As some of you have known, I was the guy who posted a question about my noisy valvetrain when I used Castrol Edge with titanium 0W-40 a while back. If you guys read that thread, you heard that I was going to open the valve cover and do a cleanliness inspection. I think with the amount of high res pics I am gonna post, I think this deserves its own thread. So have a look at this pics. The valve cover has never been opened since september 2004. Engine is a 4 cylinder inline Mitsubishi 4G13 that has travelled 370,000 kms on dino from 1992 to August 2004, and was in bad shape then. I did a complete overhaul in August 2004 and got back the engine a month later and has been on synthetics all the way except was fed magnatec semi twice only early in its overhauled life. I wasn't happy with the magnatecs performance and switch to synthethic.
List of oils used in order of frequency. Car has clocked 120,000kms since September 2004.
1. Shell Helix Ultra 5W-40 Syn (about 8 OCI)
2. Castrol magnatec 10W-40 semi syn (2 OCI)
4. Duckhams QS 5W-40 Syn (2 OCI)
3. BHP Syngard 8000 Syn (1 OCI)
4. Mobil 1 5W-50 Syn (1 OCI)
5. Castol Edge OW-40 Syn Currently using at 700kms only










Let me know your opinions, but it looks really clean to me, cleaner than my pals car with the same engine but he only uses dino 20W-50.

Thanks Mr Senna smile Yes it has been an expensive experiment on my car but it looks like it has totally paid off. In my country there are a lot of uninformed people who still thinks oil works the same way 25 years ago. I still hear a lot of people saying that 5W-XX oil is too thin for tropical climate and only can be used in expensive cars and not a low end econobox like my car. My mother in laws car , a 3cyl Daihatsu from 2003 had a complete seals failure in the engine. And as I was getting it fixed ,I was talking to the mechanic about the inside of the valve cover being totally covered in deposits and I said it was because of the mineral oil used. He insisted all oils are the same and that deposit layer is completely normal. A lot of mechanics in Malaysia simply can't read English and learnt the trade as apprentice. To them oil is oil. I did not adjust the valve clearances and will be giving him to do it. Would love to see the look on his face when he sees the valves and the cover !

Looks good. How long are the OCIs? How many miles since the rebuild?

OCI have been anywhere from 7000km to 9500km. I change somewhat early because I live in a very hot climate . The engine has run 120,000 km since rebuild.
