Question Found an engine !

My 1986 6.9 L is shot, I found a 1988 7.3L/ C6 for a good price, the guy sais that the C6 on the 7.3L is shot so I will just buy the block. Question: will the 7.3 have the same bolt pattern on my bell housing, I also have a C6 auto trans.
Thanks

Best of luck Saigon, I was kind of shocked when I saw the pictures of your motor.

The 7.3l should fit fine. I would put on a racor fuel/water separator system and make sure you use the 7.3l glowplug controller.

I can't help but think that that manual glowplug button of yours may have somehow contributed to what happened to your motor.

Auf Wiedersehen,

Sebastian.

I don't think there is any way that manual glow plugs could have anything to do with popping the head off a valve. That looks like plain component failure to me.

Think about how many times that valve opens and closes every minute the engine is running.

Almost 350 times a minute at idle RPM.

Thanks for the info ! Actually I did find out why the valve dropped,it all boils down to the two small 1 cent retaining cups that holds the valve stem at the top of the spring, I found them when I took the valve cover off, the inside of the cups were worn out and smooth, it was a component failure.All the glow plugs are in good condition but I did see a few small marks on one piston head probably from a fried tip from the previous owner.In conclusion a 1cent part is costing me 1500 euros !!Thats the way it goes, philosophically speaking you can
break a $1000 tooth by biting into an apple LOL .
