This is my third year with the same problem of oil splashing out of the pipe parallel to the dipstick which is used to make an oil change.
Two years ago when launching my boat I noticed after my first run and after the winter season that oil was coming out from
the dipstick pipe splashing onto the engine cover and the engine itself when using the engine at high revs. I called in the
mechanic /s and all agreed that either a piston ring was stuck or broken or something to do with the bore. The engine still reached its
maximum revs of 3900.
Anyway took the engine out and bought new liners and pistons, oil pump, bearings, oil seals, pressure relief valve, valves, fuel pump,
breather c/w cover etc... Meanwhile took the head, crank and turbo to be checked and all were found to be OK.
basically everything has been replaced with no expense to spare including the injectors which were serviced.
Engine bench tested and worked well.
When the engine was first opened all pistons and rings were in working condition and nothing was broken or damaged.
Then in May of last year I took the boat down and on slightly increasing the speed I noticed that oil was splashing out of the pipe parallel
to the dipstick. Needless to say I heart stopped... not another Summer ruined.
Took the boat up and engine once again was dismantled. Spoke to local Volvo agent who kindly sent one of their best mechanics to inspect
the engine. Pressure test was done, crank checked including cylinder head and all was fount to be in order. Turbo and injectors were also re-
checked. On the Volvo's engineer recommendation I also replaced the some copper guides located in the c/head and seals etc..
Engine was assembled and tested and it ran well. Compression was perfect on all four cylinders.
Yesterday I took the boat down again on the mechanics recommendation I drove it for more than an hour not exceeding 1500 revs.. very slow
indeed. No oil was evident and all went well untill the moment I arrived at my berth I noticed oil bubbling out of the pipe. No not again.
How can it be that back pressure is once again being present in the sump....
I really would like to hear from someone who has passed through the same experience maybe, he may direct me to the probem.
