Ive watched a dozen videos at least and youre the only one to mention this, i was so confused because when i tore my engine down it looked like it was 180 out according to the dots, you made it make sense, Thank you!
I watched 100 videos and I’m proud to say you the only one who got the dam thing right..I’ve been trying to crank my small block for 4 days 180 degrees off…thank you!!
I wished I would have watched your vid before putting my engine together. I've been cranking for days with no compression. Finally got it to work. Great vid
oh my god thank you so much. im doing the motor in my 84 gmc (first motor build) and you just answered all my questions in one shot. This video should be at the library
When dots are together (cam at 6 and crank 12 o clock) you are at TDC on the exhaust stroke. When both dots are at 12 you are on at TDC for intake/power stroke
Same Here; After so many videos of timing chain setup/adjustment especially from certified expert mechanic; this video explains to you about the dots facing away n facing each other and why distributor is 180 degrees off, thank you for this video and explaining it well, cause i was going insane trying to figure out what I was doing wrong...
Thank u so much nobody on UA-cam ever explained it like u did I was wandering why my cam was pointing up now I k ow abs I’m 100% confirmed with what I have to do thank u so much!!!!! Grate job
😂 lol I also thank you a million, I couldn't start my engine ,got back firing ect.. after I followed your instructions it started right up, thanks again 🤠👍💯
I did the same with a back fire so loud it had my ears ringing for a few hours. After that I was scared to crank it over again. Watched this vid I’m back up and running
So what your saying is after lining timing gears up rotato engine over once and cam dowel should be in 9 o clock position and leave it there for final assembly?
Thank you for taking the time to fully explain that. I did fuck it up my first time putting it back together. I moved crank with distributor in and didn't really pay attention. I watched your video again last night and knew exactly where I fucked it up. Thank God it didn't damage any engine parts. Wish me luck for the restart.
@@SquarebodyStuff you know how many people's sanity you saved bro. You should get a "Metal Of Chevy" if that's a thing lol. I'll be watching your stuff first sir.
So on the intake stroke both will be at 12 so I gotta turn it one more time where the crank is at 12 and the cam sprocket is at 6 to get it on the compression stroke and then I can start putting it back together?
A very very very important and overlooked step by 99% of amateur engine builders is to check the clearance of the top timing gear and chain from the 3 oil galley bosses behind the timing gear, some engines will clear with no issues but alot of blocks especially the later style roller blocks the timing chain will rub against the block and fill the engine with very fine metal shavings, I have taken apart a ton of backyard built sbcs where that gear or chain was hitting and left a bad grinding spot in the block, the only solution if yours is hitting is to take a grinder and clearance the block or use an oem timing set, if you have a block completely disassembled it's always best to add a bit of clearance there before the block gets it's final cleaning. Some of the double roller timing sets will give you instructions to check for clearance, please in the future don't overlook this step and inform others to check also it's a very very common issue that alot of people run into.
@@johngrepo9976 I have never seen a thrust washer used on one of these but in theory the on the backside of the gear is a machined wear surface but the real problem is the blocks oil passages bosses can be casted too thick and hit the gear teeth if you do some Google search on this topic you will find pictures of where they hit, not all blocks hit/rub but most do there are alot of people who have gotten away with slapping them on and just running it but always check.
Yes. I spin every engine I build (not a shop, but a seasoned mechanic), then check for any interference. The machinist I go to always ensures the galley bosses are ground down with new plugs installed in the block at that point. Definitely good to always double check clearances.
Thanks, I'm glad my videos have helped out. If you work the chain around in a tub of oil for just a few minutes is sufficient. All your trying to so is get some oil inside the links.
I comment pass few days , about my distributor being off 180 degrees, so I did what you said in the video but no change; engine crank but no start; took it to a mechanic and conclusion was that all piston had no compression 80 to 90 , was too low , thats why my engine wont start not enough spark on piston.. so he had to overnight let it dry ( piston n spark plug) and would turn on; but will only last for 20 or so minutes until if flooded; so will try to use a can of deep creep foam or seafoam spray from oriellys and added to the pistons leave overnight and check compression; seen other videos that will add compression 10 to 15 more . will see ,
So if I want to removed a gear drive I assume there will be dots on those to line up at 6 and 12 and I just pull that off and replace with double roller with dots in same position and all good? Correct? And will a double roller fit behind a SWP on a SBC?
