Replaced head gaskets, any problems to look for down the road?

[Harbin1]

I've got a 3.4L with 140,000 miles on the ticker. I just had the heads rebuilt and new gaskets installed because I was leaking coolant somewhere internally. Luckily it wasn't leaking into the oil because my oil never turned milky. Before I had the top end rebuilt, I had to top off my radiator everytime I drove it anywhere. I also had problems with it trying to overheat.

A few weeks before the rebuild, I had the radiator removed and rodded. The entire cooling system was also power flushed. The mechanic warned me that power flushing may worsen any leaks that were already present. I guess it did. Nonetheless, he removed a palmfull of rubber debris from the radiator and a small pile of leaves from the fins.

My car seems to be running very well now, three weeks after her little visit with the doctor. I changed my plugs/wires/o2 sensors yesterday and they perked the motor up quite a bit. [img]graemlins/banana.gif[/img]

Is there anything I should watch out for in the next few months? Like, the water pump going out, other parts failing from the leaks, or stuff like that? I would like to stay on top of anything that might try to suprise me in the future.

Any 3.4 guys with super miles like me have any advice?

The reason I ask is this, several mechanics said the same thing about my motor when I was calling around to compare prices. They all said that this block is notorious for blown head gaskets. :mad: I've been reading this board for several years now and never heard that, but when several mechanics say the same thing it makes me wonder.

Too bad I didn't hear about my motor's bad reputation a few thousand miles ago, I would have traded it in for a newer model. :rolleyes:

I got my car when it had 97k miles. I blew out the head gaskets at 103 k, thats only because i dogged the sh!t out of it. Im talking i redlined it everytime i drove it.

Im actually surprised it lasted even that long. I dogged it so bad i would only get 140 miles fro ma full tank.

They fixed the blown head gasket and now its as good as new, not i dont dogg it....as much :D
