before the long tube install my idle pressure was at 40, after lts its at 20-30, i changed the oil while i was installing the lts, i used 10 30 mobile synthetic, i also put in a can of engine restore, could it be the engine restore? what is causing this, before lts it was fine

 

ttttttttttttt

 

i know the openin of your exhaust will make it run different cause your lettin more air in, have you got a tune yet and is that the normal oil you use?

 

normal oil mobil 1 10w 30, i just put engine restore with the oil change

 

Suppose you somehow boogered the sending unit during header installation or it went bad during the install??? Easiest thing to check first and a common prob. BTW Don't ever put that Engine restore crap in your crankcase. PURE CRAP! If you are puttin it in there you realize you already have a problem. BTW Headers have ABSOLUTELY no effect on oil pressure. Oil/exhaust systems are totally unrelated.

 

I personally would not have put that engine restore crap in the car. Years ago my brother used the stuff in an oil burning 76 camaro. It worked wonders...not sure exactly how it worked but I imagine it has cloged some of you oil passages. Good news is it didn't last very long. Try running some type of detergent through the motor and change your oil and I bet you see a rise in oil pressure.

 

im gonna change the oil, should i use seafoam, mix it in? then change oil?

 

Change the oil. JUST the oil. its all the engine needs. I f it ain't broke , don't fix it. If you want to spend extra money on lubrication, buy red line, royal purple, or valvoline synthetic. Stay away from mechanic in a bottle products.

 

Good advice^^^^^^^^^^
