Valve Cover Cleaning (Inside)

[fixkick]

Thank you for the info. At least I know what it is for now.

I thought it was weird that they made it non-removable.
(that is because it lasts the life of the engine, and who wants screws falling in to said engine?)

No machine shop within 200 miles of my place.

I used my sandblaster on it and got a lot of sand stuck in the gunk under the baffle.
never ever use sand blaster inside any engine, it fractures to tiny imbedded, in the metal, the works out as you drive. this is well known
what is better is walnut shells, never sand and never glass beads .
keep all forms of silica sand out of any engine!! this is like RULE1, (0utside ok)
we have microscope views of this damage, its not pretty.


That is why I took it off to clean.
It is the 16 V model.
I was thinking of leaving the baffle off, but now I understand its importance and I need to reattach it.
i can not think of one extra part in this car, no extra parts, at this price, range. I can think of things needed, not put on car... HD stabilizer.
every part of the engine has a purpose, for sure. just ask....

Do you know how/what they used to fasten the steel baffle to the aluminum valve cover in the first place?
They do not look like any kind of rivets that I have seen before.
those are Japanese rivets, there is no such thing in USA. In Japan, they have many things not here, vast things, I lived there for 1 year, so...

id leave it alone the varnish is harness, it's very thin. all engines have it, all with say 150k on them, its totally normal.
id spend my time getting the EGR paths, super clean before ever worry any PCV buffer.
look for broken head rocker springs? the are rocker guide plate springs, some break.
new valve seals.
fresh water pump, made in japan not china?

and making sure the .050" head orifice , never gets clogged up and cam starves of oil.
there are my tips
good luck !!!
