Dropping the oil pan on 2001 MDX

that pic do not look like a leak at all...very minor sipping... re-tighten all the 10mm bolts likely fix it.. instead removing the whole oil pump...

You do not have to take my advice, if you comfortable removing everything in the future again ; if re-tighten bolts do not fix it..then go for it..If you don't mind taking that risk..

Hi HTL,

Actually the oil seeping out the bolt head is not the real leak. I ran my finger on the top of the oil pump where there is a channel between the oil pump and the block. It's all wet up there, and the oil flows down that channel toward the oil filter adapter before dripping down the side of the oil pan.

There is no way I can see up there, so my conclusion is purely by the feel of my fingers, which could turn out to be very wrong.

At any rate, since I am here already, I may as well go for it! The only problem is that I can work on it for only about 2-3 hours a night since I have a day job!

Thanks for your input, I really do appreciate it very much.

It took me the whole day, but the oil pump is finally out. Now I am baffled as to how I'm going to put it back together. I hope Supertech or HTL are reading this.

Anyway, the Helm's manual says: "Apply liquid gasket evenly to the block mating surface of the oil pump and to the inner threads of the bolt holes."

So my questions are:

1) Which surface? Oil pump or block?

2) Do I apply it as a bead like the oil pan or do I spread it out evenly with a spatula?

3) What do I do around the O-ring? I don't want to contaminate the O-ring with liquid gasket, but can I? If it's not too much to ask, can someone pencil in the picture I attached to show where around the O-ring I should be applying liquid gasket.

Thanks

the whole purpose of you removing oil pump is to replace that o-ring... you can add liquid gasket to Purple highlighted ...it does not really do anything...the o-ring in place to block the oil from the pump assembly to the engine block..

Yes, you right, don't contaminate o-ring with liquid gasket..

The only thing that you should worry about is when you put the oil pan back on..make sure you apply even liquid gasket and let it dry couple hours before you start the car...

Good job by the way

Thank you HTL. That makes a lot more sense to me now. So the O-Ring is there to seal the high pressure oil while the liquid gasket is there only to prevent oil leaking out while it is being splashed around. Is it correct?

The curious thing is when I removed the O-Ring, the O-ring groove does have some grey looking liquid gasket in there, but only on the side wall of the groove.

Thanks again for helping.

Hi all,

While I am waiting for the parts from Delray Acura, I am preparing for the reinstallation of the oil pump.

I also ordered O-rings #26 and 27 for the part #3 in the attached diagram. However, for the life of me I cannot figure out how to take that plug out. It does move a little, but seems to be caught somewhere inside and would not come out.

Is there a trick to remove it, or do I have to apply air pressure somewhere to blow it out of that hole? If so, where?

Thanks

you angle pick...or needle nose plier

why you replacing that tubbing o-ring for?

[NewMDXOwner]

Just because I'm already there and it's an O-ring which probably is hard like a rock just like anything else there.

Thanks

[SuperTech]

Don't mess with that. I never do. However the dipstick tube o-ring #25 and the pickup tube o-ring #28 should be replaced.

OK, two professionals against one amateur, I'll leave it alone.

Thanks.

Parts from Delray Acura just got here. I got home at 6pm from work, and started on it. The pump is back in with new O-rings and new front seal. The oil filter adapter is in along with the timing belt. I am going to wait until the wife goes to bed and I'll clean the oil pan in the kitchen sink. The "Supreme Commander" caught me doing that once, and I paid for it dearly.
