[QUOTE="Bedok, post: 456356, member: 20746"] I did them last week at Optimum. On opening the valve cover, we found out that the valve cover seal was hard and brittle already so had to replace that. We also changed all 15 of the grommet too. First few hundred kms feels weird, it feels like I can feel small vibration on the steering everytime I accelerate. But after 100 miles the vibration lessen and now its gone completely. The seals that they taken out has harden already and a bit brittle and when we move the piston up and down we can see that one of them wasn't as flush as it shoud be. The beisan seals fits perfectly and the piston move freely with no apparent issue. The timing was out a bit maybe due to the failing vanos seal but that was easily rectified. After the run in period, the acceleration especially on lower rpm (I dont drive over 3k normally anyway) feels a bit better and the fc seems a bit better than before. I also feel that I have to use brake more now as the car doesnt slow down as abrupt as before when I let go of the gas (I am one of those prick that likes to cucuk people, hahahaha). My gearbox slight gear changing hesitation also is gone but I think thats just placebo. Thank you Herbert!:top: [/QUOTE]
