Yesterday after running the SUnbeam fora few minutes I noticed that it
was dumping out the wastegates port at idle. Since I have had some
issues with wastegates before I started isolating the problem. I found
it thankfully in only one of the gates. And fourtunately the easiest one
to remove. The diaphram that moves the valve open and closed has a small
hole in it. That releases the air from the bottom side to the top side
of the diaphram causing that one to be essentially stuck closed all the
time.. That same plumbing system controls the other unit as well.
So the removed the offensive unit and tore into it. The piston inside
has a sharpmetal edge that did the evil deed as the vlve opened and
closed. The real issue is that this is a chinese unit (yeah, I am a
cheap SOB, so get over it) and replacement parts are non existent. I
have ordered a couple more gates and they should be here in a week or so.
The question is, do any of you have any iideas on how to repair a red
silicone material or know of any items like high temp tape that would
work to plug this small hole? If the darned this was made of rubber like
a bicycle inner tube, I would just use a patch on it. But is a silicone
material and hardly anything really sticks to it. And this area gets
hot so it needs to be capable of around 500dF or so.
I just need suggestions or methods to repair this, so don't get crazy
and tell me I am a dumb sh*t for buying this junk to begin with, yada,
yada...
Anh helpful ideas out there?
mayf
