How to Remove Oil Pickup Tube GM 4.2L - Part 1

[@voidisyinyangvoidisyinyang885]

Wow you end the vid with that VERY Seal that you had to replace later. haha. Awesome work - talk about taking the car apart!! fascinating. thanks

[@marcosaman]

Never mind I guess it was just in the 1st 2 minutes of your video but they have been very helpful to me

[@Ron-h4l]

Kevin how did you remove computer bracket to remove the intake

[@Hawk_eye]

Great videos, thanks!

[@KevinNadeau]

👍

[@codihash4007]

Is this the same process for the 2wd

[@KevinNadeau]

Mostly yes

[@codihash4007]

Did you take the top of the engine apart ticket to the iPad as well or is that due to you doing the timing chain?

[@codihash4007]

To get to the oil pan*

[@KevinNadeau]

@@codihash4007 I was replacing the valve cover gasket too, that’s why I took the top off.

Hi is this 4x4 envoy?

[@KevinNadeau]

Yes it is👍

[@danielcarmona9243]

Hey @kevin where did you purchase your service manual? Thanks

[@KevinNadeau]

Daniel Carmona My dad bought them for me as a birthday present back when I first got the truck. You should be able to find them with a little internet searching.

[@richardrodgers8530]

Trying to fix the low and erratic oil pressure on a 2003 Envoy 6 cyl. With 223000 mi With the aid of an optical inspection tool and watching Kevin's video changed the oil pressure sensor and that did not do it. SO!!!!!!- Jacked up front on jack stands, removed skid plate, drained oil and removed filter. In an effort to find the center of the oil pickup tube drilled and tapped a 5/16x24 (fine thread) inline with drain plug and towards the rear about 2 inches. That made it possible to insert the lighted optical inspection tool to find the location of the pickup tube screen. As it turned out it is centered in the oil pan (left and right) and one inch to the rear of the drain plug. Drilled and tapped another 5/16x24 hole. THE PAN IS ONLY ABOUT 1/4 INCH THICK. DO NOT LET THE DRILL GO ANY DEEPER OR YOU WILL PUNCHER THE PICKUP SCREEN. With Berrymans carb cleaner with plastic straw sprayed off the gunk buildup.(inspecting with optical tool) until clean. Used vacuum to clean out both holes, sprayed area with contact cleaner as not to leave any oil on surface, bought two 5/16x24 hex bolts, hard flat washers, rubber washers and Permatex gasket maker to plug the holes. Put new oil and filter in and WALLA!!!! No more pressure problem. Hope this might help

[@richardrodgers8530]

CORRECTION--- Finally went with 3/8x24 fine threads in holes to see better

[@KevinNadeau]

Awesome Richard! You saved yourself a lot of work by doing that. Thanks for sharing.

[@erikc7201]

What did you use to drill the holes into the oilpan?

[@pwrcat23]

Erik Cardoso - Used an Electric drill

[@pwrcat23]

UPDATE - The oil pressure is still doing great. Aug. 2019

[@Badge1122]

I also had the oil pressure gauge drop at times. Once I started a 60 mile trip and about 10 miles in it the oil pressure dropped to zero, I bumped it in N, cut the engine and restarted it and the oil pressure came back. I started searching on here to learn what is going on. Some changed the sender and it fixed it, some changed it and it did not fix it. After seeing the oil pickup screen it looked small to me and figured even though my engine looked clean on top the screen must be partly clogged. This is what I did, it may not work for you and I am not saying anything bad about anyone removing it and cleaning it the correct way. My 07 TB is 2 wheel drive and I still did not want to drop the pan as its driven nearly every day. I changed the oil, regular 20w40 and added about a pint of Marvel M O and figured that with 7 quarts would be about like 5w30. I started driving it and had the oil pressure to dip a couple of times and then no more dropping of the gauge. I drove it about 3K miles , changed to proper F S oil. Still no problems with it dropping. Still plan to add about a cup of MMO and drive it a week or so before each oil change. Do as you wish but this worked for me. Hope this helps someone like me that searched every where to find a safe solution and keep my TB on the road. It has 143K on it now and running great.

[@Badge1122]

I see that I posted the above 10 months ago. Now the TB has 150 K miles and still no oil pressure problems. Been changing Full Syn oil at about 3500 miles and now not adding Marvel MO any more. I am glad it worked for me.

[@drscopeify]

@@Badge1122 Thanks for the update. I have the same issue, I changed the pressure sensor but that did not fix the issue. I added SeaFoam to the oil and the dip in pressure went away but once in a while the car will stall at idle and the pressure does appear to drop so I might try MMO before my next oil change. I also plan to try full synthetic.

[@ReallyRandomThoughts]

Thanks for all the videos, I'm fighting this issue too. Changed oil pressure switch, but issue comes back at idle after about 15min. May try some seafoam in the oil and see if there is any sludge. Oil was changed recently.

[@KevinNadeau]

RandomThoughts I tried an engine flush with kerosene too, but that didn't seem to fix the issue.

[@ReallyRandomThoughts]

Kevin Nadeau subscribed for future vids, but did cleaning the pickup fix the issue? I'm down a tow vehicle until I get this sorted. Mine is an '04 TB I6 with about 247k miles.

