Question about Cars & Trucks
Recently had my blown head gasket fixed on my 2006 pt cruiser now my oil light keep flicker on and off when I'm at a stop light but will stop once I start back driving. Do anyone have a solution to this problem?
There is a possibility that the oil pressure sensor wire located on the engine block is either incorrectly fitted or the wire is off completely and touches an earth (negative) source, causing your warning light to occasionally flicker

This is the pressure light, nothing to do with the oil needing to be being changed, you have low oil pressure being indicated, this will destroy the engine if the light is really indicating low oil pressure, have the oil pressure tested with a mechanical test guage at a shop, if the oil pressure is ok then replace the oil pressure light sending unit.

i really hate to tell you this but it sounds like you all ready know what the worst is! it's all the classic signs of a bad head gasket, caused by over heating, and the head or heads become warped, a classic problem with 4.6 engines if they become to hot to long, not a cheap fix as i believe you know, what i would do is take it to cadillac dealer and let them give you an estimate,its free and get another just for the heck of it. good luck to you, wish i had quick fix but their are none!

There should be an external ground wire from the headlights to the frame, locate the wire and clean the ground and wire teminal.

If i remember right the color of the smoke will tell you what it is and i think blue smoke is water getting into the combustion chamber. The car can run like this for a while. Lots of times the car will run like normal besides the smoke. But the passage in the gasket will continue to get bigger and lead to more serious problems.

Hello, First, you have to clear some of the Codes with a scanner or wait after 25-35 start-ups for the information to cycle out of the system.
Next, make sure you have replaced the correct Bank or lower or upper sensor when there can be 4 sensors on the exhaust.
The wiring running to your sensors may be bad. Also, if anyone has fooled with the wiring to the sensors, some have cooling tubes which are embedded in the wiring. Sometimes people rewire the connectors to fit different O2 sensor plug-ins and the cooling tube is cut. When these plug-ins are manipulated this way the sensors overheat.
I can't say offhand about how your PT cruiser has its wires configured into junction connectors. They may be replaceable junctions or may be moulded into the housing of the O2 control unit as 1 piece.
You will need to ask at an Autoparts store or go to a Salvage yard and try to find a harness you can use. It is not impossible that the sensors you purchased could be bad. You should be able to get some sort of continuity value from the prong connectors on the O2 sensors to see if you have a circuit in the part.
I hope my solution is helpful, perhaps a Chrysler mechanic will answer you.
