage runs, but after the streets dry up.  It's rainy and nasty outside.

I ran my Fiero long enough to warm the coolant.  Actually, the temp got several marks above 220.  The Fiero was parked, and air temp was below 30 degrees.  I shut the engine off, and grabbed the upper radiator hose.  Cold.  Computer shows temp is below 185, thermostat shows temp is below 185.  I have to believe there is a wiring issue, somewhere.

How long did you run it? Even in cold weather, the hoses should get warm after a while. If not, there's either a blockage or the pump's not pumping.

Well, there is heat, so the pump is running.  The radiator hose should only get hot after the thermostat opens.

After shutting off the engine and restarting, the temp gauge showed a much lower temp.  The radiator hose did eventually get hot.

If the balancer was replaced, but the seal in the timing cover was not, would there be a good seal?  Let me think...  I suspect not.
