Re: [Peugeot-L] O2 Sensor Questions 405S

The reason the dip stick blew out was because the crankcase venting system is
a totally flawed design. In cold weather without modifications you are at risk
of destroying your 8 valve.

Write for detailed modifications and the reasons why your motor will self-destruct
if left to it's druthers

Hello,
In the past years I have seen how malfunction of the O2 sensor can bring on bad running and the CHECK ENGINE light. Once I got it in cold (-10°F) when the oil blew out the dipstick and soaked the sensor. I got it this year after flooding my Mi16 and finally getting it started. Now I think the problem has recurred. Three times after driving in very wet winter storms, after stopping for a short period, the engine will chug along, barely idling, and will clear itself up in twenty or thirty seconds, and of course bring up the self-enrichment fault code. This never happens in dry weather. I read to never get anything on the outside of the sensor, could chemicals dumped on the roads cause problems?
