- There's nothing more frustrating than suddenly losing oil pressure in your vehicle. What causes this? Can I fix it? I found myself asking these same questions. But this is actually not a difficult repair, if you don't mind making a slight modification to your oil pump pick up tube. If this ol' redneck can do it, you can too. Thanks for watchin', ya'll have a goodun'!

I started out working at a local motorcycle dealership when I was in high school. Just entry level stuff, washing nasty atvs, cleaning around the shop, and assembling new atvs and motorcycles. and gradually worked my way up as I gained experience. Been doing it for 30 years now, still learn new things all time.
I'm following the journey aswell 😊
No wind noise, no phones ringing, nothing to distract me from understanding your entire video. Thanks for a well made video. It may be of use to me with my Zero oil pressure reading.
Five videos later- yours explains it best, 10 minutes faster than some of those that didn’t even solve the problem.
Thank you, quick, to the point and great improvisation!
Ahhhh, another heroic shade-tree fix!!!! My auto machinist and I often assert that if auto manufacturers hired only engineers with dirty fingernails who had verifiable hands-on experience repairing cars, we wouldn't see nearly so many situations like you faced here. Way to go, man!!
I bought new 2004 GMC Denali w/ 6.0L. The oil pump failed the first year. It took the dealership a week repair it. They had remove front end. I have used only synthetic oil since first change & never had any issues with truck w/ 150k. Thank you for showing the reason why this failed 10 years ago under warranty. Never seen oil pump fail so early. This should have been recalled by GM.
Great video! I really appreciate the visual aids you made to explain how to fix this issue. I don't remember any other video (and I use them a lot!) on TH-cam that the videographer went through so much effort to explain the fix. Simply terrific! Thank you D-Ray...it's much appreciated.
Still getting mileage outta this video nine years later. That’s how you know it was worth making the video. Good stuff
I've never heard it explained like this before. I've learned so much from this video and you put so much time into this. Thank you.
Hey, anybody that is sceptical of this info, don"t be. I had the same problem with my 99 2500 6.0 and fixed it myself saving several hundred dollars. Evryone I talked to about it acted like I was nuts, but I can tell you 1st hand , hey, it works ! Great big " thank you" to D-Ray for posting this.
great video! the PVC example was awesome. I'll be doing it this weekend.
You're a good mechanic. You actually think about what you're doing
I am new to being a home auto mechanic. This was really inspirational and I so enjoy and admire D-Ray Smith for taking the time to make a video for us. Thank you!
DrJOR
i will say this video saved me a lot of time. i did this fix so i didnt have to drop 4x4 or pull motor up and it worked great. very impressive. thank you. this was done 4 months ago to my 05 tahoe 5.3 and still working great and now im having to do it to my 05 silverado.
You perfectly described the problem I was experiencing with my 2002 Chevy Tahoe with about 213k miles. I had a local mechanic make the repair. That. Was about 3000 miles ago and it definitely solved the problem. Thank you for the video, it gave me the confidence to have the repair done. I couldn't be happier!
Shawn Raper replacing the pump fixed your problem?
Yes, absolutely. I have put another 4 or 5000 miles on it since the new oil pump. No problems since.
Thank you for the information as well as all the extra work producing the PVC display parts, Well done Sir
I ran in to this problem today, thanks to your video I have and idea of what the problem may be, is great knowing some people out there is kind enough to show how to fix car issues.
That is an excellent tip and your pvc prop worked very well. This will save somebody a lot of time or money. Nicely done!
"Kinda under .the gun and not very camera friendly at the time" That is a great description and one I can so much personally relate to. Thank you very much for taking the time to put this video together! Excellent info, hopefully I don't have to revisit this for my 2003 5.3.
thank you very much for the info. my 2005 Silverado 5.3 had low oil pressure when it was cold at idle. pretty sure it was just the o-ring but I changed the oil pump while I was in there. the trick you showed about how to get the bolt out of the pickup tube and use the drimel to turn the hold down was a life saver!!! thanks again
all these things I learn about newer trucks make me appreciate my older trucks.
Awesome trick on the pick up tube. I recently had the same issue but jumped right in to the oil pan and cleaned about 3/4 of an inch of sludge from the pan, replaced the pick up tube oring and all. Now I'm changing the oil pump and really didn't want to take the whole front end back apart just for one darn bolt.
