Recently replaced the vtec solenoid gaskets and in the process removed the water inlet housing and replaced the gasket and o ring on that. Bled coolant. Oil leak which prompted repair seems resolved but now I'm getting a squeal at about 2500 rpm, starting and stopping while driving. Wasn't present before.

Did I mess something up Getting to those gaskets. Help? Ideas? Honda 2.2 vtec 4 cylinder 1995.
