"In this segment we're going to cover, adjusting exhaust valve, cylinder #3, part 1. And we need to change our fueler gage cleaners on the exhaust side. It's a little bit more clearance in the intake side. And it's .0059 thousands to .0075 thousands. And I may not have clarified that a little bit earlier. That's actually between 6, or somewhere ruffly between 6 and 7 thousands of an inch; .0059 to .0075. And we'll just follow the same procedure once again. First breaking, retaining that free, then I'll loosen up the center, insert the fueler gage. The first time in always seems to be just a little bit more difficult, because they have oil and residue built up in there. Well, you want to be careful about stuff like that. If it should fall down and happen, it's not going to go through the oil drain passages, the smaller tool could easily do that. And it may or may not make it to the oil pan where it could be recovered. And once I've got that in place, and my locking nut helps, I'll back off on it. Then turning clockwise again, because that was snug, about 15 degrees. Check the clearance, tighten it down. And they still feel pretty tight. I'm going to do another adjustment on that one. Sometimes this can take 2 or 3 times to get it just right. And that's just kind of, get a little bit better at it as you do it more often. But the other part of the equation is, oil residue that builds up underneath the cap itself and retaining nut, and as well as a lubrication between a camp shaft and a rocker hard. Following the same procedure we've been doing on the other valve. And, that freed it up. I'll check it one more time, good drag tight fit, excellent. Now I'm just going to re-check, make sure that I got this retaining nut tight and secure. And that will conclude adjusting a exhaust valve, cylinder #3, part 1. Please watch our next segment on, adjusting the exhaust valve, cylinder #3, part 2."