You just saved me hours of heartache and frustration, Thank you!
this very thing happened to me today, after listing to a few people your video was down to the point and easily explained.nice job.and thank you most of these guys on here will give you a migrain
This video is spot on. It is exactly how he explained it. I just replaced my oil pump and did exactly what I learned here. Thank you very much you saved me a lot of trouble. Also cut the little piece off to turn the flap around. This is by far the best and easiest explanation. Thanks again sir.
you're ability to create a replica like this is pretty awesome. I'm impressed
I've never run into this problem but it's good info to know. This video could save someone a pile of time and money. Thanks for taking the time to replicate what you you did to fix this the easy way.
Simply, you are very easy to listen to... Easy to understand what you are explaining... Keep up the good work.. Al at Easy-Run Engine Test Stands
Thanks!
i agree easy to follow and pvc pickup made it clear .
You did a great job on this fix no music no distractions just informing us on your wisdom well done sir thank you for your video
Thanks for the kind words! The pickup tube does have other mount hardware, but you can flex it around a little bit to help remove and replace the oil pump body.
I have a 2008 Chevy Silverado 5.3 Liter truck and got the
P0521 code recently. The error said that the oil pressure was low, but the
engine sounded fine. The gauge read about 20. I checked and verified that the
oil level was good. I had about 10% left before the oil needed changing
according to the display. After much research I found that most pointed to
debris in the small filter underneath the oil pressure sensor. Most people
replaced the filter as well as the sensor. I also found one post in which it
was said to add a little transmission fluid in with the oil. After research I
found that this acts as a flush to the engine. I added about 1/2 quart of
transmission fluid to my oil, ran the engine for about 10 minutes, drained and
replaced the oil. I used a free app called Torque to clear the code. After
doing this the oil gauge went back to normal which is near 40. This is my
experience, but I encourage you to do your own research and proceed with
caution. A couple days have past and everything is still working normally.Hope this helps someone.
Man I wish this was here a few years ago, or I at least seen it. My 2011 gmc Sierra 4x4 did kinda the same, I was driving down Hwy at 65 mph and oil fell to 0 and gauges started go nuts. So I pulled over and checked the oil and it was fine, scratch my head a little and got back in and fired it back up and it went up a little but not back to 40 psi as it was. So I turned back around and headed Back home as I was only 1 to two miles away and pressure started falling again, but I made it home. Long story short never no noise not even a tap, I change oil, sending unit with screen and all I was able to get was good cold pressure but warming it was dropping back down, so I traded it in and I loved that freaking truck. By the way I even drove it to dealer which is about 30 minutes away but hardly showed any pressure when I got there. Wish I knew what it was, some engine warehouse told me gm had a bad batch of cams around that year
I'm having the same issue set reminder 2010 with no oil pressure gauge the code is on there but won't go off I figured it would go off by itself once I fix did you have to buy that thing to get the code to go off
I have read this symptom in several forums before. Sounds like your oil pressure relief valve is hanging open (like mine did) but it doesnt stay hung. reving the engine or restarting it sometimes jars it loose and your pressure returns. I see a new oil pump in your future. Best of luck to ya.
Thanks for the video and tips. I just performed this entire job in under 4 hours, now I have oil pressure. The hemostats worked amazingly well, I even used them on the two bolts holding the pan onto the front cover. Another tool added to my toolbox.
Done mechanic for 50 yrs still do. This is about the best explained and the most useful since
just about every GMC, Chevrolet, or just Chevy light truck...maybe a car here and there uses this design and experiencing LOOOOW FOR ME TO TAKE TIME TO DO A COMMENT..
mine ended up being the bolts on the bypass side of the oil pump. they were backed completely out. but i replaced everything and did it exactly this way! except i used fishing line on the bolt for when it drops in the pan :D
worked awesome!
Alex Berry Cool!
Alex Berry using fishing line is a great idea
Great video! Nice explanation - thanks for the help. I think this is the same problem I'm chasing on my 3/4 ton.
D-Ray, thanks a TON for this video! I have watched it many times and feel confident I can now replace my oil pump by myself! I’ll let you know how it goes.
Thank you for this video. When I first watched it I said "ahh hell no, ain't nobody got time for that..." then I came crawling back when I decided to rip it apart myself. Truck is purring like a kitten now after a sudden complete loss of oil pressure and replacing the oil pump. Thank you so much for your clear explanation on how to dremel that nub off.
I’m glad I watched your video 6 months ago cause everyone I talked to said it can’t be done without removing the pan. Thank you.
I Just successful replaced the oil pump like this except I got the bolt back in the same hole. It was a bitch though. I ended up walking the bolt back to the hole with a pair of curved needle nose pliers. Looking at the front of the engine, I had to enter at the right bottom side of the oil
pump then go left to the hole on the pickup tube. Then when the bolt was right at the hole, I used a standard screw driver in my other hand and picked up on the bottom of the bolt to keep it in the hole. Then I started threading the bolt back in using the needle nose pliers and finally tightened back with the wrench.
