2001 SL2
2002 SL2
Default Timing chain cover

Hello,

Recently I tried to remove the old serpentine belt pulley from my 2002 SL2. You can guess what happened. There is a "collar" that is pressed into the timing chain cover, and it fractured (a previous mechanic probably put the bolt on too tightly). Repairing this is clearly out of the question.

(I have other reliable transportation, so I am not in a hurry here. I literally don't care if this takes 6 months of spare time to get it right. And I have the skills -- I rebuilt my Honda CM400T "from the piston rings outward" years ago.)

The car has about 153,000 miles on it and has had several owners. So "the rust and the dust" is all I have to judge how the car was maintained.

I can still get the timing cover new, thank heavens. I have a few questions however:

(1) I will be doing this with the engine in the vehicle. Should I drain the coolant and remove the water pump?

(2) Do I really need to remove the power steering unit and alternator? And will the water pump gasket work a second time, or should I supplement it with RTV?

(3) What type of RTV should I be using here? Any specific brand? Temperature rating?

(4) I was thinking about replacing the timing chain while I am replacing this cover. GM dealers might still have the Delco tensioner, but not all parts are available from dealer stocks anymore. Would a kit from Cloyes be a good choice?

(5) Will I be able to see the extent of timing chain wear when I take the cover off? (There is no clattering that predicts imminent failure, thank goodness.)

(6) What IS the right GM part number for that cover? Part number 21000910, or something else?

I have the skills to replace both the cover and the chain. Please let me know any tips you might have, thanks!

I know everyone is going to say I am nuts - but I would pull the engine.

I don't contort well. My hands are too big. I also don't want to do the job and get so-so results.

It's just one of those jobs that is far easier to do with the engine on a bench - where it's easy access...

A recent post:

Here is a picture of the timing cover off with the water pump and alternator on.



Note in this picture the o-rings are missing. That is why the cover came off! Was heartbreaking.

Save time, pull the motor. Especially if it's an automatic transmission.

Dazed Re: Timing chain cover

It is tempting to use "JB Weld" and stick the "broken peg" on. Then when I attach the pulley, and the bolt gets at least finger-tight, the JB Weld will prevent the broken piece from rotating, until I can tighten it down snug. But with vibrations and heating and cooling cycles, I don't want to trust that repair. I had my plastic stick-shift bushing fail inside the center console on one of my Saturns in a parking lot last July (I replaced the bushings on both cars with the steel part). I don't want any more sudden catastrophic failures.

(Photo is attached, it seemed the easiest way to do it.)

(I found a timing chain cover 21008772 on fleabay, which is the part number stamped on my broken cover. It will arrive next week.)

Waiex191 --

What about the o-rings? Were they in those two cavities on either side of the crankshaft in that lower photo? (my cover is not yet off so I don't know) If they were gone, because of deterioration, then oil lubrication will be affected, right? If mine are deteriorated, will I be able to get new o-rings separately? Will I have to buy an entire engine gasket set?

Dazed Re: Timing chain cover

EDIT: Thank $DEITY the manual transmission shifter bushing didn't fail on the freeway, or I would have been stuck in fifth gear, and then if I had to stop in the fast lane in afternoon traffic, I would have been in a really difficult situation.

And the 15-minute limit on editing a post is stupid. I just thought I would mention that.

I am sure your old o-rings are fine. I had new ones in my gasket set. The machine shop took out my old ones when they ran my parts through the cleaner. Because I hadn't taken them out personally, I missed putting them back in. No o-rings means no seal to or from the oil pump and no oil pressure.

Edit: yes the two round cavities left and right of the crank is where they go.

CM400T- the Orings are available separate.

Bryan C. I'm impressed with the foto quality, esp depth of field looking down the timing chain.

That is a designated camera, correct? (ie, Not a phone shot)

Default Re: Timing chain cover

As a part of my cylinder head repairs last year (2x), I can attest that the front cover R&R with the engine in the car is a PITA.
If I still had the car AND had to do this again, I would PULL THE ENGINE. I removed the "front" motor mount bracket, which was itself a nightmare. Then there's trying to shoehorn the cover back on, with the bead of sealer applied... Then trying to align the oil pump onto the crankshaft. All of it in cramped quarters

Of course, If I had pulled the engine, I would have drilled the pistons, etc., and figured out why the stupid thing was pumping oil into the coolant... despite a complete cylinder head job. Oh well it's sold now.
