So I just had my engine pulled out of my '83 Brat to replace the rear-main seal. Turns out it didn't even have a rear-main seal. Anyways I also found out that the entire EGR system has been plugged. The EA81 in this car is not original so I was wondering if Brats had an EGR system in 1983. If they did, then my engine has been swapped illegally and won't pass inspection; however, if they didn't, then plugging up the EGR system makes sense and is legal. I need to know fast, so any information would be greatly appreciated!
