The 2022 and newer Subaru WRX uses the FA24DIT, a turbocharged 2.4-liter engine with a sealed oil pan. Some owners and independent shops have found pieces of excess room-temperature-vulcanizing sealant, usually called RTV, in the oil pan or around the oil-pickup screen. That has raised concern that debris could restrict oil flow and contribute to engine damage.

Quick answer: RTV debris has been documented in some FA24 engines, but there is not enough public evidence to say that every 2022+ WRX has a blocked oil pickup or a confirmed factory-wide defect. Finding a small amount of sealant in an oil pan does not by itself prove oil starvation. The sensible response is to check the oil correctly, take oil-pressure or warning-light symptoms seriously, preserve service records, and use a Subaru-qualified shop for deeper inspection when the evidence justifies it.

This is a focused guide to the FA24 oil-pickup concern. For the broader engine picture, see our FA24DIT common problems and reliability guide. For service intervals and model-year maintenance requirements, use the WRX maintenance schedule and the correct Subaru owner manual for the vehicle.

What is the FA24 RTV oil-pickup concern?

RTV is a silicone sealant used to seal engine components where a formed gasket is not used. Subaru uses sealant around parts of the FA24 engine, including the oil-pan sealing surface. If too much sealant is applied, or if cured material separates from the joint, pieces can fall into the oil pan.

The oil pickup draws oil from the pan through a screened opening and sends it to the oil pump. In theory, enough debris in the wrong place could reduce the amount of oil reaching the pump. Reduced oil supply can lower oil pressure and damage bearings, turbocharger components, camshaft hardware, or other lubricated parts.

That describes a possible failure path. It does not prove that every piece of RTV will block the pickup or that every engine showing sealant debris has suffered oil starvation. The pickup design, size and shape of the debris, oil level, engine speed, and operating conditions all affect the outcome.

What evidence exists?

The concern became widely discussed after owners and independent shops posted photographs and videos showing sealant debris in FA24 oil pans and near pickup screens. Some owner reports describe large pieces of material, while others show only small strands or fragments. Independent automotive reporting has also documented the concern while noting that the scale of the risk remains uncertain. The Autopian’s report is a useful summary of the early evidence and its limitations.

Complaint databases and forums are useful for finding patterns that deserve investigation, but they do not measure the failure rate for every WRX. CarComplaints’ 2022 WRX engine reports contain owner allegations about RTV and oil-pickup restriction, not a controlled study of all vehicles sold.

At the time of writing, the existence of owner reports should not be turned into a claim that all FA24 engines are unsafe. Check the vehicle by VIN for open recalls through NHTSA’s recall tool, and ask a Subaru dealer how any applicable campaign or warranty concern should be handled.

What symptoms could indicate an oil-supply problem?

RTV debris may produce no obvious symptom until oil flow is affected. A clean dashboard does not prove that the pickup is free of debris, but the following signs deserve immediate attention:

  • The red oil-pressure warning light comes on while the engine is running.
  • A new deep knocking, tapping, or growling noise rises with engine speed.
  • The engine develops a sudden change in oil pressure, if a reliable pressure gauge is installed.
  • The turbocharger becomes noisy, smokes, or loses power unexpectedly.
  • The engine stalls, seizes, or develops severe drivability problems after an oil warning.
  • The oil filter contains unusual metallic debris or a large amount of sealant material.
  • Oil level falls quickly, especially with smoke, leaks, or a new engine noise.

If the oil-pressure warning light comes on, shut the engine off as soon as it is safe. Do not keep driving to see whether the light clears, and do not assume that adding oil fixes a pressure problem. Towing the car for diagnosis is cheaper than turning a possible oil-supply problem into a complete engine failure.

What does not prove the oil pickup is blocked?

Several observations can be concerning without being conclusive:

  • A single small strand of RTV on an oil-pan edge.
  • A forum photograph from another vehicle.
  • A low oil level without a pressure test or leak inspection.
  • One knock correction or one unusual data-log value.
  • A normal oil-pressure reading at idle without testing the conditions that caused the concern.
  • A clean drain plug or oil filter when the pickup has not been inspected.

These observations may justify a closer look, especially on a new or modified car, but they cannot diagnose a blocked pickup by themselves. The FA24DIT reliability guide covers the other causes of oil use, knock, heat, misfire, and drivability problems that can look similar.

What can an owner check safely?

Start with checks that do not require removing the oil pan or disturbing factory seals.

Check the oil level correctly

Park on level ground and use the procedure in the owner’s manual. Check at a consistent temperature and record the mileage, oil level, and amount added. Subaru’s 2022 WRX warranty and maintenance booklet provides the factory maintenance baseline; use the manual for the exact checking procedure and model year.

