I have a 3400 for an 03 Impala, and doing a rebuild on it with high performance parts. It had a cracked head gasket and is costing me over $2200 to fix.
Have check the 3100s for a broken camshaft too.If you see this,the cam bearings wash out and the block is junk.Getting a high quality reman is the better choice,the vehicle is in and out in one day.A rebuild,vehicle sits for a couple weeks.
We're doing an engine rebuild right now on my 95 Cutty, Whole Upper Part including Rocker Arms, push rods and all was covered in clumped up oil, took it down to the heads, one is covered in carbon and partly rusted, one of the rollers is completely flay, so we know already we have to replace one of the cams, lucky we're sending the heads and block to the shop to get fully done, then we can start putting it all back together and fire it up!
That’s the best reason to do it: you don’t know how but you’d like to. Go for it. I think it should be a mandatory freshman college course everywhere. It’s easier than it might look, plus it’s one of the most rewarding things you can do, and you wind up with a mighty chariot you can trust because you know every part of it is assembled right. There’s no guesswork really, everything fits where it fits. You can rent specialized tools from the dealerships, and you’ll only need a few specific tools for the job so you don’t have to buy tool sets. This guy did a very thorough job ($$$) but in most cases you won’t need to resurface everything. I rebuilt a 4 cylinder engine a while ago and decided not to re-bore the cylinders, just hone them, which spared the expense of new oversized pistons. I just replaced the piston rings and it worked perfectly. I’m about to overhaul a 3.1 v6 and I’m only going to replace all of the gaskets and rod bearings, & maybe resurface the crank if need be but probably not. I just need it to run smooth and not leak for at least the next couple of years. Total cost: under $150 for the gaskets and bearings. Most external components only need cleaning and a little tlc.
About to do my mom's 3.1l buick century head gasket kit for the first time.It overheats even after replacing thermostat,water pump and a leaking heater core(still gets no heat). The only thing that worries me is breaking/stripping bolts. Any tips on avoiding or removing stripped bolts?
@DaleJr2010 Thanks. The engine comes out pretty easy actually, All the bell housing bolts are accessible from the top and the rest is just the accessory drive, motor mounts etc.. it runs great i just got in a hurry and never got a video of it. ill add it in soon.
awesome, i have a 2000 Buick Century Custom with the J type 3.1 SFI V-6 just got the improved lower intake manifold gasket kit installed.... they are nice.
Check the reman crankshafts before install,can be bad.I have seen this,machine shop checked the journals and were out of spec.If you see a 3100 with a cam broke in half,block is junk right away.Washes out the cam bearings and this a problem with the 3100.Best option is to buy a Jasper reman with the upgrades already done having a 3 year 100,000 mile warranty
@jimmy101112000 hey thanks for the post... Very late reply but yeah i ended up having to buy a new gasket kit just to get the metal/rubber ones that i wanted before i put it together. those plastic gaskets are garbage.
@jamesanthonyspencer Nope, i just had a local machine shop clean the block and install cam bearings. I figured if there wasn't any damage then i didn't need it. they did hone the cylinders for me for a few bucks and press in the wrist pin for the new connecting rod. the piston that spun the rod bearing was contacting the head slightly and left a clean piston mark in the carbon on the head.. i was worried about machining, so i checked it for any indentation ..and it was all level thankfully
@90W7 Ok I just saw them at 11:45 those are the same ones I did on my brother's car. You should not have any issues with those. You can make some money by replacing those on other people's cars for $400 to $700per job using those gaskets for anyone who owns the 3100 and 3400 engines.
I don't like the plastic lower intake gaskets. I would have bought the felpro $85 ones which are rubber and metal. I bet these will fail at the same time as the factory ones or sooner. But the rest looks good.
Doing the same now man , great job but I got a question. Did you have anything machined? Like the block or heads? Its expensive and I'm wondering how nessacary it is.
Its been a while now but i think your referring to to the pain in the ass one that you cant get a wrench on it hardly.. if its that one... i think i had to use the open end of the wrench and broke it loose then using a stubby wrench i had to do a million 1/8 turns till it came out. pretty sure its that one, the rest came out normal.
It's in the fuel tank. On older cars, you need to drop the tank. In newer models, take out the backseats and peel back the carpeting in the trunk to find an access panel.
That is an impressive rebuilt, you should do a engine rebuilt manual on this to see if anybody else wants to rebuilt their Chevy 60-degree V6 engines.
wow you did all that work for a 3.1 hat's off to you man.
Try not to "project" your tastes onto another man

I admire people who can do this. I wish I could do this to mine but I dont have the tools or to much knowledge on overhauling an engine. Great video.

Thanks for this video, much appreciated!
Good deal. Ive only done a handful of them but its not that bad of a swap considering the problems that occur when they do go bad without being fixed.
👍 Thanks im doin a 3.1 orig camaro right now!
awesome, i have a 2000 Buick Century Custom with the J type 3.1 SFI V-6 just got the improved lower intake manifold gasket kit installed.... they are nice.
That intake manifold is a problem with most of these engines but once you replace the gaskets, These things run for long periods of time

I thought this was a turbo Grand Prix. That block looks pretty shout though.

Oh God, this is what my mothers 2001 Buick century is doing, knew about a slight coolant leak, now it has a slight knock.
@90W7 ok great thanks man. nice work
nice lil project brother!!!!!!!!do you have a video showing it running afterwards?
I never did make a video of it running for some reason. My brother drove the car for another 6 years and finally got rid of it for something newer.
yea its a ok job, ive done a few similar jobs that weren't as extensive, like a leaky set of fuel injectors on a 3.4.
Nice Work. is it difficult to remove engine from top? could we see it run after? Thanks

But the rest looks good.
Doing the same now man , great job but I got a question.
Did you have anything machined? Like the block or heads? Its expensive and I'm wondering how nessacary it is.
You're doing wrong the torque sequence, You must begin from the Center to the outside screws
Can you help me with the information manual of that motor? I'm rebuilding one this and I need the specifications. Please!
u get a vid of it running yet?

I need to find the fuel pump on a fuel pump works

I had the same problem today cut the fucking thing
