Subject: Valve train noise - Part Deux

Date: 	Fri, 1 Aug 1997 15:21:27 +0000





     I've started thinking maybe a deflated lifter.  Anybody have any 

     relevant experience?  That seems like a significantly easier 

     replacement job than valve springs.  Can they be "re-inflated"?  I'm 

     going to change the oil this weekend with Mobil1 and cross my fingers.

     

     Thanks

     My 90, w/90k miles, started making a very scary ticking noise 

     yesterday.  It is engine speed dependent, seems to be coming from 

     under the cam cover, and is loud enough to be heard in the cockpit.  

     It sounds like my old 302 Mustang when a rocker arm or lifter tappet 

     went bad.  The oil has been changed every 3-4k miles with Mobil dino 

     and a clean filter.  I know there are many people with twice the miles 

     I have, so am I just unlucky?  I'm going to buy a new cam cover gasket 

     today and pull the cover.  Does anyone have any experience doing valve 

     work on these engines?  Hopefully it is just a weak spring or 

     something of that sort.  Otherwise I think I'll be putting a 13b 

     rotary.....

     

     

     Thanks
