I think my oil pump went out but my car was doing fine until I changed the oil pressure sensor & hour later I ended up stranded with no oil pressure the motor started knockin for a few seconds so I turned it off but it never started again I’m hoping that’s just a safety feature my motor only has 104k on it
Hi Tyler... my 2005 Lacrosse with 3800 is in the shop right now. It had a coolant leak at the timing cover repaired - gasket blow-out. That is now fixed, but when it was put back together, I now have low oil pressure light on and a ticking noise at top of engine (not getting oil up there). Any ideas on how a gasket swap on that housing could have screwed up my oil pressure? Thanks!
3800 usually have a little bit of valve train noise but if it's not carrying good oil pressure I would say either the oil pump is bad or it's not sealed up properly allowing it to draw air or lose suction somehow another possibility would be the main bearings are gone can't carry oil pressure if there's nothing to oil although you said it was carrying pressure just fine beforehand I would say it's not sealed up somewhere
My 16 wrangler rubicon has an np241 in it and mine likes to pop out of 4lo into neutral and also the 4wd light comes on and off while driving down the highway long enough to get it hot. Do these have those same plastic shift fork pads?
Hi there.Just stummbled across your channel . Im curious about your 97 firebird with the 3800 V6 . You see i just bought a 2004 Pontiac Grand Prix GTP and wanted to research on the oil pump replacement proceedure .Now there are differences between yours and mine .but the engine's are pretty much the same. But what I wanted to know about your engine is what side of the block is the starter located on?. My car is front wheel drive so the engineers moved the location from the passenger side of the rear wheel drive to the drivers side to accommodate the transaxle on future layouts . Ive researched this Buick design starting back in 1961 .It was known as the fireball . But that was the beginnings of a good dependable reliable engine. So if you could help me out with my question that would be much appreciated. Thanks
U said it stopped carrying oil pressure. Do you mean completely like 0psi? Cause mine was running 60psi in throttle and 50ish idle. Now it's 48 to low 50s in throttle hard an like 42 cruising and drops to like 32 an as low as 28 at idle I'm getting worried. But had to other problem no nose no burning oil what y'all think
It would carry decent oil pressure if you had your foot in the gas but as soon as it came down to an idle and it was warmed up there'd be nothing main bearings end up being washed out can't carry oil pressure if there's nothing to oil
Hey that's pretty cool man you're pretty smart guy.. that's almost as complicated as a transmission.. thank you for sharing in your time bro keep up the good work 👌 that's two things I would like to learn water pump and oil the two things that will destroy your vehicle if they go lol
Yeah I understand that's not the best transfer case but I was able to fix it for just a few dollars and it's what I already had in the truck compared to the cost of the 205 then buying the adapter to make it work possible driveshaft modifications just seem to make a lot more sense to spend less than 10 bucks on some plastic bushings it's no Trail truck just gets used around the house as an old yard dog
The pads on the shift fork was probably the main issue. Mine would randomly try to jump INTO gear going down the road, feels like someone hitting the floor board with a hammer.
the oil pump cover screws should be torqued to 98 INCH pounds not FOOT pounds. Also, you can remove the oil pressure sender and screw in an air fitting instead then pump oil at about 11 psi so you can prime the engine.
@@tremaynemarcel8358 it's not what I say it's what I mean LOL none of that was rehearsed or edited I simply misspoke but I figured if you're smart enough to tear an engine down that far you can probably figure out that I said the wrong thing
@Hotel Prius This comment is so helpful thank you! When the screws torqued down, should I be able to move the gears by hand before install? Thanks again!
This is a GM 3800 series 2 engine there's no way to really prime the pump like you would on a old small block Chevy what I did was put my oil filter on and poured oil down into the pump to fill it and the filter somewhat then put the inspection cover back on you don't want it to be dry metal having the oil filter already full of oil will help a lot
I have a situation where my oil pressure drops off when coming to stops under break load. car runs fine from initial crank up but soon as you drive it a bit and come to your first stop oil pressure falls off and motor stops. Does it consistently too... checked my sensor and it was good so would my culprit actually be the oil pump assembly? Let me bud. I really need this fixed. 1999 firebird 3.8 v6
When i pushed the clutch in it did. stop caring pressure when idling also. I got it back together it's still not carrying a oil pressure after it gets hot. Now I'm thinking it will never cary oil pressure if there's no bearings to oil if I rebuild the engine I will make a video but I think I'm just going to buy a series 3 motor and put all my series 2 stuff on it and if I do that I might make a little video on what needs to be changed to make it work
If your getting knock your main bearings probably gave out, I just had to rebuild my 3800 in my Firebird and 2 bearings were shot. It caused me to have almost no oil pressure at idle and about 5-10 psi during throttle
@@Lou_sassel315 wow time flies. I cant believe that was 5 years ago. Spun or damaged main bearings can be caused by a bad oil pump. They can also be the cause of low or no pressure. 2 way street. My engine locked up a few days later when I started it to move it up under my carport for repairs. I have no idea why I asked this question. Ive been a mechanic for 17 years and never seen an oil pump that knocks..lol. Glad to hear you had better luck with yours and thanks for offering up some help. Happy Wrenching!

