4.3L 5.3L Chevy Vortec Distributor install

[@IrvinGreene8008]

I have been doing mechanic work for 40+ years and that is the best video on this topic I have ever seen! I think all the "thumb downs" are because this video was not what they were looking for. Thanks for a great and thorough job on the video!!

[@SchrodingersBox]

I generally find the thumbs down counter on my videos is useful in letting me know how many idiots viewed the video. It's like.... useless but fascinating trivia

I have done this install incorrectly so many times I feel like an expert. Even multiple auto shops with so called experts have not done this correctly on my truck I finally figured it out with a combination of elbow grease, baking my noodle, and listening to this fantastic video. The oil shaft slot was what perplexed me. I assumed you couldn't turn that slot thinking it was solid to the timing of the motor. AMATEUR TIP: if you are doing this in a full size 1500 truck: You will not be able to feel the slot with a screwdriver easily or even wedge one in there due to lack of space. Instead, take apart the old distributor and use just the long rod with the rotor wheel on it. USE THAT AS THE SCREWDRIVER. It's must easier to find the slot since it's the rod is machined to be a perfect fit. Also, draw a line on the rotor to show you where the slot is pointed.

[@Spitfireseven]

Not only is this a good video, your heart is in what you do and you can feel it. What is so interesting is the Tonka toy like simplicity of the design. It ain't so simple with other distributors, and I know that from experience. The oil pump slot would get to me. The explanation of orientation is absolutely the most efficient and intuitive aspect of this video. You did a splendid job.

[@elmobutler8142]

Thanks for the video. It solved a problem for this 67 year old mechanic. I placed the pointer where the #1 was marked on the cap and it would not start after I rebuilt the engine. Now I know why. I have built many chevy engines in times past with the old distributor but this is my first new type.

[@Averagepenguy]

I’ve been watching distributor installs on KZbin all week. This is by far the best one for the 4.3. Thanks for good info.

[@marcsanchez500]

This video is very detailed and helpful. my 99 4.3 was missing and backfiring for awhile. I put new plug wires, new cap and rotor. still no help. wasn't until I replaced the whole distributor did my problems go away! I ordered one from EBay for $44. this video made the install a breeze! if your having misfire issues I recommend replacement. take an hour of your time and do this simple repair. thanks so much! BTW, I'm no mechanic but by following this procedure it was simple! watch this a few times and good luck!!

[@marcsanchez500]

I will say, that my new distributor did not have the factory line on it to align it before I installed it. so when I removed the old one, I simply used it as a pattern to make my own mark. simple idea

[@tcbgmgmm]

Hey sir. Appreciate all that you do. Have become a better technician thanks to your teaching videos. Have some learning problems so I have no formal training. You have helped me a long way. That being said. I recently fought a vortec distributor install. As in your scenario. It was out of time when towed in to me. I spent way to much time trying to drop it in. Changed my way of thinking. You know outside the box. Brought it up to number one. Went underneath rotated to next mark on crank pulley in relation to crank sensor. Dropped distributor in at number six. Had wife bump it over until oil pump shaft lined up. Bolted everything up and done. Without your previous teaching methods. My tunnel vision would most likely have continued. Again. Thank you for what you do.

[@Ostobers]

THANKS!! Backyard mechanic that would have struggled with the oil pump shaft without your explicit directions. Bought it and had it in in one hour, 15 minutes which was lining up the shaft. Thanks again!!!

Sir, I was at the brink of desperation until I found your video and gave it "just one last try". Well, I am glad to say that I was able to finally fix this darn issue haha. Thanks a lot! Who would have thought such an old truck had such a distinct way of installing the distributor.

