My apologies if this has been asked before. Is it possible to change timing chain without pulling engine? Everytime i look for infomation on changing chain. They are doing it on an engine sitting on a stand. I've checked youtube as well and its always a rebuild being done on a stand never in the car. Any reason? 71 RR 383.
 
Thanks. No gasket issues to be concerned about
 
Easy to do pull radiator need puller for balancer, replace timing cover gasket and seal. Water pump needs remval and good time to check bearings.,
Thanks. figuring engine has over 103k miles on it and i probably should do it.
 
I would recommend a good quality gearset.
I'd also plan on a new water pump and thermostat along with hoses and even belts.
Then everything out front is good to go

As far as I know everything is still original. I had purchased the car after the original owner passed away. It sat in their garage from 1981 till I purchased a couple of years ago. Any recommendations for gearset? Thanks for replies

Sure can, easy stuff. Make sure the gasket bolt holes line up on the bottom side of the timing chain cover before applying sealant. Here's a few pix from the last time I did it.

Well I guess I know what I'm doing this spring once it warms up and the snow and ice are off the driveway. Thanks again for addressing my concerns.
 
You should also loosen a couple more pan bolts that go in the block. This will allow the cover to come off the dowels easier.
 
Your's will likely be a "single" bolt on the cam.
Any double roller chain type should be good
Could be a Melling, cloyes or the summit brand.

So I need to loosen the front oil pan bolts. I think I see the dowels in the one picture.
 
Is this something that I'm crazy to do sitting in a driveway?

You should have it all apart in a hour or two with simple hand tools. You will need a puller for the harmonic balancer.

Excellent, should balancer be replaced as well?
 
You shouldn't use a puller that grabs outer diameter. Balancer will come apart.
 
When you get the balancer off, check the rubber between the inner and outer halfs to make sure it isn't all cracked and breaking apart. Buy a new water pump before you pull it apart it will need one for sure. I don't even pull the rad but it only adds 10 minutes.