The reason I did it that way was my pickup tube clamp was brazed on. You will drop the bolt on the first attempt but a good bore scope with a magnet tip will get it right out so you can try again. I dropped it 3 times but total time took about 10 minutes to get back in.
Also great description on the oil pump pressure valve. Sure enough, the one I did was stick open. I touched it with a pick and it snapped shut.
This was on a 6.0 GM with an Allison Transmission in a freightliner step van.
Very usefull info. Ive got 2 5.3 engines that suffered from this dropped oil pressure... i got them very cheap for that fact but i will make sure to incorporate your mod on the rebuilds.
Thank You !
Had a similar problem about seven years ago with suddenly disappearing oil pressure in my 2003 Z71 Tahoe at about 125,000 miles. My son was driving it on the Interstate out of town when the engine stopped at the bottom of an exit ramp; he had the low oil pressure messages and lights, etc. and to be safe we had it towed to the Chevy dealer in that area. The cure - $1,500 worth of new, installed oil pump. Wish I had known then what you taught me in this video. On the other hand, my son is still driving that same vehicle every day and it now has over 250,000 miles. The low oil pressure incident has been the only engine problem we’ve ever had with that vehicle, which is amazing, since we have worn out one rear axle and numerous non-engine parts over the years.
D-Ray, you are a genius for finding the “Plan B” solutions to these myriad problems caused by poor GM engineering and quality control.
D Ray Smith, thanks for making this video and taking the time to figure this solution out. Very resourceful and to avoid dropping the differential it’s sure worth a look !
Great video, well informative and good narration. Two thumbs up.
Great video, I can easily see this making my year if I needed it. thanks for the information and I hope I never have to use it
Excellent Video! Good Fix. In looking at online information about such a common problem with General Motors low engine oil pressure, I can't believe how many garbage stories and time wasting suggestions are available. So far, your video is the only one that I found that explains the real problem and the fix. Great Job, thank you.
Thank you very much! The time you have taken to explain and show us this information has helped us out hugely!!
Great video and technique to avoid a lot of extra work. One suggestion ... instead of cutting the top of the retaining tab, make the cut at the bottom. This allows you to rotate the bolt flange, but also allows the tab to still keep the tube from rotating.
This is the comment I was hoping to find somewhere! Cause I'm like.....well the tube can flop all around now.....probably not good! Bout to have an oil pump inspection myself now! Bout guarantee my problem is this problem
Yea but does the flange have that groove on both sides of it to slide it up
Thanks for watchin' my video, I hope it helps ya'll with your project. The way I installed the new pump was to disassemble it just like I removed the old one, and install only the pump body first, and leave the attaching bolts loose to allow you to install the gears. I coated the gears with lucas oil treatment prior to install so they would seal and pick up oil pretty much after start up. And I reused my crankshaft bolt. Have a goodun'!
I had the same on my 2005 2500 hd. I also watch a truck load of videos. Your was the best. I no long have any problems of tackling this job. I will keep you in my favorites . Great job. Thanks
Thanks Dibber, I hope it helps other folks, as this is a pretty common problem. Have a goodun' bro!
Best info on TH-cam on how to do these nightmare oil pumps!
For that my friend
You get 2👍👍
and a 12pk
🍺🍺🍺🍺🍺🍺🍺🍺🍺🍺🍺🍺
Thanks a Bunch.
Hay D-Ray Smith...
Outstanding on the mod sir, I hope to use this in the future. P.S. There is still some good guys out there, Thanks Again.. GDH.
Gary Huneycutt Thanks!
@@DRaysShop I have a 2008 Chevy Tahoe what a bad sending have drove it 3 days with no oil pressure and not making no noise will it hurt my truck to drive it with bad sending unit
I don't know is if this is my problem or not yet, but thanks for being awesome and trying to help people at home. Wouldn't hesitate to give you business if I was ever in the area. Keep being great.
Outstanding video. You are among very few who get right to it. Clear and understandable. Very much appreciated. Thanks
I don't know if the valve is replaceable, but due to the large number of failures with the oem pump, I went with a melling pump. The design of the valve is different, and I have yet to hear of any problems with them.
Very interesting, I had problems with my 5.3 in a 2000 silverado 1500 4wd. I had 225,000 on it so I didn't dig into it. Had 20 to 25 psi on the highway but oil light was on at every stop light. Bought a salvage yard motor with 107,000 on it for $500 when I started having the problem and just drove the old one til it dropped. Ran for about a year that way but ran into problems during a January cold snap. Up here in ND it can get cold, got to -25 and would build very little pressure. Dropped a rod out the bottom of the pan, time for the other motor. Replaced the suction o ring before I put it in, there was some sludge in the pan. I have heard these motors can buildup with sludge. Cleaned it out, put in mobile 1 high mileage oil and it has good oil pressure and is nice and quiet. The old motor was always prone to lifter noise when it was fairly new.
