Yeah. Hence I took the temporary solution just now by adding lucas oil engine stop leak. I need to change the engine oil so I just thought why not try and add the stop leak and see. It might help until I get the necessary funding for top overhaul or it might not.Don't waste your money on decarb if you're planning to overhaul. It's not going to solve anything especially when it comes to the valve seals. It'll be drivable so just leave it la.
This is why I don't like engine swaps.
I also changed the stock already 'hitam-legam' air filter with Works drop-in filter. Lucas engine stop leak added with motul turbolight 10w40 all bought from Works Eng at Sunway.
