Chevrolet - Blazer :: Oil Pressure Dropped To Zero While Driving At Highway
Jun 5, 2016
I have a 1999 Chevy Blazer LS 4WD 95K miles that had an incident in 2008 where the oil pressure dropped to zero while driving down the highway. I immediately pulled over and had the vehicle towed to a dealership. They pulled the oil pan off and let me know the lower part of the motor was "toast." (crankshaft had turned blue due to heat from no oil.) Mysteriously it has oil pressure now, why that is. It started last time I tried about 4 years ago.
I dearly loved this vehicle. It was first car I bought and paid for myself and I planned on repairing it one day. It's been sitting in My garage for the last 8 years. Recently, my daily driver died and I was faced with repairing the Blazer or buying a new vehicle. Since I don't know how well the Blazer has fared sitting in the garage all these years, I decided repair wasn't worth it at this time for a vehicle I needed to be dependable and I just bought a new vehicle.
So here's the thing. I kept the Blazer really clean. Washed it all the time, no damage, Regular oil changes, the works. It still smells like a new car inside. I really don't want to see it get crushed and I'd like to see it go to a good home. It might need more work than a new motor since it's been sitting so long, but I can't imagine it would be more than someone mechanically inclined could handle. I'd get a new engine, but I don't have the cash and I need the garage space.

Okay....I have an 01 blazer 6 cylinder 4.3. For a while it was missing fairly bad until I had the distributor replaced and the problem went away for about 2 months. Now it seems to have the same problem again so I am wondering if that wasn't the real problem. Here is what is going on. The tac needle bounces and it feels like the engine is misfiring. When I am driving on the highway sometimes the CEL starts flashing. Sometimes it stops and sometimes it doesn't. Plus now it feels like when it changes gears it's lurching. It only does that sometimes. The odd part is there seems to be no distinguishable pattern to the lurching. I think the misfire could be just the timing needs to be adjusted.

1997 chevy balzer 4.3 6cyc. Oil pressure drop from 40 to 10 and making a knocking sound no loss in power. About 3 weeks ago had oil change and new oil lines and gaskets put on because i had some leaks no noise or problems then just was losing oil then this happened first of all does this sound like a main bearing gave away second should i go back to where i had this work done and complain could they have done something to cause this they are very good and honest mechanics and a reliable auto repair mechanic company the blazer has 180,000 miles or do you think it just because of the mileage it was bound to happen i hate to blame something on someone if was just a coincidence but does this sound like the main bearing?

My 4WD light does not come on but the warning light to service it does which leads me to believe the 2WD is not engaged. I have a 2001 Chevy Blazer. Also the seems to be a "rubbing" noise emanating from the right from while driving.

Driving down the road, vehicle lost all electrical power and died. There doesn't appear to be any juice at all to start it. The battery is fine (along with the terminals), the starter is okay too (although I don't see why that would affect total electrical flow). There were not any alarms on the vehicle. Is it the fuse box (negative terminal) or possibly the alternator? The alternator had been charging, and the battery showed that it had juice left in it. What would cause the vehicle to just die like that, in the middle of driving it? It's an LS type blazer with a 4.3 L engine.

My husband has a 2009 Chevy Aveo, he's had several issues lately, split radiator hoses, an oil pan issue and now he says it's decelerating when he's driving on the highway, the engine doesn't rev when he presses the gas pedal, we can't afford a new car but he's afraid to drive an iffy car through the winter on a somewhat long commute?

I was driving down the highway when I lost all oil pressure soon after I lost power steering and the engine died. I have checked the radiator and it is still full of fluid pulled the starter off and try to crank it it still turns the cannot get the engine to turn over it clicks but wont turn over there are no oil leaks underneath the vehicle that I can see. I'm just not sure where to go or what to do from here

I have a '99 Chevy 2500 diesel truck. After driving it at highway speeds for more than 20 minutes and turning it off, it won't restart. The problem seems to be in the battery cable and is definitely heat-related. In cold weather or after a fairly short drive, all it takes is popping the hood to cool off the engine compartment, and waiting. If the engine and/or the weather is too hot, that can take an hour. Then it starts just fine. I've cleaned the terminals and made sure the connections are tight. Two mechanics have looked at it and were stumped.

My father passed down his 1973 Chevy C-10 pickup truck to me and my family. It's been our 'runner' truck for many years going to the mountains for wood, lumber from the store, garbage and yard debris...etc. Unfortunately, it recently has been starting and warming up just fine, but once it's running as I'm driving away from stops or even holding speed on the highway the power 'fades' from the engine and it lugs like it is in gear, but flooded and lurches as the engine seems to 'catch up'. I have replaced the carb(holly quadrajet), fuel pump, fuel filters, battery, fuel lines, throttle cable, distributor cap (ceramic piece too), alternator and more...we still can't get it figured out. NOW the truck won't start or turn over - have we reached the end of it's life no matter what we do? What is left to replace? I don't think we can afford much more $ to fix it. We also found that somehow water was in the gas tank, which we think was from a kid in the neighborhood messing around. Could that have made a permanent issue?

'98 Chevy Lumina. Driving at Highway speed, I hear a short rattle. Makes me think of linkages vibrating, from the passenger area. Few minutes later I hear it again. Few minutes later I look down to see me thermostat at 240+. I watch it redline, hold for a few minutes, then the rattle again and my temp goes down to 160 or so. All of this happens at 60 mph, in 45 degree weather.
Rinse, repeat about every 10-15 minutes. I notice that while the engine temp is climbing, I have no hot air from the vents and after the rattle and temp drop I do have hot air. Check the block when I get home and I see the familiar green puddles. So is this: Water pump, the apparent source of the leaks, heater core causing back pressure to leak at the hose, or the ever dreaded head gasket?

