hello,

Aparently I have a posible problem with me engine ( 2,7 L, v6, 9500Km ). If I leave the Santy outside..in the morning my lifters make noise for about 2 minutes..after they go smooth..no noise at all. If I park the Santy in my garage (warmed one)..in the morning I have no noise at all.
I run Castrol Synth since 2000km on the engine.
Is this normal or I have to worry about. What I want to point is that this lifter noise is directly proportional with the outside temp.....if cold ( minus4 centigrade..noise for about 2 minutes..if between 5 - 10 centigrade...noise for about 1 minute....more than 12 centigrade..no noise .
I just want to know the normality of this problem or if is something common with this type of engine.

thanks indeed

Mario

I had a problem with the 3.3 on our SF that I swore was noisy lifters - they got noisier with time. I took it into the dealership (under warranty) and they changed the timing chain idler - no more noise.

My 2004 2.7 liter does this when it gets chilly. It was about 38ºF (3ºC) here a few nights ago and I hadn't run the Santy all day. The lifters were noisy, just as you describe, for about two minutes. Once I drove it and it warmed up, the noise stopped. It should also bear noting that I had changed my oil just a few days before and am running full-synthetic Mobil1 10W30.

synthetic oil and block heaters will help

When you changed the oil, did you use an aftermarket filter? If so, it might not have an anti-drainback valve. I'd replace it ASAP with one that does, preferably a Hyundai brand. If your engine gets damaged by an aftermarket filter that does not meet Hyundai's spec, you're outta luck with the warranty.

Beyond that, some degree of clattering on cold starts is normal, and not a cause for alarm if it goes away within a minute or two.

Having never purchased an OEM oil filter until recently, I will say I am impressed with the look and feel of the build quality of a Hyundai oil filter. I haven't weighed it, but it feels at least twice as heavy as a comparable off the shelf aftermarket filter. How this makes things better is debatable. That aside; Like Don says, I too have read of the possibilities of oil filter anti drain-back issues (on aftermarket OFs) effecting 2.7's. I'm just not following how the filter could possibly empty on these being mounted closed end down? I've read of the 'siphoning' theory, but don't get that either.

Thanks a lot to everyone !

yes, I,m using the original oil filter ( the little one) and I heard about those aftermarket filters . I think it is possible that the oil drains through that filter valve ..all the oil <column> in the engine ...or all the above filter oil quantity...can drain out through that valve back to crankcase. I was thinking that maybe I have this problem with my actual filter even if its OEM. Maybe I,ll change just the filter ..just to see the differnce ..if one
Well, thanks again for your time guys...I feel a bit reassured on this

I don't believe it is the oil or the oil filter.

In my experience it is the gasoline, especially Shell (with Ethanol).

When I switched to, say Esso, I did not experience the lifter noise any longer, even at startups during cold weather.

Interesting to see that this discussion is a virtual duplicate of one which took place in a BMW forum:

One theory which might explain NomDeGuerre's observations is that the inferior lubricating properties of ethanol-blend fuel might increase normal fuel injector noise, which is often mistaken for lifter noise. Can't say I've ever noticed this phenomenon, but who knows?

BITOG is an awesome board for anything automotive.

I,m using Shell V power all the time..he..he...didn,t know that in Canada is mixed with ethanol.
Gonna switch this evening as I have to feed the Santy...will see tomorrow morning

Mario

What viscocity range engine oil are you using? Hyundai recommends 5w20 for the 2007+ 2.7L which I see no reason NOT to run for most of us. With respect to gasoline/ethanol, if this issue is indeed hydraulic lash adjuster noise, it would have nothing to do with the gasoline being used. The only 'fluid' the HLAs see is engine oil.

In southern Ontario, a person would have a hard time finding gas without ethanol. The only fuel I know for sure that doesn't have it is Shell Hi Test tho I'm sure there are others... but I'm not paying for the premium gas. Gas prices in Ontario are going to be going up enough when the HST kicks in.

First off, you need to identify the noise a bit more closely. Not all underhood noise that sounds repetitive is caused by lifters.

If it were the lifters, the noise will be typically a faint tick-tick-tick sound. Valve actuation parts are small, and small parts make small noises. You will probably not hear it at all if the hood is closed and you standing 15ft away.

If OTOH the sound is more like a knock-knock-knock and loud enough for you to hear it sitting in the car, it is definitely not the lifters. It is probably caused by some other rotating device that is affected by the low temp. It could be a stiff belt that - once warmed up - becomes more compliant and so goes around the various pulleys smoother without making noise.

Next time, open the hood and stand right next to it and have some one else start the car. Try to see if you can hear what area the noise is coming from.

All gasoline is "up to 10% ethanol" in the States now per the Federal Gubment (thank you very much). You can't buy 100% gasoline now. Not sure how that effected you, but S. Ontario is real close to me.

Don't get me started on that crap. I was averaging 20 mpg in mixed driving before they mandated that B.S. and now I struggle to pass 18 mpg in the same conditions. Great way to reduce dependence on foreign oil; use MORE of it.

I hear ya. E10 has been around so long in the Buffalo NY area, the MPG difference is invisible to me. (IMG:style_emoticons/default/angry.gif) The majority of the stations in my area have carried nothing but E10 for ~20yrs now.

Now I use 5W30 synth oil.
The heard sound is a loud ticking specific to lifters ..in other words I feel it like a <lack of oil> between the camshaft lobe and lifter. Sincerely I didn,t hear all my life how is the injector noise ..but this noise turns more and more muffled (it changes the tonality) until it stops after 2 minutes ..
Yes I started the engine in the morning and poped the hood immediately and the noise is not so strong ( like it is sitting in the car).but it comes from the near the firewall bank of cylinders..and a bit from the front one. After two minutes the noise is stopped and the engine is super smooth .
As of the gasoline ..no result ..fueled up yesterday ..and no modification this morning ..the same noise.I was thinking of mixing a little amount of two stroke engine oil in the gas ..lets say 150 cc for the tank ...just to add a little lubricity to that ethanol gas...don,t know..i,ll see.
In my youth I use to run my engine with 100% methanol and it was a charm( modified jets in the carburetor) ...the difference was the consumption...a bit higher ..but the methylic alcohol prices were well down and the start up in the morning ..bit lasy.
Well, thanks again for your time guys

If any part of your engine is lackcing oil for as long as you described, your engine would have been toast long before you had a chance to post questions in these forums. It really is best if you don't jump to conclusions.

I would strongly recomend you DON'T put 2-stroke oil in your gas tank, unless you know exactly how that would affect your emission control equipment (cat converter, O2 sensors, etc.). Besides, the typical mix ratio for these oils is 25:1 to 50:1. Gas engines are very popular these days for RC airplane applications. Guys are flying 50cc singles to 150cc twins. Some of the competition flyers use specialized synthetic 2stroke oils that go as high as 100:1. Your putting 150cc worth of 2stroke oil in a 20gal tank is more than 500:1. I doubt your engine will feel it at all.

Billions of miles have been driven on 10% ethanol in the past 10yrs or more. Why would your engine NOT be able to cope with it?

Extreme cold temp start is admittedly one of the harshest things your engine will endure, but it is hardly detrimental. Invest in an engine block heater if you must, but stay away from the snake oil remedies.

BTW, why the 5w30? The filler cap clearly states 5w20. If you must try something else for the cold winters, 0w20 would be more the ticket, no?

From a politician's standpoint, ethanol blending is the perfect solution. It appeases those who think we're reducing dependency on foreign oil and/or saving the environment, while capturing the domestic farmers' vote. Win-win... except for the consumer of course. Such is the nature of all politically-imposed "solutions".
