Blowing some kind of smoke & using excessive amounts of oil??

hello, Can anyone help me please. I have a 525 SE 2003 with 114000km on the clock. It started to blow what I thought was smoke from the exhaust. i took it to my mechanic who said it smells like anti freeze and that the head gasket is maybe blown. So he put in some K-seal which is supposed to magically repair any cooling problem. The thing is that it never used water and the oil was not at all frothy. The K-seal did not work either. When I got my car back the engine light was on. Mechanic said it needed to be 'reset?'. So I told him I needed to go on a 1 hour trip, he said it will be fine. So before I left I checked the oil and ended up putting 2 liters in. Car went well until I got to my destination it started blowing 'smoke' again same as before I took it to the mechanic. Then the warning bell came up and said 'oil compression then check oil levels'. The car also suddenly started running rough. So I went to a garage and got more oil. I put in 1 litre and let it sit for a bit. When I started the car it was still running rough but felt a bit better. I had another hour to get home. So I kept an eye on the gauges, warnings etc. It went fine on the way home just ran a little rough and blew smoke here and there.
Does anyone have any idea what it could be? I came into this forum last night and read up that the symptoms are the same as the CCV problem but when I took it back to the mechanic this morning he put his finger over the dipstick and it was sucking in so he said it can't be that??? I don't want to get ripped off by not having any idea on what it could be and get forced to pay for an engine job I appreciate your help

CCV. Keep searching and reading. And get another mechanic before you hydrolock your engine.

@ s-thetikz...Hi, I thought the smoke looked blueish black but then sometimes it looks greyish and at the mechanics it looked light grey so who knows..K-Seal is a product available here in NZ that supposedly solves cooling system problems. So annoying Is your car still being driven?

@Fudman...hi there..sorry but what is hydrolock? I have had BMW cars for some years and I've been so lucky not to have had any real problems before..

Crank Case Vent Valve--CCV--you need to replace it and the 4 hose's that go with it--keep driving the car and you could ruin the engine--

Hydrolock is when the ignition chamber fills with a liquid instead of a vapor. Vapors (air/fuel) are compressible. Liquids (in this case, oil) are not. As the crankshaft rotates, when the piston cannot reach TDC due to the liquid incompressibility, the engine will seize and/or you will bend a connecting rod. Engine = toast = very large paperweight/doorstop.

Do a search on CCV and related problems. Given your exceptionally high oil consumption and smokey exhaust, a lot of oil is being burned in your combustion chambers. It looks like you are very near the point of hydrolock. I would recommend you STOP driving the car until you can address the problem as the consequences of hydrolock are quite severe.

Thanks everyone I haven't driven the car since I got it home. I will only drive it back to the mechanic on Monday. Everything seems to point to the CCV.
Can the vaccum from the dipstick still be sucking in and the CCV still faulty? That's the only thing that does not match up with all the other faults to say conclusively that it is the CCV..I really appreciate all of your answers thanks

Read these threads and then read them again. http://www.bimmerfest.com/forums/sho...t=ccv+symptoms

http://www.bimmerfest.com/forums/sho...t=ccv+symptoms

There are several tests for CCV functionality and yet none of these tests are definitive. The dipstick test should be done with a manometer. Your other symptoms reflect classic CCV failure symptoms. However, your oil consumption is scary HIGH. That suggests imminent complete failure. Lastly, do you drive your car for short distances when it is cold? That is the classic cause of the effect. Oil vapors do not fully drain back into the sump and instead, condense in the CCV and associated pipes as the mayo.

Probably blocked CCV.
The M54 CCV job is a full-day affair.
Make sure you make note as you go along as there are a gazillion of parts removed for this simple CCV device!

Heavy vaccum at the dipstick can show CCV failure--the valve in the ccv is supposed to limit the amount of vaccum introduced into the crancase--Full CCV failure is shown when there is full vaccum introduced.

Before I changed my CCV it displayed no "classic" symptoms. But, there was a lot of suction at the dipstick; enough to collapse the tubing in the system and make loud rasping sound when the hole was covered. When I got around to replacing it, everything in the system was shot. That was at about 110K.
