re-torque the bolts in the order found in your intake assy instructions. Check your oil for water which I doubt if ther will be any and run it again. Just be sure of the torque and tightening order.

If you check your oil & it's clear, then everything is good :) . It's when your oil has a milky color to it that you have water in your oil.
Be sure to have your car running and check to see if you can see where it's coming from.

Rick,
Can you determine whether the oil is coming from the valve cover or from the intake bolts? If it's coming through the bolt holes, then remove the bolts, clean them and the holes real good, and apply Permatex #2 sealant on the bolts and reinstall them.

Retorquing the bolts probably won't stop it from leaking but it's worth a try. You will most likely need sealer on the threads. Also be sure it's not coming from the ends of the manifold.

Hey Rick,
I used to have a leak through the intake bolt holes. Precisely those four bolts around the carburetor. The Permatex #2 treatment worked like a champ! I don't think retorquing the bolts would eliminate the problem for good...
As for it helping with the vacuum leak, I dunno.... I'm having the same sort of problem with my car.... Trying to diagnose the problem, yesterday I ran the engine with all the vacuum connections plugged--no deal, still running rough and lean. Retorqued the manifold bolts--little improvement. Then I sprayed starting fluid around the carb base, and found that the idle picks up when I spray on the rear/right corner. So I'm suspecting my problem is a bad gasket... Will replace it tomorrow, and see what happens. Sorry for rambling on--this is my "problem of the day"...
Good luck!

Rick, That same bolt leaks on my newly installed performer manifold, too! :yesnod: Must be something to do with how the oil is squirting around there. Lets both do the permatex #2 thing. Retorquing wont cure the leak. But if you haven't re-torqued since installation, you will need to do that too.

Re: Corvette Panic Attack..Please HELP! (JRChurch)
when you installed,did you make sure the heat risers in the heads(if you have them)were properly blocked off......if not,the heat from them can cause the intake to warp or crack....you need to check the mating surface with a straight edge to see......can then either machine or repair crack if that is what it is...that would explain the vacuum leak....not sure about the oil leak though.....john :chevy

Do yourself a BIG favor and get rid of the glass filter. We really don't want to read your post about how your car burnt up and took the house with it. Those things are nothing but dangerous.

Re: Corvette Panic Attack..Please HELP! (79MakoL82)
Because of the thermal expansion difference between steel and aluminum, it is a good habit to get into: re-torque the bolts after long runs or aleast every day for a couple of days after installation. I found that I had movement in the bolts for three days after I installed one on my engine. You should not use RTV on head bolts, permatex #2 is best. Just in case, Washers are needed on the head bolts when installing an aluminum manifold.

Rick,
Check out Lars' paper on how to build a cool fuel line using an 85 Vette filter, without using hazardous rubber hoses. You can download the paper from http://corvettefaq.com/
Hope this helps.....
