So... I've recently had my heat exchangers replaced becaue my old ones were old and leaky. But, it's still loud! (IMG:style_emoticons/default/confused24.gif) Head Gasket leak!

So, since I need to use this car as a daily driver, I have to know.
Is is safe to drive around with a head gasket leak?
it seems to run fine, it just sounds like a lawnmower.

Leaking anything in the combustion area is pretty much the same as a plasma cutter. Good things turn bad pretty quick.

That plasma cutter comparison was pretty good. (IMG:style_emoticons/default/biggrin.gif)

Mine sounds then same btw. It's only once it warms up does it sound terrible. Pretty sure I have a badly cracked head, along with #3 valve sunk. I drive it to the grocery store and back is about it, just to burn up the remaining gas. Kinda want to scatter the motor since it's a bus 2.0. Might be fun.

Totally drivable as long as you consider that the longer you drive it the worse the damage will be and the fact that you may end up stuck somewhere if the cylinder gets really bad.

Before I picked it up from the shop, since I picked it up on a weekend and didn't speak to the mechanic, he told me that there is a head gasket leak that is causing cylinder #3 to miss at idle but that it does fine once you get going.
That is my experience with it, I was hoping I'd be able to live with it for a little while but I guess it's gotta go back to the shop sooner than later.

Was your mechanic AA?
If so, I would trust what you were told.
If not....I would suggest a leak down test to confirm you dont have a valve seat that is crooked.

Yes it was AA, I didn't get a chance to talk with Sean when I picked the car up, so I haven't really gotten an opinion from him about the driveability.

I got it back and was still driving the work van for another couple of weeks, so I haven't really started driving it again until tis weekend, but I wil be contacting them first thing this week to se what I need to do.

Thinking about cleaning up the Bug! (IMG:style_emoticons/default/FERG.gif)
drive it until I get this fixed...

If you have a head gasket leak, I'd not fire the engine up until it was properly addressed.

If not expect to need a new cylinder head, cylinder and probably a piston.. Drive it to death has a real meaning.

I cant believe they told you it was OK to drive with a head gasket leak. That is just wrong and stupid (IMG:style_emoticons/default/blink.gif)

well now it's at the office, I'll have to drive it home at least...

I'll have a couple of days off to try to get the bug back on the road, I get the feeling that the head gasket fix might not be cheap. (IMG:style_emoticons/default/hissyfit.gif)

If you have 2.0 bus heads they will need to be tossed regardless of the damage caused by the head gaskets, unless they are relatively young AMC 2.0 bus heads.
A compression test is easy to do and will tell you if something is wrong, but only a leakdown test will tell you where the leak is.

This is what eventually happens when one continues to drive with a leaking head gasket. This was an otherwise cherry 2.0 914 head. It went on the scrap pile. What a shame!

Another angle. I could have repaired it, but once a casting has received this sort of damage it is compromised to severely. I felt it would have been good money thrown after bad and sold the customer a good core.

It should not be fine if you do indeed have a head gasket leak.
The compression test should have revealed one cylinder with lower numbers...
A leaky head gasket and a poorly fitted heat exchanger sound alot alike to most people.
