Sorry to bring this back from the summer but I have been using 10w40 Valvoline HM in it and was running great. Now with the weather getting colder it ticks and almost knocks until fully warmed up. My question is this...would 5w40 or 0w40 be best considering I had low oil pressure issues in the...

Yeah it dropped to like 10 yesterday but jumped all over the place and back up to 30 driving and 15/20 again at a light. I just now changed the oil to 10w40 so we'll see what happens. As for location of the gauge...I have heard there is one on the block or head on driver side...I noticed the...

Thanks everyone you guys are AWESOME! I am going to take a look at the sender and pull it this weekend, change the oil, filter and probably the sender also. I was thinking that if I put a manual pressure gauge it may not run/run right due to all the fuel [censored]...any links to ways to get...

Thanks everyone so far. Just had a couple other questions that I was wondering hoping you could answer that I asked above. Also...is 25-35/40 okay for while driving/accelerating? I just hate that the darn thing bounces all over and that it had that stupid warning light pop on and drop so low...

In the past on some of my cars that i used to race I used M1 all the time...with what this engine has been through any thoughts on which HM oil would be good? Just a decent Valvoline, Castrol or Mobil? Not sure if I need to do full synthetic since it has already probably never been used before...

It burned about 1 quart in about 2800 miles. No real ticks knocks or anything that I can hear. It actually runs real smooth which is why I am so confused. The light came on when the pressure was REAL low but like I said it was after sitting idling in 90+ degree heat in a parking lot with the a/c...

Okay so I just got a 1996 Suburban that I didn't know much about the history of, just that it had a blown intake gasket for some time and the previous owners just kept filling with water. I have rebuilt the trans, transfer case, fixed the intake manifold gaskets, water pump, and full major...
