Here is Mazda Timing Marks for timing
See if this helps
Here is diagrams
Please read & understand the above procedures, as that is directly out of the:1998 Mazda Protege L4-1489cc 1.5L DOHC MFI ManualWhich is a DOHC
One Cam is Chain driven, one Cam is Belt driven
Please verify Year, Make, Model & Engine.........
1.5 has always been Chain & Belt DOHC
Your description sounds like a 1.8???
Sorry for the problems.The only other thing I can think of is if this is an Import / Canada vehicle
Here is the 1.8, see if this is what you have
Did you view the above 1.8?
See given answer
In found these marks for a 99 Protege , in 1998 they did not even offer a DOHC for PROTEGE. Now do not get upset I am just trying to help save this one. 1999 is the year they offered a DOHC engine.
THEY OPTED OUT BRO
I saved the question, you simply put (ACCEPT) by my answer...
HAPPY THANKSGIVING, hehe
