Try one of the silcone based block sealants. You have to follow the directions to the T, flush all the radiator fluid out and replace with water--I took out the two block plugs to make sure I got everything out, and then add it. Just follow the directions. It is easy, messy, but done within a half day for under $20 bucks. If it works, you are golden. If you want more info, do a search and read what I did in the past. Good luck.

Water pump?

Okay, I am about to take my truck out back and kill it.

In calling around to get some head gasket/valve job estimates a mechanic finally made some sense when describing what was happening. Unfortunately, he told me that I likely had a hairline crack in my block that was expanding with the heat of long trips. He also strongly recommended against using block sealer because of the heat of where I currently and soon will live.

My question is: How likely is this the case?

How much does it run for a new engine? I would rather make the jump to Diesel, but don't know if I can afford it.

If its too much, anyone want to buy my truck?

If you are going to kill it, I recommend blowing it in place.....by far more rewarding.

I just did the jump to Diesel, it is not cheap compared to a rebuild/same engine swap. I was forced to push my engine replacement about a year early due to a head gasket failure (it was leaking so bad it was killing my starter). All told, I love my HS 2.8L and it was so worth it.
