I’ve been working on the 8.1’s I picked up about a month ago. In the process, I have been delaying the inevitable, the cylinder walls need a clean up so I’m going to do a more invasive teardown. It’s cold out and they’re sitting in my garage so I would be stupid not to invest the time now. That decision has already paid off because....
I found water/coolant in two of the exhaust ports when I removed the exhaust manifolds last night. This was the engine that made note of that in the report from Blackstone. This one also had both exhaust manifolds replaced which I thought was odd since it’s a full FWC engine. I already replaced the risers a few weeks ago and ran it for 10-15 mins.
How to I determine if what I’m seeing is residual damage and the reason the exhaust manifolds were replaced in the first place? (I don’t know how along ago that was done). Or, is there something else going on? I assume it’s nothing to do with me the risers because it looks like residual coolant. Basically trying to figure out if I have a new problem or is this old news? What other components would leak coolant into exhaust ports/top of valves? Maybe the exhaust manifolds were a mis-diagnosis a while ago?
thanks
