Oil pan gasket leak

Dealer told me that the oil pan gasket on my 04 E46 sedan needs replacement. There is a very minor oil leak. Price to replace is $1100. Is this a common leak, and is replacement of the oil pan gasket that complicated? Car has 114k miles on it.

This link may help. I would be VERY certain that is actually the oil pan gasket, and not the oil filter housing gasket, valve cover gasket, oil separator, or something else that is leaking though. If it is the oil pan gasket for sure, you may be able to just smear some sealant over the area that is leaking after cleaning it, or just leave it alone. I have caused myself some major grief trying to fix something that was not really broken. A small leak is not the end of the world, especially if it is just weeping slightly.

Both of my E-46's leaked to the point I had to change the oil pan gasket. I had a mess inside the reinforcement plate...oil never made it to the ground but the sand and oil made it look like a cat litter box.

The job was a 6 hour job for me... It wasn't too bad, I move slow and kind of enjoy it knowing I am saving $1000 and getting motor mounts too. The engine mounts were pretty smashed, ....but I had 135 and 185 k.

You need an engine support bracket- check out Harbor Freight- to support the engine when you drop the front sub frame, PS pump. I just lowered it, did not remove it like some do...using the jack to support the steering rack so you can get the pan out.

Don't miss the aft most two bolt you need to access through a tiny port in the bell housing.

Use Permatex Hylomar« Universal Blue Racing Formula Gasket Dressing & Flange Sealant where the seams exist on your block. Bentley calls out for 3 Bond Sealant in these areas but Hylomar is recommended in lieu of, as required on (valve cover gasket half moon shaped areas, oil pan gasket flanges etc.) Refer to your Bentley and there are also some good links in this forum:

Did you remove the Rack and Pinion? I am waiting for the engine from Harbor Freight. I ordered it 2nd day Air. To Hawaii it is like giving up your first born for this thing. Also on the fitiings going to the Rack and Pinion I have flare tipped fittings. I found a oring on the ground after I was draining the Rack I am thinking this goes on the flared end of the fitting. Is this correct? I am on day 2 still waiting because I don't want to damage anything. I have heard that heartbreaking karack too many times! Aloha...

I was successful in stemming the tide of my oil pan gasket leak. I retorqued every bolt I could reach (14 or so out of the 25 or so total). I was able to reach every bolt around where the leak was occuring though. so keep this in mind. Its been two months now and the leak has not returned. Dont know how long it will last but I am willing to find out rather than drop a grand or so for just that right now.

Mahalo

Aloha and thank you for responding to my thread. I am still a little in the dark about the oil dip stick tube. There are three rubber oring that seal it in right? That is what the dealer told me when I ordered the orings for replacement. Also I loosened the fitting from the powersteering pump to the rack bcause I figured I had to remove the rack anyway. There was a small oring I found on the ground later and I am thinking it go's on the fitting in rack. MAhalo for all of your help and Mahalo.

Mahalo Gcoop but I already ordered the tool 125.00 and all of the parts. Oil Pan gasket 60.00, Motor Mounts 125.00 O.E., Lower Control arm bushings Urethane 150.00, Oil Level Sensor 100.00, Boots for the Rack 180.00. Peace of mind priceless... This job would have cost me a pretty penny from the stealers. Mahalo Braddah...

I am not kidding

No one here had the boots in stock except for the dealer. I should have waited and bought it from ebay for a fraction of the cost. NAPA had one for 34.95 and on ebay it was 20.00 ea. but I needed it now because I borrowed the tool to remove the tie rod ends from the tool rental guys. I should have bought the boots then rented the tool ahhhhhh. What can I say. Yes Dealer price is here is 96.94ea. so more like 200.00 but I got a discount because the guy felt sorry for me so I got it for 180.00 and some change. I had to order the orings for the oil dipstick tube from them because they did not have them all. There are 3 of them I wonder how much that will set me back... How did you get the dipstick out is there a groove or do you just wiggle it out. I am still waiting for the tool brace from harbor freight. Due in Tommorow... Aloha Brada

Im fairly certian my oil pan started leaking causing an even bigger oil leak than was already existing due to small leaks from my valve cover gasket and oil filter housing gasket. If its the oil pan thats causing the increased leak, should I really care? I was thinking the gaskets started getting worse, but now i know its the oil pan. Do I really need to have my oil pan sealed. Seems like it just holds the oil anyways.... Id rather deal with the leak for a few months until I get a new car at the end of the year (4 months away). Oppinions on this anyone?

A friend of mine is a full time BMW mechanic. He has a saying that goes like this:

"Wanna know when your BMW is low on fluids?" "when it stops leaking".

In other words, they ALL leak something, somewhere, sooner or later.

Unless you loose an obscene amount, I say let it ride.

Oil leak

The rule of thumb is. If your car is 10 years or older and it leaks less than 1 quart a month it is normal.

Me personally half of that and I strat tearing things apart. That does not meet my standard.

I was just told I need an oil pan gasket to fix a leak (approx 1 quart over 3 months) the initial quote was $1600 but was quickly discounted 25% through "value pricing". Sounds like this is not a necessity until it becomes a bigger leak? I put $3k into the car last year and re-considering whether it makes sense just to replace it as the maintenance is beginning to add up. It is 8 years old and has 93k miles

Yes, but remember all of that oil is flying around under your vehicle as you drive. A lot of things have to came off to get to tahe oil pan gasket. I wish you well my friend.

$1,200? That's too much.

Shop around for some reputable shops. Also, make sure it's your oil pan gasket. It could be a number of different things leaking.

90% of rear main seals leak after 100k miles. Even if you repaired the oil pan gasket, it won't stop the rear main. Let it ride.

However, I have replaced an oil pan a couple times, it is easy. Videos of front subframe removal on my youtube page. It is roughly 8 bolts to get access.
