I have a 1996 toyota tacomah.  I pulled the cylinder head for what I thought was a blown gasket, but it turns out the head was cracked in 5 places.  It seems coolant has been getting into #2 and #3 cylinders and they stopped firing, which is when I noticed the problem.  The coolant was recently low, I found out because the heater wasn't working, but the temp guage was high, but not in the red "overheated" zone, and the light never came on.  I drained the case, and there was no sign coolant in the engine oil. 

My question is, does the cracked head itself indicate bigger problems for the engine?  Should I replace it?  Or should I just put a new head on and keep this one going.  I can't afford a new truck and I can't really afford even a used engine right now.  If a $700 head keeps me going for another year or 2, I think it would be worth it.

 Any advice?  Thanks to all.

If there was not any coolant in the oil where it could harm the crank and cam bearings,   sure replace the head, take a good look at the block and make sure it is not warped or cracked in any place.   If everything looks good a new head should be fine.

if theres no sign the block is cracked your in good shape and it sounds like you also need a temp gauge in your hose going to your block from the raiatior
