Re: some issues with my UrQ--MC engine (long)

Orin Eman decided to speak these words:

I will give this a shot, but i think that they already did this in 
another form.  I think that they ran that wire to a connector where you 
can plug in the light i described.  If i were to make the tester, i 
wouldnt need the instrument light...But i will ask the bennetts tomorrow 
and see if they can give me an idea.

Yeah, i took a look, one of the covers is loose, but it isnt the source 
of the noise.  I pushed it back and out of the way, but that did nothing 
for the noise.  It sounds most focused at the cam gear.  Almost internal, 
on the cam.  

>Injector seals?  If your fuel injectors are wobbly, it's the big

I checked all the injectors, they are in there very solidly, so i doubt 
that is the problem.  Plus i dont smell any gas there....

>Idle stabilizer or bad vacuum leak.  Perhaps one of your fuel injectors
>has popped out... would explain two symptoms.

I lean toward the idle stabilizer due to the other problem with the idle. 
 If it wre just a simple vacuum leak, it would be a self sealing one as 
the car warmed up slightly.

>Well, you _have_ had the turbo red hot, so maybe the EM has warped
>or come loose.  Might explain your wastegate complaints too.

Yeah, funny though, the wastegate noise started way before i got the 
turbo so hot.  But i got down in front of the engine while it was running 
and there is a definite puff of air coming out of there, so the manifold 
is leaking already...grrrr...and i have been really careful about cooling 
it down correctly...jeez...less than 1k miles and i warp the manifold...

im gonna post this to the main list just to help out a bit...

thanks for the input though, it gave me some stuff to check out
