In simple terms an interference engine gets valves bent when the timing gives way in motion or when it is not in motion and you kick the car and engine rolls.

"valves aren't expensive but the job is" means each valve could cost you not more than 2 to 3k for quality but the job is a tough one, engine has to be brought down opened and dismantled, bent valves removed and Engine internals scrutinized for other faulty components like seals, engine block, piston damage if non then it has to be coupled back exactly with the right torque wrench for bolts . in other words your average Joe doesn't have the required expertise or tools for doing it. The engine though will work but won't last.

We learn everyday.
So when our regular mechos "drop engine" and the "right torque wrench for bolts" is not used na death sentence be that?
What does the "right torque wrench for bolts" mean anyway?

nurey:


Not only bolts, engine internals too have moving parts and vibration occurs, those parts are bolt down in a specific tightness, too loose wahala, too tight wahala.

check the pix below for torque wrench

GCFR696:


I've been enlightened thanks to you.

I was wondering if Honda has any non-interference engines tho (I know you are more of a Nissan guy, but still...)

nurey:


I am certain most if not all engines with timing chain are interference engine.

Every manufacturer has an interference engine and non interference engine, most old engines pre 2000 are non interference not all most.

for every car you are buying just research if it's engine is interference or not. I don't know the designation of every engine I am just an average Joe and I am not a Nissan guy where is that coming from

GCFR696:


Note taken.
Average Joe? OK o
I though you are a Nissan guy from discussions/threads in which you dissed the almighty Mercedes and Germany

nurey:


No no no, didn't diss, just setting the record straight

Baba guru, good day sir,

1: I drive a Toyota Sienna 2000 the gearbox was recently changed, now when I want to change the gear to reverse or any spot the engine shakes which at the same time shakes the car as a whole, someone said the problem is a bad engine seat, please with your experience what could be the problem

2: my steering is hard, a Kareem said it was the PS pipe that passes oil to the steering I changed that but the problem still persist, now he’s saying I have the change the PS rack, that the rack is damaged so the oil is discharging from there

Please any solution to this from your experience?

jceesquare:

1. For the gear I'll suggest 3 things
a.) Check or confirm if engine RPM is high. If yes reduce to normal speed.
b.) Check the level of oil in the gear. If low top up (that's if the gear itself is fine).
c.) Check the seating. Engine and gear.
2. Your power steering needs to be physically inspected by a good technician.
a.) Check the level of fluid.
b.) Check from leaks and replace parts.
c.) If fluid level is okay and there is no leak, listen to whining sound while turning the wheel. Change power steering pump if you hear the whining sound.

Backup007:
I do hear the sound sometimes, how much would it cost me to change the power steering pump for Toyota Sienna 2000?

Dear bosses,

My Toyota Camry 2003 went off twice on the road yesterday. Once on my way to akure and twice while returning.
Usually when I slowed down on some bad spots and after a long distance on all occasions.

It then display check light.

Please what could be responsible and what can I do?

Urgent please because I'll travel again next week.

Thanks a lot

Dear Motor Guru,
I just scanned my 2003 Toyota 4Runner 4.7L V8 and got the following codes: P0330 and P0420.
Please what could have triggered them and what is possible solution. Thanks n anticipation of your response.

[/b][b]Please dear Nairaland Car Gurus,

I need your candid and genuine advice. I'M A LADY. Which of the two ( 2003 Nigerian used corolla or TOKUNBO 2002 corolla )do I go for AS A FIRST CAR? Considering the nature of our roads, durability, fuel economy, and sleekness
I think both of them are of the same price.


Thanks

Catalyst is losing its capacity to ensure exhaust gases are rid of NOx emmisions

solutions:

1. Replace catalyst with a new unit (expensive)
2. Use an Oxygen sensor apdator to fool the ECU (cheapest)
3. gut out catalyst (AND DO NOT PUT WIRE GAUZE INSIDE). Engine will sound louder
