leak

Recently did some work to my diff including replacing the halfshaft/output seals. After a while I noticed they were both leaking but I can't figure out why. When installing them I used a bit of diff oil as lube and just slowly hammered them into place with a mallet and blunt piece of metal. Only...

Hi everyone, I took my baby home from my dad's house, approx 20-40 mins away from my house I parked in my garage and switched the engine off and had a panic attack because i started hearing a loud hissing air leak (like a tire flattening) that i was unsure about, and it wouldn't stop, knowing...

Hey Everyone, Two weeks ago I bought a 2003 330xi and I have already replaced the spark plugs, and fixed rust and now I am working on the Ebrake (just waiting to find a kit for cheap) Anyway my car is leaking oil because one of the holes for the oil pan going into the block is stripped. Is...

hello, it recently rained for the first time and I found a small spot of water on the drivers side front carpet. In the following days all my windows fogged up very easily and there were even drops of condensation on some of them. I'm planning on checking the vapor barriers as I suspect this may...

Hi all, my first post here. I bought a 2004 325xi Touring about a month ago, and have read hundreds of useful posts here. Anyway, I dropped the pan on the GM tranny, replaced filter and gasket and refilled with Redline D4. I know that stuff smells bad, have been using it for years in my VW...

My 328i seems to defiantly have a coolant leak, but I cannot seem to find out where it is leaking from... I can see (what I assume is coolant) sitting in the bottom of the engine bay (on top of the plastic cover) I don't feel any coolant on the upper or lower hoses, so where could it be coming...

Pretty new to the E46 game. I have a 2004 325ci convertible. As I was driving back home today, I see white smoke from the hood, and smell as sweet burning smell, and the engine was overheating. So I pulled over and saw that the coolant was boiling. After I let the car cool down, I see that I was...

Hey Fanatics! After a long time I decided to fix my leaky doors on my sedan. I installed brand new Vapor Barriers on my front two doors, and cleaned the door drains. According to my friend who is a Technician at the local stealership; the design of the door on the E46 allows for water to enter...

For a while I've had a code for this, and finally got around to checking last night when the car was up on the hoist. I was quite upset, but couldn't stop laughing at what was considered a 'small' leak. I was expecting a pinhole or crack in the hose somewhere, instead I find this. The fitting...

Hi Guys ... here is my problem. I had at first a small leak, then it got worse, and eventually I was filling up 1.5l of water before I drive anywhere, usually short trips. At first it was hard to see where the leak was but as it got worse, I eventually found it and showed it to my mechanic...

Introduction: * I have 2004 330i and I love it. I do my research on it if something happens, maintain it regularly, and try to keep it in shape as good as financially I can. Its my daily driver. Story: * On 07/22/17 (yesterday) I decided to go to Angeles Crest Hwy (its close-by to me), and...

Hi everyone, Currently having a problem with my 2003 318i, which I've only had for about 2 months. After driving about 1700kms, I generally get a yellow oil light warning and need to top it up by a litre. I am always using 5w-40 LL-01 spec oil for oil change and top ups. To try and fix this...

So I am not the original owner so I have no background on this car, but while removing the intake manifold to repair a coolant leak I found an odd "patch" on the back of the oil filter housing. I have attached pictures with a zoomed in view of the "patch". This area is just below where one of...

Hey guys, My 2001 325i was driving 'fine' til yesterday ('fine' as in i've been driving it with lean codes which I haven't gotten to still). JUST NOW, I took it out to my normal route but heard weird CLANKING noises under the hood while driving. It sounded as if a metal pole was loose under my...

Soo yesterday i got home late andi saw a baby puddle from the center of my car and it didnt look like oil and didnt really smell like coolant soo i took a video hoping you guys can enlighten me on the situation , it may of happened once before but im not sure. It is directly above the trans oil...

Hello, folks! Newbie here to the e46 forum, but anyway about a week ago I was replacing the jet sucking pump on my 2002 330Ci because of a vacuum leak I determined on a smoke test. I got the dreaded lean codes P0171 P0174 (Plus the thing broke on a very small tug.) Anywho, while I was taking...

2002 325i Just got this car. Coolant was low in the expansion tank. I filled it up, ran the car with heater. Filled it up again. When I stopped the second time, there was coolant steaming/spitting out of the top of the connection where the upper radiator hose connects to the radiator and the...

Hi, I have a 2002 325i and I noticed some oil dripping onto a hose into the engine. I opened the oil cap and noticed some black sludge on it. I drove the car and then opened the cap again and this time white smoke came out and it smelled really bad like it was burning. I just had the head...

Hey guys, I have a nice coolant leak that's playing hide and seek with me. I've narrowed it down from the mid to the top of the engine somewhere under the intake manifold. I'm thinking its the heater o rings, as the coolant puddles on the block. Is there anything else I could have missed? It...

Recently, got my Crankcase Vent Valve and Valve Cover Gasket changed as preventive maintenance. Was under the car today and found this mysterious leak on the left/driver side of the car. I couldn't discern the color and viscosity of the liquid unfortunately. Two pictures attached: 1. Picture...
