Don't replace a Blown Head Gasket without a Chiltons!

I should know.  I tried it, and failed!  My friend, Dan has an 84 Mazda b2000 pickup with a small 4 cylinder engine in it.  It took about 3 days to get everything apart(rusted and frozen bolts), and took a little over a day to get it back together.  While we were putting it back together, the crankshaft turned just a little bit while the timing chain was off(we didn't have the timing cover off).  We got it to what we thought was TDC, and started putting it back together when we discovered that the chain was too tight!  The tensioner was not designed to loosen unless you do it yourself.  We ended up having to take off a bunch of other stuff.   To make a longer story short, when we finally got it back together, and tried to start it, it was spitting exhaust out the carburetor, and trying to suck air into the exhaust pipe!  Oops!  Well, maybe next time.   I'm going to do Bro. Pridgen's brakes next week, then maybe try to take it back apart and get it right.  The moral of the story. . . If you don't know what you are doing with a vehicle, get a Chiltons or a Haynes!
