My mechanic told me to leave it connected cus i am just building a Vac leak,so i have but i had it disconnected and i had full boost =( i miss burning tire, but the weird thing is i could be at a roll maybe 15ish and it wouldn't break loose but i've read other members have a nearly stock car and at 20ish they still break loose

As for seafoam: i used it in the last engine and the day i poored it into the oil i did half break booster cable,half crank case * like i've always done* and my engine went later that day, so im sorta scared to try it again on this engine
=( even though i LOVED the stuff it worked really good, and really did the trick on cleaning the engine out, and this engien was kept in a barn for the last few months so i can't amagine what kinda crap is built up in it ....

Fuel filter was my next thing, i still have a brand new one from my Bonneville that i recently sold, is it the same part number?

I have noticed my mpg is just horrible like 12ish around town and MAYBE if im lucky 20 on the hw... Fuelfilter might do the trick =)

What would be a good daily driving oil ? I normally use Mobile 1 syn, but i have been considering either going back to using Valv synthetic, or maybe RP?

Input is greatly appreciated!!
