FAQ
Anyway, seen some fella doin it on youtube and looked like a handy little diy job with carb cleaner etc. So pulled the hood and looked at the back(left hand side) of the intake manifold and there it was, "gone". No EGR valve.
Stuck my head in for a closer look and it seems that it has been removed and blanked off.
So I have a few questions about this: (the car is a 1998 Jap 1.8 mk2 RS 6speed)
1. Do JDMs of this year have an EGR valve, if so then it was obviously removed and blanked by a previous owner.
2. Looking at the close up image, should the other hole between the bolts also be blanked off or is it ok as is.
3. Is not having the EGR going to do any harm to the car in the long term.
The reason I ask is that I had to replace the CAT about a month ago for NCT as high idle emissions were sky high and CAT was fecked. Would not having the EGR valve damage the CAT over time.
The EGR valve apperantly does the folloing:
"The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. This results in a cooler, more complete burn of the fuel which decreases you car's noxious emissions by prohibiting the formation of some harmful gases. The EGR valve is vital to your car's emission controls. Exhaust gas recirculation helps to keep huge amounts of unburned fuel from being released into the atmosphere. This unburned fuel is thought to be a huge contributor to greenhouse gas build-up. That's why an EGR system became mandatory on all new vehicles some time ago."
