Oil Overfill Question

[tornik550]

I had a thread going on rennlist concerning this topic however I can't access it for some reason- sorry to those who have been reading that thread.

I have been playing around with my engine oil trying to get valve tapping to clear. I had a very noisy valve on the passenger side of the engine. Tried 0w40,5w40,half 5w40 and half 15w50. Nothing took the sound away however I can consistently make the sound go away by filling the oil to slightly above full (about 4-5m above line on dipstick). I have also ruled out that the egr valve was causing the noise (first by unhooking the valve and also because the noise comes from the passenger side of the engine).

I realize that overfilling the oil can be a big problem however I have been trying to find information on slightly over filling (4-5mm over the line). The car runs great with the current oil level and also no noise. Is it a huge problem to have the oil overfilled this much. It seems that that 4-5mm wouldn't cause frothing. I am happy now that the tapping has gone away but I would prefer to hurt the engine. Also, why would valve tapping go away when I slightly overfill the engine?

Thanks,

Steve

sorry- typo- second to last line- prefer NOT to hurt the engine. I suppose this was somewhat obvious

Hi There,

I have exactly the same problem and accidently came across the same solution - slightly overfilled - although if I leave it standing for a few days its starts with a hell of a clatter then goes really quiet annd runs as sweet as a nut. Did you get any answers to why this happens and what the "proper" solution is? I was thinking of getting rid because of the noise - are replacement lifters a big job?

Not trying to start another oil war, but perhaps you should try 15W50?

Have you received an answer to the overfilled question? I just made the same mistake. It looks like I added about 0.5 l too much. Now I'm scared to start my baby. :( And it's going to be a beautiful this weekend.

Take the oil filter off - pour out the oil in it (about 0.5 quarts) - put the oil filter back on.

Where is the oil filter?

Nevermind found it.

Oil filter housing I think he means

[lancelot092466]

Yep. Found the housing and took out 0.5 liters of oil. Level was back to normal. Thanks for all your help. I was able to take my cousin for a spin on Saturday. It was his first time in a Porsche and he had a sh*t eating grin the entire time! I think I just converted another one;)

Was there any outcome to this? I have exactly the same symptoms with the knocking engine on occasion.
