Coolant leaks in to one cylinder through head gasket. A small leak, add coolant.

(1998 BMW 323i)
in Laguna Niguel, CA on October 16, 2013
can this be repaired without replacing head gasket and retooling one cylinder? Value of car seems to be close to cost of replacing gasket. Is their a effective and less costly fix?

Check out a product called Blue Devil. That is all i can tell you about it.

I just looked and youtube has a couple videos on this Blue Devil, one says it's junk, the other says best stuff ever! You decide. Of course you know what a mechanic is going to tell you to do, as we have never seen "miracle in a can"! I can't say one way or the other. However i do understand your predicament!

Thanks for your reply. Amazing the car is worth so little when its in mint condition except for the small coolant leaking .

I agree! These European cars are sharp rides i admit that but when it comes to the cost of repairs and durability, i think they are way overrated!

I have the same issue I have a 98 323is and it loses like 16oz of coolant a week and it isn't leaking anywhere that I see so I think it must be the head or head gasket because it did over heat a few mo ago and I had to put a water pump and thermostat in it. I tryed the small bottle of blue devil it seemed to work but after 2wks it was low again and it is fouling the plug to in that cylinder I replaced the plugs right after the blue devil but a week after doing that it is hard to start on the very first start up each day but after it is held to like 1500rpm for a few sec it clears right up and runs fine. Iam going to try the bigger bottle of blue devil and give that a try the worst case is it don't work but that stuff comes with a money back guarantee so I need to fig that out. I will try it this week and let u guys know how it did the YouTube vids show that stuff being amazing but only on cars that are overheating and mine don't overheat it just looses a lilbit of coolant so it might not be getting to the right spot??? If any one knows anything.g about this please let me k.ow I'm also buying a 98 323I convert this month I pick it up on the 1st so I can use my car for parts at the least if blue devil don't work. Thanks sorry so long lol
