i NEED A PART NUMBER FOR THE OPTI-SPARK SEAL TO THE TIMING COVER THANK YOU

 

The little o-rings around the drive?

I know those come in the felpro timing cover set, along with the water pump gaskets too.

 

Its not the Little copper looking o rings are they, because i thought those were for somthing else

 

I think mine were just black rubber.

But we are talking about the two that go on the opti shaft??

 

hmmmmmmm. does it make a difference that this is for a 94 non vented setup

 

Hmmm Maybe so, I have never seen a non vented.

Hopefully someone else will chime in.

 

Still Need A Part Number What One Is Right This Is The One From Jason Chromer- 12552428
Local Chevy Dealer - 10128317

 

Why would there be a fdifference? Cromer is a GM dealer parts guy..
I checked and the GM p/n's you list are:
12552428 95-7 opti timing cover seal
10128317 93-4 opti timing cover seal

 

FWIW if you mean that 2 or 3" rubber O-ring that goes over the backside of the opti into the timing cover my opti that I removed for the first time never even came with one. Although the non-vented opti I bought in replacement did. Weird I thought

 

Unvented opti has no 'o'ring' behind the housing?

 

I have a 1994. is the size in the seal a difference. I put the seal from chromer in it and it leaked..... so im going home to try the one for my year. weird huh

 

Are you talking about the o-rings on the shaft, or are you talking about the seal which presses into the timing chain cover?

You can get a timing cover gasket kit from Advance Auto or Autozone for ~$15. This is a felpro kit which has 2 o-rings, all 3 seals which press into the timing cover (water pump drive, opti drive, balancer hub), the timing cover to block gasket, and waterpump gaskets.

where do the o rings go right on both sides of the shaft. which would make it a double gasket idea because it goes into the seal on the timing cover

 

I don't understand your question (if you asked one?)

Here is a diagram of the timing cover and Here is a diagram of the opti spark (both compliments of Shoebox).

Notice the two different timing chain covers on the bottom of the 1st picture. The '93-'94 definitely has a smaller opti drive seal.

So again, which seal are you asking about (o-rings or seal in the timing cover)? Like I stated earlier, all these seals can be purchased in a kit from your local autoparts store for $15.

ok well i got the gasket and i need to know where the 2 little o rings go.do the go on both ends of the opti spline drive or what
