yea i noticed that i have to give it another 1-200 rpms when sitting at an idle and then it purrs. im gonna have that done tomorrow, along with my change to synthetic oil too.

 

why change to synthetic oil? all its good for is engines that get taken apart and reassembled a lot... i run regular 10w 30 or 40 and have for a long time..

 

couldnt hurt....may as well do it. 2.59 for regular high mielage oil, or 3.18 for the synthetic...it cost me 25 bucks with tax to get the oil, where before it was about 20 bucks...its worth the 5 bucks

 

synthetic oil will actualy drop your oil pressure due to its viscosity

 

i thought it was supposed to raise it

 

Not all synthetics are the same.

If you use Mobil 1 5-30 you will probably have a slight drop in oil pressure due to it's viscosity.

If you can find it, I'd reccomend the Mobil 1 0-40, I've switched my LT1 to this and now have slightly higher hot oil pressure.


Your problem is most likely related to your idle. You need a tune to get your idle right and to make sure that your mixture is correct and you aren't washing down the cylinder walls with unburnt fuel.

 

what half fast said......

and i saiid that a few posts ago

 

Cool. I was looking through it found all the lift/dur info I wanted.

 

probably not for a little while...unless i can find a set of used lt1 heads, then i will get it done a lot faster, but i havent found any for like $100 yet
