Lifter Noise Replace Them Or Is There A Fix?

[LatinR33]

Hey guys ive had noisy lifters for a while now starting to pee me off alittle. its only when cold for example today parked the car in the city came back drove it out to the ticket box i could hear it after like 3-5 minutes driving car nice and warm back to normal silence. Ive always used 10W40 oil should I try a 5W50 would the lower cold weight be better for cold starts?? Or should I just replace and forget??? Anyone know how much it is to replace lifter in a R33??? Thanks in advance for your responses.

Yeah I'd try a thinner oil. However going a 5W50 would be a backwards step as it would probably be thicker at startup than a 10W40 anyway (the W only refers to the viscosity of the oil at temps well below freezing).

I'd try a 5W/10W30 a go. Castrol EDGE 5W30 or Mobil 1 10W30 would be worth a shot.

yeah I will see 1-W30 ay is this safe to run not too thin?? I have a pretty stock R33 just a full exhaust I know you told me thinking synthetic oils is a wifes tale when it comes to thinking they are only for new cars and are too thin for R33 skyline turbo cars but ive heard it from a couple of peeps. Also i want a oil which gives me stable oil pressure mobil 1 supposedly gives a lower pressure I know delvac does. Anyone know how much to replace the lifters??? Also wouldnt running a thicker oil say mobil 1 5W50 quiet down lifters/tappets???

The oil is thick on startup, and thats why your lifters are noisy. The thinner it is, the less noise it'll make. You can use any synthetic in any car but the cost effectiveness is another issue. If it leaks already, there is a chance synthetics may make it worse.

Also any xW30 is perfectly fine for your R33. The factory oil was that weight anyway. I use a 5W30 with confidence. If you are judging your oil pressure by a stock gauge, its basically meaningless anyway.

I sent Mobil Lubeline an Email and they responded they recommend Mobil 1 5W50 for my car would this be an incorrect choice then for my situation???

Yes it is IMO. The solution is obvious. You need to go thinner, not thicker. What have you got to loose? Castrol 5W30 is about $50 a bottle. Cheaper than the Mobil 1 5W50... Infact I'd be willing to bet 10 points that the 5W30 will quiet down your motor...
