Just installed a set of UMI double adjustable rear LCAs with the roto-joint. I have not tested them out yet. Also a couple months ago I changed out my starter and battery and fixed an ongoing start up issue.
I changed my copper plugs out for iridium's today, found out cylinder #8 was hanging off for the last year. Put the new ones in and my car doesn't tick like a freaking tapping sound anymore. Cannot be more happy.
Dude Across the Street took the PCV out and installed a valve cover breather, but left the hoses hooked up to the intake and the throttle body. He couldn't figure out why the car died at idle all the time. He had it TUNED with no PCV.
After reinstating the sealed system, it runs better, but it still has issues.
Kitbashed the PCV system.
Microguard PCV178, 6" 3/4" hose, hose clamp assortment, brass 1/2" NPT to 3/8" barb adapter. $13.00
Installed MOOG CC635 rear coils. Raised the back end about 2 1/2". MUCH tighter. Old, OEM coils had about 200k miles on them. $43.94 shipped.
Slowly but surely, I'm trying to get his car finished. But he doesn't understand processes. If the steps are, "A then B then C then D…" he wants to run it like, "A then B then 'OOH! SHINY! Let's do THAT!' then X then Q then 5…" and there are NO numbered steps.
But I digress.
I removed the massive vacuum leak created by an open breather system hooked up to the intake, reinstated the sealed system with a functioning PCV loop, and replaced the rear springs.
Okay, after many configurations, we settled on one we think will work until 'Dude Across the Street' can get his '98 Z to the tuner.
LS1 intake, right? The PCV system is a mess. He had the intake port going straight to the driver's side rear valve cover port, the passenger's side front port going to the "air bridge" on the throttle body, and a breather cap on the passenger's side valve cover oil fill. No port on the rear of the passenger's side valve cover. Still, MASSIVE vacuum leak and no PCV. Bad, bad, bad.
So, I tried replacing the solid oil filler cap and installing a kit-bashed PCV holder between the intake and the driver's side rear valve cover port. I left the hose between the passenger's side front port and the throttle body. Worked well, but I wasn't getting any vacuum from the passenger's side.
So, I tried capping the passenger's side valve cover port and the throttle body port, and just pulling vacuum on the driver's side valve cover. Still no vacuum on the passenger's side.
So I left the throttle body capped, capped the intake port (disconnected the PCV), and reinstalled the oil filler breather cap. That worked, but once he saw the blow-by coming out of the breather, he said he didn't want that messing up the engine bay.
So, I left the throttle body capped, reattached the intake port and the PCV, and teed the vacuum line behind the PCV (between the PCV and the drvier's side rear port) and ran a second line to the passenger's side valve cover. Now I'm pulling vacuum on both sides with no air inlet in the system. With that Torquer V3 cam, he's not pulling a lot of vacuum to start with, so I hope this works.
We shall see…

Cool! Yeah mine taps like crazy, I have the stuff to do it I just need to git er dun! How many miles do you have on yours? Mine has 130k...
Not just today, but picked up a new to me 99 SS. Mostly overlooked maintenance and stuff needed to repair to pass the MD inspection. New wheels because the other ones were trashed. Paint overall is trashed, questionable install of some mods, shocks are toast. It is definitely going to be a project.
