Removed the rocker cover on an 80's vintage Westerbeke
to find a bit of sludge and what looks like carbon or corrosion
flakes. The engine
has suffered from absolute lack of use, having 600 total hours in 29 years and less than 100 of those in the past 10 years.
I spoke with an old guy a number of years ago who swore by the following procedure to de-sludge an old diesel
. We have replaced the tanks
, so we have good clean diesel
. The engine
itself, starts right up, does not smoke, and runs well, but does run a little rough at idle (hunts under 750 RPM):
Fill the fuel filter
with seafoam as well as adding a bottle to the crankcase, then running for 30 minutes at temp, draining and changing the oil
, repeat, then run hard for a couple of hours after the 2nd oil change
to burn the rest out. He promised it would de-carbon and de-sludge the engine every time and be far better for the engine then leaving the sludge.
I have never been a fan of additives and feel most of them are a waste of money
with the exception of fuel
stabilizers and algaecides. Any comment?
