bgd73 Posted September 14, 2006 Share Posted September 14, 2006 It has been 18 months with my junk yard soob.. my favorite car of all time.93 loyale 2wd n/a 5spd. http://93loyale.50megs.com I even wanted to document it. My worry is the hellacious lower end crank/rod thud. It sounds like a very high compression engine since I have got it.I have never heard an EA82 so loud cylindrically firing, or rpm range, etc. The little buggy is really thumping every cylinder like its on War Emergency Power on a martyrs WW2 mission (<- analogy! too many avaiation video games). Being as I have never seen or heard of an n/a EA82 "throwing a rod".. what is next step for this noise? Will it just spin a bearing? if the noise is rare, is it oil pump? I have ruled out cams, they are calm and quiet. This thud is a heavy one.. crank relatable. I am at 160k, no engine repairs at all. Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted September 14, 2006 Share Posted September 14, 2006 Long time ago, I had similar sound on my EA82 Wagon, it was the Ball Bearin´ of the Timin´ Belt Tensor... then it did stop... and it broke the Belt. I suggest to check it. Other posibility is at the Clutch Bearin´ ... Check if when you press the clutch pedal at Idle, the sound goes... it happens sometimes, (or your subie is Automatic?) Good Luck!

I never thought of that. Clutch did have some probs a year ago in hot summer. I have the 5spd. That could explain not being able to pinpoint exact origin, engine is very strong for its mileage. If an engine bearing wre shot, it would at least be burning more oil, right?..... Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 15, 2006 Share Posted September 15, 2006 Generally, the EA engines will wear out the main bearings first. It will not cause the engine to "burn" any oil. Usually oil burning is caused by valve stem seals in these engines. The rings almost never show any wear at all. The rod bearings can wear as well, but these make a light metallic knock under load, and no noise at all when just idleing under no load. The dull thudding noise points to worn main bearings as a likely cause. Usually they will last a long time this way. I ran an EA81 with bad mains (3 times the upper limit for wear) for over 40,000 miles with that dull knock, and it never gave me any problems. Still running when I recently pulled it for a performance rebuild. Check out the timing belt, and accesorie belt stuff - get a bit of 5/8" heater core hose and use it like a stethescope to your ear to pinpoint the noise.

daeron Posted September 15, 2006 Share Posted September 15, 2006 yah i was thinking to ask if you had used any sort of stethoscope to confirm where the noise is coming from. you mentioned clutch problems; did you change the clutch and re-use a throwout bearing? did you ever see the throwout bearing? crazy weird idea that just popped into my head as i went to hit the post button.... the FLYWHEEL bolts couldnt be loose could they?!??!?

This engine really can do that for a long time. There is no hollows at any given point in a revolution, to defy balance enough to be annoying and loud, self destructing. The cold idle would reveal a sloppy engine, like it is, due to the air not being correct like on a warm engine. I have inquired of this previous to this post. I heard a turbo 1988 soob spark up after sitting a month or more, just as silent and noiseless as I am accustomed to hearing the EA82, and I thought of my sloppy one- still not repairs anywhere on the engine, no waterpump, gaskets, oil pump, nothing. Not even the starter. Something is inevitable, I would assume fuel pump. My old 87 got a bit noisy into cold weather one year from same area this one is, and on a cold October day the fuel pump quit, and then I lost a timing belt at the same time. I am uncertain what to do with this one, as it has been making low end noise cold since I got it. Link to comment Share on other sites More sharing options...
