Did you replace the Oil Pressure Releif Valve and its Spring ? I would fir=
st hook up a mechanical test pressure guage at the Oil Pressure Switch in t=
he block and see what readings you get. Worse case ... the Pump could be a=

etreff: [Fot] Help needed, TR250 engine rebuild oil pressure problems
Hello Triumph problem solvers.
I nearly have my TR250 ready for Triumphest/VTR after an engine rebuild.
'm trying to solve a problem now with maintaining consistent oil pressure.
hen I first ran the car after the rebuild, the 20 minutes at 2000 rpm
tart, I had Castrol 5W30 and ZDDP additive. After the engine really got up
o temperature, I had trouble with maintaining oil pressure, dropping way
own close to zero at idle. A mechanic friend of mine checked it out with
e and with the rocker cover off, we saw little flow at the rockers at idle.
had an external oiling line on my shelf so I added that and saw very good
low at start up when oil pressure was about 65 and settled down to just
nder 50 as it started to get warm, but continued to drop to the same near
ero level once it was at temperature. =20
Today I changed the oil to 20W50 Castrol with Lucas ZDDP break-in additive.
ame symptoms. I drove the car about four miles near my house and at
emperature, I was running at 20-25 psi when driving, dropping to near zero
t stop signs. When I arrived home, I removed the quite hot valve cover oil
ill cap and started the car. Very little oil was dancing around, if any,
t idle. I revved the car a bit and saw sufficient oil flowing and
plattering in there. =20
Now I don't know what to do. I have the braided oil pressure line from TSI=
.
don't think my gauge is bad with oil flow symptoms consistent with the
ressure readings. Could the oil pressure regulator be an issue? Mine is
elatively new from BPNW. I do have a second one I could swap in. The oil
ump was new with the rebuild. =20
Any advice or guidance is appreciated. =20
