Hi all,
Running completely stock setup beside exhaust pipe. Been trying to diagnose and getting very frustrated. Last night, I was driving my car and I suddenly started hearing a loud clacking sound from the engine. Pulled over and checked inside. It seemed to be coming from near the cam gears, but I couldn’t pinpoint it. As I drove, it continued and increased/decreased respective of RPMs. Then I heard a whirring sound for a second before the clacking continued. Almost home and was accelerating and the car stalled. Tried to start it and it would crank, but no start after that stall.
I checked the timing belt, but it seems snug. Did a compression test and found that each cylinder was somewhere in the neighborhood of 40-70 psi. However, the gauge I used was kind of old, so I’m wondering if it’s really accurate (even though it’s a simple device).
Performed a spark test and found that none of my spark plugs are creating a spark. I verified my equipment was not faulty by trying on a vehicle that is working. This made me think maybe it’s a bad coil, or the ECU failed. Checked the ECU and it looks fine.
Could it be the coil pack? What is the chance of both packs failing? Or does it fail as a unit? Still doesn’t explain the low compression, unless the equipment I used was too old to work properly.
The picture attached shows the timing belt. I’m afraid maybe I jumped timing? But again, that doesn’t explain the coil pack. When cranking the engine, I don’t hear any sound of valves hitting, so I’m at a loss.
Any help would be greatly appreciated...
