I replaced my cabin air filter a few days ago. It was making a noise and so I went in again to remove the leaf sitting on the blower. When I took my new filter out, I noticed it has blue stains all over it. The only thing I can think of is that I went through the car wash and it might be the soap they use (rainbow color). But I'm not sure how soap would find its way into that area. Or is this something leaking??

Someone else may answer better. But I believe there is a flap that should be closed when HVAC isn't in use. But I would remove filter and take a light and look in there. I also had leaf on top of filter.

Could be wiper wash fluid getting past the cowling? Have you ever noticed water blowing out from the fan during a bad rain storm?

I had a problem with my 2008 Toyota where water was getting past the windshield cowling into the blower motor. Safe-lite half ass'd the re- installation of the cowling trim after putting new glass in. IT caused a leak.

Have you had the windshield replaced?

Never had water blowing and never had the windshield replaced.

I always smell the washer fluid when running the wipers and AC, it could be the washer fluid, same color? Could very well be the soap

I had a leak going into my cabin air filter. It was the plastic cap under the plastic cowl cover. The sealant around the plastic cap, which resides right above the air intake for the cabin, was no longer adhering to the metal of the cowl and water was slowly entering thru it. Once I removed and sealed it, no more dripping down thru the cabin fan.

      Exhaust Question

      By C. Hart · Posted

      I have seen different people in different places post different sizes of exhaust as stock for my 2014 Sierra L83. Some say 2.5 some say 2.75. I am considering replacing the muffler with a Dynomax Super Turbo, perhaps 17739.  I had the factory L83 5.3 replaced with another L83 5.3 from Jasper Engines. I also put new Walker Cat / Y pipe on. I would appreciate opinions suggestions about what would be a good muffler setup. My main interest is a low rumble and the best flow / fuel mileage I can get. Not interested in straight through glass packs or loud exhaust. Those days are way behind me now.  Thanks Guys.

      Cold start Miss, oil in cylinder

      By newdude · Posted

      Its coolant disguised as oil.   TSB 20-NA-166 -  20-NA-166 1..3   "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix"     I'd say its the head, and its either leaking at the casting line and dripping down the intake into the cylinder, or its another spot on the casting itself at the cylinder that is getting wet.

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
