Thread: A history question from the "wife" and "husband" in AZ

I understand your point perfectly, as they follow the cam just like a lifter. But they don't 'lift' anything. They just keep the clearances between the cam and the valve assembly adjusted. Hydraulic lash adjusters do it one way, solids a little differently.

I would...

Since Japan forces vehicles off the road (or makes it very expensive to keep them on the road) after a certain age, there is a big source of fairly low mile parts coming from there. What the kiddies get all spun up over is that the motor is 'JDM',...

They were correct (although I thought the toilet bowl badge was added to the front bumper in 1994 it could have been in 1993). It should NOT be on your 1990. If I saw a 1990 with the emblem it would make me wonder if the front bumper was replaced due to an accident in the past?

My '90 does not have the emblem. I am not the original owner, but there is no sign of accident damage or repair and the rear has not been de-badged. So, mine does not, but not entirely sure whether it should. Sorry, not much help.

kj7lo, The NA6 (1990-1993) has the cooler decal "Mazda" on the driver's side. If I were to put a badge on it I'd put the Eunos "V" badge on it.

For the North American, European, and Oceania markets, all years of (1989) 1990 to 1992 were without emblam on the nose. Only the Japanese market Eunos Roadster had an emblan (no Mazda identification at all, actually), which is a V within a circle. All other cars should have a "mazDa" script sticker on the driver's side. For 1993, Mazda adopted the "tiolet bowl" logo...which adorned the car until 1997....

Yours should just have a MAZDA lettering sticker on it on the drivers side
