Just took the Bugeye for a 20 mile test run after restoration. =C2=A0And I =
gotta leak - a serious one. =C2=A0Front end.
1275 cc engine (rebuilt I think), 60 psi oil pressure, hums nicely, New PCV=
 valve and tube connections to the front timing cover can and the intake ma=
nifold seem tight. =C2=A0Not a bad leak when sitting, idling tuning carbs, =
but moderate driving (< 3,500 rpm - 20 miles) and my garage floor has a 1/4=
 pt. puddle.=C2=A0
A lot of the oil lays on the frame cross member before rolling onto the flo=
or. =C2=A0But the fan blades are clean, and oil isn't sprayed all over the =
front of the engine compartment. =C2=A0No leaks at the rocker cover.
I'm thinking front seal leak?, rubber seal in sump front end leak?, cracked=
 joint between oil separator can and timing cover? Faulty pcv issue (wrong =
or clogged valve cover cap)?
Is it possible that something wrong in the pcv system would cause significa=
nt oil blowing out of the front seal?
Any thoughts or guidance on tests, measurements or inspections that minimiz=
e the extent of parts removals to help diagnose? =C2=A0It's a bear to get t=
he radiator out and in.
I haven't done a compression test, yet, but plan to do one this morning.
Attached foto shows some kinks in the radiator grill - they are an artifact=
 of the panorama function in my iPhone camera - not wrinkles in the core. ;=
-)
I'd like to take the car up to the British Invasion Saturday without wrecki=
ng the engine and without filling the trunk with gallons of GTX 10W40. =C2=
=A0
Any thoughts appreciated.
Walt60 Bugeye ... so close to being done.
