Hi List,

  Sorry for the laziness of some parts of this post. I would look up the 
answers in the Bentley manual but I don't have it here at home.

  Yesterday I changed the oil on the TR6 for the first time this season. 
Since I have owned the car after a fresh oil change the car has always 
had a cold oil pressure reading of about 75lbs + and a warm pressure of 
about 50. Today I started it up after the oil change and of course 
there was no reading momentarily then instead of shooting up around 75 
the reading was closer to 25. I shut down the engine, checked the oil 
level and checked for leaks and could find none. So I drove the car 
about a mile, repeated the procedure, added a half quart of oil( about 
6 quarts of 20W 50 total) with no increase in pressure. With no other 
problems evident I figured I would drive it a little bit and see if the 
pressure came up. Tapping the oil gauge did nothing and after a bit the 
pressure did come up to a steady 25-30lbs. The car was driven for 
awhile and allowed to sit for the day. In the afternoon I drove it 
again and the initial reading was about 50lbs cold dropping to about 30 
when the engine was hot. All gauge readings other than oil were normal. 
Any ideas on cause of the drop in pressure. I think I am providing all 
necessary information. Please let me know if I am not.

  On a side note, the car performed flawlessly. The TBI system is great, 
plenty of power in 4th, even up hills. I just installed new panasports 
resulting in a loss of the persistent shimmy.(YIPPEE) Not the warmest 
day, but a very enjoyable drive, top up, back window and drivers window 
down.

  The car does have an oil leak that appears to be coming from under the 
timing cover. I have replaced the oil pan gasket twice and though the 
oil is around where the oil pan mates to the engine I don't think the 
oil pan is actually leaking. A side question would be if the leak isn't 
the oil pan then where would it likely be coming from and what is 
involved in fixing the leak.

  The car leaks very little oil while sitting but once running the car 
gets quite excited about leaving its mark.

 Thanks in advance for all the help.
