Engine cranking/startup noise (merged threads) - Page 4

PTYIS2 · 02-16-07, 02:53 PM

To me it doesnt happen in the mornings. only during the day after using the car if i let it rest for a few hours (like 4 i guess at that point oil is already at the bottom but its still warm or less dense that when cold in the mornings)

I have been able to fix it by adding more oil, but the problem is that oil level apears to be above that maximun on the oil dipstick. May that be a problem?

I did oil change 1 month ago and the dealer only used 5.5 qtrs, i understand that we should use 6.7, but using 5.5 the dipstick showed to be in the max of oil allowed.

Thanks

FWIW,
I'm getting a lot less noise less frequently with less oil. When I changed the oil at 10K, I put in about 6.6 qts, which showed to be right on the max notch.

I drained enough to where it's showing right in between the min and max notches.

I think I can here it every now and then but it's never been the unmistakable tap, tap, tap, that I was getting before.

Also, the noise seems to be more frequent I'm parked on a slight incline.

I'm not worried about this issue any longer as I've notified my service advisor and he said it's normal.

The noise has been getting much more frequent. It's happening on almost every start up now and even if the car has been sitting for just an hour or so.

I have a message into my SA and I'll let y'all know what he says. Whether there is wear/damage to my engine or not, the noise is actually very annoying and embarassing.

I'll probably go to the 5w20 on the next change though and see if that makes a difference.

do you guys solve the problem yet? becasue i have this problem. it was so offen( like every time i start my car) but now it is gone i think.
since it was so offen to me so my friend help me start my car and i looked under my hood and found it was that thing( i don't know the name) doesn't trun with the bell(like 1-2 sec), and once that thing is truning with the bell and the sound is gone. so does anyone know what is the problem?

I hope this would help.

I had the TSB done about 3 months ago and as of yet the sound never came back. But on the invoice the tech stated, "Improper free play in camshaft gear assymbly. Replaced camshaft gear assymblies on both banks."

On my 07 250 I didn't need to. Just told them I had that problem and they said ok they'll get it done for me. But on this car, to my surprise, they were able to replicate the problem and fixed it within a day.

I put 6.5 quarts in there during the most recent oil change and the noise is gone, I use castro synthetic 5w-20.

ya i got the same noise from my car like after 3k miles. Its like a ticking sound. I might have to make an appointment also.

I have been getting this noise the past couple days as well. My last service at the dealership was for the 15K maintenence, about 3 weeks ago.

It only happens on the first start up of the day and after I get off of work, car sits for about 10 hours. I am not talking about the injectors.

This is a metal clanging sound. Will check oil level tomorrow, better yet, im going to try and get my camera to record the sound.

Redpaste · 01-13-07, 12:37 PM

I think your dealer is giving you the run around. There is something abnormal about the car. It may be the oil level is too low.

I really doubt Toyota/Lexus would roll out a brand new model that made clanking sounds when starting.

anyone with new updates on this? I'm running full syn motul 5w30 and it's starts once in a while during cold start up. im gonna check the dip stick tommrrow (stupid strut bar is in the way) but is the oil level the main problem?

At my last oil change I switched to 5w20 Mobil one and the noise is still there once in a blue moon. It's not a case of low oil either as I'm slightly above the max fill line on the dip stick. Really is unpredictable for me as it can be either warm or cold outside with the same results. Oh well.

I had this happen to me a couple times and it sounds just like a well worn timing chain, worn and leaking tensioner like those on a late model Mazda or Mitsubshi four cylinder engine on start up. This is so old school you would think Toyota would have made a better design by now. I haven't had it now for a long time but I know exactally what you guys are describing and lobux is correct now. Low oil pressure at start up, insufficient chain tension, causing the chain to "wip", once oil pressure is up and proper tension restored,....it's quiet. This happens within seconds.

The timing chain is probably rubbing on the chain slipper and damper.
If I had to move my car on the driveway to let someone out, it would do it on the next start! So now I just go for a five minute drive if I have to move it.

No more noisey timing chain clatter. The dealer changes my oil and they probably use 5w30 dino, I'll check to see what they use next time I go for service.

will this cause any problem in the long run?

If we do not find out what is causing this, i.e. oil type/viscosity, leak down, wear, adjustment or material, we will have to replace tensioners in the future. Of course it depends on if you keep experiencing this, frequency (every start) and for how long. The chain and tensioner should last a long time even with this annoying noise/problem.
