Why is my Jabiru Engine running too hot?
- F
  fletcherkennethAug 22, 2025
  If your Jabiru Engine runs too hot, with oil temperature above 110°C (230°F), there are several possible causes. Check the oil level; too much or too little oil in the crankcase can cause overheating, so adjust as necessary. Poor quality oil can also lead to this issue, so consider an oil change using the specified oil. A clogged oil filter restricts oil flow, so change the filter. Excessive piston blow-by, often due to worn or sticking piston rings, may require a complete engine overhaul. Faulty bearings can also contribute to overheating; if metallic particles are present in the oil, a complete engine overhaul is necessary. Lastly, a faulty oil temperature gauge can give a false reading, so consider exchanging the gauge.

  If your Jabiru Engine runs erratically or misfires occasionally, consider these possible causes: * **Spark plug failure:** Check the plugs, clean inside and outside, and adjust the electrode gap. If necessary, replace the plugs. * **Faulty HT leads:** Dry any damp leads and replace damaged leads. * **Faulty ignition unit:** Replace the ignition unit. * **Clogged fuel filter:** Replace the fuel filter.

  If your Jabiru Engine is running erratically or misfiring occasionally, there are a few potential causes. Start by checking the spark plugs. Clean them inside and out, adjust the electrode gap, and replace if necessary. Inspect the high tension (HT) leads; dry any damp leads and replace any that are damaged. A faulty ignition unit can also cause misfires, so consider replacing it. Ensure the fuel filter isn't clogged by renewing it. Finally, check that the carburettor sense tube is connected; this tube helps control the fuel mixture and should connect the small nipple on the carburettor to a fitting in the filtered side of the carburettor heat box.

Why is the oil pressure low on my Jabiru 3300?
- L
  Lori WilliamsAug 31, 2025
  If the oil pressure in your Jabiru Engine is low, start by checking the oil level in the sump and replenish as necessary. High oil temperature can also cause low oil pressure, so ensure the engine isn't overfilled with oil and check for proper installation gaps to maintain airflow. Inspect the pressure gauge, sender, and wiring for faults, and renew as necessary. Faulty crankshaft bearings can lead to low oil pressure, potentially requiring an engine overhaul. Lastly, inspect the relief valve for proper sealing; foreign matter stuck in the valve can cause low pressure, so clean and replace it.

Why does my Jabiru 3300 Engine keep running with the ignition off?
- S
  Steven ShafferSep 2, 2025
  If your Jabiru Engine continues to run even after the ignition is turned off, several issues might be responsible. First, check the idle speed and adjust it to the proper level (900 RPM). A faulty ignition switch can also cause this problem, so inspect the switch and cables, repairing or replacing them as necessary. Finally, an overheated engine can continue running, so conduct a cooling run at 900 RPM to address this.

Why is my Jabiru 3300 Engine idling unsteadily with smoky exhaust?
- M
  Marc StoneSep 4, 2025
  If your Jabiru Engine idles unsteadily after the warm-up period and produces smoky exhaust, there are a few potential causes. Ensure the choke is fully closed, as an activated choke can cause these symptoms. A dirty, jammed, or worn float valve can also lead to unsteady idling, so clean or renew the float valve. Lastly, check for an intake manifold leak, tightening all connections and replacing any faulty items.

What causes a CHT reading error on a Jabiru 3300 Engine?
- J
  jason10Sep 5, 2025
  If you're experiencing a CHT (Cylinder Head Temperature) reading error on your Jabiru Engine, start by checking the gauge, sender, and their connections. Replace them with known good items if possible, and try reversing the polarity between the gauge and sender to re-test. Verify the original reading using a second thermometer, such as a hand-held infrared thermometer, to confirm if the temperatures are improper. Also, consider the cold junction temperature; the standard gauges assume the cold junction is around 25°C, so ensure the junction isn't exposed to excessively hot or cold air for best results.

Why does the oil collector bottle on the firewall fill quickly in my Jabiru Engine?
- H
  huntwalterSep 7, 2025
  If you notice the oil collector bottle on the firewall of your Jabiru Engine filling quickly, it could be due to several reasons. Worn, broken, or wrongly fitted piston rings can cause this issue, potentially requiring repair or an engine overhaul. An incorrect oil grade can also contribute, so perform an oil change using the specified oil. Worn or distorted cylinders may also be the cause, again potentially requiring repair or an engine overhaul. Over-filling the sump can lead to this problem, so reduce the oil level in the sump. Finally, negative-g conditions, which the Jabiru Engine is not approved for, or strong turbulence can have a similar effect; reduce RPM/speed when operating in strong turbulence.

What causes excessive oil consumption in a Jabiru 3300?
- A
  Alexander BlakeSep 9, 2025
  Excessive oil consumption in your Jabiru Engine can stem from several causes. Worn, broken, or wrongly fitted piston rings are a primary suspect, necessitating repair or an engine overhaul. Poor oil quality can also contribute, so perform an oil change using the specified oil. Worn valve guides may be the issue, requiring repair of the cylinder head. Lastly, check for any oil leaks and seal them.

What causes excessive vibration in my Jabiru 3300?
- B
  Briana HicksSep 12, 2025
  Excessive vibration in your Jabiru Engine can arise from several sources. Begin by checking if the propeller is out of balance and balance it according to the manufacturer’s instructions. Ensure the propeller tip tracking is within tolerance, adjusting as necessary. Uneven propeller blade pitch can also cause vibration, so check and adjust the blade pitch. Check the spinner for balance and adjust if needed. An unsuitable propeller can lead to vibration, so replace it, with quality 2-bladed fixed pitch wooden types recommended. Incorrect tuning can contribute, so check and adjust the carburettor. Finally, ensure that engine components like air ducts, exhaust, and the oil cooler aren't rubbing on cowls or the fuselage.
