Got any pics?

 

didn't think about it.... I think there are three holes on the solinoid the screen is on the bottom. It says in the helms manual taht the screen should be cleaned from time to time....

What did you find in yours?

 

just stuff..very fine dirt......

 

The "stuff" is sludge. Have you been changing you oil regularly?

Clogged VTEC screens are usually found on cars without frequent oil changes. I've cleaned plenty of them.

 

Yes sludge...
I change my oil every 3000 miles... not sure what happened... I am guilty of using a cheap oil filter... I am considering upgrading the filter because of this.....
maybe HAMP oil filters????

How many miles on the car?

 

Where exactly is this VTEC screen?

 

Between the VTEC solenoid/valve assembly and the cylinder head.
