EAS preventive maintenance
 

I don't have any problem on the EAS, yet, but I want to make sure I will not have one. My 1999 RR 4.6 HSE has 60K on it now and I can see the small cracks on the fold of the belows. I intend to spend some time to get the EAS system good for another 50K miles or 10 years. After reading many post on this forum, I think I need the following: The belows, pump seal, pump mounts ( if bad or should I just change all 3 ? ) and Valve block rebuild kit. Did I miss something ?

make sure you replace the inlet filter and the exhaust filter, on the comp and valve block. also, a new dryer might not be a bad idea, most valve block failures are due to the desacent getting in the valves and making them stick

Only 60K on a '99! That's fantastic as is your forethought into keeping the EAS system up.

By valve block rebuild i'm guessing you mean an o-ring rebuild? Definitely don't skip this part. Takes a while but should really help keep the EAS in good shape.

As Roverguy indicated, buy the new dessicant for the dryer as if you don't it stops absorbing moisture and the little pellets can begin to flake and fall apart.

Regards

hi my eas system just recently cleaned and my mileage on my ride is only 7k miles, (got it from a collector) im very much interested if you have a pic of that dessicant dryer? pls post if you have thanks

no pictures, but its the black cylinder with a black hose in the top and bottom that is attached next to the air cleaner. sits verticly, and the hoses go to the eas box right behind it.

Roverguy,
Thanks for the suggestions. I can find the input filter of the pump but I am lost on the exhaust filter for the valve block. Where is it located ?

thanks ill take a look on that later :)
