Cam And Crank Seals Really Necessary?

[MadManMike]

Hey guys,

I got my pathy totally taken apart, and I was talking to the mechanic across the street ( used to work for toyota and nissan dealerships) and he says he would never take a car that far apart with out doing the cam and crank seals... I was planning on not doing them, but if I am going to do them I am at that point right now.

 

What do you guys think? if they aren't leaking should I do them any way? Also, how big of a pain in the butt is it? will I just make them leak?

I did the timing belt twice on my old one, and never touched any of the seals. I never had a leak from any of them either.

Hmm...

Hey another question I had was the quality of the timing belt... I bought one at napa and it's a goodyear.. but i am now thinking maybe I should have gotten one at the dealership... any advice on that?

nah, you shoul dbe fine with a good year unless they had a bad year.

 

same as simon on the seals here.

Ive done 4 timing belts, no cam or crank seals....

 

I did thoughly inspect every single one to verify they were not showing signs of leakage or failure....

The only reason I changed the rear main on my 91 was that it was showing signs that it had leaked, it was a small one, but it had been leaking.... Now it really leaks.....

of course, in a few month or so when you notice your seals leaking, you'll wish you would have done them whileyou had it apart.

 

 

oh... and I haven't done mine either... on either engine.

How much torque should I use on my water pump bolts? or any bolt going into the aluminum block for that matter..?

According to my mechanic neighbor about 30ftp of torque.

 

Update on progress:

Well I decided not to do the seals ... But I figure I will do them on the next timing belt change, that will be about 10 years from now

 

I decided to replace:

Thermostat and t-gasket ( don't forget to buy the gasket along with it like I did)

Water Pump

T-belt tensioner ( wondering if I should have done a new spring with that ?)

T-belt

All new rad hoses (including the bypass hose)

new AT tranny cooler lines

all new drive belts

...

and I think thats it..

 

so far I have all the new parts on... just need to re-assemble every thing...

 

Hmmm... guess my next pathy repair adventure is replacing the exhaust manifold studs

Considering the seals are about $15 for all 3, I'd do them just to be sure. My LH cam seal was seeping oil when I did my t-belt. This is the only time you're going to be able to do them...
