I just noticed last night that the new AC Delco filter I installed has a drip. It could be coming from another source, but by the way the whole thing is covered, I'm assuming it is leaking at the gasket. Did I twist it on too tightly? How tight should I turn it?
Well I use a filter wrench with a 6 ft long peice of pipe:Brow: I figure I don't want the filter falling off:Brow: OK, seriously now, it could be a defective filter gasketo No: I had 1 do that years ago. I've always changed my own oil before, and never had a problem with too tight or not tight enougho No: But did on that 1. Didn't seem to matter what I did. So I replaced the fliter, end of problemo No: Dan:3gears:
Hmmmm, a mystery leak. I would HAVE TO find it because it would drive me nuts until I did. Even if it was a little dripo No: Dan:3gears:
Used to work for a oil change shop years ago... Hand tight was pleanty... Or like hand tight then give it 1/8th with a Filter Wrench. Can't help with your leak though.... If its allways been wet, I'd check the pump housing gaskets, and make sure the bolts are tighto No: Good Luck:TU:
Hand tight is plenty tight enough. Just get it tight, and twist about 1/4 turn more, and thats plenty. Did you lubricate the gasket on the filter before you put it on? You're supposed to lubricate them because it allows the gasket to just slide while you're tightening it, and it prevents the gasket from sticking to the oil filter adapter. I've seen people who didnt lubricate it, and tighten it too much, this can sometimes cause the gasket to get real tore up. Not to mention it's insanely hard to get back off...
I have ALWAYS used the following philosophy and it has never let me down my entire life: After the gasket touches the surface of the oil pump, 3/4 of a turn more and you are all set. You MUST make sure you put a film of clean oil on the gasket prior to mounting or the gasket may have a tendency to "pull" and distort as you tighten, thus not making a proper seal. I'm sure you know that anyway. I have had one bad gasket in my entire life, the leak was so obvious it didn't even require guessing, the oil was pi$$ing...so I got a new filter and all was fine.
Maybe the seam where the filter is crimped together is leaking? The way things are made today, that would not surprise me. One a/c filter I bought last month was missing the drainback valve! :bglasses:
Be sure the gasket came off with the old filter. Had that happen once. Double gasket will leak for sure. Stating the obvious.
Thanks all. I'll throw a new filter on it. And yes, I always lube the gasket with fresh oil before installing.
My OP sending unit, or the line in, have a little seepage, but none gets on the filter at all. I hand-tighten a good 3/4 turn, never have had a leak at the filter.
Hey Jeff, my new AC filter and PRIMING the pump before my initial start-up, blew about 3 qts onto the garage floor:af: Maybe they had a bad batch.. The gasket LOOKED good. no matter what I did, it did more than leak. I put a new one on and it was fineo No: I also had an out of the box AC that had a double gasket. Are they making these in Mexico now
Hand Tight and here's the torque specs over the years: 18 years old (young strong and ready for the world)----- 55 FT LBS 25 years old (started dating wife)-----------------------------22 FT LBS 29 years old (first 2 months of new baby)--------------------5 FT LBS MID 30's (muscles weaker and hurt more)------------------40 FT LBS Next 10 years (Some of you may know better)-----------?30 FT LBS As you can see, hand tight varies for all of us over the years. I plan on leaks in the future too!:grin:
