I was told 50k was expected lifter life ... in my case the bad roller got bound up in a position that allowed the engine to run quiet and with no problems ... the hammering starting once the roller spun to a bad position ... I have no idea how long the roller was going bad ...

had to clean everything out and replaced cam and cam bearing and seals ... actually did a complete engine rebuild while doing it ... that was two years ago, all good since then ... but I will start checking them around 30k

 

 

You are right ... had a senior moment, but at 66 I'm allowed ... should replace instead of just check ...

of all the things I've lost, I miss my mind the most ...

 

Just wait until you get to 70........... the drooling starts.

 

Oh Yea ... something to look forward to

 

i had over 130,000 on mine and replaced them when i did rebuild...they looked fine tho...i run straight 50 wt
