1999 Eclipse GS

99 Eclipse GS, trying to build it up and make it look clean. No I don’t have a 4G63T because 420A was cheaper.. lol

Well the motor for the GS blew… LOL so now we’re motor swapping it with another 420a. This one is low mileage it’s around 117k miles? Hopefully this one will last another 100k miles. Old one gave out @227k miles. Bad compression on the old one (red valve cover)

Low compression and piston slap are the 2 main causes of failure for old and worn 420A. You're right on par with the mileage too. Though I've seen them die at 300k with good maintenance and mostly highway miles.

If you were to thoroughly and properly build an engine, it would last for a long time and take tons of abuse. Hopefully this gets you back on the road for a while though.

And hopefully there aren't any hidden gremlins that you weren't informed of. I recently bought and installed a 48k mile engine on a Honda. Was supposed to drop in and go with a 5 year 50k warranty. First drive I found that the VVT solenoid was not functional and the valve cover gasket was leaking. Luckily they reimbursed me for those parts.

Yeah that sounds right. I have seen around 300,000 as well. Yeah, hopefully I wasn’t sold the bad engine because that’ll be shitty. Also with the GST automatic transmission that I’m already having rebuild. My pockets are drained. All that’s left is sensors to be reconnected and axles to be put back in. I’m having a dilemma though because one of the axles is kind of thread crossed I’m not sure how that happened but I have to figure that out re-thread them with the tool or kind of file it or worse comes to worse get a new axle
