P033 code. Time for starter, knock sensor, valve covers, and? maintenance 2008 V8 SE

[randy88fj62]

Threw a P033 code yesterday. My scangauge is telling me it's a knock sensor? I'll be borrowing a borescope after work to check for critters and broken wiring. If the knock sensor is indeed bad then I plan on replacing them both.

While I am in there I was looking at the starter and the valve cover gaskets since they are leaking oil.

Here's my list so far, what else would you do? Is a new air injection pump worth dropping in? Very pricey.

intake gasket 1 of 2 2810050101
intake gasket 2 of 2 1717150030
air switching valve assy? 2572050011
air pump assy? 176100C010
passenger valve cover 1121350031
driver's valve cover 1121450011
QTY 2! Knock sensor 8961520090
starter 2810050101

I have a 2008 sport editon 4.7 liter V8 with 513,000 miles for reference.

You listed the valve cover gaskets, I would also get the spark plug tubes gaskets as well.

On the air pump, me personally @ $400+ I would do the bypass instead, or go aftermarket for $50+/-, but then you risk using a lesser quality part instead of OEM, but apparently the OEM part lacks durability at least some of them do, so that's why I would go with the bypass instead.

Thank you for listing the spark plug tube gaskets. I forgot about those.
