Hay all

I got a wierd problem when i start my car up in the morning i get the tappet sound for a couple seconds then it goes away like normal. But sometimes the tappet sound will stay there for a while but when i turn the car off and on again it will sometimes go away all togethor. Like something to do with the oil circulation.?
Oil is always full dosent even use oil and always clean oil replaced every 5000km plus filter
Thanks Kurt

your right. You are a genius. Its the oil that hasnt reached the top of the engine when its cold so it will be tappey for a few seconds till the oil gets there.:) Very common in cooler weather or as the oil gets thicker.:)

Na mate your wrong it does it sometimes when its warm until i turn the car off and on it will totally disapear. And will never happen for months then come back again its wierd.

i thought this was a standard magna "feature" :)

Like i said. With the cooler weather and your oil starting to thicken up it will happen. If its doing when your car is warm and running you have a major issue you need to check as there might me blocked oil gallerys.

I heard something about this being the hydraulic tensioner for the cam belt. I'll see if I can dig up some info

Are you thinking about on a first gen?

Din, ding, ding, ding......We have a winner!

I dont see how the tensioner can caue it as its just tensions up the belt so it doesnt skip a tooth and bend your valves.

My pajero is tappey for about 3 seconds when i start here up. common for an old motor and its happens plenty more n the cold weather as oil is thicker when its cold and thin when its hot. The tapping is no oil up the top to lube it, So it noise till the oil gets there.

Oh I understand about the lifters rattling for a few seconds until oil pressure builds up.
What I was thinking of is different. I remember reading about a fault where it would continue rattling but if you stopped the engine then restarted it would go away. Anyone shed some light on this?

EDIT: Found it, I was thinking of this thread,

There's the normal tappet sound.

Then there's a similar sound from low oil pressure.

Sound very similar. I've found low oil pressure to be a slightly higher pitch than the normal tappet sound.

Now - take the following with a grain of salt, this is just my observations:

Low oil pressure will happen in colder climates (thicker oil as per Ego's suggestion). If you turn the car off/on, pressure is back to normal.

Really gotta fit an oil pressure guage....

Yeah this is really pissing me off i started my car warmed it up turned it on and off about 7 times let it idle. The tappet sound was there left it. Then next morning cold and started car up tappet sound for 2 secs like normal and gone like normal again WTF.?

Bump wat are people thoughts.?

If its tappets - you can have them replaced, the tappets are worth bugger all - its the labour thats the killer.

If its low oil pressure - only way to tell is to hook up an oil pressure gauge and find out.

K bro sounds ok. But it sounds like my tensioner though cause this happens of turning my car off and on sometimes.

:tired:

How many km has the car done? was the tentioner ever replaced?

Wow, the opinions here astound me sometimes

If it is a top end sound it is the tappets. What happens is there is a minute little valve inside each lash adjuster, these get dirty and the little spring loses tension and the oil bleeds out of the valves that are compressed at the time the engine is stopped, this will happen when warm or cold in general Sometimes you may be fortunate for a better adjuster to be that one on pressure thus less tap thus the sound does not last as long. The cause often for the grit and gum to get in them is also there are little bleed holes on top of each rocker and these block not allowing the oil to pass through and flush out the tappets. Another common mistake is people replace the tappets and do not clean the rails and oil supply is insufficient.

With the belt and the tensioner, this is also a well known problem you will hear only when cold. It is actually the tensioner pulley and the greese gets old and hard, when it starts to spin up and warms up, the noise goes due to better lubrication. The myth is that it is actually the hydrolic tensioner however the when the tensioner pulley is replaced the belt is reset and all good. THis is not as common and to be honest I am yet to see a hydrolic tensioner that really needed replacing. Always the pulleys should be done when a belt gets done

Show off. for us simple people, like i said lack of oil when cold..:P

No, inability to hold pressure within the lash adjuster when there is no oil pressure, this motor like many will generally do this regarless if cold or hot, it is more time dependant than temp depandant :)

One solution if the problem is not too bad is to get a good oil system cleaner and give the engine a really good flush, do an oil change and try Penrite HPR10 or similar

Mal one question which I cannot remember being asked....

