Hello Everyone! So alright so i have a 1994 Honda Civic Coupe Ex, It's a manual transmission, I love this car I've had for about 5 years I've replaced the clutch 2 times already. The mileage is at 280,000. I haven't modified it so its still all stock. I'm about to replace the Head gasket and valve cover gasket soon since its leaking oil into my radiator reservoir. Whenever i have to have emissions done i have to retard the timing or else it fails because of high Nox and I've pretty much done everything i can think of to help it and nothing else seems to work other than to retard to timing the minimum. I know in a couple of years i'll probably have to part ways with it but i really dont want too. So i need some suggestions as to what to do to keep this car around for way longer!
