While changing my thermostat temp sensor I saw my intake valves were quite dirty. At 130K Mike’s it’s unlikely they had ever been touched. I made my contraption and walnut blasted them clean. As a preventative measure I added a Mishimoto oil catch can.

Here is some pics. Waiting on shrink tubing to finish.

If there’s any interest I’ll post more details. I did post all other work on Rennlist.