Is there any future problems with letting this issue slide? I mean, will this small problem cause a bigger more expensive problem down the road?

Not really, if you keep the car serviced like you should and the noise is only on start up you will generally be fine when it comes to lash adjusters. Eventually they will become noisy more of the time and like anything will need replacing

WIth the tensioner, if you are only a few thousand k's off getting a belt done, you should be ok, if you are far from getting it done, might be an idea to look at an early belt job as you do not want the idler pulley to lock up

Remember the idler pulley on the tensioner side (rear one) does not have much pressure on it when the engine is running as it is on the back of the belt, it is the front one that holds and deflects the belt.

Cheers,

My tentioner is fine, just the lash adjusters - I find they actually get more noisy towards the service interval (6500km on Penrite HPR5). Change the oil and they make noise for maybe 10 seconds when cold.

it is more time dependant than time depandant :)

I think you made a boo boo in that line.:P

Tell me more about this. What is the process.? I take it its some you replace the oil with to flush then drain.?

Get a good oil system flush, some use kero but personally I would not use kero in a newer motor with all the seals etc Most flushes have a conditioner for the seals so as not to damage the seals.

This will help remove some of the gum and crap lying around the oil system, over the years I have had fantastic results with the Wynns but the commercial one I used to use is not avail over the counter these days.

You run for 20 or so mins, dump the oil and then proceed as per normal from there

Ok video of sound when just reaching operating temprature for a couple minates

http://tinypic.com/player.php?v=a11md5&s=3

Then video of sound. Sounds like its gone after cars been on operating temprature for 10mins and a couple of times i turned the car off and on

Why are we still going over this when the question has been answered and explained in detail.

Mad magna reckons that its not the adjustement but for some reason im thinking that it is cause ive turned the vehicle off and on a couple times will its reached operating temprature and the sound has totally disapeared so im thinking thats wat the problem is the lash adjuster or adjustment. cause everyone else that has had this problem turn there cars off and on and problem gone.? But mad magna reckons it should only do this when cold if its the adjustment

Turning the car off/on I was talking about a low pressure sound, which is similar.......however unlikely.

Tappet/lash adjuster sound was described by Madmagna in detail.

... But wait. You're completely wrong tho and it's this, this and this... :iough:.

If you just turn the car off and back on a few minutes later of course it wont do it, it has not had time to belld back

Every case will be different due to the amount of wear and also condition of the adjusters, take it to a mechanic if you are not sure as a sound clip on a forum is about as useful an xray over a mms message

if you are only warming it up for ten mins then trying the on/off procedure, the oil will still not be up to its normal temp id say. when i had my rocker of the other day, i noticed the bleed holes, and was wondering if its worth using a needle to carefully clear each hole, ie just poke it once.

Yeah, the car does not like waking up in cold mornings. Kicks up a lot of fuss on the first 5 seconds, but sweet after that.

Thumbs up! I got the Wynns engine flush from super cheap and it really did "unclog the pores". I was actually suprised how much of Gunk i physically saw at the bottom of the oil drain pan. Put HPR10 in and lash adjuster seem fine now. Feels like it breathes easier as well.

Guys, HPR5 may be a bit too thin if this issue is prevailing with you. try the HPR10 (10W-50). The extra oil weight helps prevent total drainage back into the sump.

ive herd of you are ment to clean the lash adjusters in diesel fuel, if you actually take them out to clean them
and flushing the engine in Diesel grade engine oil as it has better cleaning properties, run the car for a few mins then dump it.
but the engine flush stuff sounds like a good option, i think i might give it ago when next oil change is due, getting a little tappet noise on start up sometimes

Lol, that thread went from Kero, to Diesel fuel to Diesel motor oil.

I can't see a whole lot of benefit to running Diesel motor oil in your car for a few mins.
