the seller claimed 89k on it and said he had it sitting around since 1998. It was clean as inside.

I ran run in oil for a bit then switched to HPR15.

Just got the cam out and its clean as! but has the typical lobe tip damage.

Post analysis time!

This is bs lol. How on earth is this still like a 50k engine on the bottom end?

I beat the absolute shit out of this and I expected the bottom end to be shredded and its perfect lol.

Added some pics of the cam damage. As well as damage from overheating resulting in seizure.

A testament to the engineering of these engines as well the high quality oil Penrite make. Those UOA were not wrong.

that is amazing inside man wayyyyyyyy clean!!!!!!!!!!!!

[vlad01]

I know right and the crazy thing is even that brown staining just wipes off to reveal factory clean casting with just a rag.

This engine has over 300k on it now.

Do you want to have any bits? I only plan to keep the crank and rods. Your welcome to the heads and block. I already have some so I dont need them but its too good to toss.

[psyolent]

nah i am good - thanks though

[ejukated]

Looks good, I've always been impressed by high milage engines that have run Penrite including my own. I recently stripped 2 ecotecs that had similar usage and the Penrite on was nice and clean on the inside. Other was my mates which always ran cheap 20w-50 oil and there's was noticeable sludging that wasn't there when I built it almost 8yrs ago.

Is that failure mode common for Buick cams?

[vlad01]

Yep, every high mileage buick cam I have seen has this case hardening coming away in my own experience.

Duggan's commented on this when i asked the question. That its the poor material the cam is made from considering the lifters do not suffer any damage. Only the cam does.

yeah I think theres a lot to be said for using reasonable oil and regularly changing it!
