so i finally got the car on ramps and checked out the exhaust system

and found what i think is the leak

the left pipe is the end of the manifold which goes over the other pipe with a small gap around the edge and its extremely sooty/black around it. So is this what could be causing the leak? i know it is coming from the front but it doesn't seem loud enough to be coming from just the manifold. Another thing i found is the muffler in the picture has two spots where it looks to have been patched but i can't find any holes in it

what is that for a car (must have missed original post). Just run it and run your hand over it front to back. You will find any leak soon enough if you cant hear it.

On another note, dont crawl around under that damn thing on ramps on grass. Find a level, hard surface to put those on, block the wheels, and put the ebrake on. Dont need another opponaut in the hospital or worse!

The sooty/black telltale sure sounds like a likely leak location. You thinking patch/repair or "upgrade opportunity"? Sorta related: Are you actually underneath a car that's on ramps on wet grass/soil? Are there at least wood block bases or something under those?

In my defense, when bierwagen fell on my head I did more damage to the car than it did to me.

hehe upgrade all the way

black powdercoated performance header mated to a new center section and rear muffler delete

Seconded. PSA note: especially now that it's hot/summer in the Northern Hemisphere, asphalt is not much better than dirt at supporting ramps or jackstands. Once plastic deformation temperatures are reached, those metal legs can sink in to driveway blacktop really quickly. And cinder blocks have a neat ability to turn to dust when loaded to/past limit in certain ways, dropping the car instantly.

Nice! I did a new performance header, resonator delete and replace with 2.5" on my Z. Really a great upgrade. I was warned it could get irritating on long highway trips, but I haven't found that to be the case, and the neighbors all like the car, so it probably isn't too loud. Would be really nice on your Alfa, I'd bet! Good luck, with the upgrades and the ramp/lift securing.

cool! as the owner of a Milano and a GTV6, I say only get murdered by Italian women, not Italian cars!

all the truth here. Seen both cases up close and personal

how hot is plastic deformation? It was only 73 here (and I was in the shade) and my jack was sinking.

Much lower than you'd think, like even high-latitude winter temps. The simple approach is just don't use jacks/jackstands on asphalt without something like a good piece of 3/4" plywood under it. I've seen them leave marks even in temperatures around freezing. And while that's not hazardous, it gives water/ice a good chance at deteriorating the driveway a lot more quickly. If I really had no choice, I'd say 40F/4C (easy to remember) around here, but only in a pinch and I still wouldn't crawl under it. Residential driveways are too often made with the cheapest, lowest spec asphalt the builder can get because it keeps their costs low and is fine for 99% of the homeowners out there. You, me, and other jalops who might use a steel-caster floor jack or jackstands are, uh, "less typical".

Yeah I put some plywood under it once it began to sink. I was just shocked it sank at that low a temp. I had no idea plastic deformed at 4c. I was thinking more like 40 c.

I know, right? Just plain weird. I saw that, unfortunately, in my parents driveway when I was like 20, doing a brake job on my truck on summer break from college. We had a concrete floor garage for my parents' cars, and I think one bay might have even been open, but it was a "I'm in a hurry, this'll be quick" kind of a thing. I felt bad about it and told my Dad. He wasn't mad, "We'll just pound it smooth with a sledge and we need to seal it anyway", but was more concerned that I know about the safety factor going forward. It was one of those classic points where my parents got so much smarter when I went to university.
