Q&A

Vehicle Application: 2003 Hyundai Elantra GLS 2.0L

Customer Concern: Front crank seal repeat failures, pushing out.
Tests/Procedures: 1. Check crank case pressure (blow by) at wide open throttle.

2. Check and clean the drain hole in the oil pump housing at about the 6 o'clock position just behind the seal.
Potential Causes: Excessive Blow-By
Restricted Seal Drain

This is just a suggestion, unless you already know you have crankshaft damage.

Is it a 'per se' problem? Not to my knowledge or experience.

A lot of issues are the result of HOW a vehicle is used or maintained. My first question is: Is this a manual transmission? Second: Do you depress the clutch pedal when stopped or at stop lights? Third: Is the oil changed at the correct time and a high quality oil used?

The main factor to excessive crank end play will be the load exerted on the crank while the clutch is depressed. The force can easily be over 1,000 lbs, often closer to 2,000 lbs. A thrust bearing can only take so much, combined with used oil will make it wear down faster.

Korean cars are designed and built to undercut the higher quality Japanese vehicles. What was saved in it's purchase is now requiring the second payment, as it were.

this happened to me on my 04 elantra gt at 118,000 kms replaced seal and new one immediately blew. estimated 1/4 of play in crankshaft. only option rebuild bottom end or replace motor. cheaper to rplace motor. problem documented on justanswer.com

found out owner never changed oil !!!. pressure regulator plunger was stuck causing full oil pressure !! dropped pan. thrust bearing and endplay O.K. replaced oil pump and problem solved !!! dont let them sell u a not needed motor.

g o buy a brand new f150 and use it push old car off a cliff
