So I've been driving about 100 miles a day half on highway and since putting in the seafoam for High milage (128,128 miles) and driving it about 4 or 5 times on the highway it has gone away and haven't heard it on first start up anymore. Something was definitely sticking then but I'll keep this thread posted on any change. Thanks for the video link above. I'll watch it for fun still.

 

That sounds kinda fishy to me......maybe it was the vvti cam gear.

 

Any specifics on the type of seafood? maybe clams?

 

probs seafoam?

While i always state oil cant fix any defects, try to run a thicker oil.

I'm going to try that at the next oil change. It's been pretty good 👍🏻good Rn with almost no chatter on 1st start up for the day.

 

I wouldn't put seafoam in oil.....at least not in an engine like the UR.

About the only thing I would use is valvoline R&P because it has been shown to work and I've actually been able to address some cars oil consumption issues without having to directly soak rings with it. Not going to work magic or anything but it's essentially a gas engine version of the Cummins diesel restore oil that is also known to work very well.