Short, clear and to the point. I appreciate you sir.
Is this similar to the 3500
Did this fix the problem of low oil pressure and do you have a video of how to remove it?
Is there a video on how to get it out of the engine bay?
Thank you
Yeah, 98 foot pounds....??? Man I hope one actually does that
Ayo sir do you have a email or something I could reach you at for questions

Wow thanks for clearing that part up.. didn’t know that..

How do I take that cover off?
Basically everything on the front of the engine has to come off
@@tylerlanders9482 I'm trying to take it off my Firebird at the moment. How did you get the CS pulley off?
@@tylerlanders9482 I can't find out how to do it anywhere on the internet. I want to get my car running because I have 1 week until prom.
@@Zanelander th-cam.com/video/jTLIpYR9NOA/w-d-xo.html not the same car but it's the same engine and pulley you need a special tool to get it off there

What were your symptoms that made you know the oil pump was bad?
Wasn't carrying oil pressure. Main bearings ended up being washed out, but it worked for a little while.
I have no oil pressure (10psi) at idle. And it goes to 40-50psi under throttle. Is this a sign of bad pump?
If the high pressure spring and plunger are not put back in would that cause no oil pressure?
Dirty Worm Yes , of course
No way does that torque to 96 foot lbs it will brake before you get that far more like 96 inch lbs = 7 foot lbs
You mean 8 ft/lb someone doesn’t remember their times tables lol
2:02 ! INCH lbs NOT ft lbs--aluminum !!
I was going to say 90 something ftlbs.... you wouldnt even get any where close before u snap all of them
Agreed, the shop manual says torque the pump cover screws to 97 inch pounds. Not foot pounds.
Driver drop?
Yes
WHAT TRANSMISSION IS IT BOLTED TO AND IF ITS A 400 TURBO CAN YOU SHOW ME THE ADAPTER.
To remover this cover do you have to take anything of from the oil pan I removed all the screws and it came lose from the top but not the bottom
Was it ran dry or something? I've never actually heard of an oil pump failure on a 3800
Not that I'm aware of but I'd only had the car a couple months so it's hard to tell
im replacing the timing cover gaskets on a 3800 and was wondering if the oil pump needs to be orientated with the timing marks on the crankshaft
I don't see why it would?
Your blood, sweat, time & money is worth too much to be wasted on that 241; get a 205 & never look back. Just my .02
Yeah I understand that's not the best transfer case but I was able to fix it for just a few dollars and it's what I already had in the truck compared to the cost of the 205 then buying the adapter to make it work possible driveshaft modifications just seem to make a lot more sense to spend less than 10 bucks on some plastic bushings it's no Trail truck just gets used around the house as an old yard dog
This should be similar for a 02 Chevy Blazer?
Josh Matthiesen check tag on the transfer case
mine jumps to N from 2H wonder if thats the same problem ?
I think i put the spring and cap in wrong..i put the cap in first...FUCK
Mine was doing that and all of sudden it's shifting fine.
on a scale 1 to 10 how easy was to. 1 the easiest and 10 the hardest
I'd say about a 5 just cause all the shit you have to take off to get the timing cover off lol
The pads on the shift fork was probably the main issue. Mine would randomly try to jump INTO gear going down the road, feels like someone hitting the floor board with a hammer.
Iv got the same problem.. thanks for your comment... I feel pulling the case will be not in vain./ waste of time.
did the new bushing on the shift fork solve your problem?
yes it did I drove it all of that summer winter and this summer without any issues
appreciate the feed back this was helpful in my case thanks bud. A+++

@@shawngarcia3414 yes they should turn freely with no binding
hey tyler landers i got noises in the front of the motor and burn my oil
would it make a tapping sound if the oil pump was going out
those are probably lifters, which would mean your top half is dry
Thanks for the video man! Saved me some trouble!

What kind of car was this off? If just changing the timing cover gasket, does the oil pump need to be primed?
1997 firebird 3800 series 2 but all of the series 2 and series 3 cars will be the same as far as this housing goes
Tyler Landers Thanks! Nice video btw.
Tyler Landers wow. I didn't know the 3800 Series 2 was in a 97 fire bird!!! I'd love to put my turbo L67 in a 97 firebird!!!
