05 honda civic timing belt replacement, cam seal

If the cam seal is not leaking I would leave it alone. I say this for a couple of reasons, the first is that if you don’t use an OE part it may leak, the second is that if you don’t install it correctly (there is a special tool for this BTW but you can just use an appropriate sized socket) it will also leak. Think of it as one of those things that falls under “if it ain’t broke, don’t fix it”. You don’t need to remove the cam just the cam sprocket if you do end up replacing it.

Impacts should be fine removing cam and crank bolts. Make sure you loosen them before you release tension on the belt.

I agree with this man. I just wanted to throw out that impacts should be fine for bolt removal.

Quoted From TJAbrigo:

thanks eric!! will it be ok to use a impact to get that bolt off from the sprocket. how about changing the crankshaft seal?

Actually that is my preferred method and I normally break the bolt loose before removing the old belt this way I don’t have to worry about it coming out of time.

The same applies to crank seals, if it’s not leaking and you’re going to replace it with a non-OE part I would skip replacement.

If you are that far in, then don’t cheap out on a tensioner. Replace it.

As for tensioners I don’t see too many Honda tensoners go bad but I test them all by spinning them, if they spin freely or have some noise I replace them but if they have some resistance I reuse them.

In all the videos I’ve made on the subject that is exactly what I recommend.
