isn't a 997 just connecting PC and program out faults ?

Yep, unless you've got a problem that the readings from different instruments point to.

After 2 30 minute drives with boost pulls last night, including sitting in traffic for 5 of those minutes, there is no oil under the car or on the oil pan - had to be the junction of the dipstick extension that was allowing it to blow out there and spray the motor.

I still feel a stumble or miss though, so not sure I'm home free yet on the all the cylinders firing correctly yet though. Car ran better before I was sitting in the stop and go traffic then seemed less happy. Does that scenario point us in a specific direction. Sitting at idle, are plugs more likely to foul? I'm using a BR7ES which is probably as hot a plug as I want to go with the supercharger setup, but open to options and opinions.

The next thing might be to run the SeaFoam then change the oil.

If the engine is still running with those oddly colored spark plugs - that's what you have to focus on. Put the SeaFoam in and put some miles on it. Go enjoy the fall colors.

Come back and ready your plugs.

Ha, this year is crazy. It's sill 90 degrees down here - no fall colors yet.

How long should I run the SeaFoam? I've seen where it frees up so much accumulated sludge where it can clog up the oil filter so I don't want to run it longer than prudent, but long enough for it to potentially have some benefit. Is this 50 miles, 100 miles, etc and do I need to drive it differently while that's in there?

Wipe your dipstick on a white towel before you go.
Drive normally.
Wipe your dipstick on the same white towel after 50 miles. If not sludgy - keep going.
If sludgy - change the oil and filter, add Sea Foam, and do it again.

Repeat as needed until the oil comes clean. It will darken, that is to be expected. But it should be clean.

More advanced: buy a oil filter cutter and lay your filter media out and inspect it.

Or send a sample off the Blackstone Labs to see what's going on

I cut open all my filters and send a sample at every oil change to Blackstone so I'll do that.

Since going back to the OEM dipstick solved my oil leak issue, I needed a way to better access the dipstick with the supercharger and blow off valve installed.

Bought a 90 degree hose and moved it out of the way a bit. Now I can reach in through the gap to the left of it and get to the dipstick. Still going to be tight when things are hot, but should be fine.

Gave me a chance to use my cool Redstack Silicone Hose Cutter tool again too. Let me take off as little as an 1/4" per cut nice and straight until I got the fit just right.

Original configuration




90 degree hose relocating the BOV




Clearance from SC pulley. The filter is actually below the pulley so there's more clearance than looks like in this photo.

Pete,

I know how crowded the 16v kits get behind the radiator. Here are two dipstick solutions for 16v motors with our supercharger kits on them.

1) Instead of extending the dipstick tube, we ship dipsticks with extended handles with our supercharger kits. Let me know if you want one of these?
2) gently bend the dipstick tube so the dipstick comes out into a clearing. It doesn't take much. See the YELLOW install below for an example of that with the OEM dipstick.

Thanks Carl. Sure, I'll take one of those longer handle dipsticks. That should help.

Hi Carl, and Pete. I tried a dipstick with extended handle and it helps. However, I still found it difficult to see the end of the dipstick tube, so I could put it back in. That's why I went with extended handle and tube. I got it on Amazon, but can't find it right now. It was orange plastic, so I can see the opening.
Good luck,
Dave

Dave, that's exactly what I had, but the junction where the metal OEM tube mated to the plastic extension piece, even though I sealed it with an inverted grommet and put a clamp on it to hold all that together tight, that's definitely where my oil was blowing out from and why it was shooting back toward that side of the oil pan, making me think my SOPG was leaking, which it actually isn't.

You can see it from the top and bottom in these photos. Handy, but caused me an issue. With my relocated blow off valve I'll have good access to the extended handle dipstick Carl is sending to me.

May i ask what that orange connection is for ? I assume it connects both heads ?
On my engines those are plugged.

A couple tips if you are going to bend your dipstick tube so that its easier to get at:

TIP: I have only taken my hands and applied the pressure to the broadest section of tube possible and bent them a little. You want to avoid kinks, obviously. I dont bend them a lot, haven't found that to be necessary.

BUT - if you are going to do more, locate a spring that is long and thin enough to slide inside the dipstick tube, like the springs we used to see on screen doors. Put the spring in the tube before bending it. OR: remove the dipstick tube from the car and put a spring around the outside of the tube before reshaping it.

Bend over the tip of the dipstick so there is a ball at the end and the dipstick will go in and out of the tube much easier.
