CamPro 1.6 IAFM loud tappet after years of thinner viscosity oil between 5w40 to 10w40.
After consultation with Sid from RPG, he said it wasn't my IAFM (thankfully, its been 4 years++ now), but my lifters are loud, use thicker oil instead.
Immediately, 20W50 sprung to my mind because it is what Proton recommends eventhough Proton SC is not using that weight.
SO fuck it, contacted Fstr to hook it up, got myself some 20W50 of 76 Lubricants. Changed it real quick at home because the noise makes me crazy especially when I Uber now.
First drive didn't make any difference but after sitting for a night, it quite down. Even better after the 2nd night.
I wasn't prepared to fork out RM70 just for one lifter. We have 16 of those.
Timing belt soon... RM330...Another set of ATR Sport this weekend RM185.
