4k Life Expectancy

[Robert]

How many ks can you get out of a 4K before it dies.

 

Mine has nearly hit 290,000

 

a couple of welch plugs have started leaking, the front crank seal, rear main and fuel pump gasket leak a fair bit of oil, the timing chain rattles, and theres a fair bit of lifter noise.

And on long trips it uses a fair bit of oil. i.e. 1 hour of 80-100 kph = approx 2.5l of oil

 

I'm pretty sure its going to die soon, but maybe not, i hope to get another 30,000 out of it.

 

Just want to know how long the average 4K lasts?

 

Cheers Rob

Mines done round 201ks and it still runs fine just very low on compression and smokey as hell if u don't baby it lol

the engie I'm my ke11 came from a ke55 and did 100,000 in that and the went into my ke20 and was on its third time around on the clock but i don't know what the k's were on it when i got it and now its in my ke11 and the 2 and a bit years and we have never changed the oil or filter and it gets driven pretty hard

it might be time for a home service :lock_folder:

You don't say!!!

I got my car from my brother. The 3K had done around 210 000k. My brother didn't care for the car and it died. I had a recon'd 4K installed and i've been driving her for 14,000k's. (WTF I just realised i've had her for 1 (one) year as of yesterday. HAPPY BIRTHDAY LOLLA)

I've been putting top grade oil into her and changing her oil every 5 000k's.

I hope that the more i care for her the longer she will last.

I'd say anywhere from 300 to over 400 thousand kms before you need to rebuild it depending on how well the motor has been treated..

Pffft. Life expectancy? They are immortal. :lock_folder:

not too long at 8000rpm

Well Ive proven that wrong twice now....going for a third time at the moment. They might be good but a Briggs and Stratton is probably alot closter to immortal.

"They might be good but a Briggs and Stratton is probably alot closter to immortal."

 

They don't like it if you remove the governors from them :lock_folder:

 

But anything you can take to the valves with a hammerand a file and survives gets my thumbs up.

i put 230 thousand hard kays on top of what an import 4k had from japan.

 

it started to lose a bit of power and burn oil. stripped it was found to be quite good, apart from bad ring groove wear.

haha one of my mates put a 4k in his suzuki and he changes gears on the timing chain haha thats hard a very hard life and she still loves it :lock_folder: haha he just can't break it!!

mine has around 278 thousand, have only done about 6 thousand km's, it due for a service now. it dosent blow smoke or use oil, (leaks it insted) it might be down slightly on compression and is a bit rich i think. gose well though i recon it would easly make it to 350,000 might want rings and bearings by then but they last. i don't rev it over 5,000 as I'm on my dam L's and the passanger starts to yell as me, reconing I'm "over revving it" its only doing half its rev range i say..

 

on the topic of revving what can you "safely" rev these too?

 

and what has people revved theres to without "i recon it was doing, cause i don't have a tachometer"?

[Corolla_Kid]

Ive seen mine hit 8000 haha but i had no more tacho so i reckon it hit 8500 but didint sound too healthy lol.

[coln72]

Had the factory tacho pegged on 8000rpm for a while and it held together.

 

Also had a shift light on constantly for a full motorkhana and that is set to come on at 7500rpm.

[tas_ae71]

i brought a small tacho with internal shift light mine is set too come on at 5,000.... might have to set it a bit higher ;)
