DaV8or Posted January 3, 2012 Report Posted January 3, 2012 I just installed my first oil filter, sadly it seeps oil a little. I cleaned the gasket suface in the engine with a rag and it looked OK to me. I liberaly applied engine oil to the gasket surface of the new filter. I torqued the new filter to 18 ft lbs as instructed on the side of the filter and safety wired it up. Too me, 18 ft lbs seems kinda wimpy, do you guys use this torque spec, or do you go more? IIRC, when I watched the A&P put the old filter on over at Top Gun, he didn't use a torque wrench at all and just made it good and tight. When I took it off, it was indeed good and tight, in my estimation, way more than 18 ft lbs. I'm really disapointed because I have been changing filters for decades on cars, boats and trucks, and I have never had one leak before! Quote
sleepingsquirrel Posted January 3, 2012 Report Posted January 3, 2012 Did you take the gasket off the filter and lubricate both sides of it. That might work. Quote
DonMuncy Posted January 3, 2012 Report Posted January 3, 2012 Most folks (especially MSCs) won't admit it, but everyone I know puts more than 18 ft pounds on them. I've never checked the torque; it is a feel thing. Pretty tight, but not really cranked down. Quote

DaV8or Posted January 4, 2012 Author Report Posted January 4, 2012 I'm gathering by the wrenches you all are showing me that people really aren't worrying about torque spec too much. Just make it tight enough. Is this true? Quote

Hank Posted January 4, 2012 Report Posted January 4, 2012 My pliers are from Sporty's. They are functional, but often difficult to grip both wires simultaneously--one often pops out to the side. As for the wire itself, I put it around the base of the Oil Temp sensor. Keep it BELOW the insulator, and wrap it tight or it will ride up and peg the Oil Temp needle whenever the Master is turned on. Quote

Hank Posted January 4, 2012 Report Posted January 4, 2012 Never heard of Brown Tool, but my A&P uses reversible pliers [~$150] and he really likes them. I'll have to ask what brand they are. Quote
fantom Posted January 4, 2012 Report Posted January 4, 2012 Needle nose pliers for do the trick fairly well, even when you have a good safety wire plier. Quote

garytex Posted January 5, 2012 Report Posted January 5, 2012 A smart old A&P showed me this trick. Problem was that on O-300 engine with oil filter adaptor the filter had to be honked down to not leak. Summertime oil temps were always over 200 dF, sometimes 235. If lubricated with engine oil, the filter would stick. His suggestion, Dow silicone dielectric grease worked like a champ, never stuck, lubricated the filter gasket during tightening, and perhaps yielded a better seal. Maybe because the gasket slid around without being stressed during tightening, or maybe the grease actually sealed it. Anyhow worked fine lasta longtime Gary Quote
jetdriven Posted January 6, 2012 Report Posted January 6, 2012 Supposedly people use Dow DC4 to prevent the filter o-ring sticking. It can add to the silicon reading in the oil analysis (silicon) as a false spike. I use Mobil 1 synthetic oil to lubriate the gasket. No breaking down, no false silicon reading in the oil. Quote

johnggreen Posted January 7, 2012 Report Posted January 7, 2012 I change the oil and filters on all the equipment at my ranch (and sometimes on the Bravo). That's about ten or twelve changes a year. Over the years, I found a "trick" that works, or must, since I haven't had a leaking filter in decades. Grease the gasket both sides then, as you hand tighten, when the gasket begins to seat, back off, retighten, back off, retighten. Do this about five or six times. Unless you have a bad gasket, which happens, or a boogerred seat, the gasket will settle in without wrinkling. Unless something is wrong with the gasket or the seat, the filter should not leak with nothing more than the torque you can put on it with your hand. I then use a wrench to put 1/2 to 3/4 turn on the filter, but NEVER more. Jgreen Quote