So basically when the intake valve closes that's when I want to set crank at 12 and set the cam gear with timing chain on to 6. When I rotate to cam gear to 12 that is when I should feel air blow out the spark plug hole?
Just the opposite. When the intake valve just closes your crank will be at 12 and the cam gear mark will also be at 12. That is top dead center (TDC) of the intake stroke. Rotate the crank one more time and both valves will be closed on the TDC of the compression stroke. Crank mark should be at 12 and the cam mark should be at 6.
Question for ya? I just installed double roller chain and its tight. the thing that's weird is if i rock crank very slighty back and forth i feel a tiny bit of play. it seems like there play between lower gear and chain. Is that normal? seems like less than a 1/8 movement. thanks
for some reason i cant get it to drop the rest of the 8th of an inch when i have it set exactly like that piston at its peak camdot 6 o clock 180 turn to 12 with crank rotated and its does not drop all the way down in it
between 13:57 and 14:00 before you cut the video the top and bottom gear was at 12 o clock,then after the cut the cam gear was at 6 o clock and the crank gear was at 12 o clock...my qustion is after you went 180 degrees AFTER you installed the timing chain did you keep roating clock wise till the dots meet at 6 oclock and 12 oclock? (doing my first rebuild)
If you have both of them at 12, and install the distributor, you can put it wherever you want at that point. I usually just leave it there. No since in rotating it anymore than you have to before startup and break in.
It the point of instilling the chian it will be when the dots line up close together. Cam dot will be at 6 and crank will be at 12. Now that info is good for small and big block chevy. Any thing else you have to check a manual to double check. If the heads are on and rockers installed, it's when the exhaust valve is closing and the intake just starts to open up. ua-cam.com/video/nehh879I1CM/v-deo.html
Thanks for the tip. I'm pitting an Edelbrock top end kit on my 78 Nova. Will be the first time doing it. How do we know when we are on top dead center intake stroke?
@@SquarebodyStuff Thanks bud, also since my engine will be in my car, I'm assuming my transmission would have to be in neutral in order for me to turn my engine.

I am resealing up my engine and while I have the timing cover off I figured I'd throw another timing set in there. This video helps me know exactly what I am going to be looking at. I also am going to be doing a rear main seal. I have found some good videos out there but not many. That would be a good video for you to do. Showing replacing a rear main seal with engine inside the truck. You teach and explain things well. I understand the job now from watching another guy's video but it seemed excessively long. I think you would do a good one, without the unneeded stuff .
I have a question that I know you can answer, I installed a comp cam 3200 timing chain kit, the chain has slack on both side of the sprocket which Is too much, but I don’t have the lifters lashed or preloaded yet. My question is When I valve lash the lifters and preload them will the chain get tighter or do you think I need to go with a shorter timing chain? Thanks in advance.
I've tried to explain this on a few of my tiktok videos and I've become some kind of SBC villain. I shared the link to this video on my page, I hope thats alright and I hope it gets you some views. THANK YOU
Just to make sure…. You install the gears and chain dot to dot… ounce installed. You make a 180o revolution to put the dot at the 12 position before putting your distributor… right?
Turn the crankshaft 360 degrees. That will have both dots at the 12 o'clock position. That is TDC on the firing stroke on #1. This is where you stab the distributor.
I know. I stopped using that intro over a year ago. I started to hate it too. No need for a theatrical intro for a UA-cam channel. Now it's just a 5 second intro. I do appreciate the feedback.
@@SquarebodyStuff False. It covers only whatever engine you're working on. Can you put the same timing chain from a 4.3 on a 5.7? No? Gee I wonder why that is: maybe because IT'S A DIFFERENT ENGINE
Actually, the 4.3 and 5.7 do take the same timing chain. All small block chevy engines from 262 through 400 use the same timing set. The installation process is the same for the big block chevys and several other American v6 and v8 engines.
@@SquarebodyStuff sigh...what's the point. They're not even the same length timing chains🤦🏽♂️🤦🏽♂️🤦🏽♂️ can't make this stuff up. I'd love to see you try to put a timing chain from a 4.3 on a 5.7. Make sure you record the look on your face when you realize "wait a minute... It doesn't fit"
If you don't understand that when you install timing gears, when the dots are lined up you're firing #6 cylinder. You should not be working on engines. Furthermore, you don't have to worry about what way your distributor is pointing. Start wires as it's on #6. I never had a motor crank for more than 1 minute before it started.
