Just thought Id let you guys know.. Today I had my exhaust off and noticed all this stuff blocking my cat converter, luckily I managed to poke it all out with a screwdriver.

It looked a bit like honey comb and Im sure it wouldnt be good for exhaust flow. Just thought Id give fellow SAU members the heads up, I guess you need to check these things!

That is what the Cat Convertor is - a honeycomb that acts as the catalyst...

So you've effectively "gutted" your CAT by the sound of it, so it's not no longer a CAT - It's just a piece of pipe...

I really hope this is some kinda joke...

Whoops!

Words like, "poke", "stuff", "screwdriver", "maintenance", "pipe", "flow", "blocking" are about to...

prompt response words like...

"illegal", "rofl", "crazy", "defect", "rich", "knucklehead" as well as "whoops"

Now that I've got my breath back, can I ask you if you've been running rich? And I mean really, really rich?

A little bit of knowledge - or in the case, no knowledge - is a dangerous thing.

The honeycomb is supposed to be there - it's the catalyst that does the job of converting - hence the name "catalytic converter" - the noxious exhaust gases (NOx, SOx, etc) into more environmentally friendly compounds.

How did you think the honeycomb got there if it was not meant to be there? It doesn't exactly look like your regular carbon build up...

A bee went up through my exhaust and formed a colony, so I've been told :yes:

Tis summer, and the Metallic European Wasps are out.

Beware that your replacement metal catalytic converter doesn't arrive with the honeycomb wasp nest inside - that sort of 'blockage' is harder to remove before instal!!

dont know about maintenance as such but ive read that you dont expose the cat to unburnt fuel, leaded fuel, overheating (can melt the substrate)coolant and probably heaps of other things i cant remember, all the above can lead to a blocked or collapsed cat

Also big screwdrivers and too much poking

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