[@freesafe7]

Hard to believe you can find this great information for free. I was so used to the older dist caps I was setting

[@LynxStarAuto]

no need to fight with the oil pump shaft. simply drop it in place, hold the distributor down with your hand, or loosely install the hold down bolt. then turn the engine over by hand, and eventually it will fall right into place. even with the shaft not engaged on the oil pump, the drive gear engages the cam gear enough where they rotate in harmony. you won't lose timing. good vid

[@SchrodingersBox]

+Lynx Star Automotive (Gabe V) Sounds like a good strategy- I'll try that next chance I get

[@RobertPerez-lm8zc]

+Schrodingers Box I'm having trouble aligning oil shaft with drive shaft any suggestion to help me align

[@LynxStarAuto]

Robert Perez Do exactly as I stated in my post above. Drop the distributor in, and when it falls as far down as it will go, turn the engine over at the crank pulley, after a couple of spins, it will fall right in.

[@RobertPerez-lm8zc]

+Lynx Star Automotive (Gabe V) thx gabe I'm going t o have to do that after dropping I realized I'm off due to the fact of having code p0016 correlation of crank and can so I must be off. Also my distributor didnt come with any scribe or paint mark indicating the set back from cylinder 6 on distributor do you know what the set back is supposed to be because right now I'm just guessing and if I knew the set back I could do it the way you described above thank you for your help

I greatly appreciate your thorough, orderly instructions. I successfully replaced the distributor in my '05 Silverado 4.3 Vortec with 97K.

[@snapap690]

I found a way easier method to install. Once you get TDC., take a picture with your phone to see where the top of the gear then just match the distributor up with the picture. Drops right in and lines up on the number 6

Thank you for a great video tutorial that helped me install my distributor which ended up helping me get 2 more years of service from my 2004 Chevy Blazer X engine code, I wish I was smart enough to follow you more regularly I believe my truck would be RUNNING WELL instead of being on blocks. I got it running but didn't correct the check engine situation. I didn't know how, cuz I have been a parts changer. I really appreciate your approach to a scientific step by step / logic process, intuitive approach. I'm learning a lot from you, but there is a lot to learn, and a few tools I'll need.

[@SchrodingersBox]

It's all about your dedication. It take me many times before I learn something!

[@louispasnik5976]

Hey Matt. On the vortex v6, there are 13 teeth on the distributor gear. Thus, 360 degrees / 13 teeth = 27.7 degrees per tooth. If you are at TDC, any misalignment should be blatantly obvious if you are off even a single tooth. On my 2000 Vortec v6, I am somewhere between 5 and 10 degrees off on the distributor mark while at TDC (verified absolute top on #1 with horoscope). This is the closest I can get, any other tooth alignment will be ~28 degrees away. Now, maybe I have something else going on (timing chain)? Also, on some vehicles, it is almost impossible to line up a screwdriver head with the slot the oil pump shaft through a blind hole (abyss) in the rear of the engine, underneath hvac lines and wiring. Once you get first distributor engagement with the cam teeth, but before the oil pump shaft is aligned, you can manually turn the crank until the distributor aligns itself with the oil pump shaft - gravity will cause the distributor to set in place, then you can bolt it down.

[@SchrodingersBox]

Excellent deductions! Yes even off one tooth it is indeed blatantly obvious for the reason you stated. If you continually find it is impossible to line up when doing this correctly, I agree you may need to chaeck your crank and cam timing relationship. Also yes, it takes "feel" to adjust the oil pump shaft- on this model you cannot see it. A strategically placed mirror can be used to help but it's tricky working with a mirror image!

[@louispasnik5976]

My 2000 silverado vortec 6 cylinder has an o-ring on the distrubutor, but it is intended to seal the distributor housing to the engine (hole is in the Intake manifold as i recall). There is no Oring between the distributor and the cap, nor would i want one in my engine.

[@bobsbarnworkshop]

exactly, the drive gear is very coarse so if you're off, you'll easily see it... just pull out the distributor but first mark where the rotor is pointing first... Then just put it back in the way it was pointing. Now this doesn't check the timing, but just gets you back where it was.

[@jacobgonzalez7797]

Bob's Barn Workshop So I mark where the distributor rotor is pointing, pull it out and install the new one in the same orientation?

