I had a valve job done on my 98 Honda Civic GX
- Valve 4 had low compression on the tests but the rest of the valves were fine. Also replaced timing belt, air filter
, spark plugs, Cap and Rotor, VC gasket, head gasket
, O ring for #4, Oil pan gasket and injector. I had not been more than 5 miles from the repair shop when the Engine light came on. I went back to the shop that moment and he did a reading and told me it was Catalytic Converter
reading. He told me that CNG vehicles run dry and that moisture must have gotten into the engine when he had it open and that in 500 miles it would go away. He assured me of this and I drove away. About 300 miles later, driving with the engine light on, I was driving up hill to my house with the AC on and noticed that I had low power. I turned off the AC and as I pulled into my driveway I heard a sound (like a knock) and the engine light started blinking. The two trouble codes that come up now are P0420 and P0301. So my questions/concerns are this...
Is it possible that the Valve 1 failure is linked to the work that was done on the engine, if something was done wrong or aftermarket parts were used?
Could driving around with Catalyic Convertor problems cause Valve 1 to fail?
I spent almost $3,000 to get all of this work done and I don't have another penny to put into the car. The work I had done is under warranty so if more work needs to be done I need it to be covered by the warranty.
