I don't think so. I've had it on and off several times, varying my tightening sequence and torque. One time it didn't start leaking until 20-21psi. So I think it can work, if everything is perfectly aligned and tightened.That flange design is a bit strange. I wonder it was meant to flex and leak above a certain pressure.
And that's where we are right now. As much as I don't like sealant, this would be the simplest solution if it works.Basic Silicone RTV or the 6000 series GOOP clear sealant. Just add a small bead as suggested above. It won't make an unbreakable seal but will get rid of your leak until you break the seal. Even slathering the oring with some higher temp grease like Krytox might condition what you have to make a seal again. I highly doubt they got any treatment at all and were just thrown in dry.
Hopefully that restored some faith in RTV. I had been in the auto tech industry for over 40 years, and RTV, with judicious use, has solved many sealing problems. Heck, form all the water pump failure posts on this forum, seems that RTV was the only thing used in the factory. Failed experiment? Misapplication? In the 1980's we installed many valve cover gaskets on GM products that came from the factory with only RTV. The main reason for RTV failure is due to improperly prepared surfaces...they need to be spotlessly clean and free of any contaminants such as oil, grease. And of course, just "a dab will do you". I've seen many engine failures due to too much RTV on the oil pan to block surfaces. The stuff just squeezes out, migrates into the oil pan, and blocks the oil pump pick up. I hope you cured your issue...pun intended...and save your pennies the the EC intercooler.24 hour cure was up this morning. Checked that the nuts were snugged up, and tested the system.
I heard it just start to leak at about 24psi, fell off pretty quick to 20-21psi, and good from there. (slow drop).
At this point I am calling it good enough...Unless the test drive tells me something different.
I may revisit it later. (And I will start saving for the EC IC.... )
No problem with RTV here, when used as designed. We used a bunch of the stuff in the industrial control industry, also. And put together enough motorcycle cases to trust it.Hopefully that restored some faith in RTV.
Is this a common issue and at how many miles can one expect this to happen?
This....From the start I reckon. Its basically by the way the flange is bolted.
But it's fine for stock tune as the turbo will make up for lost boost to a point.
The LensPen was a promotional giveaway, for entering a video contest. But the taper on the end was perfect, unlike your butt plug.Thinking about what to use to plug the hose with the green clip (actually look at WTF is a LensPen and how much it cost...) then remembered I have a 3D printer...
Did some crude measurements, jumped into an online free CAD software and a few hours later, voila!
Worst case scenario, it doesn't work on the 124 and I've made myself a weird but plug... That's a Win-Win in my book! 😀
