• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Heavy Isolated Misfire Under Load



Before we condemn the cam.. what does the roller of the suspect lifter look like? If it's looking good, then the cam is likely not an issue. No metal in the oil pan is also a good sign that the cam is fine.

Is compression on that cylinder still an issue?
 
I meant to post a picture of the lifter roller. Does this look like proper wear?

That cam is staying in there no matter what until winter is over.
Now I'm gonna see if I can find an ICM. Then I'm gonna re do all my vac lines.
