Just some thoughts short of a full teardown--did you or someone plastiguage
the bearings before install?

In general, yes the TR3B has the same pressure relief as any TR3A.

Was the crankshaft cut down by a previous owner for use with undersize
bearing shells? I saw this happen in a Nuffield tractor once. Great oil
pressure at startup but diminishing quickly as the oil thinned out.

Subject: [TR] Ideas, anyone?

The first inaugural drive went pretty well, but once the engine temp came
up, the oil pressure fell like a stone - and here we are talking around
40psi at 3000rpm and almost nothing at (what was hot) idle. Adjusting the
pressure with the screw on the oil filter head did nothing.

bearings (one main and 4 rods) - all perfect.  I really didn't find

So today when I first took it out, the pressure was almost too high - around
90 at 3000 rpm.  But as soon as the engine warmed up, it again dropped to
scary levels. No leaks, no oil in water or vice versa.

Thanks for al the suggestions.  Gauge is good, have tried a new oil pump.
I think the next step is to plastigauge the bearings and check the rocker
shaft, as suggested.  Then I guess the engine will have to come out. Sigh...

Don't know for sure on TR4's but some engines source their oil pressure fro=
m the rear cam bearing, not the oil pump, mains or rod bearings. Where does=
 the TR4 source it's oil pressure? If it comes from the rear cam bearing an=
d if that clearance is excessive it could result in a very low pressure at =
idle with hot oil. Oil pumps are volumetric flow pumps not necessarily pres=
sure pumps, so you might be fine if the oil pressure gauge senses it's pres=
sure indication from the rear cam bearing. Just a thought.

Having (I think) sorted out the problem with the TR4, I took a recently-fin=
ished TR3B out for its second inaugural drive.

The first inaugural drive went pretty well, but once the engine temp came u=
p, the oil pressure fell like a stone =96 and here we are talking around 40=
psi at 3000rpm and almost nothing at (what was hot) idle. Adjusting the pre=
ssure with the screw on the oil filter head did nothing.

I checked everything over, even pulled the oil pan and checked all the bear=
ings (one main and 4 rods) =96 all perfect.  I really didn=92t find anythin=
g, and the specs on the oil pump looked good, but I ordered a new pump as w=
ell as a new spring for the Purolator oil filter head (the valve itself is =
no longer obtainable).

So today when I first took it out, the pressure was almost too high =96 aro=
und 90 at 3000 rpm.  But as soon as the engine warmed up, it again dropped =
to scary levels. No leaks, no oil in water or vice versa.

I am running out of ideas here.  Could it be a bad oil filter head?  Anythi=
ng else?

If you spin an oil pump with a long screwdriver bit on a drill, you will get
oil pressure, but no feed to the head, which makes me think the rear cam
bearing is just responsible for the latter.  But I could be wrong.

Don't know for sure on TR4's but some engines source their oil pressure from
the rear cam bearing, not the oil pump, mains or rod bearings. Where does
the TR4 source it's oil pressure? If it comes from the rear cam bearing and
if that clearance is excessive it could result in a very low pressure at
idle with hot oil. Oil pumps are volumetric flow pumps not necessarily
pressure pumps, so you might be fine if the oil pressure gauge senses it's
pressure indication from the rear cam bearing. Just a thought.

That is absolutely true for the TR2-TR6 at least. There are flats in the re=
ar cam bearing that provide the pumping action. If you install cam bearings=
 in a TR6 you have to be sure to align the hole in the bearing with the oil=
 feed hole to the head otherwise the rocker gear will have no oil feed. If =
you run the oil pump with a drill you will observe no oil getting to the he=
ad but that is not a cause for concern.

<p class=3D"MsoNormal">That is absolutely true for the TR2-TR6 at least. Th=
ere are flats in the rear cam bearing that provide the pumping action. If y=
ou install cam bearings in a TR6 you have to be sure to align the hole in t=
he bearing with the oil feed hole
 to the head otherwise the rocker gear will have no oil feed. If you run th=
e oil pump with a drill you will observe no oil getting to the head but tha=
t is not a cause for concern.<o:p></o:p></p>

<p class=3D"MsoNormal"><span style=3D"font-size:12.0pt;color:black">Don't k=
now for sure on TR4's but some engines source their oil pressure from the r=
ear cam bearing, not the oil pump, mains or rod bearings. Where does the TR=
4 source it's oil pressure? If it comes
 from the rear cam bearing and if that clearance is excessive it could resu=
lt in a very low pressure at idle with hot oil. Oil pumps are volumetric fl=
ow pumps not necessarily pressure pumps, so you might be fine if the oil pr=
essure gauge senses it's pressure
 indication from the rear cam bearing. Just a thought.&nbsp;<o:p></o:p></sp=
