Exhaust Manifold/Intake Manifold mPi, continued.
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, "serg" <none@none.com> wrote in message news:wbh0b.3073$SQ.1681@newssvr25.news.prodigy.com ... > is the mating surface on the manifold completely flat? it might be warped, > causing it to just barely miss the hole. i just received my mpi kit and > will be installing it in about a month or so...i'll keep reading your > posts... > > "William Oliveri" <wuji@bigvalley.net> wrote in message > news:bhs4um$2jkqf$1@ID-193866.news.uni-berlin.de... > > 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.

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...

Re: Exhaust Manifold/Intake Manifold mPi, continued.
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.

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.
