Catalytic Converter, O2 Sensor & EGR Questions

[fixkick]

SOME of those headers made by Doug thorley are not made now (too few cars on road running I guess)
do you have this slot?


this header  has the magic hidden EGR slot..(and matching new gasket for that , calif CARB certified,  DO YOU have the slot; SOME DO NOT.

THY-716Y-C (or  THY-716Y-SS)   the SS I think is still made, for sure sold.







as you can see this 16v engine had 2 kinds of header,short and long, (calf, and fed)
long tube headers started in CALIF 1992 and later all cards when long.
ending this mess (fails hard) (had after burner plates inside the melt and block exh, flow, yah super bad.. long header is best, and not use  below #1 part

next up CALImini. 

long ago  they made these too  and are very good.

look for the tube   #4 port, seen at rear, here os CALMINI header is EGR fitted. SK703Y-S

My header does have that slot. Also to bring you up to speed where I am at with it now, I got the new cat. It is not melted and is installed properly now. PO removed. Prior to that I checked main cog for damage, replaced the pugs gapped .28 and wires installed properly, I replaced the timing belt but did not move the main and cam crank independently, I set valve lash to .06 but they were only off at .05 and or 0.07 so not much adjustment. The vehicle ran before but will Crank and not start now.

Assuming that all my work is correct could the new cat be the reason for it not starting. Before you answer a little back story. After vehicle would not start I started looking around the engine bay. I found the EGR disconnected from the block with all wires and hoses still connected. It seems that the PO removed the Cat and the EGR. Could the EGR being removed be the reason with the new cat that the vehicle won’t start?

THE EGR REMOVED LEAVES A HUGE HOLE IN THE INTAKE, VERY BAD THAT.
.05" is match book cover thick dont you mean .005" THICK?  or are those metric number?