Thank you DRay for the video on the issue of the oil pick up tube problem. I have a 2005 with the 5.3 with the same issue and this is great info. I appreciate it! !!
Hello, this video was a home run for me. I replaced the oil pump on my 2005 Silverado and modified the the flange on the pick up tube just like you did in the video. Thank You and God Bless!!!
be sure and note the orientation of the pickup tube FIRST. It is now subject to movement with the lock tab removed.
can you elaborate? I'm about to do this job on my '14 sierra 4x4.
My tube is in the way and seemingly is preventing me from pulling the oil pump off of the crank....should I use moderate downward force to get the tube out of the oil pump??
GM and their infinite wisdom...lmao!! my solution for the engineers would be to have them work on such as they design,in the real world...like we have to do.then,i think,they wouldve put that lil 10mm in the top hole..
great video hoss,i enjoyed it!
No, the engineers would still put it in the bottom hole . they don't want you to work on it . They want you to take it to the Dealer and charge you $95/hr.
First video I have seen of yours and I must say very well done. Great PVC mockup and explanation on the fix for this problem. I'm sure that you will save MANY people a lot of hard earned money. I can't wait to see the rest of your videos.
This is a perfect example of why "Old Guys Rule" Thanks Brother!
💖💪😎👍🇺🇲
Told my ex wife the same thing once lol
This hole or that hole it's all the same thing 🤣
Dead
Dumb enough to get married eh
My truck is at around 40 when I'm on the freeway then at idle, like at a stoplight, the alarm will kick on and my lifters start making noise. Revving the engine to 2-3,000 rpm restores the oil pressure. So for a permanent fix, it looks like I'll be crawling under my pickup and cursing at it here in the near future!
+Jon Moore been there, done that. And we did drop the whole front end! What a nightmare!
I actually took it in. $375 well spent it sounds like!
+DBAspen2011 just a little independent shop.
Your video is THE BEST showing this operation. To make sure you don't lose that bolt on the pick up tube...tie a string on it after you back it out some. Tried and true. This method came from a 69 year old guy to keep from pulling the engine and removing the oil pan. Extra safety. Great video.
Hands down best, most informative, thorough and simple to understand how to I ever watched. I'm a visual person. That's why I watch and learn from TH-cam. Most how to just explain it with camera on their dumbass instead of the parts or process. Thank you.
GM lack of common sense is the culprit to begin with. On-going engineering improvement during production runs is alien to these people. After the problem is known they continue to do the same thing over and over. I realize no one is perfect but this kiind of thing is why they have engineering and development departments. Ford is similar and so is Dodge in their stubborn approach to problems. Much more testing should be done prior to the first build.
A Day GM doesn't think about failure. They think about assembly lines and Manufacturing. But overall it's an easy truck to work on compared to other cars I'm working on
Seems so weird that they wouldn't do improvements during production. When I was working at Caterpillar they were making improvements and changes to the process daily. It was agrivating for me because I was logistics and parts were constantly changing, but the customers loved it and that is what matters in the end.
Ahh shit I'll just drop the pan man. Very innovative though.
not on a 4x4 you wont
I have no questions at the moment..But I like the way you explain pretty straight forward
You are by the best that really showed the problem and the best fix. I wasted about $300 on unnecessary fixes.
Thanks, just tryin' to save a lil $, lol
All it takes is a little nick in a 10cent rubber ring to blow up a $15k vehicle.
yep, and GM will go cheap on the part just to blow up that 50k vehicle.
I agree, new GM full-size, fully loaded vehicles run from $50-100,000 now
24 Dec started my 07 truck. lifters loud and warning of no oil pressure and shut engine down. found other videos pointing to the pump. All looked like a nightmare until i found this one. Thanks so much for sharing this and spending your time. Wish i had a gauge.
D Ray! Thanks so much. You saved my butt. Awesome video. I thought I was going to have to tear my truck apart. Still a pain but you really help save me. Thanks again.
lol you aint got no damn oil pressure fool
Wow sir, I appreciate you sharing your knowledge of this oil pump psv and oil inlet tube seal problem. This was one of the best videos I have found. Great job, God Bless you.
Very well covered, and made the instructions as simple as possible.Heck of a nice guy too!
