i was getting air from my pcv as well. i would guess if there is blowby, it would be due to a cold engine not sealing perfectly moreso than just toasted rings.

can you hear air going through the open valves in the motor? I'm pushing about 22psi accordin to the gauge through my line but then i built a gauge into the tester as well and only create about 12psi in the entire system when the aic and pcv is capped.

To block off extra hoses, I know someone that puts bolts into the hoses that go to items that may leak. Like the a/c idle control, he blocks off by pulling the hoses to it, inserting appropriate size bolts, and uses a hose clamp to seal it in...

i bought this elbow shaped one instead, it makes it a little easier when going through this. its about $3 dollars more than the short straight one but i still put this together for under 20 bucks at lowes. i think my plug came straight from heaven, shines like that in the dark too...

The guy that pressure tested my car way back when had one with about a 3' pipe section after the elbow so the gauge and nozzle was out of the engine bay. It's hard to explain, but his was the best...but a little bulky...

It ended up being the exact same size as the inlet lol...Has anyone found a 2.5 piping at either Home Depot or Lowes? I went to both and all they had were
1, 1 1/2, 2, 3 & 4inches....

I've been looking for a way to efficiently find my boost leak, this seems to be the best way without a smoke machine.

Thank you!!!

leak at MBC?

Should there be a leak at the MBC? I turned on the compressor and air was coming out of the mbc. I was doing some searches and that the mbc should be leaking air?

I have one of the screw type mbc's.

Thanks!

I found the same thing happened on my Twos R Us MBC. It leaks out of that little hole on top, roght? I found that changing the knob's position can make it stop (forgot whether CW or CCW). My guess is that if you're using way more pressure than needed to open the wastegate, the ball in the MBC will compress the MBC spring far enough for the air to reach the channel connected to that hole, so air leaks out. It would make sense that if you turn the knob CW and increase pressure on the spring, it will keep the ball from compressing the spring as much, thus not reaching the relief channel, or whatever it is. It might be built in to keep the MBC from exploding with a crapload of boost. Just guessing...

This is what I came up with for the CT26. A bit on the expensive side, but I can regulate and monitor the air!

Leaking EGR

This is what the test revealed. Should I buy this new or try to find one used?

So... I have fixed two leaks, the turbo fitting 'Barb to Brits..' and the EGR with plates. I am still leaking a ton of air somewhere... There is a loud air noise coming from around the intake manifold... Any ideas? The sound is coming from under the EGR.

I do not think its the BPV or wastegate, but I could be wrong.

Common things to check in this area? I have heard the fuel rail can leak. How do i test that? I am a newb, but capabile of working down the list... I also have a BGB that I can look at, just need a push.
