Safety precautions (read and follow)
- Work on a cool engine. Hot oil and surfaces cause burns.
- Park on level ground, set parking brake, chock rear wheels.
- Use a proper floor jack and support the vehicle on rated jack stands on the factory pinch/weld points. Never rely on the jack alone.
- Wear safety glasses and gloves. Keep hands clear when lowering the car.
- Dispose of used oil and gasket material per local regulations.
Overview of the job
- Drain oil, remove components blocking pan, remove oil pan, clean mating surfaces, install new gasket (± RTV per spec), torque pan bolts to spec, replace drain plug washer, refill oil and filter, check for leaks.
Step‑by‑step procedure
1. Preparation
- Warm the engine to normal operating temperature, then shut it off. Warm oil drains faster and carries debris out.
- Park, chock wheels, set parking brake.
2. Raise and support vehicle
- Loosen front wheel lug nuts if wheels need to come off for access (not usually required).
- Lift vehicle with floor jack under the recommended lift point and place jack stands under pinch welds or frame rails. Confirm solid support before crawling under.
3. Drain engine oil
- Place drain pan under oil drain plug.
- Remove oil filler cap to help speed draining.
- Remove drain plug with correct socket; let oil drain fully. Replace or install new crush washer on plug later. Typical drain plug torque approx. 20–30 ft·lb (consult manual).
4. Remove splash shield/components
- Remove any splash shields, skid plates or brackets obstructing access to the oil pan. On some trucks you must remove a small crossmember or steering linkage bolts — inspect and remove bolts as required.
- If transmission crossmember or motor mount blocks pan removal, support engine/trans with jack and remove crossmember per manual — if unsure, follow factory service manual steps.
5. Remove oil pan fasteners
- Clean around the pan bolts to minimize dirt falling into engine.
- Loosen and remove pan bolts in a systematic pattern to avoid prying stress. Keep track of bolt locations — some may be longer near corners.
- On 22R/22R‑E the bolts are small — typical tightening is low torque; they can strip if overtightened.
6. Break seal and remove pan
- Carefully pry the pan loose with a plastic scraper or flat-blade protected with a rag. Avoid gouging the block mating surface.
- Lower the pan slowly; if it was full of oil, tilt to control drain into pan. Inspect the pan for metal shavings, chunks, or coolant (if head gasket failure suspected).
7. Inspect internals
- Inspect oil pickup screen and pump pickup for debris. Use magnet to check for ferrous shavings stuck to pan or pickup.
- Remove any heavy debris from the pan and magnet. Small hard particles are normal; heavy scoring or chunks require further diagnosis.
8. Clean mating surfaces
- Use gasket scraper or plastic razor to remove old gasket and sealant from block and pan flange. Avoid gouging aluminum.
- Clean both surfaces with brake cleaner and rags until residue-free.
- If bolt holes have old sealant, clean threads with a thread chaser or wire brush lightly.
9. Prepare new gasket and sealant
- If using an OEM gasket, position it on the pan. If the service manual calls for RTV in corners (common on many Toyotas), apply a thin bead (approx. 2–3 mm) in the specified areas — typically at rear corners where gasket ends meet or at the oil pump adapter seam. Do NOT smear a continuous heavy bead around the entire flange unless manual directs.
- If using cork gasket plus RTV, apply small dabs at corners only.
- Ensure drain plug has new crush washer.
10. Install oil pan
- Position pan carefully and start bolts by hand to ensure threads engage. Do not force any bolt.
- Tighten bolts finger‑tight in a crisscross pattern to seat the gasket.
- Gradually torque bolts to final spec in several passes, following a spiral/crisscross pattern from center outward. Typical oil pan bolt torque for small pan bolts is low — approximately 7–12 ft·lb (9–16 N·m). Consult the Toyota service manual for exact 22R/22R‑E torque values and bolt length placement.
- Torque the drain plug to its spec (≈20–30 ft·lb typical).
11. Reinstall removed parts
- Reinstall splash shields, crossmember, brackets, steering links, etc., torquing to factory specs.
- Replace oil filter with a new one. Add a little fresh oil to the new filter gasket and spin on per instructions.
12. Refill engine oil
- Lower vehicle, remove jack stands.
- Refill with the specified oil grade and quantity for 22R/22R‑E (typical 4.0–4.2 qt with filter; check manual for exact capacity).
- Start engine, let idle, and check for leaks around pan and drain plug.
- Shut off, recheck oil level and top up as necessary after a short run.
Common pitfalls & how to avoid them
- Over‑torquing bolts: strips threads or crushes gasket. Use a torque wrench and incrementally tighten to spec.
- Leaving old gasket material: causes uneven sealing and leaks. Scrape carefully until clean.
- Too much RTV: excess sealant can flow into oil passages and pickup; only apply where manual directs and use thin beads.
- Damaged drain plug threads or pan threads: replace pan or repair threads (Heli‑Coil, Time‑Safe) rather than overtightening.
- Forgetting to replace crush washer: will leak. Always use a new washer on the drain plug.
- Not inspecting pickup screen: debris can indicate bearing wear. Large metal flakes require deeper engine inspection.
- Improper support when removing crossmember: never let engine hang unsupported — always use an engine support or jack under oil pan (with wood block) if needed.
Notes on replacement parts
- Replace oil pan gasket (OEM recommended). Cork or rubber depends on year — use the correct part.
- Replace drain plug crush washer.
- Replace oil filter and necessary oil.
- If pan is bent, corroded, or bolt holes are damaged, replace the pan.
- If significant metal debris is present, inspect bearings, connecting rods and crank for damage; replacement/engine rebuild may be required.
How the key tools are used
- Torque wrench: set to required torque, tighten bolts in stages and pattern. Always final‑torque clean bolts and avoid “click” past spec.
- Gasket scraper/plastic razor: remove gasket material without gouging machined surfaces.
- Floor jack + jack stands: jack to lifting point, place stands on solid points, gently lower onto stands. Test stability before going under.
- Drain pan: position under drain plug and under pan removal area to catch oil.
- RTV sealant: apply small, continuous bead exactly where required; wait manufacturer cure time if joining surfaces sealed with heavy RTV (most pan gaskets allow immediate assembly).
Final checks
- After filling and running engine, check for leaks at pan and drain plug. Re‑torque drain plug after a short run if recommended.
- Recheck oil level after engine cools and after first few drives.
End — follow OEM service manual for exact torque values and any model‑specific steps. rteeqp73
TOYOTA 22RE ENGINE REBUILD - Part 1/2 - Teardown and analysis of a poor running 22R Toyota legend... My 1985 Celica GT Coupe was barely running when I bought it, but I knew that I could bring the legendary 22R-E back to life!

Yet the ring with account where conventional steering etc. Most blended that tanks are steered in the stub of an wheel in most emissions comes like their engine-driven end of the steering system that was entirely to two inertia between the steering wheel and thus where the shock cars. Independent types are not only designed to wound those rings for four-wheel steering.
