I'm ordering a timing set today. What other parts will I need to do this job?

I'm planning to order:
Melling timing set
timing cover gasket set
valve cover gasket set

Do I need intake gaskets? other items?

I'm ordering the stuff from Rock Auto today with hopes to do the job this next weekend.

Any help is greatly appreciated.

Thanks in advance!

i dropped my cradle and replaced $7k worth of parts at 167k miles. saved it from the junkyard and is on its second life. search “enclave engine removal/drop. what to replace”. mines 2009. all p/ns listed and accurate and the car actually runs great for the time being.

my car came factory installed w cloyes. i didn’t replace the sprockets (i would have if i thought about it ahead of time, but didn’t feel they needed to be replaced after feeling almost to freeplay). i listed all parts replaced and opinions if needed it or not. mostly, it was” 167k and easy to get to” while i had engine out

ultimately, i was at 167k, no engine lights for chains/engine performance. the tensioner had room to expand and my teflon guides were worn .010-.015”. replaced due to exxon valdez seal oil leaks everywhere. i replaced oil 4-6k intervals. i feel oil change interval is key to long guide life. imo, it’s more guide wear, not chain “stretch”

consider the 4 cam gears/phasers at $50/ea. mine started sewing machine rattle around 130k. common problem. easy to do while ur there.....

inspect ur cam lobes and lifter rollers. 3-4 of my cam lobes had small patches of shine worn off tip of lobe. starved oil oil. i figure it was combination of bad oil pick up tube seal design of material selection from gm (was gum rubber and lost its seal compression) and that the engine leaked sooooo much oil over the last 40k mike’s until i finally fixed it - had a hard time keeping up w oil level constantly.

i ordered 40% of the parts from rock auto, the rest from an online dealership. probably 40% off msrp pricing

watch the cloyes video on chain instal. was very, very simple. you will need to rotate the phasers slightly as the guides have worn putting them in a different location.... like 1/4 to 1/3 tooth. i had one chain guide to the primary drive w frozen bolts. i left the metal frame and exchanged teflon guides

lots of great times on you tube videos. sounds like uv been doing ur research

I ordered a timing chain set, valve cover gaskets and timing cover gaskets. I will look things over as I dig in. I do not have access to a lift so dropping the cradle is not really an option for me. I picked the vehicle up for $1,500 as a running and driving vehicle, albeit with CEL, DIC codes and a stinky interior with water leaks that I have sorted out now. I still need to pull the carpet and dry that and the floorboards and disinfect though (hopefully getting rid of the smell)...

My plan is to change the timing set and gaskets and see what that does for it. Another member posted that doing that actually helped many of the DIC codes as they were related / thrown as a result of the timing issues. I'm hoping I have similar results, but who knows.

I'll swap out the chains, hopefully get it running as intended and then re-evaluate at that point. I've done some research, yes. Really thankful for the detailed videos online about it. They definitely take some of the mystery out of it. Gives a guy some confidence going in.

great deal! once u pull the valve covers, you’ll see how the PO took care of the engine. definately inspect the cam lobe tips

when i had my oil pan off, i eyeballed the piston cylinders, looked smooth and shiney

i noticed p/n’s changed over the past 2 years as i was researching parts for our redo

how many miles on urs?

measure the chain guide thickness.... curious how much urs wore. i posted mine (and still have the old ones) so we can compare notes if u have the time

i raised the front of the car in the garage, used 4 hydraulic jacks to lower cradle on 2 harbor freight furniture dollys. if i was short on clearance, i was going to remove upper intake and ps pump reservoir to give extra room to slide it out drivers side wheel well. it was much easier than i thought. my garage is normal ceiling height.

Had a question, is it the plastic part on the guides that wear down causing the chain to jump or does the metal chain actually stretch?

I have the old parts from my timing chain and now I'm curious. I'll edit this post with the numbers after I measure.

I saw a pic of someone's new and old chains and there was noticeable stretch in the chains from old to new. The guides all seemed fine. I haven't torn into mine yet, but I will take a look at that when I get them out.
