My wife started adding up receipts... let's just say new bolts are definitely out of the budget now, lol. Except for exhaust bolts, what do I have to get so they aren't breaking off in the head like the stock ones?

best to buy exhaust manifold studs, least set i bought might have been 30 bucks. they clamp the manifold on nice and tight, you'll notice how much more tq you can give them nuts vs then crap stock bolts. I got my last set at my local napa a few years back now. i brought a old stock bolt into the store with me and matched up a set just to be sure i got the right thread and pitch size.

ps: NEVER LET THE WIFE SEE THE RECEIPTS......LOL

When that happened to me it was the cam position sensor. I replaced it with one from auto zone and it was still doing it, I checked everything else possible and finally pulled an OEM one out of another known good motor and its been working since.
Coincidentally, a few months back I had an rear main seal done at a shop as I had a bad leak. Half the leak was coming from the cam position sensor, apparently i buggered up the o-ring installing when I was doing my cracked heads. They replaced mine with a Carquest part and that's when the problem showed up. They did a crank relearn at my request and we checked fuel pressures and things seemed ok. Decided on my own to just throw a few parts at it. I think I'm going to take it back and leave it with them to figure out. That or I could just order an OEM and do it myself, but my confidence is down.

Nice, I didn't even think about studs, that sounds like a much better idea.
We've been using tax return money, so there's no hiding receipts. Lol
