Oil Light

This is a 1960 tech engine we are talking about. You could stick some 20/50 or even 5w40 and it would still get oil pressure roughly at the same time. I am concerned about the oil pump and relief valve personally. I have even seen a cracked timing cover in these Thor engines cause similar symptoms. May even have to remove the sump and check the oring on the oil pickup too....

I would be slide traying to BOR sharp like....dont want to muck around with such a good engine nate.

Cheers

Would still be inclined to start with the simple stuff before pulling sump off , may be as simple as bad or non existant filter anti drain back , seeing as it only started after oil and filter change . if no different after oil and filter change , put a gauge on it

Yep great idea but wouldn't drive it unless it is cured

Yes, yes and yes.
Its driven from Broken Hill to here at WOT so if the pressure was a problem--
its too late now.:p
still no rattles,
The Mech offered to do a deal yesterday, he would change the oil to a 10w 40 and if the pressure light problem didnt go away,, no charge.
nice to know he's thinking:angel:
but I'll wait till after the filter change this arvo before pulling parts off.

If it was a big shop , one of the mechs could have mistakenly put their own oil in.
If you switch engine off , then restart within 10 seconds does the oil light go out quicker?

small shop, got half of one ( my supplied)container back.
yes, an instant restart makes it only just late.
Left for any length of time and its 5 secs.

found this Justin,,
though not for Thor motors I gather the same faults may occur?

Filter changed to previous version,
no change, still around 8 seconds when cold till lights out, still no rattle though.
Last check before I start dismantling is a physical oil pressure check,,
The garage where I have been doing all this has their gauge away for repairs which is why it hasnt been done.

can you still see the light go out with a gauge attached?

You out there Justin??
whats the best plan with the oil pump??

Depend on how you attach the gauge.

Put a tee in the port for the OEM light sender that way you'll see pressure to the sender and if it's low it may be a blocked port as there's still no noise symptom. If there's another place to check then check as well as if you see higher than the sender port you know the issue is in the port/sender. If it's the same you have issues.

Thanks Clubba,, there are two ports,,
the one the switch is in is really hard to get too,, when we replaced the switch the Mech just used the lower port and left the original switch in place so I can just swap the plug back and use the lower port.
anyone know what thread the oil switch is?
