My 2005 civic just started massively leaking oil near the bottom behind the big time belt pulley.

I have reason to believe it's my crankshaft seal.

I just ordered a timing belt kit off eBay so let's see if replacing all these seals fixes my problem

Beware of cheap ebay parts. If you aren't using factory parts, you may cause yourself much bigger problems.

replace your cam seal while your in there

bsoto

Yup also replacing that

mitsuboshi are good belts,

two things in that list wave a big red flag to me, the tensioner, and the water pump, who are they made by?

do you have a link to the listing

http://m.ebay.com/itm/260810395426

Tensioner and Idler Bearings either from NSK, NTN, GMB, NACHI, etc.
+ High Quality Water Pump from NPW (NPW - Nissan Pump Manufacture Inc.)

huh?.....how can they not be sure which product they are going to ship you?

the only one in that list i would trust is NSK,

just a FYI, a tensioner failure on these engine causes SEVERE ENGINE DAMAGE, this is a part you want to be sure you can trust for the long haul

bsoto

I will look for a trusted tensioner locally if I don't recieve an NSK.

ezone

The only thing I trust for this is the one that comes from a dealership parts department with the correct HONDA part number on the package.

Man..... i'm so disappointed.

Took everything apart today and right away i noticed my camshaft seal was busted out. So i figured that was the issue instead of the crankshaft seal.

Drained all my fluids...

I replaced all seals, timing belt, tensioner, water pump....

Then refilled my fluids

Car started instantly no more leaks... but once i drove it around the block and pull back up to my driveway i noticed it was leaking oil AGAIN!

Its not leaking as much as it first was ( making puddles )

But it is dripping a drop every 30 seconds or so...

What do you guys recommend i do?


This is my daily driver and i haven't been to work all week cause its been down.

Im at the point where i might just get a new car but i love this car to much to let it go.

If i end up parting with it, do you guys think a Honda Dealership will take it in as a trade-in with the oil leak? If i plan on financing a new civic with them?

See why it's leaking.

Pull the top cover off, see if it's leaking at the cam seal again.
See if the outer lip of the seal isn't covering the surface of the cam and needs pushed in deeper than flush.

bsoto

We pushed it in pretty good as far as it would allow us

I'm pretty sure it popped out just a bit again but it has to be a reason why it's doing it right?

ezone

PRETTY sure? You need to find out for certain. I've not had any factory cam seal "pop out" on this engine.

Did you use aftermarket seal?

Is the drainback path clear? (If there is one, I don't remember. Gotta look. Sometimes driving a seal too deep can cover up the drilled drain hole.)

No excessive crankcase pressure?

Rust or rough cam surface where the lips of the seal ride?




Found a pic, this original cam seal on a D17 was installed about 1.5mm deeper than flush.

bsoto

Taking it apart again later today to confirm it is the cam seal...
I did use a honda seal Part Number: 91213-P2F-A01
no excessive crankcase pressure, no rust or rough cam surface but it did slide in pretty easy

It did go in about the same 1.5mm deep. When i first removed the cover yesterday i immediately noticed it was out completely

ezone

That's odd to me. No other ideas for why yet here, every one I remember installing took some effort to install.

I'm not aware of anyone making an external seal retainer for this application.

bsoto

Yup my crankshaft seal took a while to put back in, but the cam seal slid right in which was kind of odd to me also.

But like i said ill be taking the top cover apart later today to confirm it is the same cam seal (im 90% sure it is)

I also just ordered another seal from Honda picking it up tomorrow morning and replacing it again during the week

ezone

An old trick is using a punch to "dimple" the surfaces where it fits too loosely. The metal raises around the dimple, and should make the fit a bit tighter. You'd have to take off the cap and maybe take out the cam to dimple all the way around, then insert the seal and bolt the cap back on. (do not pound the seal in across the new dimples)

Figure 3 in this link and the related paragraphs may explain the dimpling idea better: http://vacaero.com/information-resou...-punching.html

This was just the first idea that popped in my head, there are probably other ways to make the seal stay in place too.

bsoto

But eventually I'll possibly keep having issues with it most likely right? Unless I swap out my head or engine entirely? I'm guess the cam is worn out like I said not allowing it to seal fully


Someone just offered me $3,000 cash as is kbb is valued at $4500
Should I just take the loss and give up on it?

ezone

Not if it's fixed.


I don't know why you would think this.
It can't be a camshaft problem if it pushed the seal out of the head.

Have you taken it apart yet to see what the problem really is this time?
Quit guessing worst case scenarios until you do.

I can't get rid of problems that easy.

bsoto

Took it apart and yup it's popped out again.



I took the easy way out sold it for $3,000 to avoid headaches... As you known I've had to spend money on my transmission and ecu so it's not worth me to keep putting money in it.l and keep having new issues every month. Just gonna use those $3k and throw it down on a '14 civic
