Someone has been in my CAMS?

How does on visually determine an NA cam from a Turbo cam? No real part numbers on them. Here is the reason I ask. The cam gears have written on them (painted) AND inscribed with both "E" and "I" which tells me someone was doing something.

Then I'm looking at the grind and it looks pretty aggressive and I have painted bands on the cams. Any ideas?

Also - just for giggles, I slapped the S60R Ex. manifold on to see what is looks like. This is much better than the stock one, but wait until it gets all ported and polished!

Whoa, NO CLUE whats up with the cams, thats insane. Maybe they're Piper Fast-Road cams? Someones been up to somethign with it. Anything done to the car when you got it?

Previous owner had done some modifications, but if CAMs were part of it... I'm sure he would have made some mention of it on the list when I bought it.

Another clue that someone was in there was... when removing all the bolts, all were metric (12mm) except on SAE... which tells me one snapped previously and was re-tapped.

hmm... that is rather odd... but maybe it is just that, the engine had some issues and the cams had to be replaced (odd, but possible... not probable)

And taking the turbo and manifold out... in the essence is not hard. Breaking the poking stuff face bolts SUCK!!!

Thanks Jesse and everyone else for the comments and encouragement. That's about all I'm running on right now. Well, I stripped two sockets trying to get the head bolts off.... thankfully I didn't strip the bolts. So, I'm headed out to find the best sockets I can find. What time does NASA/Ames close?

Also, I'm tempted to try an impact tool to break them out. I don't have pneumatic here, just elbow grease and Heineken. ANY SUGGESTIONS?

great job, I went ahead and pinned this for you

Out of curiosity why not go AWD on the vehicle? Or does that require too much modification with an 850?

My understanding from other threads and some posts here is that the AWD introduces weak links in the drive train. Plus - if I wanted AWD, I would have passed up on the 850 and gone with the S60R.

Today's Progress; Learned a couple new things today... like how to strip cheap sockets on Swedish head bolts. But there was some good too! The FEDEX man kindly dropped off my brand new "R" bumper - many thanks for George for making this available. :pizza:

I might even be tempted to paint it black :huh:

OK - most everything external has been removed. Now for the fun fun stuff!

Ladies and Gents - boy and girls of all ages... this is what my pistons look like after 105K miles of service. The cylinder walls are actually in really good shape probably due to all that good ole Alaskan Mobil 1.

Here is an interesting part. I confirmed today that yes indeed, I was running NA cams unbeknownst to me. Anyway, when I removed the head I found that #5 cylinder exhaust valves were hitting the piston. Check the picture above real closely (#5 is all the way to the right) and you will see two shiney marks on the upper portion of the piston head. I also confirmed this on the valves as shown below:

I also found that the intake valves on #2 were hitting the piston as well.

Well, tomorrow it another day. I need to get a 12 point socket to get the con rods off and everything should be broken down by then. Plus I ran outta beer and it was too late to crack a bottle of Cab. Take a look at my garage and you wonder why my wife is on my a$$ all the time :unsure:
