It'* here. Now, should I just put it in and let it break in before I head swap? Or should I get the head work done real quick and swap the heads before I put it in?
Oil pressure update: After months of running 15w40 with "ok" pressure and showing no signs of getting lower... today it decides to drop to 10 psi at idle in gear. So low the CE light came on!
I didn't let it idle like that for more than a moment before giving it a little gas to bring pressure up. Next stop light, it dropped just as low.
