" From: Matt Haas <mhaas@xxxxxxx> " " " It's been a couple of years since the car ran and it's making a nasty " clicking sound in the valve train. I'm hoping that it's just trash in the " lifters. Anyone have any suggestions for something I can dump in the engine " to try and quite things down? The car has a 199 six with the early style " shaft rockers and it looks like there's oil getting to the rockers. gunk brand motor flush. take your oil down a quart [i've always just waited until i was a qt low], run until warm, add flush, idle ~15 minutes, change oil. the first time i used it i let the engine idle longer than 15m, more like 30. the idle which i thought was good, increased slightly and smoothed out and a ticking lifter [sic] stopped. i couldn't dump the drain pan right away but when i did there was a metric buttload of sludge in the bottom. i was also advised it would ruin my seals as hardened sludge was the only thing holding them together, but oil consumption went down afterward, from 1000 to 1500 miles/qt. this was on a '66 ex-at&t fleet car with 199 and probably over 200000 miles on the clock, in the early '80s. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
