Since we first fired up the TR3A a few months back, the oil pressure has been dropping steadily. At first, it was near 50, then 20, then, at idle, nearly zero (yikes).
Despite our best efforts to remedy the problem without doing anything drastic (like pulling the oil pan off), we were unable to solve the low pressure issue.
It just had to be the oil pump.
So we ordered a new pump, new pan gasket, and pump packing, and decided to do the swap to see if that would help.
Mother Nature decided that rain was in order. For the past 3 weekends, anyway.
Finally, we had a weekend without any rain. My Father drove the TR3A over and we managed to get it up on the lift. We got the pan off, and swapped out the old oil pump for the new one. It was almost too easy. We changed the filter too, since it was near enough to the break-in period replacement anyway. Luckily, the pan was clear of any debris, despite our low oil pressure problems.
We got it off the lift, and filled with oil. It fired right up. No leaks. The oil pressure read 25 PSI, at 1250 idle. 50 PSI near 2500.
For three or four weeks we'd been wondering exactly what we could have missed that would have caused the oil pressure to be so low and to fall off like it did. What a relief to finally see 25 PSI at idle.
