I know its been three months since I replied. Been busy with too many projects to bother with this sight. Anywho, was curious if you figured out your pinging problem? To fix a wrist pin problem is quite an extensive process. Tearing motor all the way down to remove pistons and replace pins and bushings, possibly pistons as well. In the short term, probally no problems, left unattended, think of your engines rods being the star of a slasher pic and carving someone up. The goop your seeing in the front of the engine is most likely a small coolant leak. The 3800's are notorious for leaking coolant from the intake bolts since the screw into coolant passages. There is no engine oil supplied to the S/C and no coolant passages at the front of the S/C to intake. So I would say it's just a case of needing to replace your LIM gaskets, just make sure you put some pipe sealant on the intake bolts on re-install. Something GM didnt do during assembly. If you've already got this info, sorry for the late answer. Good Luck, let me know!
