The description given by the OP sounds like an electrical fault to me. Try to visually inspect your car for any loose wires or connections & beware of those roadside |

smartchoice: +234 802 949 8260 Oh thanks bro, bless you real good! I had to find a way to help this OP (I think he's the person whose lexus's engine got stalled on the expressway from Lagos), he spent a 10min call to me during the weekend because of this case. |

GAZZUZZ: OP I think you should give more details, engines don't just knock like that.... Car was serviced two days ago and even after the incident,There was still oil so I'm equally at a loss as to how this could happen without warning. @Smartchoice,Thankl you for the digits.I would try calling the number tomorrow during regular working hours |
| Re: Is My Lexus RX300 Engine Bad? by Top9jajamz: 9:07pm On Sep 08, 2014 |
lomomike: Thank you for your effort sir,I am the one described in the quote above.I'll definitely give SITREP as soon as progress is made. |

@OP: Bought mine last month(2001 RX300). I think what happened to me is what is being replicated here.The metallic ring attached to the car key MUST NOT rest/pressed on the transponder(the black rubber base of the key) while turning the key in the ignition when starting the car. I had a similar issue which was brought to the attention of my age long technician and he said I have to change the car's ignition.I was trying to work out a visit for the change when my wifey pointed out this instruction from the car's manual which I had abandoned inside the glove compartment. Till date, the issue has been resolved. Try this before getting a mechanic sir. If it doesn't work, then get the car scanned. 1 Like |

Where's the location of the Vehicle. It's not impossible that the engine could get knocked just like that but some things would have caused it. With your mechanic turning your crankshaft without turning, I guess he's right but you can seek a second opinion though. However, if that's the case, you don't have to change the engine but to change the metals and rings and you can be assured your SUV will be back on the road. Should you need any more assistance, kindly call me on 08099919361. Regards |

What did the car tell you si wrong with it? ie scan it first. If the lights is dying you have electrical problem somewhere it wont start. Your mechanic did service the car now it won't run call him and ask him exactly what he did step by step, he could have loosened a bolt or sensor and left it off. Cars just don't die without usual sounds |
| Re: Is My Lexus RX300 Engine Bad? by Top9jajamz: 12:45pm On Sep 10, 2014 |
Updates: A second opinion from a mechanic recommended by a Nlander confirms the Engine is indeed gone. Going to Ladipo to source for a new engine. Thank you guys for your contributions. Still a mystery how an Engine could just die without signs. |

The knock sensors probably were bad long before u bought it while previous owner was using it. |

chukel: The knock sensors probably were bad long before u bought it while previous owner was using it. That sounds very logical, the car got stuck in 3gear without the driver noticing and he was probably doing 6000rmp at 120km/hr, that's an engine killer! |

0rex: The description given by the OP sounds like an electrical fault to me. Try to visually inspect your car for any loose wires or connections & beware of those roadside clowns. This is no electrical fault. I know of no electrical fault that would prevent the crankshaft from rotating freely, with a wrench on the crank bolt. Sounds more like major mechanical failure. I would hazard a guess - the crankshaft main bearings have melted, either through low oil, or a bad oil pump, leading to catastrophic loss of oil pressure. The bearings can actually get welded to the crank journals. The same can occur is the camshafts are starved of oil. They will seize in the cylinder head bearings. The Nigerian mechanic you're calling a "clown" did the right thing - he removed the starter motor, then attempted to rotate the crank with a wrench. The crank failed to rotate. In my opinion, that test is conclusive of mechanical failure. A car travelling at 70 mph will be doing approximately 3,000 rpm in 5th (or 6th) with a manual transmission. If the oil pump fails at that speed, the oil pressure warning light will illuminate. Regardless of how quickly you shut down the engine, and dip the clutch, the crank will be ruined. So it's not unusual the way this guy's car died on him. 2 Likes |

chukel: The knock sensors probably were bad long before u bought it while previous owner was using it. Are you kidding me?? Knock sensors do NOT detect the sort of knock you're thinking of. They detect detonation caused by poor quality / low octane gasoline, and retàrd the ignition timing, until the detonation ceases. 1 Like |

I don't know why some people keep calling our local mechanics CLOWNS. They do come in handy one time or the other. These are people without any formal education yet they are able to convert a right hand drive vehicle to left hand drive. They lack any formal education but they can still transplant a Toyota Camry engine into a Landrover Freelander. Yes the normal thing is to take our cars to a reputable shop, but how many of those shops are readily available. How many people can afford their fees. I once took my car to a Honda shop, after scanning the quoted 490,000 naira as total cost to fix the car. This does not even include opening of the engine. I was told after the fix is done and the problem persist then they will drop the engine which will cost another money. You won't believe the parts they listed: ecu ecu programming ABS module (because my ABS light was on) 4 ABS speed sensors catalytic converter o2 sensors MAF sensor Throttle body Baro sensor etc etc. Then my engine was shorting fuel. So what did I do.. I went to one of the so called 'clowns'. I bought a used engine for 170k, bought o2 sensors and space to fool my ecu, bought abs sensors (I never changed the ecu and abs module and some of the things I was asked to change at the 'reputable shop' Well at the end of the day I spent less than 230k and my car has been ok for more than one year now. The thing is to have a scanner and scan ur cars, then go to a mechanic tell him what u want him to do. You can't call all of them clowns because to be sincere they are trying considering the level of formal education they have. If I had stuck with Honda, I am sure after spending 490,000 naira at the end they would tell me the engine needs to be dropped and would cost an additional 150k or more because I don't see how replacing all those sensors would stop my engine from shorting oil. 3 Likes |

