Hello Brian,

You know, my 99 v70 suffered and still at times continues to suffer from some lifter noise. I contacted my Indy and he also suggested BG MOA and I used that over the last several years, maybe once each year or two. Prior to the BG, it was nastly and lasted maybe 3 seconds at startup. Really got your attention.

When I first questioned the noisy lifter(s) Klaus suggested a full clean out of the crankcase with, I believe, Auto Rx. I didn't go that route, but oddly enough, I switched back from synthetic 10/30 to conventional and that along with the BG MOA treatment made a world of difference. About 10K ago, I cleaned out my pcv system and replaced components only to find they were fine. I've been religious about oil changes as we've had the car about 10 years and the lifter noise developed around 2007.

So I figure, now I've got another 100k to go before I have to clean out the pcv system again, That should get me another 10 years at the rate I'm going. Plus, knock on wood, I have no rear seal leak.

The ticking is more prevalent in the winter, but definitely less or even non-existent now with the warmer weather. In fact, most recently, the car sat for about 1 month and never a tick at startup. I really can't tell you why the synthetic does this, but I've switched back and forth a couple of times and verified the synthetic causes increased lifter noise. So even though my three old 240 tanks are using synthetic at 5K intervals, the V70 uses conventional at 3K intervals. Go figure.
