-Motor and transmission mounts...
Yep. I've replaced those before.
... I made the mistake of going with OE SACHS for replacements rather than bilsteins, the Sachs have a much too squishy feel, and not in a good classic-luxury-car-squishy kind of way. The Sachs still feel as though the car wofts around too much...
OK. Which Bilsteins did you go with? B4 or B6? I've read that B4 build quality isn't as good as Sach OE, but that B6 is much better. I'm looking for long life.
-Driveshaft center support and bearing. its not so much the bearing that goes bad (mine was fine with nearly half a million miles of wear), but the support that HOLDS the bearing that goes bad. if your transmission mount has ever allowed the trans and driveshaft to sag for any period of time, it wears out the rubber in the support and causes it to crack and break loose.
I'll have a close look at this soon.
-Check ALL your ball joints and rubber suspension mounts. you would be amazed how much super tight suspension improves ride quality and handling. check the rubber bushings super closely, any cracking is a sign that excessive movement is taking place in that bushing, and it needs to be replaced.
I do try to keep up on ball joints and mounts.
Swirl Flaps, heres a video i made on that...
A mod i made for the engine covers makes removing the covers MUCH easier...
...alternator clutch pulley and all idler pulleys....
I've actually seen your swirl flap video before. Mine is fine.
I'm OK with the standard torx head bolts on the engine cover. It's plenty easy enough for me.
Yep. I've had to replace an idler before. I keep my eyes and ears on this.
-REBUILD YOUR INJECTORS!...
I may do this exact thing toward the end, as I've had this recommended before. It idles smoothly and not excessive black smoke on acceleration. Haven't done a leak-off test though, which would be the tell-tale. I get a puff of black on hard accels, but it's always done that, even when it was a puppy.
And a primer on the fuel system...
Nice video. I'll have to watch it in it's entirety when I have a moment. I note your fuel pump is silver. Mine is painted black, which is original. Did you replace yours at some point?
...replace with an OEM-look android head unit...
As in my original post, this is definitely on my radar screen. I'll have more questions about this when I get to that point for sure.
