Hey guys i got a tune yesterday and it was at 30psi. Boosted it all day. Then the last little pull i made it only saw 25 psi. I come home do a leak test and hear a pretty good size leak but i cant feel air or see any bubble with windex. It sounds like the air is inside the intake manifold or around it but all hoses are tight and everything. If it was the TB seals would the car bubble anywhere to indicate or is it a matter of buying them and changing to see?

 

checked pcv valve and iits good, the noise doesn't change with position of the throttle, i can't find a hose off and it sounds like it is behind the intake manifold. I recently deleted the EGR and capped and ziptied the two hoses going to it and they are still capped/ziptied, and the egr block off isn't leaking either.

 

If the car is an 05, its a good 98% chance they are leaking

 

For TB seals you will be able to hear and feel air escaping around the throttle plate spindle on the outside of the intake mani. Try water and dishwashing soap applied with a small brush and you'll see the bubbles if it is the TB seals. Just work your way methodically over the mani with the soapy water and you'll find it eventually.

 

i feel retarded haha the other end of the EGR hose wasn't zip tied to the solenoid. I have had the EGR end of it come off but now that it is capped and zip tied i guess the other end didn't like 30 psi lol sorry to waste you guys time. On the upside, the TB seals do not leak at all! once i ziptied that line i didn't hear a single peep out of the system. Thank you i was thinking it was gonna be a pain in the @$$
