2002 Honda CRV variable timng electric control valve

Hello Yong Well, I am sorry to hear of your problems. I have attached a pic showing that the oil does travel through the valve. I would certainly think though you would see oil on the ground or if you were burning oil, blue smoke out the tail. There has to be some evidence of the oil going somewhere. I don't think not changing the oil for 180 miles though is the problem. I have attached a service bulletin showing that there was a problem with the valves sticking. It had nothing to do with not changing the oil. I have also attached a TSB concerning the pressure switch. Last, looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you. I hope this helps in some way
