Hey bro! I'm new here and I hope matulungan ninyo ako sa problema ko sa kotse, It's 97 lancer EL 1300 cc. noong hindi pa na semi overhaul yon ang ganda ng hatak kahit 1300 lang yon. kahit sa matarik na ramp kayang kaya. Pero simula nung na semi-overhaul dahil accidentally natuyuan ng langis, Pinalitan ng connecting rod bearing, main bearing, oil bearing, water pump at timing belt. I think ok naman ang pagkagawa pero napansin ko huminang humatak pag nag start up ako ng makina. kailangan painitin ko muna ng mga 5 to 10 minutes sa umaga para malakas ang hatak. kasi sa basement level ang parking ko kaya kailangan malakas makina para makaahon sa ramp. pero pag nag init na makina ok na takbo nya.
Sa province kc ako nasiraan noon kaya sa province din ako nag pa semi-overhaul malayo dito sa manila. kaya hindi practical na balik balikan ko yung gumawa para magtanong kung ano pweding gawin sa kotse ko. sana may makatulong sakin dito sa forum kung ano dapat kong ipa check / ipagawa sa kotse ko. thanks.

IMHO hindi talaga 100% na magiging the same yung feeling ng kotse mo kapag pinalitan nila yung some of the internals kahit pa OEM parts yung nilagay nila... And also, kelangan mo naman talaga i-heat up ang kotse before ka tumakbo, otherwise you're shortening the car's life little by little...

Thanks dudes, siguro nga, pero dati kasi noong di pa na semi overhaul yon. instantly kahit hindi ko painit makina, okey ang hatak. i dont know if there's a problem or not.

you mean natuyuan ng oil and yet semi overhaul (as per your term) lang which i think should be a major overhaul. at any rate it could be a cam timing issue

baka masikip pa adjustments ng valves niyan para lumapat ang ginawa ng mechanic. try to re-adjust yun valves mo sa specs. pa compression test mo din baka yun piston rings mo may tama na rin kasi pag mainit nag expand na yun rings kaya ok na siya humatak. kung matarik talaga you have to warm up the engine or rev it up a bit. sa baguio nga from a starting start sa house ng friend ko hirap umakyat yun Gen1 ko dati. Dapat painit muna.

It was not properly overhauled.IMO.

Same opinion as afrasay, the engine might be too tight... give it a few hundred kilometers to loosen up, but do the compression test, too.
It's really hard to get things done with an overhaul, and the less you change, the more chances of a problem cropping up in the future.

hmmmmnn... interesting fact or myth(?)... i dont think mythbuster will agree with this... and if i do belive this, motortv should advise me not to watch them again... OT...
once its overhauled, it MAY never performed the same way again... means.. badly done...

hmmmmnn... interesting fact or myth(?)... i dont think mythbuster will agree with this... and if i do belive this, motortv should advise me not to watch them again... OT... In this case he has to warm it up for about 1-2 minutes before revving it to climb out of that underground garage. I didn't say to warm it up while idling for more than 5 minutes or so <-- do not do that. During the mornings, if you take it to drive right after you turn the car on, the oil won't provide any protection, which happens to be one of it's purposes. The oil has to raise its temp from FULL cold to get to the vital components of the engine. Do not let it see higher than ~3.5k rpm unless the oil pressure goes down from ~30 psi and the oil temp reaches 160-180 deg, which will probably take up to 15 minutes of steady driving...

parang signs na may langis ang spark plugs.. diba mausok?
baka valve steam seals or something else..

or..
mga cheapi-pays ang pinalit na pyesa sa overhaul mo last time.. tsk!

just got mine OHd a month ago..during the first few days, medyo bitin talaga kasi nga di pwede i-upak..may mga internal parts pa na kailangan lumapat...but after a few weeks, ok na batak nya..di man kagaya ng brand new but additional hp is very noticeable...ilang days na ba after ma top overhaul? (semi OH ba, top OH un)
di nga kaya palpak ang pagkaka-OH ng engine mo? pa-tsek mo na din kaya? saan mo ba pinagawa yan? baka pwede mo ibalik dun sa probinsya kung saan mo pinagawa for the last time...pag ndi ka pa rin satisfied, dalhin mo na sa malapit na mechanic sa inyo para ma-double check...
regarding sa warm-up ng engine, ilang minutes ba talaga ang warming up? read from the other forums na 1-2 minutes lang daw ang warm up then pwede na tumakbo ang auto..but ndi pa rin pwede upak...mga 15-30 mins slow driving daw muna dapat...

