Ok, so I've changed my opti more than I care to talk about, and everytime the same thing happens, the o rings rip. Does anyone know the point of the o rings, do they keep oil in? I had the motor rebuilt, when I bought it it had a spun rod bearing. Is there something inside the cam that causes these to tear or what? I've tried everything knowing they're going to tear, I expect a snug fit but damn lol. At times I wish I had the spline style opti. So basically, do the o rings stop oil from leaking, or is that only the actual seal on timing cover?

So basically just another place to leak oil, great. Guess this will always have an oil leak because it tears the o rings everytime and I don't know why. Scouring the internet you'd think I was the only person that has happened to, because there's nothing on this lol. Puking oil is going to be the reason I dump this engine. Especially considering the oil leaking is utterly pointless.

Have you tried lubricating o-rings with engine oil before installing opti? The oil can help o-rings slide into place without tearing.

And, are you absolutely sure o-rings are the correct ones for opti? You might want to find o-rings with a slightly smaller cross section that will still seal the oil in. But will not tear.

Yeah I've tried about everything I can think of. The o rings I've been trying have been the ones that come with the opti and ones from a timing cover kit. Without them it slides in and out pretty easily. I'm not sure if it's supposed to be that tight of a fit or not lol, I know it's supposed to seal but damn. Idk if the cam itself is messed up or I'm just a being a whiner about it, I'm just tired of it leaking. At next replacement I'm going to have to probably pull the cover and double check it.

There’s a chance the TC gasket is leaking slightly also, and running down the opti.
But since were discussing the o-rings specifically, try using a tiny bit of high temp ceramic brake grease (comes in a tube) on your seals and o-rings when installing them.
It helps things slide back together much easier, makes getting the piston back in the brake caliper after you’ve replaced the internal rubber seal a LOT easier.
I hope that helps some.

I've thought about that possibility as well, figured it probably started leaking after the couple water pump and opti replacements. I did the water pump seal but that was it. I'll keep that grease in mind though.

I thru the towel in on my Opti Spark last year and installed the Torghead 24X system, plug and play. I now have a OB11 computer, ID as a 2002 Fire Bird with a "coil over sparkplug" set up and except for the CNC machined cam and crank housing and reluctor wheel all the sensors and coils are GM off the shelf items. I tapped the weep hole in the water pump and using a drilled out a 90 degree zerk grease fitting with a hose I re-routed it to drip harmlessly to the ground if it weeps or leaks. The system works great with a power increase and all new components, I'm good for another 100,000 miles...?

It's a very nice setup, but the unit still goes in the factory opti location and utilizes the o rings lmao. I believe I would still have the same issue with them tearing and leaking oil.