[@kellismith4329]

@@SchrodingersBox there was no room under my cowl for even a mirror, I ended upusing my iphone held over top so I could see the driveand then adjusted with a screwdriver inside a lenth of conduit

[@SchrodingersBox]

Deric, indeed this is exactly why I like to "start fresh" with installing the distributer at TDC every time. Even if you do mark the distributer's original position accurately AND reinstall it exactly, this assumes the distributer was in correct position to begin with (maybe not as much an issue if it's your own car, but I usually get cars from people who gave up trying on their own and who knows what they've done!!!). I hope this video helped you. I do hate inaccurate repair manuals lol!!!

[@chevymec]

Very good video. What 5.3 motors are you talking about? The Vortec motors that use a distributor are the 4.3, 5.0, 5.7, and 7.4.

[@johnblack9713]

so is this video good for the 5.7 engine?

[@chevymec]

John Black yes it is.

[@dreamweaver961]

I just set my distributor and it was backfiring through the exhaust. I completely forgot that fact about the vortec distributor cap. Thank you now I can get it running again.

[@latemodelGM]

the title is misinformation 5.3s dont have distributors only old vortecs 4.3 ,5.0 , 5.7

[@beninchesapeake]

Matt, This video helped tremendously with my Chevy 4.3 but I did mine just a bit different. Since I had a hard A/C line directly above the distributor, I didn't want to be removing and replacing the distributor in order to line up the oil pump drive. My solution. I noticed that each time I lifted the distributor and replaced it the oil pump drive would move just a few degrees. So with the engine at known TDC on the compression stroke I realized that if I lifted and replaced the distributor enough times eventually it would settle in with the rotor pointed at the 6 mark. Took maybe 7 or 8 times but it finally worked out perfectly with the rotor pointing directly at the 6. As a check I rolled the engine over twice and each time I reached TDC the rotor was perfectly aligned with the 6! Engine fired right up with no codes or miss fires. Again I want to thank you for giving me the basic idea for getting the timing correct!

[@SchrodingersBox]

It's a great strategy and in fact a validated one. Indeed there is an established technique which I call "walking" and it basically is as you said- eventually the distributer will have to end up in its correct position eventually but it may take as many times as there are teeth! You can speed up the walking by setting the distributer exactly 180 degrees off after each walk. In other words, when you lift the distributer and it turns slightly as you described, turn it 180 degrees from where it is and insert it. Then lift again and set it 180 degrees again. This gets you in the final position in half the time.

[@beninchesapeake]

Interesting. That thought did occur to me after I was done. Honestly while I was doing it I wasn't even sure it would work, so I just took the slow and steady approach. I want to thank you again for the basic idea and knowledge. You got me "pointed" in the right direction!

Great write up. It helped me organize my thoughts to reassemble the motor. I used a compression gauge to cylinder number one along with chalk marks on harmonic balancer. Aligning the oil pump shaft proved a little tricky for me. I couldn't get the screw driver head into the slot. So I took a piece of 1/2 inch electrical conduit about 8.5" long and dropped it over the shaft. The screw driver could pick it up real easy then.

So on install I was fighting with it to get it in. I got it in but it was just slightly off. The truck still ran, but has a misfire. So I started looking up new videos and came upon yours.

Hey Matt, first off thanks for the video. I found it to be very helpful and had more information then my repair manual. so people know why their engines not starting. If your tdc on the balancer, but your not lining up on the six, your just before it or just after it that is the exhaust stroke, so just turn the crank another 360 degrees and line it up until it's lined up with the "6". 95-97 has no white line so line this up right before the screw hole before the six and your rotor will line up.

I then remembered a comment on here about a different approach (Gabriel V's) which I re-read, and using his method (install the distributor in the correct position and then rotate the engine manually until it seats on the oil pump) I had the new distributor correctly seated and fastened down in about 15 minutes. Cranked right up, no codes, runs great.

