'10-SHO

Hi. Just joined with my (wife's) 2010 SHO. It's getting up there in age and miles (115K) and looking for insight to keep it going.

Classic phaser start up rattle. They rattle until the oil pressure builds up.One thing we're noticing that during start up is a bunch of lifters' banging (I think). It quiets down once the engine catches.
What kind of cleaning was this? You need something to get at the back of the valves to clean them. Port injection used to spray on these on the way into the cylinder and keep them clean. No fuel and detergents reach this area anymore unless you make a concerted effort to hit that area. Should be some pics of buildup floating around with a search here or even just a general google search. Good luck with the vehicle it is reaching a heavier maintenance required mileage now.Thanks for the advice. I had the fuel system and injectors cleaned out last year. Not sure what the valves look like. Hopefully the cleanout took care of any build up. One thing we're noticing that during start up is a bunch of lifters' banging (I think). It quiets down once the engine catches. Our plan is to keep the car in as good a condition as we can for another 2-1/2 - 3 years when I retire and get a vehicle I can take into the hills. So, it will be for sale then.
