| OK to use regular gas in a 2002 Lexus LS430? | 13Relevance | 5 years ago | Wojcinski | Submit Your Question HERE | |
| According to the manual, my 2002 Lexus needs premium gas. Just watched you video though and am tempted to switch to regular. I had an Infiniti Q45 and for over 14 years ran regular without an issue, thanks. | |||||

| I've heard people say that stop leak plugged up their heater core and they had to replace it. I'd sooner have the leak fixed than use a product. Or use the tracing UV dye. | |||||

| @mountainmanjoe Yes, definitely coolant. The small spots on the garage floor are orange liquid. | |||||

| You can try the bar sealer they sell at AutoZone I've had good luck with that though often it's the water pump and then off and only leak when it's running at higher speeds if you want to find the source put UV coolant die in the system and see where the ultraviolet die comes out while you shine a UV light on it where in yellow sunglasses they make kids for that | |||||
| Answer to: Popping sound in 2004 Lexus LS430 | 13Relevance | 6 years ago | MountainManJoe | Submit Your Question HERE | |
| It could be a lot of things. First take it for a drive somewhere safe like a big open parking lot. Do some turns to the left and right. Go over some bumps. Listen as hard as you can. Try it narrow it down to a particular side and front/back. If you can get a helper to stand outside that's even better. Then I would securely jack up the front of the vehicle, get under, and start yanking on things. wheels, knuckles, control arms, springs, struts, stabilizer bar, steering linkage, axles, the whole motor... until you find it. Listen for pops and feel for excess movement. | |||||

| @mountainmanjoe It's a single pop. As of yet, it has never popped more than once per turn. I did neglect to say that it popped one time in an intersection (when I was going straight) as I went over the crown of the road. I also forgot to say that I've checked the motor mounts and the struts have been checked. | |||||

| Is it a single pop, or a rhythmic popping that increases as you go faster? | |||||

| Here is a longer video showing no knocking when in D gear when ATF is cold and the knocking begins when ATF is heated up. First half of video when ATF is cold there is no knocking. Second half of video, there is the knocking and more frequent at the end of the video as the ATF heats up. Why would increase ATF fluid temperature cause this knocking? | |||||

| @hillbilly Thank you so much for sharing your knowledge and experience. Thanks for your suspicions on the "lock-up" in torque-converter. I will research more in that area. Knocking is noticeable at 1K rpm or less when ATF is warmed up and in gear. I have tried chocking the wheels, engaged parking brake, pressed down on brake pedal, and applied gas slowly while in gear. I notice the knocking is gone if beyond 3K rpm and knocking comes back when below 1K rpm after I let off the gas pedal. The ATF was dirty when I dropped it from the pan. I noticed there was a slight metal deposit goo on the magnets but no shiny metal pieces. Car is low miles at 42K, but has been mainly driven on local streets with hills by my wife. What is a "park pal"? Do you mean the park pawl pin? You think it is loose or broken? What I don't understand is why is it knocking when the ATF is heated up and NO knocking when it is cold. Even tho the knocking is not impacting the drive operation, it's just bugging me. LOL Scotty's voice is echoing in my head to leave it alone and to just drive it. hahaha | |||||

| Well you are on the right track. I'd suspect lock-up in the converter, what's rpm doing during this time? Rock solid? If so, I'd lean away from TC. Low miles and nice car so I would keep an eye on it and if it gets even a tad worse, use that toyo trans guy you've found to take it apart. Um, can't recall if you can see park pal with the pan off....I imagine you looked close and it and the trans was clean as new inside? How much metal in bottom of pan? | |||||
