Boost leak

Ok cool I'll have to hunt it down some more. Seems like boost is normal until car warms up more. Then won't go past 4psi

Wastegate seals (orange ones)
Turbo piping - clamps
Turbo piping - cracks, especially on the underside which is not seen but discovered by "feeling" it out, has accumulation of oil/grease/dirt if so
Unsecured control hoses atop the intake manifold as referred to earlier
Dirty MAP sensor(s) / connector(s)

Gotta get this sorted ASAP. Thought maybe turbo was going bad. Trying out a new tuning device soon want it all right first. Is this the benefit of going to hard hot pipes? Less chance of this? Lol

At least it will get rid of boost leaks from those pipes, yes.

Right on. The hunt is on for a leak. Must expand when gets hot causing lost boost?

Anyone have the part number for the factory BOV? Just trying to price out in case

I think Z has posted this a few times before? It's called the air duct valve, yeah, not what we expect it to be listed as, LOL.

Checked all my lines and connections. Everything seems solid. Looks like the BOV are releasing some oily residue. Is this normal?

No Bueno! Hows the back/rear BOV!
Check your CAC (Intercooler) with an oil dipstick while the Drivers side is jacked up. Z

Is that the BOV doing it or the pipe it's attached to is leaking?

Both look this way and it's oily greasy in the direction they discharge also. I'm really unfamiliar with turbo cars so sorry for the questions. But would this be oil coming from the turbos?

Oil is probably coming from build up inside Intercooler, but it does come from the turbos initially.
Best route is to clean it out (suction/vacuum pump)
and use a high quality synthetic oil and possibly think about a catch can.

I have a catch can been meaning to install. Guess this just means needs done ASAP. Also I was always told to use ford motorcraft that is was best for these cars. That not the case? I've always ran Mobil 1 full synthetic in past vehicles and had great results. Could this be signs of a turbo failing?

Install is ASAP. I run Mobil 1 in my car. You can get it dirt cheap at Walmart.
