<DIV>Thanks to all for great ideas and interest.</DIV>
<DIV>Problem now resolved after removing oil pan again .... pains !</DIV>
<DIV>Issue was that the new rubber/silicon gasket did not have the small cut out
for the return oil from the relief valve.</DIV>
<DIV>This is not very obvious and even experienced AH people were not aware of
this hole in the block; the oil escapes in a gap in the gasket between the 2
flanges.</DIV>
<DIV>So this oil could not escape back into the pan and hence the pressure built
up.</DIV>
<DIV>Supplier was most apologetic as evidently this one shipped before making
this cut out ... grrr !!</DIV>
<DIV>What was also confusing was that 80 plus psi pressure only happened when
the oil was warm (20 mins running) and that is why I didn’t notice it at
first.</DIV>
<DIV>Fortunately I had taken a pix of the bad rubber one before installing and
so was able to compare it to a regular cork one that I had.</DIV>
<DIV>So for interest here are a few pix of the gaskets and hopefully won’t
happen to anyone else.</DIV>

<DIV>Does not matter the age of the gauge. (rhyme?) You need to put a
calibrated gauge inline with the oil pressure gauge. Only way to tell the
true oil pressure.</DIV>

<DIV>Just started my BJ8 after a long Winter project on OD and other
things.</DIV>
<DIV>Only engine work done was to change oil pan gasket.</DIV>
<DIV>New oil and new filter. VR1 20-50 oil.</DIV>
<DIV>When starting from cold oil pressure regulates to around 60 psi. You can
see it regulating.</DIV>
<DIV>As soon as it starts to warm up (about 10 mins running) pressure gets very
hi and follows RPM to about 100 psi at 2000 RPM. Pressure gauge is almost like a
tacho !</DIV>
<DIV>Today pulled the relief valve (not a trivial task as have oil cooler pipes
obstructing) and inspected.</DIV>
<DIV>Looks OK apart from a few scuffs on the valve; there is a small washer
behind the spring by PO.</DIV>
<DIV>Spring free length is 2.3 ins plus 0.1 for washer</DIV>
<DIV>Suspecting the filter, changed it too.</DIV>
<DIV>Oil gauge is but 12 months old.</DIV>
<DIV>Prior to this oil pressure behaved normally; and this is a recently rebuilt
engine with about 5k mi</DIV>
<DIV>At my wits end and need some ideas please.</DIV>
