Hello, this is my first post, but you guys have a GREAT site...
Wonder if any of your could help me with a problem I have been having ? - Thanks in advance.
I just got done with the rebuid on my 95 firebird 3.4 and after 200 miles it is doing the same **** thing it was doing, that caused me to rebuild the motor....
Today (and a few days ago) the "check gauges light" came on because the oil pressure was "in the red".
Before the rebuild:
1. I replaced the oil pressure sensor
2. I teed off of the oil pressure sensor with mechanical gauge, the mechanical gauge read about 2-5 lbs higher (depending upon RPM), but for the most part they were the same.
3. This problem is made worse, when the car is stuck in traffic and the temp goes up to about 230 range, before the fans kick on at 235 (this is a STUPID design having a car go from 180 to 235 when stoped - the fans should kick on MUCH sooner).
Currently when the car starts up the oil pressure reads about 60 lbs and 75 when cold out (it is about 55-60 deg F around here this time of year). After it warms up at idle it will be in the midle of the first tick mark and the read line (I am guessing around 10 Lbs).
This only apears to be a problem at idle, if you to up to about 1,000 RPM the oil pressure is about 15-20 LBS
I am using Valvaline 5W-30 and a AC Filter.
Any suggestions?
I did the rebuild myself, everything went smoothly.
When I got the engine apart I noticed the cam barings were gold in color - like they were eating into the "core" of the barring or something... - I just assumed that was the problem.
I did plastigauge the main caps before the rebuild (but not after - my mistake) it was about 0.030-0.035" - did not check the rod barrings (this is a mistake I will not make again - I should have gauged the entire engne after the build...)
Also in the rebuild i replaced:
1. Cam
2. Lifters
3. Rings
4. All barrings
5. Freze out plugs
6. Timing chanin
7. Oil pump (stock flow)
8. Gaskets
9. Etc...
Any suggestions?
