Nope prob leaking freeze plug
can a knock sensor leak oil for 305
When a water pump is bad it will leak. There is a hole in the pump were water will leak out of.
Yes it will leak out of the hole that the sensor is screewed into.
Only if if has a leak.
The knock sensor is exactly what it says. It senses any knock or ticking in the engine and retards the timing. The knock sensor is not the problem, the knocking is. Go to a repair shop and have it diagnosed.
You either have a bad oxygen sensor or a vacuum leak. Code P1133 indicates a faulty heated oxygen sensor but a vacuum leak could also cause this code.
No it shouldn't, There is a sensor that turns off the gas if the pilot flame goes out, The only way it would leak gas is if it as a faulty sensor, or a peice of depree gets in the gas line
vacuum leak/intake leak,dirty/clogged injectors/dirty/faulty mass air sensor.
Could be several reasons such as a large vacuum leak, a faulty EGR (Exhaust Gas Reclaimer) valve, a faulty MAF (Mass Air Flow) sensor,
It means that the bank #1 O2 sensor, the bank closest to the firewall, cylinders 1-3 is showing a lean mixture. Could be a vacuum leak, a misfire on that bank, an exaust leak upstream of the O2 sensor, fuel control or injector problem on that bank, a faulty O2 sensor, faulty PCM, faulty wiring in the engine control wiring harness, and there may be some more possibilties I haven't thought of yet.
Make SURE the engine is COLD. Then unscrew the old sensor and install the new one. Antifreeze will leak out of the engine so be quit when replacing it.
too lean at higher load - Leaking fuel injector or pressure regulator - High fuel pressure condition - Faulty front HO2S - Leak in exhaust system - MAF sensor faulty
