Makes sense now. You are not talking about #1 air pipe, but rather the pipe that goes from the intercooler, right driver side of the radiator, to the ETM (throttle body) on the passenger side #6. This pipe can be a bear to take off and reinstall as over time the plastic gets pretty firm. It can als...

I have solved the problem by applying a very light layer of RTV (letting it cure before installing) to the inside of the pipe where it mates to the intercooler and the intake. I installed it and it does not leak. I appreciate everyone's suggestions and am willing to hear any other ideas on how to so...

You have the 2.5T per your original post. The pictures posted by another member are for the 2.9. (I have been battling an overboost situation of my XC90 so the pictures were too familiar) I just did the pcv system on my brother's XC70 with the same 2.5T engine so it is fresh in my mind. The car has...

Buy a new pipe to engine inter-cooler hose and be done with it. The RTV over time will become loose and get sucked into the turbo - that connection hose is water logged with oil. They get soft over time due to the heat and oil. Examine your original hose clamps for signs of damage. If over-torqued ...

Within the last year my plastic portions of the intake and charge pipes had to be replaced due to leakage. The dealer simply put new parts on. It was the charge tubes that were leaking. I had no engine light or warnings that anything was wrong. After installing the new charge tubes the original cla...

I took my tube off and put a thin layer of RTV on the inner openings of the charge pipe in hopes of giving something to seal on, much like the suggestion of the silicone rescue tape. I like the idea of the silicone rescue tape better, but I have already put the RTV on and am waiting for it to cure b...

My mechanic at the dealer said the original clamps with the metal backing have trouble with age. June Likely the rigid hose starts getting stiff/brittle with age and the clamps can't exert enough force to squeeze the tube adequately to get a good seal before stripping out. If the hoses are nylon-pl...

This looks worth trying. Thank you.

Hello, I have a 2004 Volvo S80 2.5T. My lower plastic charge pipe leaks at both ends at the couplings. It seems the more I tighten the clamps, the more they leak. I am pressurizing the system with ~ 5 psi compressed air, and can hear and feel the leaks. Sometimes I can get the side which attaches to...
