Maybe an oil problem? After changing an oil and driving 3000miles got lifters ticking when engine is hot.
I do have 5w-60 in car, the first 5 is for cold and 60 is for hot, right?
Can I use some additives?

 

Nope...read you owners manual

Why the 5W-60?
Switch to 20-50 for summer driving, your tick will go away like magic.

 

What's wrong with 5/60?

 

I use Mobil 1 5W-50 and it works well for me. I'm in Singapore and it's basically between 25-35 degrees Centigrade all year round here.

 

Lifter rattle is caused primarily by 2 things...

1) Wrong oil viscosity
2) Worn out lifters

it is easier to change the oil then the lifters... Our cars NEW recommended oil is 20-50 for warm weather and I believe 10W-30 for cold (below 5deg C)... But I could be wrong... with age a lower viscosity oil will cause all kinds of problems... noisy lifters, rod bearing issues, seal issues...

The first number (5) is the 100deg C viscosity rating, when the oil is BRAND NEW... it goes down with age
thw W means it has been tested for colder temperature use...
the 60 means it SHOULD be the viscosity of 60 weight when cold, but if you are never seeing cold weather it doesn't matter to your car..

Not to mention in a turbo charged engine, where the oil circulates through the turbo, it is a good idea to prolong the life of the engine to shorten the oil change interval (didn't the OP say he had 3000 miles since last oil change?).. I'm willing to bet the engine is low on oil, and as the oil is getting a little long in the tooth it is thinned out beyond the 5W rating and thinning even more as it heats... (the W means it is a winter oil mix BTW... 35deg C is far from winter conditions, it is sold local to you because of the number of people who DON'T know what the number code means...)

look here http://www.upmpg.com/tech_articles/motoroil_viscosity/

Change the oil, use the viscosity called for in the owners manual, and I bet the lifters quiet right down... if not they could be dead and need to be replaced...

OR

ignore the recommendations of the Porsche engineers who made your car, and enjoy your rebuilds....

 

thicker oil will also make your oil pressure a little higher which mr. rod bearing likes alot.

 

Yes.

Wrong. 60 means the oil will flow like an SAE 60 @ 212F or 100C, not when cold. The 5W means it will flow like an SAE 5 at the cold tested temperature.

A 5W-60 oil is thinner during start up compared to a 20W-50, and the 20W-50 oil will actually be thinner at a 212F/100C operating temperature compared to a 5W-60. So again, what's wrong with 5W-60?

More importantly, other factors need to be taken into consideration when it comes to oil, and not just the weights. Zinc levels for example. But I'm sure you know all about that!


wow

 

If your lifters are making noise when the engine is warmed up, and unless you're using grandmas sewing machine oil in your engine, it will have nothing to do with what engine oil you're using. You have a problem somewhere in the top end of your engine (worn or collapsed lifter(s), possible worn cam, sticking head checkvalve/regulator, possible broken inner valve spring, incorrect valve tip heights).
Maybe, it's even injector noise?

 

+1 on a check for injector noise. Easy check.
