SOURCE: knock in engine

Will831,
Check your timing belt too, it might be loose already. My car had the same problem and thougt that engine was going bad on me. Tried also the additives but didn't help. So I did a litle invistagation to figure out where the knoking sound is comming from. It sounded near where the belts are. Opened the cover and voela! found the belt was loose - took it out - upon invistegation, belt was starting to wear out out - one of the teeth was starting to peel off. Replaced it, retightend it and replaced the belt tensioner too - so far it's been 4month now and still no knocking problem.
Hope this helps..
--Ed

SOURCE: I HAVE 02 TRAILBLAZER LTZ, AND IT JUST STARTED

Hello, I see you have a trailblaber with a knocking noise. It sounds like you have an electric fan clutch issue. Believe it or not your vehicle has an electric fan clutch. It looks just like the older non-electric but if you look on the driver side of the fan shroud that is the wire connector you see. It is an exspensive part just for the clutch but thats exactly what you are describing. It doesn't get louder just fast with rpms. Please rate my answer, Thank you

SOURCE: engine knocking noise in 2000 saab 9-3 SE?

It's a common problem with these cars i am actually fixing mine as of now. That car is all about oil pressure and when it is low you'll start to get a tap and or what sounds like a knock due to the lifters not having enough pressure. Try taking your oil pan off and check your oil pick up line going from the oil pan to the turbo. A lot of times it gets a lot of sludge build up and makes the pressure little to none. If that looks clear check the slump inside the oil pan and see if that has sludge build up. Well hope this helped

Is it Worth to invest for a new timing chain or new engine on my 2007 Chevrolet cobalt?


Hi, The loud knock you are hearing is typically refer to as "spinning a bearing" OK, sounds like that's what is supposed to happen I know, BUT, the bearing is called a shell hearing, it is the bearings that are used in the connecting rod to crank connection.. Now, the repair... it is most common to replace the engine in these cases. You can expect around $3000.00 to $ 3500.00, replace the engine.

1989 honda prelude si. Automatic,shakes real bad when stopped.has no power,pedal to floor barely goes over 30 mph. Smells of fuel,i removed the cat now car,starts at least,but still wants to die and rough...


If the shaking has been progressively getting worse i would start by checking the engine and transmission mounts for rips or tears. Smelling fuel and major loss of power would suggest that you have a fuel leak somewhere. The sending unit its self is a culprit that can be hard to locate so if in doubt check it as well.

1994 Honda Prelude si starting problems


Your starter motor is either not getting power or in need of replacement. Otherwise, there is nothing wrong with your car.

Also check your battery connections for no corrosion there as well as by the starter motor. Low voltage circuits in a car are extremely vulnerable to poor contact issues.

1979 cad fleetwood brougham knocking sound from,engine


Sometimes collapsed lifters or loose rocker arms can cause knocking sounds in an engine. However, the fact that there was a possible loss of oil pressure and that the knocking gets louder as the rpm's increase, would indicate that there is damage to a connecting rod bearing and possibly the crankshaft. If the latter is the case you are looking at a fairly substantial repair bill.

95 prelude -- dash lights for speedometer and tach are out


Just fixed this myself. I found a used USDM meter/gauge out of a 1995 SI on EBAY for $200. However, I have a VTEC engine that redlines at 7500 RPM and the SI's redlines at 6500 RPM. Easy to fix by swapping the face plates inside of the meter/gauge. If your issue is the bulbs they cost a lot... around $250 each. But if your lights went out simultaneously then the bulbs are not the issue... it's the power supply where the bulbs plug into and that's located behind the drivers dash speaker (very easy to remove with only two screws holding it in). This part is more expensive at around $350, but cheaper than buying two bulbs. Scroll through every page of honda prelude listings on EBAY and you may just get lucky like I did. Hope this helps.