I have a 1986 Chevrolet El Camino with a small V-8 engine. The vehicle has 150,000 miles on it. It starts and runs fine. It does not use oil. My problem is the oil pressure. After the car runs for a short time, the oil pressure starts dropping. It will drop all the way to 0 if I let it. I have had the sending unit replaced and it did not work.
I have had two mechanics look at it and they have not been able to solve the problem. One checked it with a mechanical gauge and confirmed the low pressure. He suggested a higher weight oil and an additive. The other mechanic's solution was to raise the idle speed. I have had this vehicle since it was new and always kept the oil changed and all other maintenance done. I would like to keep the vehicle and complete any repairs necessary.
My question: Is the engine repairable economically or does the engine need to be replaced and what is causing this problem.

2004 1500 5.3 low oil pressure after using Lucas engine stop leak. No pressure at idle just below 40 when driving. Replace the sending unit and pressure improved for about a day. Just had a manual pressure gauge hooked up and it shows the same as cluster. No engine noise at all. I was informed that using Seafoam or another solvent could loosen up build up and cause damage. Trying to find out if using an engine flush machine may support. I am assuming that the cause of the low oil pressure is due to build up from using several qt of the stop leak over a four months. I am the only owner and I have always changed the oil according to schedule and have always used Valvoline synthetic.

My 2004 f 150 heritage 4.6 l the oil pressure dropped all the way down i was in a drive thru and it was clattering really bad so i pulled into the parking lot and shut it down pulled the stick plenty of oil i re started about 30 minutes later and it pumped oil pressure. So I started on my way home the gauge would go to normal and when I would touch the brakes and let off the gas it would drop and the oil light would come on and the engine would start rattling and would have no power, I would pull over and do it over again and finally i just called a tow truck.
So I changed the oil new motorcraft filter and 5/30 motor oil , it started up made all kind of noise but i got oil pressure and quieted down i went to drive it and as soon as it started to roll the pressure dropped and the oil light came on and it started to rattle again. Whats happening is the pump going out ? can it be replaced with out pulling the engine? the truck has 200,000 miles on it

So I'm having some fun issues with my S10 Blazer right now.
1992 S10 Blazer 4x4 4.3L TBI, 4-speed auto (not electronic)
ABS Codes- 41, 42, 46, 51, 52, 65, 67, 68
The speedometer is jumping around sporadically.
Gas mileage has dropped astoundingly. Tank has gotten me 80 miles!!!! Poorest MPG ever!!
Also, may be related, the tranny has shifted properly for awhile. Slips from 4th to 3rd when letting off the gas at highway speed, and won't detente shift 4th to 3rd even with the gas completely floored. I had the tranny rebuilt in November and had the detente cable replaced a couple of weeks ago. I'm going to make sure it was adjusted correctly today by using the shop manual method: shift the cable back and ratchet forward with throttle or gas pedal.
As far as the ABS and speedometer go, I'm going to test what I can with the vehicle speed sensor (VSS) and the DRAC module today. With my WinALDL scan tool, I found it is definitely not a speedometer issue because the speed coming from the computer is fluctuating as well.
There is a test in the shop manual to do, but are there any other tests for the VSS or DRAC module? Reason here is because I replaced the VSS after the tranny rebuild in November. So either the DRAC module is acting up or something in the transfer case is screwed.

Been doing a lot of repair's on our 1994 Chevy blazer. It's a 4.3 v6. We finally got her running and now it seems like it can't take high speeds for very long without over heating and eventually smoking some. Had to bypass heater core, it's clogged. That worked with temp. Also replaced radiator and cap. Replaced both heads, took thermostat out. That worked with temp too. It has a new water pump, new exhaust manifolds, has good spark plugs, oil changed and oil filter. Kind of at a loss.

I have a 96 aerostar with just over 100,000 miles. Recently, after driving about an hour at highway speeds I noticed the oil pressure dropped to zero when I came to a stop in a rest area. I immediately shut the van off and checked the oil, which was full.
After restarting the engine, the oil pressure gauge read normal again so I proceeded on my way down the road keeping a close eye on the gauge. Within minutes the gauge started fluctuating from zero to normal several times and then dropped to zero and stayed there. It sounded like I was getting some top end clacking (may have been my imagination) so I shut off the engine while driving and restarted it and the pressure gauge started reading normal again.
I drove to the next exit and figured it must be the sending unit acting up, so I checked the wiring at the unit for a possible loose connection and finished my 150 mile trip with no further issues with the oil pressure gauge. I have run the van locally on short trips but I am afraid of making any long distance runs without knowing for sure if it was the sending unit or perhaps another more serious problem.

I recently installed a glow shift fuel pressure gauge. All seems good.
@ idle 58-60 psi
@ WOT drops to 50 psi, no less.
Tonight I went to catch up to a car that had no lights on at all to tell them and during WOT fuel pressure gauge showed it dropped to less than 30! I let off immediately and it went right back up. I tried to repeat it with another go @ WOT and it would not go under 50 psi like normal.
Motorcraft fuel filters less than 3000 miles ago .. Blue spring installed over the winter.

Our 2000 blazer LT 4.3L 4 door 4wd has 190,000 km (about 115,000 miles). 3 Button dash control. Transmission was rebuilt at 100,000 miles (main troque converter spline was shot). The 4 wd will not engage in either hi or lo.
Whether moving or not, press 4 wd lo, light stays on. but nothing happens. I cannot hear the transfer case engaging.
Had a previous problem, (withflashing light): found the vacuum hose under battery case was worn through.
I do have a service engine light on the dash. This may be unrelated, because 4wd stopped working long before service engine light came on. I have changed the Oxygen sensor, but no reset the fault yet. Where to start.
