Re: 22RE Intake Manifold Removal

Hey! Soak it with WD-40 or something similar. Soak it over night. Even better, start soaking it while the motor is still warm - but keep drenching it as much as you can hourly. Bill

You need a real penetrating oil - and WD-40 is NOT one. Repeat after me, "The WD in WD-40 stands for Water Displacement"

It's the best stuff to have on hand for quickly drying out the ignition system after you drive through rain puddles. But the main ingredients are Kerosene and Stoddard Solvent, meaning it is NOT a long-term lubricant, and is at best only a marginal penetrating oil.

Kroil or PB Blaster are two much more effective petroleum based penetrants. And if you ever need to work on HVAC or food processing equipment, MARS "Rust Buster" is NSF approved for incidental food contact - and it doesn't stink nearly as bad when you get it hot.

Get the penetrant down to the base threads you're trying to get open, and soak it several times a day over the course of a few days.

If the bolt isn't moving more than a partial turn without applying extreme pressure, STOP FORCING IT! - soak it again, come back tomorrow, try again. Otherwise you start snapping bolts off, which suddenly makes a simple job into a whole lot more complex procedure.

If you can stand the smell of hot solvents and it is still drivable, driving the car is OK in between treatments. It can actually help, as the gap between stud and block (or bolt and nut) will expand and contract with engine heat. When you arrive you let the engine cool down for 10 minutes and blast it again. It will soak in.
