I pulled the engine today and found that the front plugs under the timing chain were in fact installed correctly-meaning they were all there and staked to prevent being pushed out. I pulled one of the plugs in the rear of the block and found that the too were corrct and without oil restrictors. I didn't have time to pull the oil pan to check the plug underneath the rear main cap-as the lady was on my ass. I'm almost afraid to look under there and find that it too was installed correctly. What else can I look for if I find that that plug is in there? Anyone have any other thoughts...
