Question about 1998 Jeep Wrangler

2 Answers

Loud clink/clanking noise starts only after 1998 Wrangler warms up after long idling and then quiets when placed in park, while setting in driveway. After vehicle sets and cools it is fine. Runs and sounds great until it gets warmed up especially on these hot days.

    I wonder if it could be torque converter? I first thought it was a/c compressor but put charge with oil in and apparently not it.

Your oil is thinning out too much. Lucas oil additive would be a great thing for this or an oil change with a little heavier weight oil The other cause of this could be piston slap from low grade fuels.

First you have to locate the source of noise, with a long screw driver, touching the tip on the engine and the handle on your ear. You can use a needle stethoscope too. If you have a loud clink/clanking noise, and the source is the lower part of engine, and increases as you increases the RPM, then might be a crank shaft problem. This worsen and can be cured by rebuilding the engine.

Clanking noise coming from Allison Transmission on a 2001 Chrevrolet Silverado 8.1 Liter engine


this does sound like theres a loose line tapping the engine/frame,during warm up the engine idles faster which could make it vibrate faster causing the the clanking or tapping noise,if this has started after trans fluid change,then check the lines running from the trani to radiator sometimes the service person might bang into something causing plastic clips that hold the lines to break,try getting under it and have someone start the truck and listen to see where it's coming from also hold the lines & see if the noise stops,the service guy could have unbolted something & never put the bolt back causing the clank ex.line may have a clip holding it thats bolted to the trani pan ?good luck

The thermostat is likley stuck open. that means that you are trying to warm the water in the engine block and the radiator also. With the thermostat closed before it allows the water in the block to heat up. When it reaches the desired temp for it to open it then will allow the water from the radiator to flow to the block thus regulating the temp in the block.

1998 Honda Accord. Loud clunk when shifting from Park to Reverse. Noticeable when on a slope "driveway" and fairly quiet when the car is level. Does not slip gears and changes fast. The tranny is going is...


This is kind of normal. All of the weight of the car is resting on the parking lock. when parking on a slope first engage the parking brake then put car in park. This will take the load off of the parking lock in the tranny. when leaving put car in gear first then release the parking brake. I hope this helps.

Oil pressure light on at idle


Don't delay on this. Take the vehicle in and have the oil pressure sensor checked. It could be just the sensor or it could be something more serious. A drop in oil pressure could lead to catastrophic engine failure.
