Need advice mga guru

[johncoder]

Nag adjust po ako ng valve diy lang sa 13t sinunod ko yung sa 3t kasi pareho daw yung specs nun from what ive read on some forums.

.20mm intake
.33mm exhaust

tdc on 1st cyl for first set of valves then rotated 360* to adjust 2nd set

tama po ba yung specs ng valve lash ko?

done on normal operating temp according sa manual.. ang problema ngayon may detonation madalas sa 2nd gear/3rd kapag aarangkada.
nag jejerk tapos walang power tpos may parang pumuputok-putok sa passenger side and na notice ko kapag medyo mainit na makina. kapag malamig ok sya yung kaka andar mo lang

hinala ko sa unleaded kasi sa pagtipid ung mga low class lang kinakarga ko. di ko pa nasubukan na premium/high octane. pero dati unleaded naman ako walang ganun, apektado siguro ng pag-adjust


eto pa, may play po ba yung pushrod kasi inalog alog ko umaalog sya tapos may parang tunog na slamming metals need na po ba for overhaul?

tnx in advance!

If you have doubts on what you have done then better take your car to an auto shop for double checking of adjustments made. Unless you're a trained mechanic, valve lashing is better left to skilled mechanics.

err... are you sure of your specifications?
and er... are you confident that you did the valves in the correct order? i mean, it's not 1-2-3-4. 1-3-4-2 or something like that is the usual... (i'm a little embarrassed to have asked this question, but ... i have seen it happen once in a while.. naninigurado lang.)
and your last statement is confusing to me... pls try again..

[johncoder]

confident naman po mga bossing and following the manual for the valve adjustment order

first set is 1-2 for intake 5-7 for exhaust (1st piston TDC)
2nd set is 3-4 intake; 6-8 exhaust (rotated 360*)

and the engine is 20+ year old na siguro


the last one is for the pushrod "play" when you shake it.. i think the clearance is wider than specs already

[johncoder]

wala na yung detonation nag adjust lang ng dist. timing... pansin ko yung hatak and fuel consumption mas ok

it is easy to adjust ignition timing by just rotating the distributor, but you have to know exactly what your specs are, and that you are adjusting them accordingly.
read: you need a timing light. adjusting the timing without it is just an emergency procedure, to get your car to the shop that has one.

the pushrod side-to-side movement? i am confident some movement is allowed, and i am not aware if there is a table of allowable lateral tolerance...
