Trying to find your post, do you have a link?
I found a small piece of steel in the intake, not sure where it came from. I'm in the process of pulling the motor, to do a autopsy. (It's about 1/4 in long)
Whatever it is, it has seen some heat.
I'm still leaning towards piston material, but hope to be wrong.
Best of Luck...
I've heard that Gen 3's are known for knocking off the top ring land on the cast pistons.
The Gen III just barely passed emissions. One solution was using collapsible lifters to reduce cam specs at idle, which helped.
Another was placing rings/ring lands fairly high up on the Piston, so unburned hydrocarbons couldn't "hide" there.
These gas engines will not tolerate detonation (none really do), and can break at the edge of the piston dome and ring land, yes.
Looks like a bad tooth filling
Have you had a chance to pull the heads and look around?
Engine is almost out...
THAT SUCKS MATE,
Engine is out, I'm driving it to Prefix in Michigan for a complete rebuild. It's getting forged pistons & rods, hotter cam, lifters, springs, etc.
Nice! Will they dyno it once they are done? Would love to see the specs on the new camshaft too.
Looks nicer than mine now
If they are unfamiliar with Gen III Viper engines, it might be a good idea to tell them the oil pan has to come off BEFORE the timing cover does.
Best of luck with your project.
Oh boy that's beautiful for sure!! Good luck
Yes, a dyno session is included with the rebuild.
Prefix is the premiere Viper engine builder in the country, they are the ones who built the engines for Dodges Viper race team.
You are in good hands then.
I'm curious to know what they find when they pull the heads.
