Hello Again:

For those of you who have not read my original posts, they are at the
bottom.

My question:

Would it be possible for me to determine whether it is the engine
block or the head cracked? (I hope I am using the right terms here for
parts of the engine...). I don't have any tools except for a few
screwdrivers, wrenches etc. for home us.

If it is not possible for me to determine it, how does a mechanic go
about identifying where the crack is?

Also, could, say, a leaky gasket be  the cause of coolant discovered
in one of the cylinders?

("Found coolant in cylinder #3" is what my mechanic said. He was not
sure whether it was the head or the block...)

I got the bad news: My mechanic says I may have to replace the engine.
He gave me an approximate cost. But he was hinting that I should get
rid of it.

I am in the San Francisco Bay Area. Any other folks had an engine (6
cylinder, I think 4.6) replaced on a F150 recently? How much did it
cost? For a truck that is 9 years old, do you think it is worth
investing more money?

Thanks!

Odds are not good of finding the problem w/o tools.

The mechanic removes the head and looks.

Yes a gasket could be leaky around cylinder #3 .

or the gasket - till you take things apart a bit you can't tell but now since
you told us the problem maybe the guyz who know the 4.6 can help, maybe
the head gasket is  a common failure on the 4.6L  .

Blocks generally do not crack unless they freeze or are severely over
heated.

Sno , why chop my message and respond to me? It's very rude and
you're not telling me anything new.  Thanks

POINT OF ORDER
Sam, You should get into the habit of placing a line break or two before and
after your comments. It is difficult to tell what you are saying sometimes
because your comments are hidden in the text of to person you reply to.

Your point that Sno replied to you instead of the OP is well taken, but
might be rooted in your habit of not separating your comments.

You're welcome. It will make it easier to keep up if the conversations do
not run together.

Guess your big line breaks make no difference either, huh?
OVERRULLED!

To keep the threads shorter and to the point. You must be insecure if
it bothers you because it is not meant to be rude at all.

Well you failed at your lame attempt at shorter threads didn't you?

Perfect. That was much easier to follow.

Thanks for taking the tip ...

You can have a crack in the head or the block, or an erroded head gasket.
The good news is, when the head it taken off, the cracked part can be easily
identified. If the head or its gasket, then repairs are pretty straight
forward, if the block then things get more complicated -- expensive.

Assuming the tool list you gave us, you are ill prepared to remedy this
problem on your own. You will require significant participation from of your
checkbook, and the assistance from your local mechanic.
