I've always used the TDC method on 914-4's or Type 1's etc for over 20 years. I've done hundreds of them, gotten pretty darn good at it (I think) and confident the end product is always an improvement and that I'm not screwing anything up.
We had a local drive a month or so back with some spirited driving up a mountain pass. Ever since, my valve lash seemed to be a little noisy, so shortly after, I adjusted the lash using the TDC method (roughly 3 weeks ago). I drive my 914 daily, so valve lash isn't something I can neglect or put off. Gotta keep it spot on.
Normally when I adjust lash, I rarely touch more than one adjuster and it's usually very minimal to get it back into spec. This adjustment was similar adjusting two on the driver’s side, both exhausts. Still very minor.
Still get a little bit of intermittent lash noise, nothing big, but I can tell it's not normal. So yesterday I decided to adjust lash again even though it's only been hundreds of miles. I just don't like it when you can hear inconsitency in lash adjustment. This time I wanted to use the Cap'ns method. Figured if I screwed something up, a different method would catch it.
Well it did, one exhaust on the drivers side was a little loose.
Also, it really is nice to lay on a creeper and not have to get up....at all! Until the job is done.
Well done Krusty one, I've made the switch.
