A combustion leak and an exhaust leak sound nothing alike...

If you know what you are listening for. I don't, and I know more then the average car owner, and maybe even more then the average 914 owner... You do, but you know way more then most - live and breathe the stuff.

What is the difference in sound?

I got an estimate on repairing it, and I've decided that it would be cheaper to buy a new engine and have it installed.
So thats the plan, and I guess I'll drive it when I need to until then since I'll be replacing the engine soon.

You just love to disagree with me...
To some, as Zach said, it may sound the same.
I know the difference...some may, some may not.

A compression test would reveal the truth...a leak down test would reveal more.

They are both cheap to do and I would suggest you may want to look into having one done again.

If I recall correctly, you brought your car in to have new Heat exchangers installed.
Since that time, you have a new sound.
makes me go hmmmmmmm.

the ticking/wet flag sound was there before, but I thought it was because of the heat exchangers, turns out it was in addition to them...

Not sure about what kind of engine yet, I think I may try for something a little more fun.

I wonder how much they would charge m,e to put the 3.0 from my 911 in it? (IMG:style_emoticons/default/idea.gif) Nah, I don't think I'll be doing that.

A baby and a chainsaw sound nothing alike. A combustion leak and an exhaust leak sound slightly different. (IMG:style_emoticons/default/tongue.gif)

Exhaust leaks are continual, combustion leaks are always worse under load.

Might I suggest re-torquing the head studs as well as the head nuts. You may (or may not) have a leak because the studs have worked themselves out a little.

I'll be getting a newly rebuilt 1.7
should be better than the last engine, which I drove to florida and bought, which came out a rusty car and was claimed to have been rebuilt 30,000 miles prior. (IMG:style_emoticons/default/dry.gif)

Sweet! Glad you didn't give up on it. And also glad you are leaving it air cooled (IMG:style_emoticons/default/aktion035.gif)

I would never put water in any car! (IMG:style_emoticons/default/piratenanner.gif)

The fact that we don't have any air-cooled work vans annoys me, I'm sure people wouldn't mind me pulling up in an old microbus hearse...

I think have an exhaust leak which I beleive is causing a load popping noise and I just happened to see a flash when looking through a gap in the sheet metel; I believe it's sucking cold air, I first thought I needed a carb adjustment, but I think differently now, do you think this is the correct assumption? if so, does anyone have the correct torque value for the exhaust nuts[b]. P.S> sorry if I jumped in on your thread. Regards Mike

Alright, now I am having a 1911 built!
It'll be nice to have a little more power!

I'm still driving it, it idles funny and makes some noise but it seems to be doing fine when driving.
