Valve Cover Gaskets
I have oil seepage around the gaskets on my valve covers. I tried to tighten to the torque specs in my Haynes manual. What I have on an '85 are threaded studs that attach to the head and the covers are then held on with 4 small nuts. I am afraid if I torque them down I'll break them off. Also I don't know if the gaskets are correct. This must have been a problem for GM because it was changed in '86.
Has anyone experienced this and if so how did you remedy it?
Can I replace the studs with bolts? What is the correct gasket part number?Will I need to replace the valve covers?
I have to fix this because oil is getting on the exhaust manifolds and
man-o-man it STINKS! :confused: :mad :cuss

hi,buy yourself a good set of fel-pro gaskets for your vette and when you put them on put a thin coat of a good gasket silicone sealent.i always use a quarter inch drive ratchet and socket set to tighten those valve covers.tighten then down snug and with the quarter drive there is a less chance of you breaking the bolts.good luck greg84 :cool:

I understand the reason they went to a centerbolt design was because the side bolts werent applying equal presstre to the whole gasket. Use some of the blue RTV glue (the permatex that adheres especially to oil). That will help a little and keep the gasket in place during mounting.

I just replaced all on my ironhead '86. Get the FelPro Permadry gaskets. They use no sealant. Get a torque wrench to tighten the nuts to 100 inch lbs.
Make sure you check the torque on the nuts each week. Mine tend to loosen up. I want to apply locktite but am nervous about that.
