FMIC cold side Plumbing keeps popping off!

4doorbmwpower · 12-15-2012, 06:25 PM

Just had a boost leak about 2 weeks ago, found the source; it was the FMIC cold side plumbing omw home from about 75 mile drive (not even spirited driving) i lost a ton of boost again get home check it out and looks like the cold side coupler has popped down again. got a 1 inch longer one to hopefully illiviate this problem, anyone have any insight?

Easy Fix. Make sure the tube/hose is free of oil use a T-clamp as u can tight them more than the regular clamp.

before you do that, use hairspray; it works very well.

Hey

Didn't know you were still around. What are you driving nowadays?

I had the same issue for the longest time until I found out the problem. For me, the problem was the clamp I was using. For whatever reasons, it didnt like the clamps it came with my fmic. I used this kind instead: http://www.directindustry.com/prod/i...22-574313.html, and never had the same issue.

Check the silicone hose. Dry it & the piping it's connecting with. Then try and more intense t-clamp and tighten it down.

Thanks everyone im gonna get in there with a brand new longer coupler and make sure it gets over those rolled edges and dry it all out we all know oil lives in those pipes.. just dont have time to do anything these days!

Use hairspray or a little bit of silicone. Either will eliminate the problem.

Yeah. I drive a CRV around town.

After my wedding I'm getting a 335IS if Vargas turbo upgrade stage 3 is out then but if not may be a GTR it all depends.
How's ur car running?

Properly seating the clamp just after the bead is crucial to preventing boost leaks. Using t-bolts vs worm gear clamps will also prevent blow offs as well as keeping the alignment of the clamp straight when tightening the clamp.

or friction tape the endings and then clamp, but +1 on the hairspray.

That's why I have an HPF intercooler, uses factory clamps and haven't had an issue yet. Spike 17lbs on the daily and nothing. Hope you get your issue fixed.

I put a new longer coupler on today seemed to fix the problem, how would you use hairspray for this?
