95 LT1 - oil pressure sensor
Help! Ca anyone tell me where the oil press. sensor is on a 95LT1? How easy or hard is it to access and change...My car loses oil pressure all the way to zero!, when I come to idle at intersections or stops while driving. Itis only reaching about 40psi at 3000rpm, but it will drop as I decellarate to 20psi and then to zero and check gauge light comes on. I'm also experiencing power loss when pressure drops. I am thinking eith a bad sensor or the oil pump..checked the oil(which I just changed) and it looked clean.. I used a fram filter.

To answer your question, however, the sensor is located behind the intake manifold..mostly on the drivers side. You can see pics of it on Shoebox's page... www.shbox.com |
I changed the oil pressure sensor( using shbox pics...thanks shoebox!!!) I was able to lay atop the engine, find the little ..... and replace it.. I will spare you how in blindly taking it off by hand I broke the housing off and had to use that special tool to get it completely off! So now to change the oil and get my Z on the road again.....
thanks BW...you are correct, I also have to put in a different weight oil as I found out from my mechanic and several others on this forum....thanks everyone I was recommended a 20w50 or 10w40;which would you recommend or have you heard was a better weight? |
I HIGHLY recommend a different brand of oil filter, too. A brand other than FRAM.
A few years back, I changed the oil and filter to a FRAM on my 415 CID mini-rammed L98 and when I fired the engine, I got ZERO oil pressure. I re-installed the old oil filter (AC Delco) and oil pressure MAGICALLY returned to normal. NEVER AGAIN! Jake West Point ROCKS! |
k, I've heard Mobil ! was the best to use, has any one had success with valvolines filter?

I second Jake's comments on the Fram filters. I use a Moroso racing filter and haven't an issue... If you ever have trouble sleeping and have a hankering to learn about oil.....here is a link: http://www.bobistheoilguy.com/index....tpage&Itemid=1 Everyone that is diagnosing what went wrong in their engine should take a look at the Bearing Wear Analysis section..good visuals with the descriptions |
