engine overhauls

[jick.cejoco]

in just a few months i have been lingering in this website, i have seen a lot of discussions of engine top and major overhauls. today's cars and engines are designed way above the cars that needed frequent visits to the crusty "mechanic" for tune up around 20000 miles, valve adjustment every six months, decarbonize combustion chambers every now and then and the list goes on. sure these "mechanics" need to earn a living, but your engine's metallurgy, design, engineering and expected endurance has far improved. there is absolutely no need to overhaul your engine for at least 15 years if you follow the maintenance schedule, use the recommended fluids and refrain from tampering the car specially if you don't have the knowledge, skills and the tools necessary to do tasks above oil changes, spark plug replacement or air filter replacement. that's why some car manufacturers use tamper resistant fasteners in fact, some cvt equipped cars do not provide you a dipstick nor a provision to add the wrong fluid.

specific year models?

Correct. With some exception on performance / sports cars though, since it will almost have no choice but to be driven hard almost all the time, plus track visits from time to time. Even if they have stronger internals than ordinary cars, followed proper maintenance, etc. I think in... let's say 20 yrs. it will have a visit w/ a mechanic for an overhaul. Just my 2 cents.

that's talking about street cars. true race cars need to be overhauled after just one run.

Yep street sportscars.

20 years?

for example the engine of a Nissan GTR will last 20 years without overhaul?

i dont think so

yes, most cars when maintained properly using the right fluids and done within prescribed service intervals. i had one 1987 mazda 323 station wagon ran to the time my daughters drove them to school. this car was older than them, i threw it away after my youngest daughter total wrecked it. i have a 1992 toyota previa, still have it. both vehicles never experienced even removal of oil pan. it all depends on how you maintained it. both only been serviced by the dealer once, at the first oil change. since then, i did all the maintenance. if you don't believe this, you are entitled to your wrong opinion

oh... i'm sorry for offending you automobile god

i'm sure you're never wrong when it comes to automobiles

i guess it's your self-appointed mission to save this poor developing country from automobile ignorance

it's sad nobody in this country is as knowledgeable as you

you're heaven sent... really

I agree, for a properly maintained engine from the start, with correct fluids replacement at recommended intervals, the engine itself will hardly need an overhaul for the life of the car. Do away with all the additives.

imho, madali lang naman imaintain ang engine ng kotse but will require conscious effort. just do d pms at correct intervals, use quality fluids and filter and your done. personally i get the latest api rating oil i can get my hands on. AFAIK, SM na rating na ata ngayon

true, malaki na improvement ng mga engines. medyo mas complex but some TLC will prevent premature and severe wear.

[Ry_Tower]

Tao nga nasisira, sasakyan pa. Isipin niyo na lang kung sino gumawa.

Kahit anong maintenance mo niyan there will come a poitn that the clearance of the piston rings will be so big it will need an overhaul. Only a fool who very very seldomly uses his car can make the vehicle last 20 years without overhaul.

Prevent premature problems but not the inevitable.

who the hell cares if modern engines can last 20 yrs without overhaul?

anybody keep their cars for 20 yrs these days?

5 yrs palang pinapalitan na

its not impossible for a car to last 20 years without overhaul but highly unlikely. if you use a car like most people (15000 - 20000 kilometers a year), wear and tear will set in (head gaskets, piston rings, etc.), even if you follow maintenance schedule. alam ko sa diesel engines, kaya more than 20 years without overhaul.

Lulutong na kasi mga rubber seals niyan kaya palit ka din talaga. PMS nga eh, preventive lang. Pero siyempre at least mas matagal gamit mo vs standard if you are extra careful.

* uls: madami pa gumagamit ng sasakyan na 20yrs old and above pero usually nga, 2nd hand na nabili. Pero meron pa rin mga 1st owner ng cars esp yung mga vintage.

i know

i'm looking at it from the 1st owner POV

since most first owners don't keep their cars beyond 5 years it doesnt matter if the engine can last 20 years

Yeah, kasi may pambili naman ng brand new, bakit ka nga naman magtitiyaga sa old car na marami na maintenance issue.

thank you . in which case, you do not need an overhaul, just resealing. i.e.: change the oil seals both from main and rear main, camshaft seal and oil pump seal, if applicable and valve cover gasket/s. sure they leak once the gaskets and the oils seals get brittle. that's just it. just reseal and desludge. no need to take your hypertension pills. hehehehehe

sir ry, actually, our family owns a number of old cars... lahat naman regular maintenance and periodic oil change lang. yung 21 yr old corolla na overhaul lang dahil napatid ang timing belt... tumalon kasi yung belt. ning binuksan, maganda pa loob at walang sludge. ang kayod lang eh dahil napatid ang valve.

would you believe we also have a 14 year old "virgin" civic? Never even had a top overhaul. tappets lang ang inadjust that requires taking off the valve cover. syempre other wear and tear parts pinalitan including timing belt change and occasional tb cleaning. every 10k oil change interval and palit oil filter every 5k. 1st owner po kami. hehe

Well, overhaul itself is a big thing. It means opening up the engine and replacing a lot of parts to bring it to specs, either oversize or undersize.
PMS is a regular maintenance of serviceable parts. I will not include cylinder head gaskets in PMS.
Age in years is not a good measurement. Mileage would be closer to reality.
