First Post, I'll try to put symptoms as accurately as possible.
I've owned this Cat with Volvo
DI-30's for 4 years Port Engine
Perfect, Stbd Engine
always used some oil
200 mils over 4-5 hours.
Decided to refresh the engines before Cruising Season.
Replaced everything as usual, fuel/ oil
filters, impellers .
The troublesome engine overheated once prior to the service
(shut down immediately) ,so changed all raw water
pipes, flushed the heat exchangers, replaced both mixing elbows.
HOWEVER ON THE TRIP TO THE HAUL-OUT 6 hours running used 1.4 LITRES ON STBD ENGINE.
PLEASE HOW DO I TROUBLESHOOT THIS.
( For info, both mixing elbows were 80-85 % blocked - Stbd elbow
had a Black Greasy buildup near the header about 1/4 inch )
I tried something different with the Stbd elbow
by having a light Ceramic Coat so as to compare service
life etc, water
flow is the same both sides.
Engines 10 years old Port 2440 hrs. Stbd 2240
Thanks in Advance
