We will continue the timing chain service on a GM 350 by upgrading to a double roller timing chain. After the double roller timing chain installation we will bar the engine over twice so you can hear the compression difference in this hi-performance 350. Every engine we have done a chain too you can hear the compression difference. If the engine has over 200,000 miles doing a timing chain service may make other parts of the engine weak (Head Gaskets, Seals, Gaskets)

Dude, that chain is way to tight. Something is wrong
Hey guys pls tell what I'm doing wrong I changed the þiminf chain and sprockets and I still have alot of sloppy in the chain after all said and done an I doing some thing wrong ?????????? Pls help lol yours truly poncho
When you're heating a torus (donut) like the crank gear, you want to heat it outside-in. Although this gear is too small to really matter, as a general rule you should always heat from the outside-in. If you heat from the inside, it's expanding and fighting against the outside. I am usually heating gears that are 4ft+ in diameter.
Good video. Funny and informative m
About How far back does the crank sprocket sits onto the crank? Thanks in advance.
What timing set did you use ?
What timing set did you use ?
is about a 1/16 inch deflection ok in the chain if pushed in hard?
Heating the gear up with a torch will harden and forge it…really dude? C'mon. There is a method and process to hardening steel more than just getting it hot. It is very possible to weaken the temperment of steel by heating it, albeit you likely did NOT weaken it with the amount of heat you appeared to apply to it but you did NOT make the gear harder with your torch I promise you that
Thanks very much! I love your channel!
I have a 87 k20, it hasn’t started we’ve tried everything electrical and it still won’t start now realize the chain is stretched, can the chain being over stretched prevent the truck from starting at all?
Very informative.ty
How did u get the oil pan out to clean the block surface and the pan itself. I have a 93 Sierra and its looking like the whole motor needs to be pulled or drop the 4 wheel differential just to get the pan out for a good cleaning and seal for timing cover as well .
I have my timeing cove off and there is a little slack on both visible side of time chain should I change it. Out ? ??
I like to thank you guys I brought a motor off of let go everything checked out good compression I took the valve covers off everything look clean inside the motor so I put it in my truck and I couldn't get it to run right swap carburetors distributors mess with the timing and nothing was working the things backfiring had no power so tomorrow I'm going to take a look at the timing chain thanks again guys keep the videos coming
On late model 5.7 engines you have to grind a small portion of the block behind the cam gear to installed a double row chain. If you don’t the cam gear will rub against the front of the block
I keep an old electric hot plate for installing various press fit gears in manual transmissions and such.
This video saved my ass. In the middle of swapping out the chain was wondering what kind of lube your soaking the chain and gears with or if I could put em on dry
Good video but dont you have to line up the dots on the gears?
