i took my opti of my 1994 z28 and it seem to have oil on it and maybee in it.i dont have the little socket to take it apart yet,but can that happen to these things and does that mean the whole thing is shot?what is the cheapest way to go to fix these or replace them and stiil have some dependablity.thanks for any info

 

If it has never been changed, it's time. A genuine GM opti is probably the best value at this time.

 

where is the best place to get a gm opti?have you ever heard of a cardone opti?from advanced auto with a lifetime warranty and are they any good

 

If you have oil in your opti, I would tend to believe you have a leaking WP or Opti seal in your timing cover. This is not uncommon and while you have your opti off I would check them and probably go ahead and replace them. Very easy and do a seach as tons of info will turn up.

 

what is a wp seal and where is it and where is theopti seal

 

The WP (Waterpump) seal and Opti seals are two circlular seals in the timing cover. One is located directly behind the WP and the other is directly behind the Opti and they seal the timing cover to both. See the diagram below and look at the two circular holes in the upper portion of the timing cover. Top one is WP and middle one is for opti.

thanks for the diagram.can i change those without taking the timing cover off?thanks

 

GM/AC-Delco/Delphi, they are the same thing. I don't recommend any others. thepartsladi on Ebay seems to be a fair price. Beware of others on Ebay. There is a GM parts contact listed on my Tech Page.

That drawing looks better in its non-condensed, original form...http://shbox.com/1/engine_front_diagram.jpg

 

do i have to take the timingcover off to change the seals

 

No, you don't.

 

you can pick up a new ac-delco opti from summit racing for like $310 bucks. they ship very fast

 

You can also check with these AC/Delco dealers:

www.oehq.com
www.autopartsgiant.com

They have very low prices on all AC/Delco parts.
