Just wanted to share how I did my valve cover baffling on my 2007 s2k and also give a big thank you to RAIN H8R for coming up with this awesome mod! I chose slightly different locations for a few of my baffling holes:
As you can see, I did not remove the baffling when I drilled my holes. After drilling the holes, the first thing I did was use a deburring tool to deburr the backside of each hole. I then proceeded to flush out the valve cover religiously. First I rinsed with water and detergent, then performed another flush with hot water, then finally hit all the holes with compressed air and gave things a thorough drying. After each flush I also used a strong magnet around each of the holes to try and grab any lingering swarf. Anyways, just wanted to share my slightly different version of this mod!
If anyone is on the fence about this mod, just do it!
The smokescreen problem is a major issue at Harris Hill Raceway in San Marcos, TX which is the track I frequent the most. Specifically, it happens at Turn 10 which is a tight hairpin and happens with both AP1s and AP2s. Initially when I first started tracking three years ago, it was not an issue but as my skill level increased and I was taking the corner faster, I started to have the smokescreen, the car would lose power and I was burning almost a quart of oil for every two sessions. I told myself I could not keep running this track unless I solve the issue and get the valve cover mod done. Well two weeks ago, I sent Dustin my valve cover a week before my track day. I let him know that I was in a time crunch since was sending him the original valve cover as I did not have a spare to send him. He received the valve cover, performed the mod and had back in the mail within 2 days! That weekend, I was able to get the valve cover on and I made my track day at H2R a few days later. Smokescreen issue gone FTW! And I only burned 1/4 of a quart (if that) of oil through all 3 of the sessions which I would consider to be normal for a tracked car. I highly recommend this mod to anyone who tracks their car and dealing with Dustin was super easy.
Finally just did this after getting smoke screens in T3 and top of the upper esses at VIR. Like others, I just drilled without removing the baffle plate, used blind deburring tools, magnets, and lots of washing out.
My car is an AP1 - solved all smoke issues at the track this past weekend and my oil burn was significantly reduced - basically non-existent.
I had dustin (rain h8r) do mine. I haven’t done enough after testing but there’s definitely no/less smoke on track, still need to rig up a bracket to mount a catch can where I want to put it also

When you mention flushing with hot water are you putting it under the faucet or pouring water over it and into the holes?
