what i learned when running my old 1s engine...
1) boss u change thinker oil can kautim one! (what happens is that when running on thinker oil, it is harder for the oil to reach the piston ring and enter the combustion chamber, but there still will be oil leaking in to it and so u will still be smoking)this cheap rm45
2) boss u fix the sparkplug adapter for sure no need to change plugs so fast( plugs still get black oil on it and take out every 2 days for cleaning) rm 60
3) boss u change electronic distributor can kautim ur hard to start(but due to oil on plug no difference)rm250
4) boss bcoz this 3 piece block u do top overhaul can kautim the engine smoke( did top overhaul twice engine overheat fast)rm1800 x 2
5) boss ur tappet must do setting onliiii( after that car overheat in 10km of driving) rm408
6) boss like this i think must do overhaul again... (i said f**K you!!! kiss my a$$) free
7)sifu 202r said i told u so many times don't waste ur money doing all this for ur engine if u really like the car change the engine (i never listen and wasted all my money now i finally listen and for the past 8 month driving with a
on my face everyday....) priceless!!! and actually cheaper than maintaining the old engine...
this is just what happen to me, up to u what u fell like doing...
