sir oo nga masyado malaki o mataas na ang 2k rpm para sa 1 2 3 tsk hagulgol na ang makina mo nyan baka mapwersa pa ang ka overhauled mong engine? pag ba hindi nya na reach ang 2k + rpm hindi ba sya nag shi-shift?
btw this is your 2nd hand car ba?

April 15th, 2009 09:14 PM #12oo sir, kahit nung hindi pa ako nag papa overhaul ay ganun na ang trany ko, pag nasa 90kph nga ang takbo ko nag 3k to 3.8k rpm na cya eh, pero talagang mabigat ang takbo nya kumpara sa dati bago ito ma overhaul, kasi nproblem ko dito dati usok lang en hindi nag kakagat ang shift ngayon mabigat na takbo,
pero mga sir, lahat ba talaga ng inooverhaul ay mabigat takbo sa umpisa? or habang nasa break in period pa cya? kasi talagang lose power ang paki ramdam ko dito, kasi pag tinappakan ko gas pedal matagal nya iangat ang RPM, diba dapat ag nag rerevolution ka ay parang magagalit ang makina en yung RPM nya ay alis kagad sa 0, sakin makupad cyang umangat kahit biglang tapak ka

if i were you i would take it to mitsubishi na, or mang kontrata ka ng technician sa casa to work on your car some weekend for the final adjustments post overhaul. i'm guessing mali or tukod ang timing nyan kaya walang power. have the timing checked, the proper timing belt tension, and throttle body intake cleaning. change your sparkplugs too.
bihira ako makakita ng shady tree mechanics na bihasa sa EFI engines like yours. galant MPI yan di ba? usually specialties ng mga yan eh mga tamaraw fx diesels at mga old school carburated cars. mga engine components kasi nun salpak lang ng salpak sa pagkabit (cause they're simpler than the precision fuel injected generation engines).
you should not entrust your relatively high tech engine to a mechanic with onlly a bag full of tools and a promise na "kaya" nya yan.
you should ask around sa forums before going into major repairs. we could have suggested you first check your valve seals. 300 lang isa nito x 4, = 1,200 lang plus labor. leaking valve seals cause the same problems you mentioned (white smoke, oil sa tailpipe). white smoke is oil, blue black is gas.
that said, i'm also pretty sure your transmission is busted. get a surplus, because an overhaul will cost just about the same (maybe more) as a fresh surplus from japan that will give you another 5 years of trouble free operation. or maybe hindi lang maayos ang adjustment sa throttle cable mo (pa check mo mura lang yan).
worst case scenario, the new sleeves and piston rings did not seat properly. pagka salpak nyan dapat hindi sya hirap tumakbo gaya ng sabi mo. in fact, the engine should run better and better every day you use it. pero since hindi mo sinabay ang repair/replace ng worn a/t mo, how will we/you know what's causing the bad power delivery? engine makes the power, tranny transmits to the wheels, wheels to the ground. may problema sa isa dito and you will have problems.
now kung na check na lahat lahat, at pangit pa rin ang takbo after using for a month or two, dapat na talaga mabuksan ulit at masilip kung maayos yung kain ng ring at bagong sleeve.
hope this helps.

April 16th, 2009 12:52 AM #17* voltscastillo sir thank you sa time en payo mo, kasi sabi ng mechanic eh ganyan daw talaga lahat ng inooverhaul, kasi naglalapat pa ang ring sa sleeve eh, hmmm totoo ba yun sir? kung ring lang daw pinalitan at hindi nag pa sleeve ay maayos daw kagad yan, pero since na pina sleeve ay nag lalapat pa daw yun,
*yap - sir thank you so much sa time mo, cge kung kaya tumakbo ng auto ko pa punta dyan try ko, pero kasi kahit malapit lang ay hirap na, tapos pag na trapik pa ay mag ooverheat cya

np. i hope you get that all sorted out.
electronic fuel injected (efi) engines like yours were built to high precision specs. hindi na sya gaya nung mga lumang 3k or saturn na makina nung 1979 - yung clearances sa loob are not as loose as those found in old engines. so pag inayos, dapat precise din ang kabit, at alagaan ang computer box lagi pag mag diagnose.
i'm not saying that the efi engines can't be serviced by shops other than the casa ha... i just mean that servicing them requires experience and more technical skill.
if the rings and sleeves did not seat properly, you will have to re-do the overhaul.
if the bad power doesn't resolve, something's wrong in there. that said, i have yet to see an overhauled engine with bad performance like yours resolve sponteneously. it's not like it's going to heal itself you know.
at first start after putting it all back together, the engine should make good power even if the rings haven't seated properly. from there, 2 possible outcomes: rings wont seal with liners = wasak. rings seal properly, engine starts making more power and starts getting quieter.
my top 3 guesses:
1. transmission.
2. timing
3. at 1st start the mechanic failed to set the fuel/air calibration. you're running rich, gasoline is washing down the sleeves removing the precious lubricating oil preventing the rings from seating properly, forever.
crucial ang 1st 5 hours ng initial start up. if you don't resolve the issues above within the time frame, the engine will never break in properly.
but, you do have hope. have items 1 and 2 checked muna.
