Yea I sprayed that whole area really good with soapy water when I took the intercooler off and tested the through the throttle body. I am ordering new injector seals and when I put them in I’ll double check all hoses and connections with great detail to verify none are cracked or leaking.
Yes definitely appreciate everyone’s help on here!! I am very mechanically inclined but all the help and suggestions have been great!!
I bench tested the BPV. I used a syringe in the small nipple while blocking off the bottom I was able to actuate the plunger up while sucking the syringe out...
Agreed on the compressor and that there still may be a leak. Tonight, I am going to try and bench test the BPV by connecting a syringe to the nipple port and using a block off plate on the bottom of it. If I try and push air into the nipple and it bleeds around the diaphragm and out the recirc...
Yes, I agree I need to do a compression test on it this weekend. It does not have any DTC and it drives really well, idles fine and comes on boost nice in the higher gears but stops building boost around 10psi. With the JBR intake I put on it I can't tell if i am hearing induction and turbo...
Yes sorry I forgot about that, I did replace the spark plugs when I bought it. That would make sense that the injector seals are leaking though because they are leaking on the cold side of the lines I’ve tested, which had the worst results. Unknown service history on this car when I bought it at...
Alright Im really lost now. I bought some pvc plugs and did more testing tonight. The intercooler is not leaking. I blocked one side and the BPV return and nipple and it holds tight.
I put the tester on the hot side and it kept blowing the plug out the intake tube at like 10-15psi so I’m...
I was worried about putting too much pressure in the motor and blowing out seals going that high, but I will try it, if it's safe. The other problem is I'm using a cordless compressor so it may not have enough CFM to get the PSI up quickly. It stalls at 13PSI and just sits there running...
If that is the leak on mine wouldn't the car run really rough? I am seeing -21psi vacuum on my gauge, which I've read is normal. The car idles really well.
I soaked down everywhere I could lol. I tried to spray under the top mount in that intake manifold area but it’s tough with the top mount in the way. Next step may be to remove the top mount and plug the hoses to see better what’s leaking.

Hey guys I’m new here. I just got a ms6 a few months ago and I need help with a low boost issue. I recently got a boost gauge installed and realized I’m only hitting like 11 psi in 5th and 6th gear. I have no boost in 1st...
