im in the middle of replacing a rod in my truck with 112K on it, would it be wise to go ahead and replace my timing chain and gears? is it easy to do?

 

Yes, it would be very wise to do so. It ain't that difficult to put on.

 

you should have changed it 30K ago.

 

yeah, i was on another site that said they usually go out around 100k......im gonna try and do all that i can while im into it........anything i might not be thinking of?

 

when you go into the front of the motor, you might as well do water pump, water pump bypass hose, temp sensor, t-stat, timing set, and front crank seal (in timing cover).

are you doing the rod with the engine still in ? oil pump, oil pan gasket and rear seal (2 piece at rear main).

just curious, what led to rod problem ? i'm just wondering if you might have any other hidden problems that you won't know about until you put it all back together. your leaving heads on, right ? i might do rod and lower end stuff and then see how it runs before investing more time and money. just being cautious about the amount of money thrown into it.

 

yeah, im doing it with the engine still in......i had a cold air intake and sucked in some water....im gonna take the heads off and get a valve job and try to port and polish them my self.....


in my haynes manual, it says to pull the distributor and support the back of the camshaft to do the timing gears.....do i have to do this?

 

You do not have to remove the dist. And just for the heck of it, I have a FSM and a Haynes, I looked in the Haynes and it says nothing about removing the dist. So I don't know what you are looking at , maybe camshaft replacement?

 

im sorry mine is a chilton, but i did look again and i guess i was looking at camshaft....sorry bout that

 

Just my opinion, but I think your going to go through a lot of work only to find out you'll still need a new engine. I would just replace the engine now with a good used one. As far as the timing chain, I have 170k on mine now, but when I swap motors with my V10 truck, I will do the chain. I'll take pics too show how much or little slop is in it after 170k

 

Actually that's a good point. I would do as little as possible and see if it runs first. On the other hand, if you already have the parts bought and installed you can always swap them to the new motor.
