Jessica 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. cause rods never knock lol Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

dfoland93 Posted July 8, 2014 Report Share Posted July 8, 2014 So i just went through this recently. My car is known for rod knock and i have used thicker oil to where the knock is almost gone. I ran into the same problem you have, sadly it was my bearings and crankshaft. Take off your lower oil pan and check out your bearings just to check it out. No oil it usually ruins the bearings and over time it can ruin the crank. The spot with least resistance LOL. I would ground to a rubber dildo if it had less resistance than a run of 4/0 wiring. how many poeple work there 3 or 4 lol At crescendo HQ? probably 2-3 At the sweatshop in china? 30,000 children No Engine Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted July 8, 2014 Report Share Posted July 8, 2014 Ticks are lifter noise and knocks are rod bearings. A knock or a tick can be many things they are not just limited to rods and lifters. Just recently I worked on a Ford windstar for a friend it had one of the worst ticks you've ever heard. Anybody want to guess what it was? I'll give you one clue it was not a lifter but the noise was in the top end. 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.

IH8PunkRok Posted July 8, 2014 Author Report Share Posted July 8, 2014 Just gave it a good listen. The knock (and I do say knock not tick) is as pronounced on the bottom of the engine as it is on the top. It is also loudest towards the back of the engine. -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...

Skullz Posted July 8, 2014 Report Share Posted July 8, 2014 Pull the pan and check the connecting rods near the back of the engine first and see if you can feel any excessive play in them. As long as you don't spin a bearing you'll get away with just replacing them with new stock sized bearings. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
OrionStang Posted July 8, 2014 Report Share Posted July 8, 2014 Likely a bearing. Might be able salvage it, depending on what bearings are available for the motor. You'd need thicker ones to compensate for the play created by damage. You need to get the oil pan off and have a Mopar guy check the rod bearings for play.
