Well, the old reliable ‘09 Accord with 230k miles is having an issue.

Went to the store just now and when I cranked it up, it just sounded different. Like a vibration/moan/droning sound. I gassed the engine a little, brought it up to about 1500rpm and let it settle. The battery light came on.

Grabbed the volt meter and measured 14v at the battery while running. Got back in the car and the light was off and the engine sounded fine. Ok, whatever.

Went to the store and when I got back in the car and cranked it up, the check engine light was on. WTF! Plugged in the reader and got P0430

Also noticed a loud tick coming from the engine now. I can’t isolate where it’s coming from.


Almost sounds like it’s under the intake.

Any thoughts?
 
For Cryin' out loud!!!

so, the Check engine light for the Cat went out, so either it's broke, or the problem healed itself. I'm gonna go with all fixed!

Then this morning, the battery light was on again for a couple of minutes. Makes me think that maybe the battery is on it's last legs and the Cold weather is bringing it down just enough to trigger the light.

Then on the way in this morning I swear I heard a rock or something hit the car somewhere, then at a stop light I see little bits of smoke coming up from the hood. quick glance at the temp gauge tells me that I'm running on the cold side, not the hot side (no numbers, just an idiot gauge with Cold, Normal and Hot. And it's below normal. See some more smoke, so I pull off to inspect. Engine is basically cold after having been on the road for 20 minutes. I can grab the rad hose and lay my hand on the engine. Then I see the smoke coming from unexpected regions. follow it down and seen green and steam bubbling from the AC Condenser. SON OF A BITCH! this is the second time I've caught a rock in the condenser on this car.

So I'm thinking not only do I have a hole in the condenser, but I have a failed Thermostat. Interestingly, I previously theorised on my Truck that a failed T-Stat lead to enriched mixture which led to Cat issues. Wondering if I have the same damn thing happening with the Honda. That's a crazy co-ink-y-dink if it is!

Anyone ever JB Welded a hole in their condenser before? I'm wondering how much pressure that system really builds up.
