Camshaft Seal and Front Crank Seal

[blb]

For those that have changed the camshaft seal and front crankshaft seal......what's involved?

First, the camshaft seal....Im thinking you have to remove the valve cover, top timing belt cover and timing belt sprocket off of the camshaft, then use a small L shaped tool to push into the flexible area of the seal and try to pull it out. Am I on the right track? Do the bearing caps on the camshaft have to be removed to replace the seal?

Next, the front crankshaft seal. I'm thinking you have to remove the timing belt covers, the crankshaft pulley (harmonic balancer) and the timing belt sprocket off of the crankshaft. Then use an L shaped tool to push into the seal lip area and try to pull the seal out. Am I in the right track on this?

What am I missing?

What are the most probable areas for oil leakage coming from around the crankshaft pulley area on a 4AFE? I realize that it could be leaking down from the valve cover gasket, cam seal or front crankshaft seal, but what is the most common source of leaks on a 4AFE?

Your on the right track, but use your fingers to push the news seals in, The one on the oil pump needs to be flush with the pump and the cam seal just needs to be straight you really cant push it in too far. As for leaks the places your think of are right, Theres also a oil galley plug in the front of the block But I dbout thats leaking.

So, is the oil pump seal normally a PITA to remove, or is it normally not too bad to get it out?

Also, when you say the oil pump seal needs to be flush with the pump, does that mean you drive it in till it bottoms out?

I did both cam seals on my 4AGE. It was kind of a bitch to get them back in. They were supposedly the right seals but didn't seem like it because they didnt fit unless I grinded off some of the rubber a little lol. Use something exact size to lightly knock it in once you pushed it in as far as you can with your thumbs. It never leaks so I guess it worked. :p

Biggest thing, just make sure you get the timing right when you put it back together. 4AFE is pretty easy, just line up the marks. :p

I can attest that my 4AFE leaked at the camshaft seal. It was old and dry and it spun around with the cam every so often!

The cam shaft seal comes off easier if you pull the cap. No big deal, but reseal the cap with silicone very lightly and keep it out of the oil grooves that run to the back of the seal.
You only need to put sealant on the edges of the cap, outside of those oil grooves.

There are a couple of different oil seal removers that look like ice picks with the ends bent. These work great for pulling the crank front / oil pump seal. Just be careful not to gouge the metal while you pull the seal out.

There is a half moon plug in the head at the front end of the intake cam. You might want to check that also. I've seen those leak.
