flashing oil light and lumpy revs

Hi Guys. Please help a damsel in distress!!
I recently used steal seal and white shepherd leak seal on my bmw 316es compact as was advised by a friend. The symptoms were lumpy revs occasionally, misfire in cylinder 3, wet in cylinder 3, white smoke on start up that disappeared after 10 mins. i used the steel seal and leak seal and it was great for a whole day. This morning i started it and no power, i put my foot down and it stalled. If i turned the engine off then on but with my foot full on, it revs high and falls to 700 then fluctuated between 700 - 1200rpm. I can also hear a intermittent gurgling noise inside the cab from behind the dash which goes when i turn the heating off. Any ideas would be greatly appreciated

Blown head gasket and most likely warped the head by now is what it sounds like. White smoke is never good, check the oil, if it looks like chocolate milk coolant got into the oil and the car is a paper weight.

Hi. Thanks for reply. There's no cream cheeses etc in the oil. It's very strange. It isn't overheating either. I did hear a high pitch squeal like a slipping belt or something. Any thoughts?

You probably have a check engine light on. Get the codes and post them here for us.


p.s. Bars leak is the best head gasket temp sealer. Never even heard of the other stuff you mentioned.
