Hi again and thanks to everyone again.
I now have a possible serious engine killing situation going on
. I'll explain exactly what happened:
I bought a tranny cooler on amigo-2k's advice and also picked up another can of sea foam. I haven't installed the cooler yet but I did take the grill off to check for proper placement, Anyway, before yesterday I haven't put any seafoam in the crankcase but decided to do it thursday night, drive on it a day or two and change the oil on the weekend. I put about 1/2 of the pint into the crankcase then let it idle for about 10-15 minutes with no problems. Then I decided to put the other half of the can through the intake to really clean it out some more before I put the new plugs in it. I put it in the first time through the pvc valve that's on the front of the intake so this time I put it in the brake booster line on the back in an effort to clean all parts equally. When I pulled the brake booster line off of the engine side it immediatly died, so i poured about 2 ounces with the engine off. It started back up fine with normal seafoam white smoke so I thought no problem. Then I poured the rest of the can into the intake through the brake booster line with the engine off and let it sit fo 15-20 minutes to get a good soak. Whithin 3-4 seconds after starting the engine, it started knocking. not a light tapping but a knock so loud it's allmost deafening standing over the engine and can probably be heard 5 blocks away. After a quick shutdown, I did a check for anything obvious like a broken belt, something caught or unplugged. Everything looks normal. I did a quick web search and thought it might just be a carbon knock. Others have said that a bad one could sound like broken rod. Is this true? Then I just let the engine Idle for about 3 minutes hoping if it was carbon it would burn it up and quiet down but it never happened. I unplugged each of the coil packs one at a time just see if I could isolate it that way but there was no change with any plug disabled. This morning I took all the plugs out and they were all black with the exception of #6 that was covered in either oil or wet black carbon(hard to tell). I cleaned each plug with carb cleaner and since I'm still waiting on the new plugs I just sanded the plug tips with 220 grit sandpaper. I cleaned the boots since they were pretty nasty too. With the plugs out, I turned the engine with the starter to try and clean out anything if it's possible that way. Four times about 15 seconds at a time. I put it all back together but it sounded exactly the same so I slowly poured about a pint of warm water into the intake. That produced more white smoke than sea foam ever did. It's still sounds like a major problem like I threw a rod but if that's the case how? I didn't really do anything I haven't done before except put seafoam in the crankcase.
. At this point I'm completly bummed about this with no idea what's wrong or how to fix it. The new plugs are supposed to arrive today and I plan on installing them tonight with a snow ball's hope
that anything will change. Has anyelse ever experienced this? What was the outcome?
Thanks,
Tony
