T&T: Perkins Diesel mechanic needed

[Mervyn Carr]

Thanks for that suggestion, contrary to my previous reply, I do in fact have
an oil cooler :-) Question though, with a closed cooling system would the
oil/water mix still go out the exhaust?

a
    bit of a mystery to me as to where the oil may be going.(endsnip)

  I'm certainly not a mechanic, but that seems like a  lot of oil, and if it
were burning that much I'd expect some smoke. If it was leaking that much
through a gasket or seal to the outside of the engine you would sure see in
in the bilge. One other place it can leak, and you may not see it, is
through the oil cooler. Your engine has somewhere around 60lbs of oil
pressure and if the oil cooler springs a leak, it "could" leak the oil out
to the seawater and out through the exaust. The only way you would know it
was an oil sheen in the exaust. Sure be worth checking and a lot cheaper
than an engine rebuild!
