A couple of loose Intake manifold bolts should I ?
Permalink  
 

I noticed a little oil on the intake, at first I thought it was from the carb; but now I think it may have been due to one or two loose intake manifold bolts.  Is this likely?  I re-torqued all the bolts to speciations.  I will have to drive the car for a few hundred miles and see if any improvement.

Would it also be a good idea to check the head bolts in the future?  As I am thinking it might be a good idea to replace the intake gaskets next winter and I could check the head bolts at that time.  Also there appears to be some grim of some sort coming from the intake-head-block corner where the assembly stamp is located.  I think it is coming from the corner where the three meet; but who knows what is the real cause.

Where those three planes meet is a common area for oil leakage; hopefully you fixed it by re-torquing the bolts.   Most guys squirt some silicone where those two gaskets come together during assembly.

Oil has a way of wicking up the bolts. I little blue locktite will prevent that from happening.
