Hi, I'm currently shopping around for an FD, and I was just wondering if changing the apex seals would be a good "first reliability mod?" How much would this cost? I tried search already, so have pity on me Thanks guys

 

That's basically a rebuild. You do realize that the seals are internal right?

Unless the engine is already toast, it makes no sense to do that.

 

For some reason the blue is soft on my eyes... But a change in apex seals is a rebuild. Every one just waits till it's gone or a bunch of miles are put on the engine. Your just going to pay the same.

 

Wow...But isn't it just the simple task of taking apart the engine and putting in new seals???

I was also wondering...What does the extended factory warranty cover? How much does it run for? Thanks!

 

Yea, it's that simple, but it's not that cheap. Most quality rebuilds are usually at least $3000 and up. The seals are only as good as how you treat the car. You can put the strongest seals in there, but if you lean the car out, overheat it, etc, the seals will still get damaged.

As far as extended warranties, most companies won't cover FD's anymore.

 

If it's not broke, don't fix it!

It's like changing out piston rings, you have to tear the motor apart and it's not simple or cheap.

 

Yep, like GsrSol said, if it ain't broke, why fix it???

 

The only two reasons to rebuild an engine that hasn't been blown is if the compression has gone down due to age or you're building a race-car and you need the utmost in reliability.

...and I wouldn't call doing an engine rebuild "simple".

 

I can see why changing the seals/rebuild is a good idea of the motor isn't running as well and a compression test shows that the motor isn't as healthy as 'normal'. because changing the seals before they actually blow/break can make the rebuild cheaper. b/c if the seals do break, they could just slice up the rotors or housings and make them not re-useable. And new rotors or new housings are very $$

It would make no sense to change them out due to the fact that they may be just fine. An apex seal could go at anytime. A car with 10k miles could blow out a seal if it pings.. I would agree with everyone else here. Just leave it be and spend your money on Vacum hoses or something more deserving of your hard earned dollars
