Point of information: I added some Pentosin to the hydraulic chamber a few days ago, and probably spilled some. ................... Doyt, I was gonna take a shot at it and then I read the above. Coincidentally, I added some Dexron Hydraulic fluid this week & spilled a bit. When this stuff hit the exhaust, man what a smell. My money's on the pentosin. Jeff 86 4KCSQ Daily Driver 86 4KS Spare
