99-02 TTY rod bolt 21008005. GM parts direct is the cheapest at 1.21 ea in a pack of 8 for 9.68 + shipping.

33ft-lb is the torque spec for the 91-98 rod nut. I would expect that 30->32ft-lb would be more than adequate for a recycled rod bolt. With the inherent inaccuracy of almost all prosumer torque wrenches I would stay away from the TTY spec as if you overshoot failure is highly probable. Not a disaster if the failure is immediate but a delayed failure is a mess.

REWARD EXCELLENCE!

I really appreciate you helping me with the bolts. I buttoned everything up under the hood today & was successful in firing up the fresh motor. She kicked over in about 2 cranks.
Runs pretty dang good, just gotta let the computer re-learn everything.

Default Re: My Saturn SL2 engine build & modification pictures

I am planning to do a couple modifications over the summer, including widening the throttle body and intake manifold, lightened flywheel, headers, and ignition stuff. I might even throw in some flat faced valves to up the compression a "little tincy" bit. Keep in touch yall!

I like it except the white over the Saturn emblem. I like the shiny aluminum with red Saturn badge better. Looks great otherwise, though. How is the engine paint holding out? All of the stuff I have used stated all of this high-temp ceramic crap, and after a few years started flaking off. Other than powder coating, I'd like to try epoxy paint. That stuff holds tight to appliances. Not sure how it'd handle engine heat.

The pre-cat heats faster than the main cat, being closer to the engine. It minimizes emissions when the car is first started. OldNuc likes to think that it heats the O2 sensor faster, but it's not there for that purpose. That's what the heater is for. My O2 sensors heat in a matter of a few seconds, and the front one doesn't have a heater. When I had a heated one installed, though, it went into closed loop almost instantly, and my car doesn't have a pre-cat. Read anywhere else, and you'll find that they're for start-up emissions, not O2 sensor heaters. LOL!

REWARD EXCELLENCE!
