just started making a loud knock thats coming form the drivers side head
it was only making the knock upon start up and the first 10-20 min of driving
but now its constant???
my friend said maybe needs valve adjustment???
does any one know if this EA81 engine has hydraulic lifters???

as for the knocking it does sound like Hydraulic lifter kind of thing.
If you suspect Hydraulic lifters making noise, use some Sea-Foam through the engine to help un-stick the lifter if that is what you have.
If it still knocks I would remove valve cover and take a peek and check for any sign's as to why it is knocking.. This is a simple thing to do before something really brakes. Call local parts place for gasket. If cork, cover in Grey High Temp RTV, let dry and install. .02 cents

i would go with frequent oil changes for now and possibly some "treatments" like sea foam (excellent stuff) or marvel mystery oil.
whatever you do, keep changing your oil regularly and often. the HLA's don't do well with dirty oil.

i will run sea foam and then change oil
is this engine on its way out???

but this is much louder and only on the driver side head
its constant now but was only making noise at start up and first 10 min
car is not being driven until oil change and engine treatment

They are bullet proof engines. Anything 280,000+ is getting old.
