QUOTE(Perry Kiehl @ Jun 7 2018, 03:01 PM)  FWIW the "old school engine flush" is 1 part kerosene or diesel to 3 parts new oil, run until it gets warm to the touch and drain. Refill with new oil, change oil in 500 miles or 8 hours. This is what a Navy mechanic told me anyway. Actually you are correct,diesel is kinda ok ,reminds me when I ran a smaller stern trawler my first job as chief engineer had 2 aux engines to run domestic power and winches,we swapped load every 200 hrs but they had a habit of puking injectors before service time (2K hrs) and the oil dipstick would float up and down in the tube,used to be a mad rush to change duty (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) . We used to do overhaul them every 45K hours ,the bottom end bearing were always within service hours but replaced anyway. Anyway rant over . |

Just drain the oil and split open the filter. If theres something wrong it wont fix itself and you'll just worry untill you know, an idientified problem is a problem that can be fixed, untill then its just speculation.

Goodness I need to read more posts! My 3.6 did the same thing some years back driving home from a long hard track day, but without that much drama. The valve-noise lasted for about 10 seconds several times. It wasn't all of the valves though, perhaps two of them and my oil pressure was fine.
A few folks thought it was likely the hydraulic valve adjusters and I found that a plausible thing. Changed the oil, inspected the filter (no metal) and it never returned. I guess it's a good thing Porsche had two oil filters for that engine. |
