It doesn't matter where they were made, every 2jz was built in Japan as far as I know, and looky at this:

and so as RX7 and RX8

ya but those motors altho have limites and some faults are far superour then anything made by domestic motors. and i still think there better biult then 2g motor that could not handle some dirty oil

Its one thing to say that factory assemblies or bad oil caused failure but honestly how many stock/ never tampered with motors failed assuming proper maintence was done?

People ruin motors with laziness.

Alex takes really good care of his car (atleast from what I have seen) and he just found out that his car has walked. Just because someone gets a little lazy once a year and takes a little longer to do an oil change shouldn't make the engine fail.

i been thinking... since i do brain dead work biulding headlamps for a domestic automotive supplier, and watch quality standards get thrown out the window all the time. something you wont see at toyota in cambridge.

and this is what i came up with.

the magnus motor in thier article was fully rebiult and biult.. which to means the block was cleaned very well. plus it prolly was running really good oil and filter. i dont believe dirty clogged sqirters killed that engine. but it was just a theory.. a thoery that saved magnus a tone of money.

when the 2g motors started being biult, they started suffering from cankwalk so bad that it became an epidemic.. a stereotype.. even more so then the dreaded timing belt issues dsms been haveing for years already. but you rarely hear about it anymore. it happens but not nearly as much as it did the first 10years the 2g was around. if it was the squirters clogging up. then it wuld still be happeneing alot and here wouldnt be many of these motors left. but there is.. dirty abused 2g 7bolts running around with no signs of crank walk.

amercan manufactures are known for slacking off on a friday or hiring careless emloyees willing to work for peanuts. if there were many motors biult with less car then the standards expected,, then eventually the shotty motors will eventually all destroy them selves leaving the well biult ones still running.

maybe raising the oil pressure on the crank fixed the out of spec standards who knows but the only real way to know is if we checked the motor before it walked but we would have to know its gonna walk before it does.

I never cheated on oil changes (mobil 1 10w30) and I recall going over 5k couple times (when money was tight).
The day I got her i had slipping clutch and inconsistent engagement point. After I did clutch adjustment it got better so I never had to do anything about it again. Inconsistent engagement was always there but minor and didn't affect much of my driving. I suspect the motor was in this state since I got her
