Ever since i bought my camry new i have been dedicated to my local toyota dealership as far as routine service, state inspections, and preventitive maintenance. I've never taken the camry elsewhere. I recently got some 60K interval maintenance done by the dealership a few weeks ago.
Anyways I was cleaning under the hood some the other day and noticed
paint dobs in different colors on various areas on my engine. I have never noticed these markings before. Don't ask me why i haven't taken notice.
What do these marks mean i hope its not bad. I'm kinda fearing to ask the service advisors at toyota. Anyone on here have these marks on your engines? i have searched TN with no luck
