@totaradairyunit late but thanks . is my fisrt dsm didnt know much about them back them . is a normal mitsubishi lifters tick lol

[jordanelmvp]

Yes its normal for a dsm , this my first dsm i didnt know what the noise was . But so far car is runing good and realiable must likely because car still has everything stock

[jordanelmvp]

Must be lifters , there are days that i dont get the noise like right now , i just started the engine and nothing , im using mobile 1 10 30 symthetic , engine has 144ks but seens to be ruunin strong car has everyrhing stock no mods ,i only have about 4 months with this car

i have the same problem on my car, i hope its not the conrod. Did u manage to fix it and what was it?

[bmgtz]

get some proma MBL8 and mix it with the oil as recommended......it works. I have several Mitsubishi cars with lifter noise and this stuff cures it

I haven't seen a dsm that doesn't do that. my car does it too i think its normal for most dsm's. Then after you rebuild it like full rebuild it usually goes away some how such as aftermarket pistons, rods, basically rebuild motor lol.

Lifters first guess piston slap next guess. you might be using too thick of oil. try something 1 step thinner if you want. depending on your engines health it could go away or make it worse caution when doing the test.
