Is Your Porsche’s Rear Main Seal Leaking? Get It Fixed in Humble, TX!
Although Porsches are sleek, powerful vehicles, they are notorious for experiencing issues with their rear main seals (RMS). The rear main seal is a critical engine component in Porsche sports cars and SUVs, preventing oil leaks where the crankshaft meets the transmission. RMS failure is a well-known issue, particularly in Porsche models, leading to oil leaks, increased oil consumption, and potential engine damage. Because the rear main seal plays a key role in keeping your Porsche’s oil flowing correctly, a faulty seal can have serious consequences for your vehicle’s performance.
In extreme cases, problems with the RMS could lead to contamination of the vehicle’s clutch friction plate. Consequently, you will suffer from poor gear selection and reduced all-around performance. All Porsche owners must understand how to identify and repair rear main seal leaks. To help you with this, Motorwerks Auto Group, located near you in Humble, Texas (TX), has everything you need to know about the common causes and symptoms of rear primary seal failure.
The Rear Main Seal and Its Purpose in Your Porsche
The rear main seal is located at the back of the engine, sealing the crankshaft as it exits the engine block. It prevents engine oil from leaking out while allowing the crankshaft to rotate freely. If the Rear Main Seal deteriorates, oil leaks between the engine and the transmission bell housing, which can cause long-term issues such as low oil levels and clutch contamination. Additionally, it ensures explicitly that your Porsche’s crankshaft and transmission stay properly lubricated. As such, a rear primary seal failure can cause oil to leak out at a surprising rate, which may inflict a significant amount of damage upon your vehicle’s engine.
3 Common Causes of Rear Main Seal Oil Leaks in Your Porsche in Humble, TX
1. Contaminated Engine Oil
One of the most common causes of rear main seal leaks is irregularities within engine oil. If your Porsche’s oil is contaminated or running low, the rear main seal may dry out and become stiff, potentially causing it to crack. This can lead to oil leaks. As such, you must regularly change and refill your Porsche’s oil. Get your oil checked by any of our ASE-certified technicians at Motorwerks Auto Group, located near you in Humble, TX.
2. Worn-Out Main Bearings
Similarly, another preventable cause of rear main seal oil leaks is worn main bearings. Your vehicle’s main bearings are designed to keep its crankshaft properly aligned, but over time, these bearings may wear down. This will allow the crankshaft to move improperly, which can damage or stretch out the rear main seal. To prevent this from happening, you should regularly take your vehicle in for routine services to expert technicians, such as those in our shop located near you in Houston, TX. By doing so, your mechanic can replace worn main bearings before they cause bigger problems.
3. Blocked PVC
The third common cause of rear main seal oil leaks is a blocked Positive Crankcase Ventilation System (PCV). The PCV is responsible for maintaining an adequate amount of air pressure on the crankshaft and its adjacent parts. If this system becomes clogged, the air pressure may grow too strong, causing stress to the crankshaft and the rear main seal. Eventually, this may cause the rear main seal to rupture. Much like worn main bearings, this problem can also be prevented by ensuring that your Porsche receives regular maintenance. Drive into any of our garages located near you in The Woodlands and Spring, TX, to get your Porsche’s regular maintenance. If you notice oil puddles under your vehicle, contact us immediately.
