Hello. I have a 98 Accord 2.3L and I think I have a problem with my Vtec Solenoid.
I get in my friends Civic and I can hear the Engine sound different at a higher RPM and her says that is Vtec.
That has never happened with my car. So I was looking around and people say they suggest taking off the VTec Solenoid and cleaning it with Brake Cleaner. replace the gaskets as well. So my question is: Is there a way to test my Vtec Solenoid? Before I take off the Solenoid do I have to drain the motor from Engine Oil? The solenoid is right next to the block so I am worried that if I take it off all the oil will come out. Any Help Please?

 

You don't have to drain engine oil to remove VTEC solenoid. Oil only flows under pressure when engine is running. You may lose a tiny amount. If solenoid were not working, an engine code would be set. It could be blocked, but this seems unlikely.

good luck

 

If that's a civic Si (DOHC engine) then her vtec is a lot different than an Accord's vtec. Yours is a lot more subtle, & switches at lower RPM too. Some B16 (civic si) engines have 2-stage intake manifolds and when the secondaries open up all the kiddies think THAT is the vtec sound.
