Hi, I opened up the plenum today of my 95 Blazer to start the process of replacing the intake manifold. There were a few small puddles of oil near a few of the injectors. Is this a concern? The motor does not burn no smoke and the vehicle runs fairly smooth. Any input would be appreciated..

Thanks,

I wouldn't worry about it unless the truck is burning a significant amount of oil. It's probably just getting pulled in through the PCV system which is constantly recycling crankcase vapors/oil mist. Could also be from slightly worn valve stem seals / guides....
