Yeah Bill, that is the conclusion I've come to for my 94 as well. I'm going to change the opti... and see if that fixes the problem. Good luck with yours, let us know how it works out.

 

Have you decided what kind of opti you are going to install? Are you planning to change any of the other ignition components while you're in there?

 

Well, I've got the original unit which had 63K on it and ran perfectly. I may try that one or get a new GM unit... have not decided yet. I don't think I'll replace any of the other stuff yet.

 

From it sitting for six years there was moisture in your cap and it corroded the tabs on the cap itself. try cleaning the opti out and that should solve your problem

 

Given my mileage of just over 100K, should I consider putting on a new timing set while changing out the opti? I can get a stock set at a decent price. How much more work is that? Is it difficult to set the timing?

Thanks in advance.

 

Are you in Dalton with this car?

 

No. I live in Lansing now. The car is in Kentucky. This car was my daily driver when I was living in Dalton. I still come to Dalton every now & then. One of my best friends teaches school down there.

 

I'm in KY working on my car this week and one task is to fix an oil leak/s in the intake manifold.

Is there any benefit to using RTV on the gaskets themselves? Good idea, bad idea?

 

Seems like that guy replaced everything but the car.

 

The shifter **** is still in great shape. I'll probably keep it.

 

I have found out when I have a miss with my car, I replace everything at once. Opti, Plug, Wires, O2's etc. Works like a charm. And yes, optis can go crappy just under a load, mine did it last year.

Get a stock MAF, don't worry about granetelli or whatever it's called. Don't remove the screen either.

As far as intake leaks, I don't see why throwing some gasket maker of somekind would hurt. Good luck plugging up the back of the intake though...

 

I did go with a stock MAF and I won't be removing the screen.

I'm also replacing the optispark, coil, ignition control module and water pump right now. I may also get into replacing the timing set. I'm not sure yet. I'm planning to hold off on plugs and wires until I do headers. If it's still missing after all this, I may change them out beforehand. I'm pretty sure that the plugs and wires were replaced not very long before I put the car into storage.

My optispark is covered with oil. It didn't really look like the front of the intake was leaking. So, I'm guessing either the seals in the timing cover are leaking, the timing cover itself is leaking, or both. Dropping the oil pan to remove the timing cover sounds like a big pita, which is why I'm debating whether to even look and see what kind of condition my timing set is in. But it might be stupid to get this far into the engine and not check it out.

If nobody recommends otherwise, I'm going to go ahead and put a thin film of rtv on each side of the gaskets. I probably won't get around to doing that until tomorrow.

 

How long should I allow the RTV to cure before trying to start my car? It's been about 36 hours now.

 

24 hrs. You will be fine at 36 hrs. Go let her rip. Good Luck.

 

02 sensors wouldnt cause that problem. They are only taking readings once hte car is fully warmed up.
