It needed to be replaced with the new one; it developed a crack over the years that has leaked oil; the engine is approaching 220K mark and I wanted to share its condition with the community.

Looks good to me -- a slight varnish here and there but overall... thumbsup

What vehicle, oil and OCI?


I use the overseas manual to choose my oil viscosity.

yes; I've used for its life dino, semi and lately synthetic only; I did not stick to the specific brand as long as it was 5w20; oil changes performed at 3-5K for time being; it is a MZR generation, the Mazda engine

i've noticed darker camshaft, facing the front of the vehicle then the one next to the exhaust for some reason

How common is a cracked valve cover? How much will you save by doing this job yourself?

I did the same in the past; unfortunately, the valve cover on my car is made by plastic; I hate when an engine drips the oil so I did replacement; 14 bolts altogether, easy job to do, less than 2hrs

If you want the job done right......do it yourself.

I honestly thought I was looking at a Ford Focus engine!
My 07 looked almost identical when I replaced the valve cover gasket (also a plastic valve cover).

its no wonder they look the same; it dates origins back in the day when they were assembling these in Michigan

I don't know how common a cracked valve cover is. As for the cost savings I'm sure the stealership would charge at least an hour labour, maybe more.

To me the experience working in your own car can't be measured in dollars. It's priceless to me even if it throws challenges my way working on rusty and siezed nuts and bolts.

What is the "bladed thing" at the right end of the intake cam?
It's clearly visible in pictures 1 and 4.

I'm guessing it's part of a counting/positioning system.

Not bad looking .

Don't you love it when a plastic part goes bad & the old style metal equivelent never gave any problem ?

There's nothing quite like the feeling of a job well done on your own stuff! Pulling it out of the driveway after cleaning up feels glorious!