Yes the infamous corrected cap that is notorious for cross firing from one cyl to another and causing havoc with these particular engines anytime I have any issues w bad running if at all or any misfire issues it's the first thing I try I have on hand what I know to be a good one just for this I remove the old one replace w the one I know to be good if the problem goes away bingo I go. And buy a new cap and rotor for the engine and in at least 75 % of the cases it's a wrap and off we go for another idk how many thousand miles but yes this is the most informative video I've seen on this subject by far and the very best explanation of how to do it follow his recommendation to the letter exactly and you will have success if not to the letter and its even the slightest bit off one tooth it will not run now you have to start all over again as well, finding tdc on the compression stroke not the exhaust stroke of no 1 cyl just remember the distributor only turns at half. The speed of the crankshaft it takes two complete revolutions of the crank to get one revolution of the distributor that is where most people get very confused and end up having all kinds of problems wrenches being thrown cussing and often. Times maybe some bleeding from skinned knuckles it happens dont laugh it is a true story lol no one compression stroke if it's the exhaust stroke and you line all this up it will not run and may even do some crazy popping and huffing and jumping around its. Not good for it. At all so do it right guys do it once take your time dont get in a hurry or flustered the oil pump can be a pain but again take your time and make sure its lined up correctly and whatever you do make sure the bolt is in to hold down the distributor before you try to start it again dont laugh I've seen this happen the distributor will want to be pushed up once it does start if you even Get that far and bad things happen very quickly to gears and oil pump shafts if this step is missed just be thorough and take your time guys it's not that hard to do really honest I've done hundreds on old school small blocks and this Is the very same exact thing except the cap is different and no 1 is in a different place gone is the having to refer to the firing order of 18436572 that Is a thing of the past on the vortec the cap takes care of that for you with that crazy looking cap that gives us so many problems lol sorry rambling smoke another one eh lmao have fun and stay dirty and no I'm not Eric the car guy

Seems most comments are about confusion on TDC, marks aligned and #1 comp. vs. exhaust.When you pull out your dist. (if it hasn't stripped inside somewhere) just take off your cap. align the 6 to the rotor and put the new one in the same. If your wanting second confirm the marks should line up the fist balancer mark underneath to the mark on the timing cover (that's seen easily from underneath) and the second mark lining up to the mark from above (also on the timing cover, harder to see).....there are two marks and two lines on the balancer.Also..lots of reman. dist. have the dimples installed wrong, you're just going to have to play them as dealt or return for another.

This guy matt knows his shit.I had changed my stock Distributor with an alum. base.Distributor.This distributor is a lot harder to install compared to the Hei distributor.It took me awhile on how to changed it.But got it done.

[@HBFTimmahh]

Yes it did. Thanks Much. Need to double check but I am pretty sure I got it set right. But to be sure, I'll pull my distributor, reset TDC, realign the distributor marks, and drop it back in. Had to redo the intake gasket on my 1500 with a 4.3 Vortec. Exactly the info I needed. Thanks for taking the time and the vid.

[@emokilleremokillers5259]

great video very informative but you did not show how to set #1 to t.d.c. but once i got that issue resolved this video was a great help thank you. im only pulling the distributor because i had low oil pressure and knew that the oil pump could not be the problem. I found that the old distributor was wearing from rubbing the intake and leaning to one side causing low oil pressure.

[@fightnight47364]

The rotor can be installed in only one position to the distributor , due to the locating tabs underneath the rotor next to the mounting screws holes. The locating tabs are offset from the mounting screws holes.great vid 👍

[@SchrodingersBox]

Yes that is true for any rotor on any distributor. . The point is the position of the rotor RELATIVE TO FIRING POSITION varies upon engagement with the cam.

[@SchrodingersBox]

Thanks for the comment and hopefully the new cap fixed it, Chris. If not, On a P0300 it is very possible a fuel delivery problem could be the issue as well as many other things. Unfortunately without seeing on a scantool which cylinders are misfiring it can be very difficult to diagnose. For example, if it turns out all the cylinders on just one bank are mifiring you can rule out many more possibilities than if the misifires are random through the whole engine. Good luck!

