BHG Prevention
 

i recently had an engine installed in my car that has about 80k miles on it. im not showing any signs of a bhg but i dont want to have to deal with it. would going in and retorquing the head bolts prevent/delay a bhg? is it worththe effort or should i just go ahead and replace the head gasket if im going in there?

turbo or n/a ?

well it really doesn't matter it's bound to blow , if you have the means i'd replace it

from my understanding the main reason these hg blow is because they were not torqued enough from factory. ive also read that by retorqueing them to about 72-80 lb/in should prevent this. im not going so far as to say it wont ever blow a hg, but im sure it wont happen for a while as long as the hg is in good condition, put on correctly, and finally retorqued.

well it can go one of two ways

it may prevent it or it may well just crush it and cause you to blow one anyway

Been there, done that !
 

We have a saying....If it ain't broke, don't fix it.

If you are driving the car long distances regularly, and need to depend on it, you may want to replace the gasket at your convenience, rather than a major inconvience.

I've done a couple of hundred head gaskets over the years, and know 20+ people that do major engine work, and my feeling is......re-torques won't help.

And as suprragirl said, you'll probably cause it to leak.

These cars BHGs are 90% combustion gasses get blown into the cooling system, and then pressurize it, then it blows over into the bottle. So...you'll have plenty of warning that its started to go bad.

try not to drive to long when it does start to fail, because you can cause some pitting to the head and block surfaces from hot spots and cavitation at the bad spot, which is usually at the #6 cylinder area.

alright. thanks guys...and girls. i think ill leave it alone since im not currently having problem.
