Back to Baselining...
Well after a fun project that was more of a build item, I have som more issues that still need to be dealt with. I have a number of small exhaust leaks to deal with, but first some background (read: long winded storytelling from a dad stuck in COVID parenting zoom school purgatory, who dreams of GTFOD and scratching the deep itch of wanderlust).
A few weeks ago I replaced another exhaust cushion, this one at the front of the muffler, after some severe low idle and near stalling at a stoplight. I replaced that cushion and things seemed to be better...however ive noticed my idle seems really low once the rig is warmed up. At stoplights its idling at 400-450 rpm, and seems a bit rough. After the exhaust cushion pooped out there has likely been lots of extra vibration and free play in the exhaust and I suspected that there were some leaks....so I busted out a shop vac and some eco groovy soap and went hunting around between rain storms.
And I found that most of the joints in my system seem to be leaking, some significantly. The hardware is in terrible shape as well. I unfortunately am not great with the nomenclature of the exhaust components, so feel free to chime in if I misname anything. I have leaks in these joints....basically everything but the junction betweent he tailpipe assembly and the muffler.
In addition I fount that a couple of the EGR pipe joints are leaking as well. So my best guess is that I am leaking in some air into the exhaust system above the O2 sensors (OEM Toyota that were replaced in 2/18) and causing the truck to have a low idle. Here is a photo of a foamy messy leak....
The other photos are actually really unhelpful because of my camera and lighting, so this is simply an example of my method and NOT the totality of my search. More thought to follow...
