OrionStang Posted July 8, 2014 Report Share Posted July 8, 2014 Damn dude. Just baby it then, and start saving for a motor. Probably some issues in there, especially with the track runs and long highway trips. SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted July 8, 2014 Report Share Posted July 8, 2014 Could be a stuck lifter then. What oil weight do you run right now? That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

SnowDrifter Posted July 8, 2014 Report Share Posted July 8, 2014 Little trick if you don't have a stethoscope: Grab a socket extension, press it to a part of the engine, ear next to the other end.

OrionStang Posted July 8, 2014 Report Share Posted July 8, 2014 Also it appears to be coming from the top of the engine You may be lucky, and the knock is just from the heads. But running it hard on low oil like you may have done, most likely caused damage in the low end as well.

OrionStang Posted July 8, 2014 Report Share Posted July 8, 2014 I'd suggest just driving it 'til it dies. I've had a few 'beaters' in my life that knocked in one way or another for years. It could last a while, or not LOL. SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
Jessica Posted July 8, 2014 Report Share Posted July 8, 2014 well, normally a tap is from top engine and a knock is bottom engine, but all these modern engines sound kinda hollow anyway. Could be hard to tell unless you do like snowdrifter said Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.

OrionStang Posted July 8, 2014 Report Share Posted July 8, 2014 If you dont use premium already, try a fillup with 93 or 91, whatever you got there. Since Duck wants to get all technical, a true knock is a combustion related issue, not a mechanical one. Also known as pre-detonantion. Higher octane fuels can sometimes cure this.

outbumpinghicks Posted July 8, 2014 Report Share Posted July 8, 2014 I would say a lifter tick. If you do 7 passes and that long of a drive without noticing any noise, chances are you pushed any oil that was equal to or above the rear main seal level out and that is why you didn't notice a leak before doing the drive and passes. It's possible you just have a stuck lifter. I would do the rear main, fill it up with an oil a weight above, and see if the noise is still there. Possible if you have a timing chain, one of the tensioners, guides, etc ran a little dry and ate up a bit of the sprocket teeth and/or a bit of chain causing a little slack resulting in the chatter you hear. One person mentioned running a synthetic blend, that wouldn't be a bad idea IF you already run synthetic. Switching over on a motor that is used to conventional after such a long time can cause more harm then good. Only time I run synthetic is if I rebuild a motor. Conv for a few thousand miles for break in, then switch to synthetic right away. Just my .02 cents though. Best of luck! Link to comment Share on other sites More sharing options...
