Hi guys, I currently have issue with the oil burn in my 2016XC90 2.0T. I reviewed few options and want to give a try with Seaform or Berryman B16 first.
all steps are straightforward except to manually turn crankshaft every 5-8 hours after pouring a bit liquid through spark plug holes. do i need to buy special tool to turn it or just a normal socket with long bar ?
also not sure where is the location trying to turn the crankshaft, is it through driving pully or can i pull belt from accessories belt?

thanks heaps

 

if you remove all the spark plugs it will make turning the crank manually a bit easier (I know that's a PITA for coil on plug engines...). Not sure of the clearances on your car but on other models I've just used a breaker bar and socket. PS I'd give Seafoam a 0% probability of fixing the problem. That treatment is intended for old engines that are already gummed up with deposits and sludge. If you have that much sludge in a 2016, you have bigger issues than oil burn. There are known issues with pistons/rings on select models where the fix is to replace both ($$$$). You can google around for related posts and discussions.

 

Thanks above, I know the cost to replace will be crazy and that’s why I will give a bit try before making decision to throw more money in. Even just slightly improved.

Back to initial question, shall I put socket onto to drive pulley or need to find flywheel first? it’s a 2.0T engine

 

drive pulley meaning the bolt in the center of the harmonic balancer on the front end of the crankshaft? that should work since that bolt is torqued down pretty hard (lol, just try removing it :-) ). if the plugs are out you may be able to rotate the engine using the accessory belt since there's no compression resistance. (but I've not tried that on a Volvo... )

 

Thanks, I’ll give a try. I’m not Not having too much knowledge to my car LOL. Just want to avoid a big bill to replace piston ring

 

As the space is very tight, not sure how to put in a wrench into and do I need to remove some parts to get more space? Not straightforward as any Japanese cars
