[SIZE=2]patulong please. i just bought a 1996 model strada with 4d56 turbo engine. maingay po makina at high RMP. tiktiktik po ang ingay pag mataas na rpm around 2500 and above.

this are the things i did just to solve the tiktiktik sound at high rpm

1. clean nozzles tip
2. calibrated the injection pump
3. change the rocker arm to roller type
4. valve clearance adjustment (4 times na with different mechanics) tried straight 10, 12 and 14. 10 ang current na valve clearance.

note: wala naman po blowby makina. hindi rin kumakain ng langis. okay naman ang andar kung idle lang sya. kapag mataas lang rpm tsaka maingay.

ano kaya pwede pa check para ma solve ito. i tried browsing all the thread pero wala ako mahanap na related sa problema engine ko so i post this thread. also kung sino man may workshop manual ng 4d56, kindly send it to me at cadayjerry*yahoo.com[/SIZE][SIZE=2] hindi rin sya hard starting, malakas ang hatak.[/SIZE]
