Pop goes the motor

The head on the 9-5 is junk now. So now is the time to replace the weaker parts with better parts.

Basically no warning what so ever. Was idling at a stop sign after driving through town for quite a ways and I heard a small pop then the motor dies. So at first I was like WTF that's weird cranked the motor over and yep definately 2 dead cylinders.

So Dave () helped me push the car off to the side of the road to try to figure out what the hell happened. I crank it over again this time another pop and a ton ton of ticking. Look under the hood and sure enough I have a nice hole in my valve cover and I'm staring at the exhaust cam gear in the hole.

So tow it back to the shop, I take off to finish my trip to the Meyer store in another car and Rob () sends me this picture after he took the valve cover off.



Great. The cam gear decided to destroy it's self hence after taking the head off bent all 16 valves.

So to remedy this problem the computer went to Nick to get re-burned from stg. 2 to stg. 3, scavenged a new set of valves out of an old blown up 205R motor, rounded up a pair of T5 cams, ordered a set of GS upgraded valve springs and ARP head studs, and ordered a whole timing/balance gear rebuild set.

This should take care of the head next will be the bottom end once I melt down a piston.

Stereo.

I'll keep this one open, because it's your car.

Higher RPMS? Doing any porting?

That's the first time I've seen that happen to the cam gear! Nice work!

Well higher rpms is some what in mind.

I look at the springs as a cheap insurance policy in case I miss a shift.

Porting wise I'm going to leave it alone for now. I figure when it comes time for the bottom end I'll do that.

Had that here to finish up for you..

No need for studs or different valve springs(t5 only, the valves not cams) on that setup.

I had an -85 16v do that but chocked it up to first year. That is pretty wild.

I've heard of that happen to one person with the V6 motor. Sucks though.

On a related note, Tuesday night I pulled the head off of a friends Neon because her timing belt wore out. Ruined all the valves, but the pistons look OK. $350 in partslabor from the machine shop.

I'd rather a freak failure than have a failure due to neglect.

The tattoo is on Robs arm. I have an idea similar to that but I haven't gone through with it yet.

The pistons were fine just the slightest dings from the valves. Nothing a little green scotch bright pad action couldn't handle.

Not really, sometimes the bolts break when you torque them to spec.. ohh and sometimes people dont tighten them enough so the keyway strips and puts the cam out of timing...
so yea, torque camsprockets to 63nm!
