Hello all, a long while between updates, but after 2 years of relative “stress” free ownership, I’ve been spending a lot of time messing about trying to get some nagging issues still resolved.
Since my last post I did change the rod bearings (just in time it would seem after seeing the post regarding their supply issues), though it seems like I did not get a good seal on the pan as I’m still having a fairly noticeable leak. Will soon attempt to redo the pan gasket to hopefully rectify this.
My larger issue at hand still seems to be related to the original issue that plagued the car when I started this thread.
The car starts every time without fail, although it’s still typically a rough start up, especially when starting cold. Once running it stays running, drives well, no real noticeable issues. It’s served it’s purpose as a vehicle to get me from A to B for 2 years now.
Unfortunately the car feels far from running smooth. I’m still being plagued by codes 332, 558, and 565. I’ve replaced the DPFE, EGRV Solenoid, and CANP solenoid to no avail. There’s also a fairly noticeable ticking noise at idle that from reading other threads sounds like it could be the chain tensioner perhaps? Not entirely sure. The car still smells like it runs extremely rich and I’ve noticed fuel seemingly leaking around the fuel line connections, as well as a general exhaust leak that I haven’t traced.
In complete honesty, I feel like I’m at a bit of a loss here and I decided to ask for some general thoughts and tips on what to chase down next on a laundry list of issues.
I’ve attached the photos here that I’ll try to give a brief breakdown of why I’ve attached them and will upload a video soon as well to try capturing the ticking noise I’m hearing.
The fuel lines: Obviously the leaking and strong gas smell, in the past I’ve noticed a gas leak coming from the attached union bolt on the fuel rail. Could the rough starts and excess fuel being dumped during that potentially be causing this fuel leak? After tightening the bolt a while back it stopped leaking from there, but now it seems it’s started to leak from there fuel lines. All of that said, I’m not noticing any drastic fuel economy issues.
Vacuum line from TB to CANP: I’ve been attempting to track down any potential vacuum leaks and I first replaced this line when I originally had the intake apart, though I could hear a noticeable hiss from it recently. Decided to replace it after discovering it was not the correct size, but the hissing noise remains. If I pinch this line it stops, almost exactly as the line that was on previously would do, but there’s no noticeable damage anywhere on the lines. I also recently replace the TB gasket thinking that could have been the issue, but the hissing is definitely coming from this line.
Finally, the last two pictures is a line I noticed that was broken just about a day ago. If I’m not mistaken it looks like it goes to the Evaporator core at the firewall. At first I thought it was the line breaking off from the vacuum T at the bottom of the CANP solenoid but I’m not entirely sure. I’m looking at anything that could help solve some of these issues so again, just attaching for the sake of finding things wrong.
Any help, tips, advice, anything at all is greatly appreciated! I can try to update some of my other tests/findings I’ve done through the past 2 years as well, but I was attempting to (though failing) to keep this relatively brief lol
