Car Forum / Honda Cars / October 200795 Accord DX Oil Filter Leak
Hello, I have been having this minor oil leak which I'm almost 85% sure is coming from the gasket of the oil filter. I have tried looking for leaks above the filter but can't see any. I also tried pulling off the existing filter and checking to see if an old gasket was stuck but all was clear. I've always been using Honda OEM filters. Does anyone have any suggestions as to what to try? Should I use some liquid gasket around the edge of the filter and see if that helps? Thanks in advance Nick Why wouldn't you just screw on a new filter? > Hello, > [quoted text clipped - 8 lines] > Thanks in advance > Nick Because the current filter was only a week old.

I might try a Puralator just to see > if that helps. in that case, i agree, it's unlikely to be the filter. you need to remove and inspect the seal interface - it may be scratched or there may be piece of contamination like thread from a rag stuck under the seal. if it's scratched, the only hope i can see is liquid gasket. >> If the installation of the current filter is what started all of this.... >> replace it and see if the problem continues.

The old type was larger in diameter and did not bottom on the on the filter casting, only the gasket would. I use Fram, Puraloter, Pennzoil, and I have no problem, because they are the same size as the older Honda filters. Thanks Andy, I'm going to try that route first and get a new oil filter. If that fails then I'll try the liquid gasket.

If > that fails then I'll try the liquid gasket. Do NOT use liquid gasket on your oil filter flange!!!!!!! That not only won't work but may cause grave damage to your engine if you get any of it in the "clean" side of the filter. IF in fact the filter is to blame, find out why. Don't band-aid the problem with something that will certainly cause you more trouble in the future (and make the pro's laugh at you behind your back when you eventually surrender to them). You need to be 100% certain the leak is coming from the filter, not "85% certain". Because of air turbulence in the engine compartment, oil leak sources are easily obscured as oil whips around as you drive. Change the filter with a new dealer filter. Wipe the area well that surrounds the filter mount boss. Put a /very light/ film of oil on the new filter gasket. Install to 8-10 ft lbs, but NO TIGHTER. With the car still raised, start the engine and let it idle until the engine is at operating temperature (about 10-15 minutes). If the filter is in fact leaking, oil will squeeze past the gasket and form a droplet at the bottom of the filter. If no droplet ever forms, then it's not your filter that's leaking. Your leak is more likely to be coming from the valve cover gasket, the front balance shaft seal, or a cracked exhaust manifold bracket boss (the last two are known issues on your car). The thing to do is to get the block steam cleaned (by your dealer, not you), then sprayed with aerosol leak detection powder. A short drive should then pinpoint the source of the leak. I'm betting it's the valve cover gasket, myself.

I had forgetten until you mentioned it, but there was a kit for the '95 to put a retaining bracket over the seal because it fell out so easily... --Gene >> Thanks Andy, >> [quoted text clipped - 4 lines] > won't work but may cause grave damage to your engine if you get any of it > in the "clean" side of the filter. here's the deal on that though - you're only supposed to use a smear that will fill any crack or scratch. maybe i should have been more explicit about that. i've never has a problem with liquid gasket in this way, but i never splurge this stuff about. silicone sealants otoh can be a problem, and this is something i've encountered repairing other people's work on many an occasion. unless the metal is absolutely clean, no oil films, then the silicone doesn't stick and tends to end up floating about in the system and clogging stuff. they're fine if they're squeezed tight and the seal isn't broken, but once they're broken and bits can flake off, that's when the problem starts. > IF in fact the filter is to blame, find out why.

The point is that sealing potions should never be needed. If there /is/ an apparent need for such stuff, then something else is wrong. The oil filter will seal itself properly every time if correctly installed. > silicone sealants otoh can be a problem, and this is something i've > encountered repairing other people's work on many an occasion. unless [quoted text clipped - 3 lines] > broken, but once they're broken and bits can flake off, that's when > the problem starts. Silicone is even worse. Oxygen sensors (especially today's multiple $400 sensors) do not like silicone at all.

Silicone is deadly to oxygen sensors no matter where it's applied to the engine. You must use the "sensor safe" stuff, which not everybody is going to know about. I still think it's a poor idea to advise anybody to use goop as a band-aid fix for a problem that is poorly understood in the first place, which is what's happening in this case.

I've replaced the oil filter today with a Puralator Plus since the size is the same diameter as the old Honda OEM filters. I'll report back tomorrow if it is still leaking.

Ok after investigating the issue further, it appears that the leak is coming from a hose with a wire inside of it just below the intake manifold. It looks like it goes into a cover with a bunch of wires hidden inside of that. Does anyone know what part this is? Is this something that I can easily fix with a lift?

Does anyone know what part this is? sounds like the oil pressure switch. they go frequently on some cars - not so much honda. check for tightness first. if it's already tight, just replace it and you'll be fine after that. > Is this > something that I can easily fix with a lift? just reach up there with a deep socket of the right size. can't recall right now, but it's metric. buy a new switch from honda - don't mess with after-market crap. > Thanks, > Nick [quoted text clipped - 31 lines] >>> on an interface that's going to be re-made every time the filer changes >>> isn't going to work. Ok Jim thanks for the help. I looked at my Helms manual and sure enough that is the part. I'm assuming that the wire is disconnected at the point where it comes out of the engine block? Also the plastic shield has cracked in one section should I be concerned, can I shield it with electrical tape? Thanks again for the help Nick >> Ok after investigating the issue further, it appears that the leak is >> coming from a hose with a wire inside of it just below the intake [quoted text clipped - 47 lines] >>>> on an interface that's going to be re-made every time the filer changes >>>> isn't going to work. > Ok Jim thanks for the help.
