Blown Head Gasket (HG)
May I start off by saying that at this time I do not own a Cadillac but am looking for one. Don't think I introduced myself yet, I have been lurking for quite some time. I can see that there is a lot of experience on this board daily and I really need some from time to time. Now to the issue at heart. PLEASE don't chastize me for this post as I am only looking for information.
I have the opportunity to purchase a 99 DeVille. It is located about 350-400 miles from my home. It is too expensive to tow it that far. This car (according to the owner) has a blown head gasket. There is no water in the oil and no oil in the water. There is light steam coming from the tailpipe ( don't know if it is coming from one or both remember I have only seen pictures) I have read most of the threads on the forum about fixes in a bottle and I know most of you are against them. However I need to use one that will just allow me to drive the car home where I can fix it properly. That being said, I have found
Blue Devil (highly not recommended)
CRC 401232 Permanent Head Gasket & Block Repair with Nanotechnology
Is there any good that can be said for any of these products considering that I need them to work for one day for one trip?
As an aside. I have been working on cars since the early 60's and I have noticed that the 4.6l Northstar engine has displacement of 281ci. In my earlier days I rebuilt a Chevy inline 6cyl that had 230ci. When considered with the 283, 327 and 350, the 4.6 doesn't seem like it is a big as the old engines. Just saying that this suprised me as I have just noticed the comparison.......
Again, be gentle with your responses. I am a 65 year old man that just wants to work on this one at home and not 400 miles away.
Thanks for any responses received.

Re: Blown Head Gasket (HG)
Instead of re-posting info that has been already posted a thousand times in here, Seville, and Northstar Performance, you might want to use the Engines, Northstar Performance forums for research, especially the stickys at the top of the threads page - there are three that specifically address your questions.
Most CF members have a basic attitude - concerning magic potions - "Don't use them: Repair the engine properly". Using hardening sealant products runs the very real risk of permanent damage to the block and cylinder heads - thus creating a good boat anchor.
The exhaust systems on these cars is a set of phony duals - one exhaust pipe from the manifold collector to the Y under the trunk. Vapor can and might come from both pipe tips.
Engine rebuilds - been there, done that with a slew of GM 265's and 283's as well as Ford flatheads. All small engines, and, like a Northstar, all have to wind tight to develop power. Notice that the redline on a stock Northstar is 6,300 rpm. (and the engine you are looking at has the last series of flat-tappet cams - 2000 went to rollers. Any light bulbs here ??? As in: Hold out for a 2000 or later)(No, a 2000 engine will not drop into a '99)
EDIT: Unless the car's head gasket problem(s) is/are advanced terminal you can load the trunk up with coolant and nurse it 400 miles. Not fun, but doable. Even if the engine tells you to shut down due to overheat it won't hurt anything - let it cool, have a Coke, pour in coolant and continue. Long day, but doable.

Chuck, I'm with Sub. I would be very leery about putting ANY of that crap into an engine that I wanted save and last me a while.
Again, I join Sub in saying look for a 2000+.
As for that little 281, you'll be amazed the first time you plant your foot on the floor.

What's a 281 ?

He's referring to the Northstar. It's 281 cu inches.

Re: Blown Head Gasket (HG)
1 litre = 61.02 cubic inches; 4.6 L = 280.7 c.i. = Little engine that needs to wind up to make power.

I don't know much at all about engines but I thought the Northstar was kinda big, yet underpowered for being a V8
I have my eyes on other Devilles, a 97 and 98 the owners Think they have HG issues bc they get "hot" but doesn't know for sure and they jus want to dump it for $800ea.
Both are in beautiful condition, plus I would be good on some extra parts for a while... I think

The Northstar pretty small, and is very powerful for an engine designed in the '80's, and released in '93.

I do have 2codes for TCS and the traction control dash light is on, so is my ABS light, but don't know if that would mean anything
Sometimes it's all VROOOOOOM, but most of the time it's jus vroom
Other Cadillacs I've driven seem to have way more torque
Sorry, didn't mean to get off topic