[@KevinNadeau]

I should have everything put back together this weekend. I'm hoping this solves my issue. I wound up having to replace the timing cover (with oil pump) because I broke a piece off trying to take out the check valve on the oil pump. So I now have a new oil pump (don't think the old one was bad though) and a clean pick up tube. I also cleaned the gunk out of the intake ports while I was in there. That should help a little with fuel economy.

[@voidisyinyangvoidisyinyang885]

@@ReallyRandomThoughts How's your 04 TB I6 holding up? I'm kind of scared to use MMO since i don't want the oil pickup screen to get clogged. This is an insane amount of work just to clean that out!!

[@voidisyinyangvoidisyinyang885]

I just added a half quart of MMO to help clean out the engine... will soon get the oil changed again....

[@thadandrews4868]

did u have to lift the motor to get oil pan off

[@KevinNadeau]

No, I did not have to lift the engine.

[@jdaemon33]

What did you use to pull the harmonic balancer off with? Great videos as well, thanks! I'm just about to start my own timing chain adventure, and these videos will help a great deal.

[@KevinNadeau]

Thanks for the kind words and good luck with your timing chain cover. This is the puller I used for the harmonic balancer, the ones you rent from auto parts stores won't fit. amzn.to/2JYy9gR

[@jdaemon33]

@@KevinNadeau Very nice, thank you Kevin! I've been looking around for that.

[@AirmanJH]

@@KevinNadeau I know this is an old thread, but I bought a cheap gear puller at Harbor Freight and used a grinder to shave off a bit of the rounded part of the hooks. Just what the doctor ordered!

[@KevinNadeau]

@@AirmanJH Perfect👍

[@kenoger2866]

Hi great videos ...........Did you ever have any engine knocks or ticks when this was all starting? i have an 03 trailblazer that i am trying to figure out what is knocking? thanks great work!!

[@KevinNadeau]

Ken Oger, I did have what sounded like a bad bearing. I believe it was related to low oil pressure. The sound went away after I fixed my low oil pressure issue.

[@kenoger2866]

yes i have that now but nothing with the gauge going low ......thinking of changing the vvt first maybe cam and crank sensors..........want to start small things first oil pan looks like a nasty job to do

[@ericcorse]

Just starting this series I'm curious how often you change your oil? I have always changed mine at about 5k miles. (02 TB mine since new). I haven't had any issues (KOW) ~ 230000k miles.

[@KevinNadeau]

Eric Corse I change my oil at about the same interval.

[@voidisyinyangvoidisyinyang885]

I do 3000K usually - that's what I was told for TB for more mileage.

[@bishop5166]

Those axles come out without taking the wheel bearing off. Just pop the top ball joint, disconnect the brake line holder bracket and pull the top of the control arm out towards you far as you can. you have to tap the axle out at the oil pan FIRST...then pull the upper control arm out. Honestly you really dont even have to remove the axle nut...pull it out near the oil pan and set it to the side.

[@KevinNadeau]

Good tips, thanks!

[@pwrcat23]

Don’t know the brand of electronic inspection mirror. Used it to find the exact location of the screen on the bottom of the oil pick up tube.

[@KevinNadeau]

How did your pickup tube look?

[@pwrcat23]

Pickup tube screen was covered with debris (no metal) that had to be restricting the flow of oil. After spraying as in prior instructions cleaned up great. When finished the oil pressure was back to specs.

[@KevinNadeau]

@@pwrcat23 Awesome. Wish i had thought of that!

[@crazy4ltx]

WTF you need to take whole engine apart top and bottom to get to the oil pan free??? Would have been nice to do a step by step of the lower removal instead of the music!!

[@KevinNadeau]

Unfortunately you do need to do a significant tear down to get the oil pan off. Check out my other videos in this series for more info.

[@trailtooth1447]

Did the pickup tube fix it or did you need a new oil pump?

[@KevinNadeau]

Yup, the pick up tube fixed it. I had to buy a new oil pump (aka timing chain cover) because I broke it.

[@JesseHGA]

@@KevinNadeau lmao you have to get all the bolts out first

[@derrickmendoza4173]

Doing this job now. I had a blown headgasket. Doing the timing chain while I'm in the. I'm on week 3 working on it

[@KevinNadeau]

Good luck! It's not a terribly difficult job, just time consuming. Now removing the head bolts can be tricky since they are torque to yield bolts. And be sure to use new head bolts when you put it back together.

[@derrickmendoza4173]

New head bolts are a must. Head is back on with new bolts. The tensioner had a broken piece so I had to remove the oil pan and that sucked. Your videos are a great guide

[@marcosaman]

I liked your previous videos but this one there's just to much music I can't concentrate on everything you are saying

[@jamesyarbrough4777]

thats alot of varnish.

[@KevinNadeau]

Yes it was 😁

[@DeeBee2013]

It's so hard to hear you speak over the background music - please stop doing this - when you speak to people in real life you don't say - hey wait, let me go get my ghetto blaster and play it in the background for extra atmosphere. You just speak.

[@SM-uo6nx]

Didn't bother to watch. Someone put a loud, obnoxious musical track on the video.

[@KevinNadeau]

If I find out who did that, I'll have a talk with them 👍

[@chuey9313]

I can hear over the music just fine, and the music stops less than a minute and a half in, before he gets into the video. Patience grasshopper.
