99 Civic EX...will be replacing the Timing belt soon as it has 100k on it. Looked through many threads, and I understand the procedure, but the only thing I want to verify is the parts list. So far I have:

- Timing Belt
- Water Pump
- Water Pump Gasket
- Tensioner
- Valve Cover Gasket
- AC Belt
- PS Belt
- Alternator Belt

Is there anything else I should be doing at the same time? Oil pump seals or anything?

I want to replace everything with OEM parts which I usually get at http://www.thepartsbin.com

 

thermostat

 

hmmm....ok thanks I wouldn't have thought of that one.

Anyone recommend anything else?

 

cam seal and crank seal

 

oil pump gasket

There is no "oil-pump" gasket. There is a tiny o-ring for the oil-feed return, and a pump-pickup gasket. To replace those, you would have to remove the whole oil-pan. No reason to do that if oil is not leaking from these areas (which wouldn't be visible since they are inside the motor)...

Replacing the crank seal is common, but do you really want to try it if it isn't already leaking?

 

flush your coolant and fill with new coolant.

Uh, you kinda have to do that anyways when you replace the water-pump. But it is important to remember to buy the fluid in the first place...

To the OP: Don't just get the valve-cover gasket by itself. Buy the complete valve-cover gasket set with the spark-plug hole rings gaskets and mounting stud grommets... You will also need some Honda-bond or silicon sealant for the flat-spots on the valve-cover gasket and wherever else it's necessary...

 

thanks for the tips...i'll definitely get coolant and the whole valve cover gasket set. I'll look into the cam seal and crank seals as well....don't know how to do that yet.

 

The old seals can be removed pretty easily with a small flathead screwdriver. You just pry at the outer edges until it comes out. And don't be scared if pieces of rubber start breaking off the old seal. There is a metal ring under the rubber that won't let the whole thing break apart. Just make sure not to get that screwdriver anywhere near the crank or cam. If you nick the spinning surface of the cam or crank, you won't be able to get the new seal to work...

Once the old seal is out, just clean the area with alcohol to get the old smears of rubber off that get left behind. Then lube the inside edge of the new seal & gently spin it onto the crank or cam. Once it's on the cam or crank, you simply press it into the block or head. Now the tricky part is being able to tap it in until it seats all the way. This requires a special tool, but can be done with oversize deep-sockets.

For my CRX cam seal, I actually took the old seal and peeled all the rubber off it until I just had the metal ring thats inside. Then I placed that against the new seal & used a short socket to hammer against and get the new seal all the way into place. I don't think this will work very well when doing the crank seal since the frame rail is in the way, and the crank snout is relatively long. You may want to look into getting the proper tool for that job if your crank seal is in fact leaking. The main problem is that you cant always tell exactly what seals are leaking until you get in there. Fortunately dealerships tend to keep crank/cam seals in stock...

 

inspect cam seals...

if they are not leaking, i would leave them.

Do Civics have a woodruff key behind the crankshaft pulley? I know that Nissan ones can be known to go bad...

The do, but I've never heard of them going bad...

 

Here's what I did for mine:

Timing belt (did tensioner on the second belt change @ 180k)
Water pump (already comes with its own gasket)
Thermostat, hoses and coolant
Acc. belts
Valve cover gasket (only) and HondaBond
Feeler gauges (set valve lash)
*Crank pulley bolt - no, it's not called for. But after hearing how hard it is to come off, replacement didn't seem like a bad thing.
*Crank pulley holder - right tool for the right job

We do have a woodruff key, but our main concern is making sure it doesn't fall out. If you're replacing the front crank seal (I wouldn't if it's fine), you have to take off the timing belt drive gear.....which uses the woodruff key.

Also make sure to have a timing light handy to verify ignition timing before and after the job....and a Helms....it always seems to help.

 

Maybe you can even do the headgasket since you are taking apart the timing belt and what not. That's what I'm doing.

If it aint broke, don't fix it...

 

If it does break, have fun fixing it...

That doesn't make sense...

Are you aware the OEM head-bolts are a one-time use item. Honda says they should be replaced every time they are removed. There goes hundreds of dollars to fix a problem you don't have. It's not like head-gaskets wear out. The only reason to replace a good head-gasket is if you have to dissasemble the bottom end or to have the head reworked...

He means:

If it breaks, you will have to tear the engine down again to fix it, when you could have replaced it with the engine already apart as a preventative maintenance...

Replacing a HG while doing a t-belt job is preventive maintenance??

News to me...

I'm with you. Why would you replace a head gasket if you dont have to? The only time you replace it is if it blows.

Yes, that would sound much better.

It's not broken yet, so don't worry about fixing it, eh? I hate when people say that!

How retarded are you. Replacing a timing belt is required "scheduled" maintenance. There is a big difference between "preventative" maintenance and "scheduled" maintenance. Maybe you were sick that day they went over it in ASE school. Last time I checked, a head gasket didn't show up on the required maintenance schedule...

 

ASE school? I didn't attend a "school." It's pretty much just standardized testing, after you've been in the field for 2 years.
