PLEASE keep the Chevy content coming ! A+
Yea, I thought I was seeing things with the battery car content. Yuck!
As soon as I noticed the Dewalt drill I thought, when was this video posted!? 😆
86 was the 1st year of the one piece rear main seal ,the rope seal was used until 59
I didn’t have anything to pop the seal in so I used an old gm distributor cap it worked quite well
Great job on the videos
Did the crankshaft turn at any point in time?
I noticed that the alignment of the part was180 degrees (almost) opposite from the start of the video.
@raju katwaroo Yes. We turned the engine over just to make sure the seal was seated properly. That’s not a necessary step.
Was curious about that myself
Why did they go from the two piece seal to the one piece? Its a major rectal itch replacing it this way.
believe you can remove the two rear studs and not have to drop the pan if its not leaking
Love this your the best!
The oil pan gasket looks new but i dont see a video for that?
Great content!!
This is the same style seal for a L31 vortec 5.7 in a 98 suburban
Not sure, I’d check the felpro website.
Awsome video n info!
why did you rotate the motor before installing the fly wheel i am just curios that's all
This was a great video. Gona help me install my rear main on my project car. Thanks!
The Amazon link for that seal shows it comes with some other gaskets that were not addressed in the video, where are they for
@Justin Pennington There is a carrier that holds the rear main seal on the back of the engine. Ours was not leaking so we did not replace it.
What’s the part number on that new seal?

could you show where is the ground strap that goes to the engine and chassis
@Luis Eduardo Reyes Sorry for the late response.. Center bolt in this video. th-cam.com/video/v23UAXcLKWI/w-d-xo.html
@@SuburbanRanch Thank you very much for your answer, I have a 1995 Chevrolet Silverado 4x4 truck and three years repairing various things, this has helped me a lot. Greetings!
@@laloluisreyes77 Glad the videos are helpful!
FYI....manufactures who make PTFE rear seals are very adamant that you DONT lubricate the crank surface or seal surface. I know that sounds strange, but I have seen this stated many times in writing.
This was not a ptfe seal. I would not recommend using a ptfe seal
@@SuburbanRanch Good to know. If you got the scoop on pitfalls of PTFE seals, please share, I will add them to the don't buy list no problem. Thanks in advance.
You need perfect conditions to get them to seal. I have enough problems getting regular seals installed and leak free!
Rear mains common to leak? Seems like mine is leaking oil. Initially thought it was trans fluid but trans is fine, oil is low. So, I’d imagine that’s the culprit.
@Andy S Fairly common I believe.
@@SuburbanRanch cool. Looks like I’ll be doing that this summer.
No loc-tight ? All mine were loose thought it was the clutch.
@John Wilson We torqued them to spec, but no loctite
Any suggestions on removing over torqued flywheel bolts? I got three of them, but cant even budge the others with a breaker bar and the heads are starting to round.
@Siggy Retburns Penetrating oil and an impact gun?
That just happened to me, welding a nut over them didn't work, I end up removing the heads of the bolts, and then removed the flywheel, after that the bolts came out easily with a vise grips.
@@ricardohernandez9108 i just used an er309 stainless rod at 100amps , welded it ,let it cool, came out flawlessly.
Off the topic, will Gen 1 882 heads work on a 1992 G20 350?
I’m not sure. Sorry!
will take to shop for repair. How many hours labor is that billed for?? anybody know??
@bigbuttlounge You have to remove the transmission. I would assume around 8 hours of labor
I just had my transmission rebuild but notice it leaks a lot of oil. My transmission has a warranty and a shop that did oil change said its coming from main seal. Is it some transmission place can fix?
@Clendon Robinson You have to pull the transmission to get to the rear main seal. I would think a tranny shop could do it.
@@SuburbanRanch thank you for answering. The transmission guy who worked on my truck said it's not the main seal because he changes the seal on his work. So I don't know where now :(
Thanks again.
@@clendonrobinson6867stop driving it and get a pressure washer or soap and water and plenty of towels. You’re gonna have to clean your undercarriage surface area up. Find the most northern point of your leak after cleaning and run it to temp. and there you go bub. Hope this helps!
Does a 96 tahoe have the same rear main seal as the one in this video?
@In God We trust I believe so
I have a 1992 4.3 liter v6 C1500 5 speed manual and my rear mainseal is leaking, would this video help me for my truck or is their another video you'd recommend?
@J J This video will be helpful but definitely some significant differences between the models
@@SuburbanRanch I'm having problems finding a cover plate for my rear differential because my refill plug is seized up and the only way 2 refill I think correctly is with a new cover plate that'll have a refill plug and that's hell not even lmc has them but also autozone & O'Reilly cannot figure it out. The rear pinion seal the same Cannot figure out the specific yolk & pinion size for the truck I've done gone through 2 new yolk & pinion neither pinion seal would go flush with the rear differential and the flange on the seal is like curved and I'm thinking the 1 I need is flat? I don't know I'm just completely confused I even bought 2 separate books for the truck with still no help.
@J J Have you looked at Summit? Would something like this solve the problem? www.summitracing.com/parts/msr-7107
@@SuburbanRanch yea but it's harder on there 2 find exact parts ,lmc is alot more down to detail and they don't have it also summit wants an arm an a leg for everything hahaha
@@SuburbanRanch it's a darn good truck just a few minor issue's
What size bolts does it hold at one-piece housing in
@bobby saltkill Sorry, I’m not sure.
Belive 10mm and 11mm
When did you replace the oil pan. Noticed it was leaking when you removed the front diff.
@Kevin Yeip We did that off camera along with the front timing cover, timing chain, and intake manifold gaskets. Probably should have done a video on it but it was early on in the project.
Hi where did you get that oil adapter
@Cesar Granados Sorry I’m not 100% sure what you mean by oil adapter. Do you mean the pipe we used to get the seal in? If so, we got that at Lowe’s
Is the 454 the same way
@Carnut Sorry, I’m not sure on that. Maybe someone else can answer though.
👍👍👍👍👍😎
Did this help a p0174 code?
Or a p0171
@Alejandro Juarez No it does not
