Hi,

I have a oil leak that is getting worse and leaking all over my belt which is sending oil all over my passenger side engine bay. It leaks during startup. After about 5 minutes it stops leaking. Please see photos it looks like an easy fix if I was able to remove it. I cannot because there is a (what looks like) a bracket blocking access to remove it.

Please help with with a part name and/or how replace this. I am assuming there is a gasket that needs to be replaced.

Thanks in advanced.
46707


46710

This is where it leaks from ^^

46711

It’s from the metal - metal contact on what looks like part 13 ^^


46709

I cannot access it because the bracket that the power steering pump it fastened to is in the way.

yes, it's a gasket with filter for the VTEC oil system. Part# 15845-RAA-A01. You can get aftermarket, but they are only about $15 from the dealer. This is the front side, and the rear VTEC Solenoid is the opposite end of that system and another common leak point. That's where my leak is, and I'm about to replace both gaskets since if one is bad, the other is probably pending.

Yes, from what I can tell, you have to take the drive belt off, then unbolt the PS pump (can leave hoses connected?), then unbolt and remove the belt tensioner (might be a good time to check the pulley, or maybe replace this whole assembly while you've got it removed). When you take that little cover off, oil is going to spill out, so be ready with rags/etc to catch the oil. Some videos say to put oil on the gasket, but in my experience oil will degrade rubber and plastic, so don't coat the thing with oil - just clean it well and be sure it's all dry before installing the new gasket.

The part number for the rear solenoid gasket/filter is 15815-RAA-A02. Also there is an o-ring on the pressure sensor which is in that solenoid module that was recommended to replace at the same time, part# 91319-PAA-A01. I got these part numbers from youtube videos on replacing the vtec solenoid gasket. Some were more helpful than others. As my mechanic showed me, you can do the rear gasket by reaching over the top of the engine, but that is much easier if you've done it a couple times before, because you're kinda working by feel. My mechanic also said they don't do gaskets anymore and replace the whole solenoid module because they were coming back still leaking. I don't know about this - the solenoid module is like $250, so I vote try the gasket first.

Thank you Doolick, I bought the gasket today and replaced a couple minutes ago. No more leaks, I really appreciate the guidance. It took me about an hour and a half to complete.

sweet! I'm curious - how much oil leaked out when you took that cover off? We just had the oil changed, so I'm not going to drain it first.

I did not have any oil drip out, I had the car sitting for about 2 hours before starting this though. The oil did look to be right at the level of where the opening is. I would play it safe and put a couple rags underneath, but I wouldn’t worry about adding more oil.
Good luck!

Donnell,
That is just the attachment point for the oil filter, not an o-ring. There are 2 parts attached to the rear solenoid module that each have o-rings. One is detached with the 2 screws as shown in pic #5, and then the other part is right next to it, but you use a socket or wrench to unscrew it. This poster replaced the o-ring under the part with the 2 screws, I replaced the other one. Probably you should replace both, but I had trouble finding the part number for this one. See my link to the other post with part numbers.

is this the front solenoid?

way too small to be where the oil filter goes and it looks like he has three independent parts in his hand

There is no "front solenoid". There are technically 2 solenoids - there is a VTC(?) solenoid on the driver's side that we are not concerned with. The one we are referencing here is the VTEC oil pressure solenoid, which is mounted on the rear of the engine (passenger side). That pic is of the entire solenoid module, including 2 devices that attach to it, and one of the devices has been removed to show the o-ring (in this case that one is really a circular gasket, but that's a technicality).

There is a primary gasket with filter between the solenoid housing and the block. Also, there are channels that run through the block to the front, and there is simply a cover there with a gasket/filter that you should replace at the same time (requires different work, but if the rear gasket is failing, the front one will, too). I'm not sure how fragile these components are - I was very careful when disassembling and did not use any spray cleaners. I used rags and a tiny bit of degreaser on the rag to clean the mating surfaces. Mine was in pretty good condition though.

** Do not put oil on the gasket before reassembly. Oil breaks down rubber, so that's silly in my opinion. You DO put a little on oil filter gaskets so they don't "stick" and are easy to remove at the next oil change. But we don't want these gaskets coming loose. We want them to stick and seal off permanently - which means clean metal against clean rubber.

See my other reply -
yes this gasket (maybe o-ring but really it's a gasket) I never found a part number for - probably have to go to the dealership parts counter and they can find it. Maybe I couldn't find it because I was searching for o-ring, but none of the "kits" that have all 3 parts below come with a replacement for the one pictured above.

So, other than this mystery part, the numbers are:
Front cover gasket = 15845-RAA-A01
Rear module gasket = 15815-RAA-A02
O-Ring on pressure sensor (black part near his thumb, above) = 91319-PAA-A01

- or you can get a generic-brand entire replacement spool valve (aka oil pressure solenoid module) off ebay for about $50 (no promises...), plus the front gasket.
