I was coming home from work the other COLD
day & had to stomp on the gas to merge onto I-70. I think I probably hit 6k in 3rd with a cold engine when I felt a big loss of power. My fears were confirmed when I popped the hood. Steam from under the IC. Looked like it was coming from between #'s 3 & 4. So I'm telling myself please let it just be the head gasket. Well I started on it today & when I pulled off the cam cover there is the #2 exhaust cam follower in two pieces just laying there on either side of the gallery. Has this happened to anybody else? And if so, how much damage did it do the valves,springs,seals & lash adjusters? Could it just have been metal fatigue, I didn't here a pop or any other horrible noise when & after it happened. Do i need to have the valves done? I hope not, funds are tight what with the new house & natural gas prices almost double from last year. Any advice is as always greatly appreciated.

Thanks
Steve

You probably need to apply the attached problem solving schematic to this situation.


Where were the broken pieces? If they just fell down into the low spots, collaterial damamge (I love that term) may be minimal.
Your biggest worry might be that the valve got bent, so you need to make sure it desn't bind in the valve guide.

It's hard to tell from a photo but it looks like the metal smoothness of the affected lobe is disturbed, ie wiped a bit. It isn't worn that bad though it may wear faster than the others in the future. Inspect the adjacent parts and check the valve for binding. If all seems OK stick a new follower in and start the camshaft memorial fund.

Thanks Pete I needed a good laugh. Hopefully nothing but a follower & head gasket for now. Maybe I can talk "she whomust be obeyed" into saving for a new cam, "hmm maybe something with rolloer on it & while we're at it why don't we get the head cleaned, you know real good, almost
"polished" hurr hurr:-)
Thanks Again

Steve,
If you got the a good "feel" using a valve spring compressor, you might not have to pull the head to check that valve for bend. But don't let me stop you if you feel more comfortable doing it that way.

On that cam lobe, I might be wrong, it may be fine. It's hard to tell from the picture. Don't panic, it could be many K miles before anything happens.

MMedic. That flow chart has been around for a long time. I lost my copy awhile ago and just came across that one on the web real recently. If i didn't know I would swear if was a propritary process that Ford developed. It sure reflected the problem solving mentality of many.

Pete thanks. I wish I didn't have to pull the head, but when the valve stopped working it blew the head gasket. Thats my project for today. Then back to work tommorrow, then the weekend and I should be able to get it back on the road. Can't wait, I'm driven Dads spare Buick Century since the VW is in a coma at the moment. I'm havin aome serious Boost withdrawals here;-)

If you can, measure the break away torque on the head bolts. I'm curious.

OK Pete, where did you get the classified Air Force document? There's harsh punishment for those who divulge secrets!

From the looks of that cam lobe behind the broken follower, I'd say you need a cam as well....
