I Have a beast leak and yet to find it. Just curious to what the common areas to look are.

I Have a beast leak and yet to find it. Just curious to what the common areas to look are.

bov flange, throttle body. pretty much anywhere, were there is gaskets or silicon cuplers.

anywhere gotta fix them all.

 

[Bud92gsx]

Like said any couplers or clamps, check the tightness of the clamp..Common mistake is not tightening the clamps enough..

Intercooler necks are known to corrode. Look for pinholes.

 

[Rex2342]

BOV flange
J-pipe gasket
Throttle body shaft seals
Lower injector seals
Intake manifold gaskets
Intercooler pipes/couplers
The intercooler itself

Those are the most common places for boost leaks that I've come across.

Taking a look at it this weekend.(dont have much time in the week). Probably buying a boost tester from Boostpro.net : Products - Boost Leak Testers . Going to troubleshoot and let you guys know where and if i find it.

Sometimes there a pain to find but spray all of the areas that people told you about with soapy water and see if it bubbles up.

Common places would be:
TB gaskets
BISS Screw
TB Shaft Seals
turbo outlet gasket
Boost reference source
injector seals
loose clamp on coupler
leaking BOV (2g stock BOV is notorious for leaking)
Intake manifold gasket
anything that uses vacuum off the manifold could be leaking air out

Make sure when you do the test you intake vavles are closed, take a look at this link:

It is important to do the test correctly, 40* BTDC, that way you can get an accurate result.

People always forget, back in the day, and some of us still use it, a smoke machine. Fill the entire charged air system and see where the smoke is leaking from. Its a lot easier thank using soapy water and tracking the leak down.

Also another side note, if you are using aluminum piping, be careful not to over tighten the t-bolt clamps, you can crush the pipe easily. By trying to seal a boost leak you can create one.

Try LICP (lower intercooler pipe), j pipe and try tighting down your t clamps

Do you have a stock side mount with stock piping or aftermarket piping or intercooler?

 

[Eclips3gst]

aftermarket turbo, stock intercooler, stock bov, and stock piping. putting pictures up in the next 24hours

i know people have said it but it seams like my lower inj seals leak the most even when i change them so i saw lower inj seals are very common, and intake manifold gasket esp with an older car with stock gaskets
