Project GD Subaru STI, Building the Engine Part Five: Final Engine Assembly With IAG.

Assembly lube is applied to the cam caps.

The cams are dropped into the head.

Sealer is applied to the outer cam caps.

The cam caps are carefully run down in a cross pattern a bit at a time. Do this wrong and you can crack the cams.

The cam caps are torqued down.

Now sealer is applied to the top surfaces of the cam caps and the head.

  1. I assume for the AVCS oil feed lines, the factory style screens are not used right? I only thought about that because the style of banjo fittings used have the bump on top, which for Subaru means they put a filter in there.
    I’ve always wondered how dirty the inside of the cam covers get over time.

  2. When do we finally get to see this bad boy on the dyno? What intake, what turbo, what exhaust, what blow off valve, what header? This is 5 months old!
