Subject: <e36> m3 valve tick - my experience
At 15k my 10/94 production M3 starting clacking something fierce
on cold startup. It lasted aprox 5 minutes and was lout enough
to echo off the houses of my neighborhood as I drove out in the morning.
Prior to this, I had only experienced the normal 15 second tick
on startup while the lifters pump up.
After several trips to the dealer (Camelback BMW in Phoenix),
they finally agree to keep it overnight and check it out first
thing in the morning. Now they agree there is something wrong
but they have to have the N.A. regional rep. look at it.
They replaced several defective lifters after the regional rep
heard the racket. That was at 18k. Now at 35k, it still starts quiet.
I was running Castrol 20w50 then. I'm running Mobil 1 15w50 now.
On track days, I run 1qt over and I've never had a problem with tick.
If this happened to me when the car was out of warranty, I'd just live
'95 M3 '90 K75RT '80 528i
