Default Re: 95 ZR1 Oil Leak Question

My leaks are coming from the fuel injector plenum to head interface. For some reason it seems all these screws/bolts are prone to loosening. I checked one I could get to and it was finger tight. My cam cover bolts were also loose. The previous owner had some work done. Two the the new header bolts had actually backed out about 1/4". The problem is many of these bolts either cant be properly torqued to begin with or can't be re-torqued after assembly like the injector housing bolts. I purchased a gasket kit from Jerry's and am planning on replacing the intake plenum and housing gaskets.

Funny thing is when I drive it it doesn't really leak because the intake should be in a vacuum, when I park it and let it sit, the oil accumulates in those spaces. That tells me I may have some very loose bolts for the oil just to flow out like that not under pressure. Like I said, I found one that was finger tight. When I get there and find the bolts are really loose, I may just re torque them and just replace the upper intake gaskets. The upper plenum looks easy to remove but the lower FI housing looks like it could be a pain with the injector assembly etc. Let me know how it goes.
