Good old oil sensor replacement. The FAST manifold does not leave any more room than stock to get in there, but figured if I was chasing down a leak I may as well pull everything anyways. Had a leak around the brake booster vacuum line going into the manifold but the manifold is dry as can be on the inside. No sign of leaking for the valley cover gasket. Only tell tale sign is the residue on the side of the sensor pedestal. The sensor is still reading fine, but it doesn't look like it was seated all the way, the washer wasn't seated and sealed.

Hey guys looking for some suggestions on valve/coil covers. I powder coated the stock ones, but because of the heat, I think I'm going to get some coil covers, as well as valve cover combo, besides Holley and Eddie Motorsports, any recs?

I think Coil covers are cheapy looking, i.e. Eddie Motorsports or Mr Gasket
