oh no, my issue is 32 PSI on a engine i overheated MANYaTIME and 230 HP with some sick temps. dont worry about why my AHU is a pile of parts right now! (hint: Im doin a 350HP+ build into a Porsche 944 with it!!!!)
Pushing out coolant is not a head gasket necessarily. the EGR can also do this.
My advice on the pop issue, get the tool to remove the glow plug, there is a very specific tool to remove this, do a search on it, there is also a tool to tap and fix it if it gets worse. Compression and leak down test are going to be CRITICAL to making sure you pop is not from a leaking valve. you might want to check your timing marks and make sure its spot on, also VCDS and check your timing advance. those 2 things could also be a possibility to a poping sound. are you sure its from the intake?
Mongler,
Woah! I was hoping to put a chip and bigger nozzles in mine, but you're obviously on a whole OTHER level with your cars! LOL!
To clarify --- if you do *not* have coolant pushing out of the globe, does that mean you do *not* have a head gasket breach? and/or EGR issue?
If that is the case, I can rule that out now! (fingers crossed)
since i *was* loosing coolant and saw some oily residue in the globe, i was trying to decipher if that was a head gasket (or egr).
The coolant leak was the o-ring in the coolant flange. appears to no longer be loosing coolant, though haven't driven much or pushed it hard this week.
The glow plug thread -
this had some terrible "repair" done to it already by po/or po's mechanic. it must have been stripped/cross threaded and then it was "fixed" by stacking TWO helicoils... like they didn't have one long enough so did two...? never seen that before. You can thread the glow plug in just fine through the first heli-coil, but then when it gets to the 2nd helicoil, the threads don't line up, so then as you seat the plug farther, you strip the threads on the GP. It will seat and seal though! But when you remove the GP, it is then rendered unusable because the lower threads are now stripped out on it, so no way to reinstall it.
compression was good on the 3 cylinders i could test.
i could do a leak down on those 3 also...
popping sound ---
I did the belt with all the proper ALH tools, double checked timing marks etc.
I have VCDS, just checked, timing graph is spot on.
motor overall runs well. no smoke. no cold start issues.
the popping isn't constant, which i figured would rule out the valves???
sometimes it pops a lot, other times it doesn't...
pretty sure, but I'll remove the intake again at the EGR valve
I just ordered a new globe from idparts, just to see if any new soot or oil appears..
