Icon6 Oil leak near Oil Filter

I own a 1997 Honda Accord LX, 4-door sedan. Judging between what I can glean between my owner's manual list of engine specs and what I've been able to gather from Wikipedia, my engine is an F22B2. I am not 100% certain of this, maybe 90%, but specs are at the end of this post.

So here's the deal: it's got 212,000 miles on it, still runs like a champ, but it's developed a leak from right where the oil filter screws into the block (?). Not pouring out, but a fairly steady drip while running, intermittently at rest. My mechanic says he can't fix it, advises me to find someone who can (and would) seal the crack (or whatever the opening is) by welding it closed. One of the mechanics said aluminum welding, the other disagreed. Assuming some sort of welding will be required (please disagree if so inclined), I'm desirous of being able to describe to the welder exactly what and where to weld but lack any fotos or diagrams or labels to convey this information.

From my research, and from the VIN, I've been able to ascertain the engine was manufactured at Honda of America, the VDS is CD563 (I understand what the VDS means but not what this CD563 means, per se), the serial number of the engine itself (digits 12-17) is 059665.

I want to keep this vehicle for sentimental if not financial reasons. My question to you is: from what I've been able to describe, does my mechanic's solution sound valid to you? i.e., would it require aluminum welding to seal? and how would I convey this to a prospective welder?

('better too many specs than too little' was my thought)

oil pressure switch, then go for oil filter housing to block o-ring, I think maybe it is called the oil cooler o-ring.

What Poorman said, try the oil pressure switch. It's mounted right above the oil filter. That's what was causing my leak.

there's an o ring on that cooler block. my car had a leak (major leak) from there at some point.

very easy replace once you get under there. oring itself costs about 2 dollars from dealership.

F22B2 has oil cooler??? I know the H-Series does but not my F22B1, so that makes me think that B2 won't have one either, but I can be wrong.

OP, it can be your oil pressure switch thats leaking.

Clearly you need to be absolutely sure where it's leaking from. Check one more time. I would think if it's a crack it'd be a fairly big leak considering the location.

Default Re: Oil leak near Oil Filter

thanks, all!

so far the only "disagreement" is the advice from my mechanic, that it would require welding to solve. i definitely prefer your solutions and those of the others at honda-tech. it will be interesting to see which solution actually solves the problem, and/or whether i need to look for another mechanic, although his solution would not have lined his pockets, either. at least he was able to identify the source or general area of the leak itself.

i'll be sure to keep y'all posted and thanks again.

Here's the oil pressure switch the guys are talking about. Mine was leaking like crazy a couple years ago, but the part was really cheap and easy to replace. Make sure to drain your oil first if you try it.

iF Your "mechanic" can't fix a simple leak like this, he isnt a mechanic at all.

If it's the oil pressure switch, assuming it's not faulty, all you need to do is take it off and add some teflon tape to the threads and put it back on. But they are cheap so you could easily just replace it.

Nus-I was reaching on the o-ring, I'm old and get confused. I know some have the o-ring, some don't......that is why I asked for help/confirmation....Thanks.

EDIT:wait, I see that this was on a different site...sorry.

Mine starter leaking around a year ago and I first took it out, re honda-bonded, and reinstalled. Still leaked!

It turns out it was leaking through the internal housing, so it had to be replaced with new. Have not had a leak since.

You dont need to drain your oil, but you will gain better access with the filter removed, and that seems to drain the residual oil from behind the switch. Dont over-tighten or you will strip the threads (obviously).

HONDA TECH RULES!

Kudos to All of You!

Here's what I've received so far:

From HondaPlatinum @ JustAnswer:
What else would you like to know . If it's is a crack Hinda bond will seal it . If it's the oil filter oring replacing the oring will fix the issue.

From Poorman212 @ Honda Accord Forum (HAF) :
Saw this somewhere else......Again, I'd have someone check the oil pressure switch. Also the "adapter" that the oil filter screws onto has an o-ring (need help for the proper name and part number...help me here folks) behind it that will sometimes leak.

From Poorman212 @ Honda Tech (HT) :
oil pressure switch, then go for oil filter housing to block o-ring, I think maybe it is called the oil cooler o-ring.

From UgandaHonda @ HT:

Not being a mechanic myself and for some reason feeling loyal to the first mechanic I chose when I arrived in Maryland, I am giving the guy another chance but am also forwarding on to him all of your combined input. Not one of you suggested, as my mechanic did, that I'd need to find someone willing and able to seal the leak via aluminum welding. Y'all have saved me a bundle, I'm thinking. Thanks.
