How reliable is the 5S-FE? - Page 2

260k+ miles on my daily abused 5sfe, and still on the stock starter, fuel pump, etc.

Replacing the guides AND the seals is the only way to correctly resolve this. When replacing the guides, a valve job must be performed.

im going on 30K with my replaced valve stem seals. same old 100K guides, no valve job. no leaks yet! even if it broke tomorrow and started burning oil again, i could probably do the job 4 more times before the price evened out to a full valve job, guides and seals replacement.

im not saying its the perfect right way.. but im saying it definitely works.

my car runs fantastically well on a fully rebuilt 5sfe, great compression, great power (for a 5sfe

), no leaks, no burning.. ive spent less on the rebuild and performance parts (ported head, flywheel, bolt-ons) than most people spend on an exhaust. it'll go at least 50K more miles (good 2-3 years for me), at which point ill probably not even own the engine any more. spending more at the machine shop for me would have really been a waste.

im just saying its a good idea to spend money where money needs to be spent. a lot of people get talked into spending tons of money for things that technically provide a benefit somewhere down the line, but arent going to do anything for them.. thats how we end up with guys with 5K into their car/motor, with a 5sfe making 120whp.. while im doing the same, with the same reliability, for a fraction.

My neighbor's 92 MR2 has reached 300k miles last month with normal maintenance and dino oil changes. original engine. Mine only has 130k. I guess I have a long way to go.
