"This pertains to the 94-98.5 engines. There are some reports of this occuring on some of the early ISB engines. "
quote from the Tech Articles Article about the KDP problem...
so am I correct in thinking I dont need to worry about this in my 91? or should I be?

 

Give yourself some peace of mind and just do the KDP-tab it and forget about it!

 

I worked with a ASE master mechanic once who told me I had no bussiness EVER touching a wrench......if this is something I dont NEED to worry about I' d rather not mess with it..

 

I have a '92 and it had moved, it didnt fall out- but it had moved.

As far as I know it should be killed one first gens.
