I have an issue with a chevy venture with a 3.4L engine with 144000
Light came on after an oil change after warming it up.
Dealer checked it, said 0 PSI at idle.
Car sat for a month.
Changed oil with Lucas after a recommendation.
Light still came on after warming up.
Ran car and raced the accelerator having a gear head friend listening,
Changed pressure switch.
Got car washed, which was done after the above 2 oil changes.
When turning the wheel with the car in gear, light started BARELY
Drove the car to the same gearhead, listened and raced the engine, no
No light since.
Have not lost any oil or antifreeze (manifold gaskets were changed at
135000 with GOOD gaskets).
First dealer said they tapped into the block to check pressure,
bypassing the pressure switch when they stated 0 PSI.
Questions - did Lucas fix it, or was it the switch, or did the Dealer
lie and not check it?
No overheats, no loss of oil, no noise.
Confused - Ideas? thanks in advance!!!!
