VALVE COVERS
So next at bat was the value covers, based on some of the oil on the engine, it made sense to change the gaskets. My plan was to sand down the covers to “unwarp” them and put back on. Here is what they looked like before, you can see the oil in the tins for the upper, and everywhere on the lower.
I took off the valve covers, they are both the original magnesium, they definitely had a little warp in them. I put the covers on my granite countertops. In the video below you can see the warp.

I brought them to a machine shop. A number of machine shops could not work on them because they were smaller than their machine would allow. When I finally found a couple that could do it, the prices were over $200 for the 4. Given a new set is not much more than that. I decided to purchase new turbo covers, but try to fix the upper ones myself.
I put sand paper on the counter then sanded the cover. It took a little time but eventually got them both nice and straight.
Then a good cleaning while the wife was out.
Once complete, I installed them with new gaskets and new bolts. I torque them down to 8nm. Surprisingly light tightening, but who I am to disagree. I really don’t think I needed the new bolts, but they came with the gasket kit. Here is the final product. Looking good.
Next at bat, all those frigging vacuum lines!
