So back in Feb I posted a vid of the cold start tick I was experiencing. I haven't been inside the valve cover so I don't really know what could be taking up the gap causing the tick. Fast forward to October and I ran a can of BG 44K and then some Quick Clean then changed the oil and still using M1.
The tick before the treatment was happening almost every day or every other day, always varied in duration and was routinely about 10-20 sec but this is about the longest it would go. Since the treatment I still get a cold-start tick but the intensity is reduced by about half and the other deeper noise I was hearing which sounded like a piston-slap is almost non-existent but only very faintly heard and it's muffled by the injector noise. The cold-start tick is very infrequent now, this is the first time it has gone for over a couple seconds since the treatment but it lasted longer in duration which makes me question the oil pump. I wanted to post a vid of a longer duration noise earlier but it wouldn't do it.
I drove it around for awhile and took another short vid, motor is very quiet but generally is when warm.
I imagine most people have very quiet motors but my question is, can these oil pumps lose their efficiency or overall performance at around 175K? I haven't seen these pumps yet so I don't know.
Either case, whatever my issue is has been greatly reduced but I would like to know what may be casuing it. I was thinking maybe I could get it to tick then shut it off then pull the valve cover and see if anything is a miss but that's a longshot and takes awhile.....still an option.