Siena:Thanks for the explanation, I guess I was wrong. I have always been a silent fan of yours & have never had a cause to regret it. Although some of those roadside mechanics could present like clowns sometimes, I meant no disrespect to them in entirety in my previous post because some of them actually know their onions as rightly stated by abatically. |

Siena: A bad knock sensor in a 1mz engine will in most cases stop the car from switching to 4th and 5th gears (automatic transmission) if the OP had been driving with a bad knock sensor and failed to notice he was on 3rd gear at very high speeds engine would fry quicker. |
| Re: Is My Lexus RX300 Engine Bad? by drhappy(m): 10:12pm On Sep 13, 2014 |
@:modestdude: lemme apologise about my late response.I got mine from Cotonou too and I went there myself.You must be prepared to go yourself with a trusted hand.You don't even need to take much cash.With 20k you can first secure the car of your choice and go back to sort out the balance and delivery at your convenience.Am not a professional car dealer though. |

Are you kidding me?? Knock sensors do NOT detect the sort of knock you're thinking of. They detect detonation caused by poor quality / low octane gasoline, and retàrd the ignition timing, until the detonation ceases. @Siena:Been wanting to raise this issue with you boss.Bought this Nissan Xterra 2002 model last month together with my RX300.Every was fine with it until about 2 weeks ago,when the Service engine soon light was coming on intermittently for about 3days the become permanent afterward.Scanning threw up the knock sensor error code and the guy said he wanted to remove the sensor but I had to fix an appointment as the sensor was hidden somewhere within the engine.I got in touch with NISSPART, bought the specified engine and gear oils from him and narrated the situation but he told me not to worry as most of those xterras I see in Naija have the Service engine soon lights on due to bad fuel in this country as corroborated by you and that they respond poorly to fuel addictives.My madam uses it for her weekly itinerary(work,drop and pick kids from school,shopping and church).No distant journey. Just seeking a third expert opinion,can she continue using the car? |

Agreed. My post was referring to the knock sensors being related to an engine "knocking", then seizing up. |

Thank you all for your contributions,I've learnt something from each post. I finally got the engine fixed however its not as silent in idle running condition as observed by the driver who drove the vehicle initially when it "knocked". The Mechanic advised me not to turn on the AC for at least 5 Days to allow the engine acclimatize to its new body(Your opinion on this is needed) However i realized that there's a discomforting noise coming from the timing belt area in the first 3-5 seconds of raising/accelerating the car. I plan to get this checked out immediately i locate a Lexus repair specialist in Warri here but until then is it advisable for one to use the car and what could the fault be. I noticed that the Door indicator light is permanently On despite the fact that all doors are locked and ignition off. The TRAC OFF light,VSC,CEL, are permanently on.I guess i need to scan the car(please where can I get a person to scan my car in warri) Finally during the engine change,The electrician bypassed the thermostat so that the cooling Fan comes on immediately the engine is switched on rather than when the engine temperature becomes hot. Anyone with previous experience and solution on these issues raised above should please spare me a minute of their time and drop probable solutions. Merci beau coup. |

Top9jajamz: Thank you all for your contributions,I've learnt something from each post. I'd advice you to take the car to a specialist lexus workshop to diagnose the car and know the mixup in the relay/wire harnesses. |
| Re: Is My Lexus RX300 Engine Bad? by chukel(m): 12:21pm On Sep 14, 2014 |
Siena:everybody is learning here. I never mentioned "knocking", then seizing up. I only pointed out the possibility of the knock sensors being bad before he bought d car. Thanks for the info u provided. |

Top9jajamz: It appears you are loaded for allowing that clown to send you back to the market soon to purchase and replace that engine with another. If not, do you really know the implication of abusing your radiator fan to spin constantly as soon as ignition or engine starts? Of course, you didn't do that intentionally because you didn't know. But the truth is, you allowed that clown to do that to that poor vehicle. Look at what the poor vehicle has gone through for few weeks or months it entered Nigeria. It will be strange for a mechanic to mess the factory radiator fan setting and still leave the thermostat in the cooling system. So if I am right that the thermostat was also removed, then the death of that newly purchased engine is been accelerated. Go and asked him if he removed the thermostat or not. Aside high fuel consumption which the abuse of your cooling system will introduce, your 2nd nightmare of loosing another engine is on its way and the countdown is very fast. Ikenna |