[@SchrodingersBox]

@Dungorm-Couple things come to mind- with bad bearings in the distributor coming first as you suspect- removal of dist and inspection should reveal that. worn teeth either on dist gear or cam gear could also explain. Also, the body of the dist is a snug fit in the intake hole- on either side of the intake hole are small oil holes-dist body not fitting snug will lower pressure here, although this hole also feeds the upper cylinder heads- if you have some valve chatter too I'd suspect this.

Schrodingers Box hello I have a 97 blazer 4.3 and after finding tdc and setting distributer the rotor prong was facing to the number 1 spark plug. It cranks and runs fine.

[@SubliminallyObvious1]

The best description I have seen without question!

[@GM_TECH_FAB_40831.]

very informative video. I was going to take my truck to a shop for this replacement. Not necessary after watching this.

[@goejeni]

Hey Eric if your still having problems, I found out why so many people go insane working on this project. If your at tdc, mark one on the crank as explained here, but your not lining up on the six, the rotors just before it or just after it, that is the exhaust stroke, so just turn the crank another 360 degrees, pick the distributor up and move it back half way between two full drop down spots until your (screwdriver not needed then). once to the other side, viola you just need starting fluid.

[@christophersmith3247]

Thanks for the great video! Very clear and to the point. The dimple on distributor gear and mark on distributor shaft was awesome.

Great video Matt, I got a do a distributor on a 1998 silverado 5.7 I will do exactly as you shown in the video, thank you matt, cheers from Ontario ca.

[@jonclark9757]

Matt, THANK YOU SO MUCH for the video!!!!!! It helped my ignorant ass tremendously. Is it possible to add a few comments......? I hope so, and please do not take this wrong. 1) As for people like myself, might wanna include to put the vehicle in neutral (DAMN, THAT MOTOR WAS EASIER TO TURN OVER!!!!), 2) I used the alternator to turn the engine instead of the flywheel, 3) To fit the screwdriver into the slot for the oil pump, I used instead the lever bar on a small mechanical/hydraulic floor jack. The slots are identical, and there is THE PIN used to relieve the pressure to lower the bar....? Can be your guide to "line up" the slot correctly. Got my 2000 Chevy S10 on TDC. Thanks again Matt.........

[@kellismith4329]

I will add to that to just go ahead and pull out all the sparkplugs to begin with, I too had left my manual in low gear (habit) and wondered wtf trying to spin it over lol; but I also learned that turning the crank bolt with a ratched not so easy while fighting the other 5 cycles of compression - because of this I realized also that the spark plugs I replaced maybe 30000 miles ago are shot already, the centrepins melted down the gap is approx 67 thou ! The factory set I changed around 100000 miles didn’t look near as bad. The factory used double platinum and the centre pins were large, when I changed them it was recommended to me to “upgrade” them to irridium plugs with a finer centre wire - needless to say I will be going back to the double platinum this time around.

[@sietedosbagged1916]

My friend You are the best . Excellent I mean Excellent video, an instructions of how to properly install a distributor.

[@SchrodingersBox]

Glad you liked it!

[@davewill0819]

Thanks so much for sharing your knowledge! I had to replace the distributor on my GMC Safari and I don't think I would have attempted it if I hadn't seen your video and I don't think I would have succeeded without the info you provided.

[@kloster2p]

This was very instructional, thanks for the content!

[@MikiAbtan]

Your videos are great to watch, I learn so much and I feel I understand things conceptually thanks to your videos. Great job, Thank you!

[@jesusmata5852]

Thanks bro you helped me pull through. Can't thank you enough, you are awesome. Everything worked out like a charm. Just like you showed on the video. Thanks for showing me the light. Can't thank you enough bro.

[@dialyork9]

Matt, even after so long, this is still an outstanding video. You saved me hours of time. Thank you.

[@SchrodingersBox]

Thanks man, yeah it seems to still be the only correct video out there for this application. Amazing isnt it!
