SELONOID, wow it took meeh forever to learn to spell that word correctlly in english.LOl Wow sounds like a tricky one there. The selonoid might be stuck closed, as for not open becuase yu would certainlly be able to tell.Being yu bent valves means that yur car jumped timing in order to do so even if it was a little degrees it jumped it enough to run the pistons into the valves at an undesired point.There can be many many reasons, one far fetched one that happened to us here at DUNK Performance and Tuning-Thailand:We had a 99 HOnda Prelude SiR. My cousin missed a shift and slightlly over reved. He did not bend valves but blow a head gasket.All spewing everywhere, wut a mess. Afyer full repair we did not seem to notice the VTEC punch or tone frum the intake non the less the exhaust system. The solenoid was fine but turned out the pump was not pumping enough pressure above 3500 RPM. It pumped enough to keep the nottom end lubed and i guess the top end also but not supplying enough oil pressure in VTEC range to activate the secondarry lobes on the cams via the solenoid. This is a long shot but may not be yur case. After we replaced the pump the VTEC werked flawlessly. Inspection of the old pump turned that the jolt it took frum blowing the gasket is wut done it. One more instance was on a 95 Accord R where it did bend valves. The oil delivery was there and everything okies. turned out to be the solenoid was not operating properlly. Could be to the Engine being in VTEC range when the damage was done to the valves, thus for jolting the solenoid and rendering its operation. One way to check the solenoid is either on car or off, which off is better, jump the leads(if on car unplug wire frum PCM to the solenoid first!!) jump it to a power source, one side to a positive and other to a negative touch it on /off/on / off, yu should hear and feel a clicking from the selenoid...Test 2 Oil on demand? with the solenoid on the car and the solenoid unplugged, with the same jumper leads in hand, one to positive and one to negative, start the car, have a friend raise the RPM to 200 or 2200 RPM jump the solenoid on off at 2 sec intervals yu should hear a diff in the engine. It should slightlly bogg or make a slightlly throathy intake sound and run slightlly rough while engaged. BE CAREFUL!! I have done these procedures in the past and the have been useful.


sorry SOOOO long post
