When I try to get my exhaust manifold back on I see there are 2 bolt holes
(threaded holes for bolts), one on each end of the head, where if I put a
bolt in the back one, the front one doesn't line up. The manifold is short
of making it to the hole. The only thing I can figure out is the manifold
has shrunk over time or something. There are 12 bolt holes for both the
intake and exhaust manifold and I know I only took out 8. Perhaps the
previous mechanic fudged his installation.

Should the manifold bolt holes line up exactly with the head holes?

Any ideas anyone?

Thanks,

 

yeah, the mating surface is definately flat. It looks like the exhaust
manifold has "shrank"? I don't know but the "width" from front to back
certianly is way off (about a quarter of a bolt width) and I cannot affect
it (pull it out) to make it work. Also, many of the other hole are off too
so I've been grinding out to make them work. I think some exhaust manifolds
may have a metal bar going across to ensure this doesn't happen.

Since you're coming this way I'll give you a couple of tips I found along
the way.

1. A breaker bar and my old favorite the pipe wrench have been invalueable.
I used the pipe wrench to grab the harmonic balancer while trying to get the
securing bolt off.

2. When pulling the balancer, put some kind of protector/washer at the end
of the crank so the balancer puller doesn't press into the threads of the
crank. I didn't do this and almost lost the thread to put the bolt back in.
Luckily I have a tap and die set where I could start the thread again.

3. If you can get a digital camera to take pics of how it was in detail that
would help immensely.

If I come across more I post but again, the breaker bar is your best friend.

thanks,

Read the thread,
Man you didn't need to replace the manifold! I hope you at least bought a
header. My bolt hoes were the same way. All surfaces had been machined
flat, all I did was file out the back hole since that was the one not lining
up and voila it fit. I've got about 3K miles since the MPI kit install and
no problem at all.
My advice is cancel the order. Spend that money on a file and use the rest
for beer and scotch...

Hey, Thanks for the advice. I did as you mentioned. I have a Titanium
grinding tip for my drill so I grinded it out. I took a lot of as it was
not that hole only and I have a little more to do to make some of the
bottom, center bolt holes to work but I think this will do it. I canceled
the order and am going to finish it up today.

Thanks for the advice,

bill

jeff-i actually have lots of room.....i'm doing a body off frame
rebuild so all i have sitting on the frame is the drivetrain! thanks
for the advice though! removing the fenders makes a whole world of
difference! i just received the mpi kit this week and i'm waiting to
have time to pull the engine and drive it over to the machine shop.
