Boost Leak from BMS charge pipe.

billowusu · 10-17-2020, 08:07 PM

Did a boost leak test and realized I'm leaking boost from the charge pipe connecting to the tb. Anything above mhd stage 1 throws the car into limp mode. I'm running the oem charge pipe gasket. Any recommendations? Thanks for looking!

Check the O-ring.

Replace the O-Ring? Just a thought.

Yea, I did check the o ring. It looks ok. No rips. Double checked the placement. Still leaks boost.

I guess I'll try that. I might just change the entire charge pipe to the ones with the silicone hoses with clamps. Or if I could get a silicone hose to fit over the connections. What charge pipe are you running? How much boost are you making?

My vrsf chargepipe connects the same way without any issues. Id contact bms and see if they have any ideas
I’m running 20psi btw

BMS can send you a beefier ORING if you ask, they have them on their site.

I just looked on their site and it doesn't mention that they are bigger just heavy duty.....

Replacing the O-ring should fix this issue

Does the pipe move any if you try to wiggle it?

The TB stays in place but the charge pipe itself moves a tiny bit even with the c clamp on . No snug fit whatsoever. I just ordered a new o ring. I should get it Wednesday God willingly. I'll keep you updated!

Thankfully, the new o ring does work. Car pulls real hard! No more boost leaks ! Thanks again everyone!

I ended up getting it from boost monkeys mostly because of shipping time and cost. BMS would take almost a week to deliver. I saw some good reviews with this o ring working with BMS charge pipes.

This might sound a little weird, but I've heard of people having issues installing charge pipes over this o-ring. Struggling with it can possibly damage or stretch it.

Typically, if you freeze an o-ring then apply a thin amount of pet (vaseline) to it right before install, it can make installation easier. The smoother the install, the less chance of damage.

Freezing the o-ring will shrink it which limits interference during install. You just have to be gentle with it while putting around the TB.

I did put some Vaseline on mine this time around 😭

Vaseline help's in various places....lol

In aviation maintenance we use a similar item called 'Pet' (petroleum) but I don't recommend cross functional use with the aviation grade stuff.
