VARIABLE TIMNG ELECTRIC CONTROL VALVE

2002 Honda CRV

Engine Performance problem
2002 Honda CRV 4 cyl All Wheel Drive Automatic 100000 miles

Dear Sir,
I have a Honda CRV 2002. A few weeks ago I found check engine light on. I cleaned gas cover and the sign went away. Then, 4 days ago, while I was driving at a speed about 40 mph, the car started to choke (appeared as fuel line was cut several times within several seconds) and the check engine light came back on again. Today, I went to an auto mechanic shop and I was told that the engine oil was completely gone. I towed the vehicle to my regular service provider and I was told that the variable timing electric control valve failed then the engine oil leaked out and burned. The logic was that because my car is 180 miles overdue for next service therefore, the variable timing electric control valve was damaged, and then, the damaged value caused oil leak and burn. However, the car ran very well and I never smelled anything. I was not convinced by the provider (180 overdue for oil service damaged the valve). Can you tell me if the valve can cause the oil leak and burned outï¼?

Thanks

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……

Thanks for the donation
