Leaky Cam Covers?
anyone have this problem?
I was under the car looking for soemhting and noticed the cam covers are damp/ wet along the seam surface to the heads.. Reading Jeffvette's R&R procedrures on PNWZR1 makes it look easy.. but any specific Assembly lube? Also where can the the A136 sealant be gotten? Looks Like I will be able to refinish the cam covers this year after all

Re: Leaky Cam Covers?
It might be well to make sure it's not the center stud in the exhaust manifold leaking before you you tear into a tougher fix. Cam covers seldom leak but a bunch of exhaust studs do when the seal gives up.

I have almost everything out of the way except the brake booster.. then the cam cover should be not too bad to remove, assuming all the bolts move..

Re: Leaky Cam Covers?
I am also doing headers this spring and really need to repaint the cam covers so may as well do it now

Re: Leaky Cam Covers?
Its not the cam position sensor is it....or maybe exhaust bolts are loose?
