Circa 1974
Westerbeke W80. It's based on the Leyland 4-98 tractor
engine. The issue started out as
engine dying after about 5 minutes of running. it did this twice to me. I took this to mean clogged
fuel filter, so I replaced the
Racor and the main engine filter. After that, the engine wouldn't start at all.
We found
coolant in the intake manifold, with no obvious source, no
coolant in the
oil. I took the
head off and had it magnafluxed, no cracks. No cracks in the
gasket either but replaced it anyway. I had the
exhaust manifold / coolant tank repaired as there was some
corrosion that might haven causing coolant to leak into the
exhaust (possible source of coolant in the intake?). I also had the injectors rebuilt while everything was out.
I've bled the system and get
fuel at all the bleeding points (I have an
electric fuel pump I can turn on manually), and I see drips at the injector unions when turning the engine over. I know this is a point of debate, but when I spray (very little) starting fluid it will kick over a little.
I'm at a loss here, did I screw something up when I replaced the filters? What should I check next?
