I try to post this every year at "heating season" I've only seen this type of damage on SSI heats, never the stock systems.
Most everyone knows carbon monoxide is extremely dangerous. It will eventually kill but probably more dangerous to us, it can impair driving skills similar to drunk driving. A home CO detector riding with you with the heat on should be sufficient but there are other devises (as small airplanes) that are better solutions. In the past several 'teeners have posted good information on this subject. Please, try to inform everyone about this potential danger. Brad

Thanks for the post Brad.

CO poisoning is one of my (many) areas
of paranoia. Never occurred to me to keep a detector in the car becaused of the HE's. I do have a detector in our house.

For those who think they can smell the CO, it is a clear odorless gas.

Thanks Brad, for this priceless info.
From my understanding the SSI was not stock? How do you identify SSI vs stock systems ?

SSI will be metallic and not rusted(stainless steel). Stock was painted IIRC, but would likely have surface rust all over it now.

Not all stainless steel is rust proof. Different alloys can still and do rust. It took years of heat cycles to cause these to rust as they have done. I believe SSI used a different alloy in later years that are not prone to this damage. Problem is you don't know what you have. Better safe and check for leaks. All in all, SSI is a super product.

Thanks for posting these very scary pictures. It shows that even the best products do have a lifespan. General aviation sites have CO detectors available, as do RV stores.

My solution is to drive with the top off all the time!

You can get a CO detector the size of a pack of cigarettes for $20 at Home Depot. Runs on a single 9v. I installed one under my dash...out of site, but not out of mind.

This may not be a SSI brand heat exchanger. The header looks to be regular steel. IIRC all SSI units are all stainless steel.

If it can happen to a 914 or anything bolted to it, Brad Mayeur would know...

This is the one that I bought and posted last year. I like that it shows the PPM. Mine has gone off a couple of times and made it up to 20 PPM. I don't think that my exchangers are leaking, as I know that I have an exhaust leak at the heads that I need to fix.