Huge respect for your clear presentation of a problem and determining its solution....you must be one of them rocket surgeons! Thanks for the info you saved me $!
wow, finally found the guy that explains my intermittent oil pump problem. 2004 8100 on a Workhorse chassis, Safari Trek Rv . .
looks like im dropping the pan and replacing in pump . 90k plus miles,
2 nd owner.
saved me taking it to GMC at 150 bucks an hour!
I was glad to see your video ,. My pressure relief valve has stuck,. JUST LIKE YOU SHOWED. No one but you have diagnosed this to be the problem,. I went down 10 lbs all of a sudden,.From 40 to 30 at idle ,. Called by dealer service guy he didn't know what I was trying to explain ,. Thank you for confirming my diagnosis. Chevy man
this is a perfect explanation ...I have a neighbor with a 2014 with a 5.3 vortec with sudden oil pressure loss...I am going to do the repair now that I have seen your video....thanks so much for taking the time to make this video...I would not have takin on this job without seeing your video...great job and thanks from a fellow gear head...even tho I am up in Canada
I don't own one of these vehicles, but I found your video so informative I had to reply and let you know how good it was. Great work man.
One of the best made videos I've ever seen. Excellent job. Good on you sir.
Wanted to say thank you for the very informative technique I'm in the middle of replacing my oil pump and am very grateful for your video
Thanks Jeff, I appreciate it bro, especially comin' from a fellow gearhead. Have a goodun'!
Brilliant! My 5.3 isn't down to 0 yet but has dropped to about 20 psi. Pressure bypass hanging up makes perfect sense. Changing the bolt location is genius!!!
GREAT work-a-round, I just went thru a similar problem, mechanic wanted to charge me 1200 to do a pump job. Turned out to be the belt two pulleys that were making noise. Took $60 bucks and 1/2 hour to fix. Mech swore it was the pump making the noise. Guess the mortgage payment was due this week!!!
It's now the year 2020! I have experienced what happened to you. Wow, your video was right on the money! Lucky me, I found your video among the many. Your video was exact what I had to do, even the vehicle except newer truck.(2017 Sierra 2500) Thank you for your time to share and teach the rest of us!
great work D-Ray, you're an automotive saint.
Thanks for taking the time to make this great video. I wish I had found it before I dropped the engine in the truck!
Thanks for the kind words man. I do appreciate it.
Thanks worked great took me 5 hours with running around to get stuff but could do it now in 3 hours or so. Very pleased on getting it done without dropping oil pan! I've seen pictures of the whole front end dropped out of the truck to get the job done. Great Info!!
D-Ray, I have been very frustrated my our 2007 GMC Yukon 6.0L. Changed the oil sender (twice), then put on a new oil pump. AGAIN, the oil pressure goes to near 0 and the warning light/tone comes on (BTW, still had 'some' oil pressure and engine did not make noise or overheat). However, once the engine warms up, you can get back in it and drive without issues...until once again it totally cools off. Based on the slow but deliberate loss of oil pressure I believe your theory on the spring/bypass valve is what is happening. Great breakdown and you were very clear on your words. Thank you very much brother.
You're quite welcome! I do my own repairs by simply google searching the problems.... each vehicle has their own inherent characteristics, and it's guys like you that save me money on labor!
Found and ordered the Melling M295 Oil Pump at Amazon for $64.99 + $8.25 shipping for $73.24 total.
Awesome video. Great delivery and thank you for the mock up.I got an 07 4x4 classic and it this ever happens I'll be thanking you from Texas.
The curved hemostats was brilliant!!! I have always used my index finger behind the pump, and a small screwdriver on the opposite side. I will be using the hemostats when I do the next pump removal!
D ray, you should be given a noble prize genius.
Good video! Oil pump seems to have gone out on my 2002 Suburban. So I’ll be prepping to that job in a few weeks. This is a good start to show the oil pump assembly. Good job and thanks!
Good thinking fella. Very efficient solution to the very common pressure loss issue that I know the 6.0 has been notorious for, especially when they got up to higher mileage. Thanks for the tip.
Great video of a fairly skilled craftsmen at work. The art of the work around is what the pros are looking for.
Thanks for sharing your American craftsmenship.
All the best.
This explained a lot of what happened to me yesterday. I was in a rush and hammered down to pass a car right after I lost all oil pressure and was definitely some knocking. I parked it and was concerned that I did some serious damage but had just figured I had taken care of the aluminum head problem leaking coolent. Started the truck up this afternoon and had oil pressure again but still did some wearing on the motor. And just couldn't understand why I had lost pressure and I believe that the oil pressure blow by did it as I ran it hard never even knew they built that in to the pump. Great video easy to follow for this shady tree mechanic
Thank you for posting this video as it helped me and a friend from a spendy shop bill.
