If ur head gasket(s) blow

[Golbez]

Do not pass go, do not collect $200

REPLACE UR SHORTBLOCK

Or risk throwing a rod.

That is all. :(

if your headgaskets blow replace them and have the heads checked and change your oil. You don't need a new motor unless you

A) drove it a long time with it blown
B) Over heated the motor sevearly


a bad head gasket will not throw a rod, Unless A or B aplys to you.

My temp never went above 220, and when the head gasket blew there was water mixed in with my oil. I'm not sure if you've ever blown a head gasket or not, but I really don't know how you can keep driving your car after they go... I'd sure as hell like to see it. My car died and wouldn't even start after mine went.

I had a valve job done and the heads were taken to a machine shop to be refinished. It ran great, the problem was nothing was done to the bottom of the engine, just the top. With a brand new rebuilt top the bottom couldn't hold up to the compression and thats what threw the rod. Live and learn, you'll probably get to the same position that I am eventually.

Thats a myth. Unless you have a seriosly old engine the minor minor compression raise from milling a head will NOT throw a rod. My guess would be that you were leaking collant into the crank case for some time and it chewed up rod bearing, cause no oil to get too it, sezed and then blew.

Trust me, people drive with bad headgaskets all the time leaving a cloud of white smoke behind them untill they run out of coolant, the motor overheats and seizes

there was no cloud of white smoke behind me and yes my engine has 160,000 miles on it It didn't even really seize up, it just kinda died in a parking lot with antifreeze coming out of my intake going into my airbox, so I had it put in the shop to have the heads and valve job and head gaskets all rebuilt and fixed.

After that I was driving it on the highway and all the sudden it just dies. I pull over, start it back up again and thats when I start hearing the thumping. It will still drive right now, but the rod is ****ed. I don't wanna drive it very much further incase it breaks and puts a hole in my oil pan.

You can take my advice or learn the hard way when yours goes its up to you I could really care less now. I know what I saw first hand.

What I am saying is that you don't have to replace the motor when the head gasket goes. If that was the case we would have installed about 200 more motors at our shop this year insstead of just replacing the headgaskets like he do. When done correctly they are fine. If you had coolant running into your intake you had another issue come up. a head gasket will blow in 2 ways, Between 2 cylinders or between one cyl and a water outlet.

but you also say that you threw a rod, but then say that if you drive it more it's going to go through your pan indicating that you never threw it... so which is it? Did you just spin a bearing? cause that can be a totaly seperat problem when comparing it to a bad head gasket. With that much milage I would not doubt that you were having either a rod bearing or oiling problem causeing your rod failure.

What your saying is the same thiing we get everyday. Someone will come in and think that there old problem is related to their new one. IE: "you fixed my AC 3 weeks ago now my car won't start, you must have done something to it then" or "you replaced my fuel pump and now by brakes make noise" We get it all the time. You could have 2 totaly seperate issues but condem the fault to the same cause.

Telling people with a blown head to replace there motor is like telling people with a leaking pinion seal to replace their whole rear end. It's just not needed.

[Golbez]

heh well its not compeletly thrown yet, more or less the rod is cracked just waiting to break.

Someone obviously doesn't know sarcasm when they see it on an interweb forum. :rolleyes:

I'm just saying when you rebuild the top of your engine beware of the bottom as well, if my head gasket ever blows again Im having them look at the whole thing, not just on the top. I'm never making the same mistake again. I was under the impression this was a rumour myself until I saw it happen on my engine myself.

you cracked a rod? I don't think so, if your getting a knocking from lower in the motor you either like I said spun a bearing or have a bad wrist pin. When a rod cracks, it breaks. You can get some seriosly bad noise froma spun bearing or a bad wrist pin.

If your advise is to rebiuld the whole motor while your in doing head work thats fine. But telling everyone to replace there motor anytime the head gaskets fail will get a lot of people looking at you funny.

Sorry your motor went By By. But buy the milage I guess it is a good excuse to just rebiuld and have a freash motor again.

Your probably right about the bearing though, but I sure as hell won't be putting another 3800 into my car, its time for a new car.

[HBHRacing]

Meh, I like the 3.8's but for a repair standpoint that can be a bit of a pain to work on. So unless you plan on swaping a new motor in or rebiulding then your probably on the right track getting a new car.

Or a good portion of the coolant goes into the cyl and does nasty things to your valves and such...

[Golbez]

Im looking at a few WS6s heh

So if this does end up being a spun bearing or a bad wrist pin, how much damage is that and how much for the job usually? I'm probably trading it in after they find out what it is which it sounds like ur probably on the right track.

[HBHRacing]

it depends. a Spun bearing isn't bad depending on how long it was run. You can usualy get away with plishing the crank and replacing teh bearings. But if you need rods and the crank turned, your looking into some money

I would have to agree with this guy. It would be stupid to buy a new motor with a blwon head gasket. Mine went, and I fixed it myself, and have no problems right now. Engine was fine. ;)
