Turbo BS Thread

Is ur pcv seeing boost?

 

Your pcv should be routed to a negative pressure zone like before the inlet of the turbo. It should also route through a catch can too but one step at a time! lol

 

It's in the original factory spot

 

Pull the pcv, check it still holds air

 

Yes it does but when I do the leak check and put air through the system back the other way like boost it leaks out mostly through there if I put my finger on the PCV valve it barely leaks at all through the whole system

 

Wastegate leaks a little

Ur welcome for the test tip

 

So the pcv sounds like its done. It should be able to hold 15psi per requirements of the stock engine. Although, the outlet should be run before the turbo inlet so you dont negate the flow OUT with boost pushing the valve closed.

Thats very minimal, should pose no issues.

Not the only one who repurposes condoms for testing purposes haha

 

Yeah i got the idea from that but thought as long as it doesnt melt it should work for exhaust too and it does.

 

Is it supposed to hold 15 psi no matter which direction or only vacuum

 

The valve should hold 15psi ENTERING the valve cover through the valve. It should allow all pressure inside the engine to escape without restriction.

 

Sounds like you need to just replace the valve. It probably pretty gummed up with that high of miles

 

The valve is new so I wounded what's going on with it

 

Here's what it looks like comes from the original spot off the intake and to the valve cover

 

Put a filter on the valve cover, and cap the intake.

 

https://youtu.be/YqJf6RWRWmA cant build boost (my wife is driving and she may have been taking it a little easy but still she said it was over half throttle)
I guess ill check all my clamps on my ic piping

 

What are you using for boost control?

 

A wastegate with a 7.5 spring...

 

seems like that may be way too light. I dont hear turbo spool at all in the video

 

I know it only barely got to 0 psi thats why i figured i had a leak on the cold side

 

That looks like how mine is as well. I used a valve from LCE that has a metal body. Idk what difference that makes but I haven't had any issues. I haven't leak tested it or anything but I haven't noticed any boost issues