Do not overfill the engine in an attempt to protect it from a suspected pickup problem. Too much oil can create separate problems. If the level is low, add the correct oil as specified for the car and investigate why it fell.

Inspect the oil and filter during a normal service

Ask the shop to look for unusual metallic material or sealant debris in the drained oil and filter. This is evidence to document, not a definitive test of pickup flow. Keep photographs, the mileage, oil brand and grade, and the service invoice.

Do not cut open a hot oil filter, scrape debris into the drain pan, or treat a few harmless sealant particles as proof of engine damage. A shop should explain what it found and whether further testing is warranted.

Check for warning signs and recent work

Note whether the concern started after an oil change, engine repair, track day, hard impact, tune, or other service. Check for oil leaks, a damaged oil pan, warning lights, and new mechanical noise. Recent work can identify where to begin, but it does not establish the cause without testing.

How is the oil pickup inspected?

A meaningful inspection of the pickup normally requires access to the oil pan and the pickup screen. On a VB WRX, that is not a casual driveway check. Exhaust, shields, brackets, or other surrounding parts may need to be removed, and the engine must be resealed correctly afterward.

A Subaru-qualified shop should:

  1. Confirm the complaint, warning, noise, or oil-pressure reading before disassembly.
  2. Follow the applicable service information for the exact model year.
  3. Remove the oil pan without spreading debris into the engine or pickup.
  4. Photograph the pan, sealant bead, pickup screen, and any metallic material.
  5. Inspect the pickup, oil pump, pan sealing surfaces, and accessible engine components.
  6. Measure oil pressure and check for damage when the symptoms indicate possible starvation.
  7. Reseal the pan with the correct product, application pattern, cure time, and torque procedure.
  8. Document the repair and retain the removed material for any warranty discussion.

Do not remove the oil pan simply because a forum says every FA24 needs an inspection. Disassembly can create leaks, affect warranty discussions, and make it harder to establish what happened if the work is not documented. On the other hand, a warning light, abnormal noise, metal in the oil, or a confirmed debris finding deserves prompt professional attention.

Should you proactively drop the oil pan?

There is no universal answer. Proactive inspection may be reasonable when a vehicle has an oil-pressure warning, abnormal noise, unusual material found during service, a documented repair concern, or a qualified technician who can explain why the risk is elevated. It is less compelling when the engine has normal oil pressure, no symptoms, consistent service records, and no evidence of unusual debris.

If you are considering inspection on a vehicle still covered by a factory or extended warranty, contact Subaru first. Ask whether the work is authorized, whether a dealer inspection is required, and what documentation must be retained. An independent shop may provide a useful second opinion, but unauthorized disassembly can complicate later warranty conversations.

Is the 2022+ WRX still worth buying?

The RTV discussion should be one part of a used-car inspection, not the only reason to reject every VB WRX. Favor a car with:

  • Complete oil-change and maintenance records.
  • No oil-pressure warning history or unexplained engine noise.
  • A documented stock or professionally calibrated setup.
  • No unknown engine repairs or oil-pan resealing.
  • A clean scan, consistent oil level, and no major leaks.
  • An independent inspection before purchase.

If the seller refuses an independent inspection, cannot explain the tune and maintenance history, or dismisses a warning light or new engine noise, walk away. A documented, healthy car is a better purchase than an undocumented car with a perfect-sounding reputation.

Bottom line

RTV debris in some FA24 oil pans is a legitimate topic for inspection, but the public evidence does not justify saying that every 2022+ WRX has a blocked oil pickup or a guaranteed engine failure. Check the oil, respond immediately to an oil-pressure warning, document unusual material, and use a qualified shop for pressure testing or oil-pan inspection when symptoms or evidence support it.

FA24 RTV Oil Pickup FAQ

Does every 2022+ Subaru WRX have the RTV oil-pickup problem?

No. RTV debris has been documented in some FA24 engines, but there is not enough public evidence to say that every VB WRX has a blocked oil pickup or a confirmed factory-wide defect.

Can RTV clog the FA24 oil pickup?

In theory, loose sealant debris can collect around a screened oil pickup and reduce oil flow. Whether that happens depends on the amount, size, and location of the material, so debris in an oil pan does not automatically prove oil starvation.

What should I do if the oil-pressure light comes on?

Shut the engine off as soon as it is safe and have the car towed for diagnosis. Do not continue driving to see whether the warning clears.

Should I remove the oil pan to check for RTV?

Not automatically. Discuss the concern with a Subaru-qualified shop, especially if there is an oil warning, abnormal noise, metallic debris, or documented sealant material. If the car is under warranty, contact Subaru before authorizing disassembly.

Is the FA24DIT reliable?

A stock or carefully maintained VB WRX can be reliable, but the platform has less long-term history than older Subaru engines. Oil-level history, service records, calibration, heat management, and engine health matter more than a blanket claim about RTV.
