I just got my new 3.4 DOHC home, and cracked the front timing/front cover. I have a spare one.  I guess I am going to start swapping out the covers tomorrow.

pics of the carnage

:shock:

You know there's no warranty on that!  

Oh yeah, if you look in the service manual, there's no mention of removing the heads or anything.

[3100MPFI]

yeah.  Fortunantly, I have a spare cover.  Only thing that sucks to me is that I have to remove the timing belt.  I don't have any cam hold down tools.

I will just get it done and time the engine later.

I saw a 55k 3.4 in the yard. I think someone tried getting the PS pump, the literally cracked that whole section off! I could see the timing chain!

[SofaKingWeToddDid]

dude, when you pick up a motor, dont hook the chain onto aluminum!!! make sure its steel and bolted on heavily!!! hahahaha wait, i bet thats what my motor in my car looks like, in 3800 form.

[3100MPFI]

I DIDN'T bolt it to that.  I had it bolted to the metal loop that is attached to that.  When I was lowering it, it was coming down too fast and when I stopped it, it bounced, and that caused the metal loop to TWIST.  It was that twisting that caused the aluminum to crack.

ben is sending me a set.

Here is more pics.






and I am GLAD this happened.  Check out this mess.

[Jay]

Now get the shit fixed and get it in your car...

nice belt


...and a local guy has cracked more than a few of those covers....

[somerset-regal]

hairy!

[Euro]

Damn.

[5speedz34]

Wow, I didn't know the engine hoist loop was attached to that bracket...er should IhavE?

That's nuts! Ohh and that belt is definitely almost gone.

[3100MPFI]

yeah.  I am kinda glad it happened, but I am kinda pissed as well.

I tapped the holes to pull the cam sprocket today.  I didn't have the bolts for it, so I will try to pull the sprocket off tomorrow.

[3100MPFI]

I got the front cover swapped out today.  I didn't get pics of the new cover back on, but I will get pics of that tomorrow.

Here is the broken cover.  Tomorrow, I think I will piss on it, then throw it in the garbage.



This is the new cover gasket.  It is THICK instead of being just PAPER like the 3100 one.  In this pic, I have it sitting on a 3100 front cover just to see if it can be used on a 3100.  Looks okay to me.



and how thick it is



And here is the engine with the cover off.



This is a closeup of the timing chain and tensioner on the 3.4 DOHC.  I think that when this is all over with, I will see if the tensioner can be added to a 3100.  Seems like a good idea.



These are the holes I had to tap into the cam sprocket to use a puller to get it off.



I tapped 3 holes, then used a grinding wheel on my dremel to enlarge the slots of my puller so that I didn't have to buy a new puller.



That is all for now.
