Only use the CC Cleaner if you've still got bad pinging after changing out the gasket.

 

I had the same problem, loosing to much oil to be just a leak. Reading this forum had me convinced it was the plenum gasket. In January I tore the engine down to replace the timing chain and front seal that was also leaking. There was about 3" of gasket blown out from the plenum plate. I never noticed any oil burning either but it had to be. I also didn't realize how long it'd been since I tuned the truck up, could barely get the plugs out. When I did, all of them had wet oil and carbon build up on them. I took a few shots of the intake before and after cleaning it up. I also snugged down the valvecover bolts. Some of them were pretty loose. Jeff.

 

Pictures didn't upload last post. Here they are. You can see how much oil was in the plenum. Jeff.
