Re: engine miss and then quit...possible opti? (Slick94)
The new opti, water pump, hose kit and seals arrived today. I see I didn't get the seal for the opti so I guess I'll go to the local Chevy dealer. Still waiting for plugs and wires to arrive. Started the tear down. Got to the balancer and called it a night. It sure was tight sliding the water pump out of there. With my mother in the hospital and a couple of hundred paver bricks to install yet to finish the patio I may get this done by the weekend. Lucky I'm retired. BTW, checked the codes and had H16 and H36 both which point to the opti. Thanks for the input guys.

Re: engine miss and then quit...possible opti? (Slick94)
Do yourself a favor and find out what the GM part numbers are for the seals you need. I went to the dealer and told them what I needed, it took 3 days to get them and the waterpump seal was wrong. I explained again and pointed it out on the screen for them and they ordered it again, took another 3 days and guess what? ...... wrong seal again. Looked in my shop manual, found the number, ordered it, waited ...Well, you get the idea.

Thanks. I looked at my invoice and I did order the opti seal also and it was in the box. I have both seals and two o-rings. All I need it the time to get back at it.

Re: engine miss and then quit...possible opti? (Slick94)
I've ordered the all the seals and gaskets for the timing cover.
The whole kit was $12, so I didn't mind getting the timing cover gaskets to boot.
How had is it to pull the hub?
I've got an electric waterpump.
I want to put that on instead, but I heard that if you don't take the waterpump drive out and plug it, the unsupported shaft makes the seal leak. But if I'm doing all this anyways, I could just drop the pan and plug it.

Re: engine miss and then quit...possible opti? (vvv90)
I got the waterpump off today.
The bolt behind the PS pump was a real PITA! :mad
I don't think the waterpump is busted. The weep hole is plugged with oil! :crazy: Actually the whole front of the engine is caked with it. Probably the problem. :rolleyes:
The waterpump drive is right above the opti BTW. Getting a freeze plug over it will be tight.
I got the relays today to convert the pump to electric. You can find them in the trailer light section. No weather pack seal for it though. I'll have to mount it so the leads are pointing down, and wrap it up nice and tight.
I checked the wire I picked, fired her up before I took it apart. The wire is still HOT when the engine is running.
TIP Get a timing chain gasket set ( FelPro ), even if your not removing the cover. Not only do you get all the seals, you get the waterpump gaskets as well! :cheers:

Re: engine miss and then quit...possible opti? (BrianCunningham)
I wish I would've done that. 1.) I would've gotten the right seals without having to wait to order them again, and 2.) the two seals separate were like $20 from GM :eek:

Re: engine miss and then quit...possible opti? (vvv90)
I'll try the local dealer's to see if I can get the installer/remover.
I'll also see if I can just get the stud.
What size bolt is it?
I got the balancer off :cheers:
I used an extention and a hammer, I tried a piece of wood first all I got was a BOING!! as the wood flexed :crazy:
SEARS doesn't sell reverse torx sockets anymore :mad
I tried calling around, no one had them
I jambed a 1/8 socket on it though and got it to work. :cheers:
There's a little water in there, but not much. So I think it's OK
the cap & rotor are definitely gonzo.
I can definitely tell where the seal was riding on the opti drive.
It also looks like that's where all the oil was coming from.
I'll replace all the seals and hope the wear isn't enough for it to start leaking again. :rolleyes:
The plug wires are drenched!

Re: engine miss and then quit...possible opti? (BrianCunningham)
It's likely that the bearings in the opti are shot as well. I'd replace the whole thing unless you'd like to do this again in a couple of months.

Re: engine miss and then quit...possible opti? (BrianCunningham)
Hey Brian, I couldn't IM you :confused: Can you give me the part number for the Felpro gasket set???
Also, a lot of people are having trouble locating the E4/T20 reverse torx screw, let me know how the 1/8" socket worked out for you once you get the cap back on.
Thanks! :cheers:

Re: engine miss and then quit...possible opti? (Strick)
Here's a tip: Take one of the torx bolts out of the TB and use the head as a socket. Just double nut it. Thats how I got my opti apart. Or just flag down a MAC tool truck. :thumbs:
I've heard that tip before, but have never needed to try it.

Felpro TCS 45956
Looks like it's got the seals for both types of optis, splined and large seal.
Great guide BTW
Thank you great help :cheers:

A friend has a press, so I'll take the pump over there to press out the impeller and drive in the plug.
BTW Mine rotor was held down with T8 fittings not T5
There's a lot a differences between the older opti's and and new ones.
Miine opti seal is the size of the crank's :eek:
It's driven by the pin off the camshaft, it fits over the camshaft bolts.
I bought a balancer puller for $15
My Hayes manual shows how to adapt it to pull of the remaining hub.
With the opti fully apart it doesn't look all that bad in there.
Looks like the way these things "fail" is the optical window gets junks infront of it so it can't read the wheel. I wiped mine down. Hardly anything on it. :cheers:

Re: engine miss and then quit...possible opti? (Slick94)
Finally. I got it back together and let it run. The primary fan came on at 182* (160* stat) and it cooled down to 177* so coolant flow must be good. So far no oil or water leaks that I can see. I did replace the opti and water pump seals (used the baster trick) along with the opti, waterpump, plugs and wires. Thanks for all the help guys. :) I take it for a test drive tomorrow. :steering:
