I have a 1989 Trans Am GTA, 5.7L 350, i have had the car for almost a year and it has been buring oil the whole time. Although, lately i have been getting very little oil pressure at idel.

I was wondering what could be the cause of this? is it valve guides, Valve Stem Seals, im am not sure. I have searched aroung but havent been able to find any help.

When i start the car up it will puff out blue smoke and occ. when i drive, if i am ideling for a while the car will have trouble building oil pressure and it will die if i put in in drive or reverse, it will sometimes die just in idel.

Im looking for an answer to help solve this problum.

Thanks

 

check the gauge. i had this problem with my 88 before my motor went and then again after i put the new motor in. i put a manual gauge on and i had 60psi.

 

The normal puff of smoke at start up is just your valve seals. I changed mine when I swapped my cam.
And I agree, put a different guage on there to see what it actually reads.
Maybe do a compression test on it.
