Anyone here replaced the timing chain cover gasket?

Part #14 and #19 in this pic.

I've loosened the bolts but the engine tin surround is in the way of removing the timing chain cover. Anyone know how to remove the engine tin w/o dropping the engine?



thanks,

Your exhaust system is in the way. Once off, you'll see your way to removing the shields to allow access to the covers.

I got the exhaust system off, but am having a hard time figuring out how to remove the engine shields part #11 as shown in the pic.

I wanted to do this a year back or so. One side is easy, the other side is hard. You have to remove the crank shaft pully and the engine mount bar.
Then I just sealed the two chain tensioner bolts. The oil drops are gone now, may be you start doing that first. One bolst after the other, otherwise your tensioner will come down.

I used also luiquid gasket {LOCTITE MADE} and it work just great.

May be in your case it works, so you can save a lot of money and time.

Man, what a job to decide to do with the engine IN.

No way, it's an engine OUT job for ME, I've heard others say it can be done, it's just too much of a headache and difficult to get right.

If it can be done, rest assured, that piece of engine skirt sheet metal needs to be removed...via several 6mm bolts (10mm head) holding it on, check the ones around the AC compressor bracket and there should be some that connect it to the engine support/pulley cover.

Fred is right, you'll have to remove your crank pulley and AC compressor bracket - there's a special tool needed to remove the crank pulley...careful, that is an integrated harmonic balancer/dampener which does NOT do well with licks from a hammer/mallet.

You're entering into a zone where a lot of things can get messed up, so read up on what you can and proceed with caution.

There is a tool to re-install the pulley and assure it is straight, as the crankshaft is beveled on the end and this allows for pulley adjustment...I did not have to use the tool to re-install my pulley, it pretty much sits right back where it was with the help of a little corrosion and wear.

The gasket kit is pricey...TOO pricey.

There is an indentation in the tin for the distributor. If you loosen the distributor retaining bolt and lift the distributor up the tin will come out. That's provided you have loosened all of the fasteners.

Hmmmm, that's a good one Harpreet.

Didn't think of that one...wishing I had my 964 at work so I could check it out.

I figured that one out the hard way!!

A friend replaced the left side, as I recall did a partial engine drop, loosened the a/c bracket, and completed the right side.

hello,

it has been a while for me, but i can tell you that you do not have to drop the engine. if you do loosen up the distributor nut but not completly you can lift it up enough to give the extra clearance without disengaging the gear and messing up your timing. there are 2 10 mm head bolt in the center of the tin that you will need a long 1/4 inch extension and wooble socket to get at . these might be the bolts that you forgot. if you need some help i can give you my number and i will look at my car and help you out. you can do this

...I never said it couldn't be done, I just don't think you'll have all 10 knuckles left when complete!

I can be done, I have helped out a friend, even timed his cams this way...but it's just not preferred in MY book.

My reasoning is simple: if you're chasing down oil leaks, you have A LOT more to consider than your timing chain cover gaskets...I always find it quite beneficial to pull the engine, do some other maintenance, etc.

I'm NOT trying to convince YOU or anybody else to pull your engine!!

..I'm just sharing MY view on the subject of replacing items such as timing cover gaskets and weighing it against the difficulty of removing the engine -VS.- the pain you go through to complete said task with the drivetrain IN.
