I have an oil leak I was told it might be oil pressure sender unit, 1st picture if I understood instructions clearly, but it seem dry and the area under that where I would assume is some sort of oil pan is wet looking, second picture.

one of the bolts was covered in some nasty mud looking goo that feels like oil or grease.

after sitting and watching it definitely seems to be coming from the lower region I'm calling the oil pan but here is a picture of goo

You need to clean the area thoroughly then run it to positively identify the source of the leak. It can be helpful to spray it with baby powder or the like as that will show the wet spot quicker.

yup that's what I did last night was clean the crap out of it I'm going to be doing some more cleaning to it this weekend. But just so I know for the future when I order parts what is that bottom part of the engine called.

There's the lower engine case, bottom halve of the case. Oil cooler, oil pressure sender switch, switch shield. There is an oval O-ring that's divided in half by a section, sort of resembles a squared off figure 8, that seals the oil cooler to the lower engine case. That's a rare item to find, Honda quit supplying those years ago.

ok well I'm pretty sure it is just the gasket to the oil filter. atleast that is what I'm guessing. after cleaning the **** out if it. that is where I found oil this morning.

A lot of the oil filters sold don't come with a new O-ring gasket so people reuse the one that's there. There's also an O-ring on the filter bolt that should be changed.
In some cases the cover has warped over time and even with new O-rings they still seep or leak, in that case you would put the cover on a piece of sand paper that's on a flat surface and using a figure 8 pattern sand it to remove some material. Visually check that the O-ring stands above the cover to gauge when it's done.

any good suggestions for websites to get those or parts in general.

I use WIX #24939 which I can order from almost any auto parts store. Wix Filters - Product Catalog search results I order 6 at a time so I always have at least one handy

I got my last batch from 4 into 1. Emgo with the orings. Good prices and good service, IMHO.

I got a whole kit on ebay for like $40 with everything: oil, filter, and 3 gaskets. I know the little o-ring looking one is for the filter bolt and the kind round kinda square one goes to the "oil filter pan" but what does the large o-ring that is about the size of the one for the "oil filter pan" go to.

 

[dtsmjr8dan]

The large round oring is not used. $40 is a little much, I would think. $4 filter, (3 X $6) $18 for oil, all told comes to $22. What else did you get for $40 ?

 

[mellowhobbit]

ummm maybe it was 38 but yeah that is what I got 3 gaskets 3ltr of oil and oil filter. all honda parts so that might be why it was more expensive
