My son has a 2000 Mitsubishi Eclipse 3.0 v6 About 3 months ago ,he replaced the intake gasket cause there was a bolt missing on intake and he thought it had a broken bolt in it, but it wasn't, and after a month it started bogging down and idling rough .Thinking he might have did something wrong , I replaced it again, and also the sparkplugs but still didn't fix it. so I Took off cap and rotor and plastic cover behind rotor and there was oil in there ,so I cleaned it out good and replaced cap and rotor, and it ran great for about two weeks and started doing it again ,so today I cleaned it out again and it runs great so i'm guessing its the oil inside the distributor making it lose contact some how. Has any one had this problem before ? Is there an o ring inside of it that can be replace? I know there's one on the out side of distributor housing were it goes into the head. any advise would be great. thanks

 

sounds like the bushings in the housing are worn out time for a rebuilt dist

 

take rocker cover off, put at tdc, take hold down/adjust nut off dizzy, pull dizzy out, check for play in drive pinion, if no, replace oring.

 

Thank you for the advice I haven't messed with it yet but will let ya'll know what happens when I mess with it.