Thanks for the advise mga bro, I dont think na cheap yung pinalit sa mga piyesa sa pag overhaul coz co-mechanic ng pinsan ko yung nag overhaul. it's so happened na nasa probins yung gumawa/shop. kaya wala akong time to go back there. and also i like to hear other opinion.
Paano ba ginagawa ang compression test, saan shop ba ako pweding magpa compression test? bubuksan ba ulit ang engine ng kotse? please advise.
Thanks to all.

Reply to Buraot,
Actually kaya ko nasabi na semi overhaul lang yon dahil hindi ibinaba yung engine, dinukot lang daw sa ilalaim. dahil minor defects lang daw ang nangyari.
But i thing i'd like to confirm sa mga malaki na experience sa ganito, kapag ba na overhaul ang engine ano mga usual effect?
Sa kotse ko pinalitan ng mechanic yung connecting rod bearing, main bearing, oil bearing, water pump, & timing belt.

malamang kumatok yan engine mo ng mawalang ng langis... teka bakit ng ba nawalang ng langis? ang kumakatok dito ay yun connecting rod bearings. your mechanic should have check for piston play, not an accurate way pero it would give you an overall idea what the damage could be.
si autotechnika and perhaps si speedyfix and other diesel shops listed here do compression test. madali lang ito. they just remove your sparkplugs (for gasoline engine) or injectors (for diesel) and the put a plug with a hore and meter at the end in place of it. then they crank the engine without letting it start. the reading in the meter indicates the pressure that each of your cyclinders give.
Supposively after an overall your engine would perform back to its original performance when new. It could perform a tad bit better due to reboring and oversized pistons. If rings were change you need to break it in to settle and "soften" up the rings. A week or two driving below 60 kph and not reving it hard would be more than enough for a break-in. After that drain/flush the oil
, replaced the oil filter too, have the valves/timing adjust.
Do not race a cold engine let alone make it climb steep roads 30-40 degrees. As what one poster said, oil has to circulate in order to protect the engine.
BTW, how long since the engine was semi overhauled?

bro anong kulay ng usok mo? sori ha kung misleading itong tanong ko pero ito ang isa sa pinakaimportanteng tinitignan after ng top overhaul or semi-overhaul. any unwanted vibration after nung overhaul? how about engine noise?

regarding sa warm-up ng engine, ilang minutes ba talaga ang warming up? read from the other forums na 1-2 minutes lang daw ang warm up then pwede na tumakbo ang auto..but ndi pa rin pwede upak...mga 15-30 mins slow driving daw muna dapat... In the morning, I turn the car on and wait up to 1 minute or so before I take off (not sure about the exact tme), but keep it below 3k for the first 10-15 minutes of driving. I use 10W40. The water gauge goes to the middle before your thermostat even opens. And when the water is already at warm or at the right temp, you'll notice that the oil isn't warmed up just yet and hasn't reached its normal operating temp. It takes 10-15 minutes for the oil to get warmed up (in most cases, also depending on what oil you use and the weather)... Until then, you're not supposed to push on the car any further ~Higher revs on cold engine = lots of wear...
-never run below 1500 rpm to avoid carbon buildup and overstressing the rods
-wait until the engine is warm before going above 3k rpm
-don't sit at idle for a long time because it's hard on the cats and you get incomplete combustion with a cooler engine

does that mean, that during normal driving, the rpm should be at least 1.5k? at what rpm should i shift gear in that case? I usually shift at around 2.5k-3k...
regarding the last suggestion, i sometimes leave the car during cold start to 3-5 minutes idle since i'm still preparing the things i need to bring along when i drive..sometimes,more than 5 minutes..is that bad for the engine to sit at idle? what will be the effect of leaving the engine idle for long?
regarding the loose compression test, some gas stations do compression test...pa compression test mo na para malaman mo kung bakit mahina pa ang hatak...mausok pa rin ba?

does that mean, that during normal driving, the rpm should be at least 1.5k? at what rpm should i shift gear in that case? I usually shift at around 2.5k-3k... yups that's what it says, never go below 1500 rpm, and never let it see beyond 3k rpm, that's just another way of saying "stay within 1.5 - 3k rpm... I shift at 3k rpm, then the needle goes down to 2k... regarding the last suggestion, i sometimes leave the car during cold start to 3-5 minutes idle since i'm still preparing the things i need to bring along when i drive..sometimes,more than 5 minutes..is that bad for the engine to sit at idle? what will be the effect of leaving the engine idle for long? That is more of an emmision issue, but I don't know if it really does some damage to the engine, some say it does some say it does not... When you start a car, more fuel is introduced into the engine. It requires some throttle input to switch over from a rich warm up running condition to a normal running condition. During the warm up period, unburnt fuel could make its way to the cat/s which haven't reached operating temperature and cause them to clog and start over heating over time.
Warming up at idle takes longer for the cats to heat up
