thanks guys for your thoughts, truly appreciate all assistance

so the bolts i purchased for the manifolds were 10.9 steel, M6 1.25 pitch and length 25mm, maybe was 30mm but im pretty sure it was 25...it matched whatever came out of the car. The lower part of the head had studs, so we just used new copper lock nuts

i hear what you are saying about the possibility of my machining the flanges may have been the culprit.

That being said...the flanges were not smooth when arrived, but i assume nothing in cast iron was or were.....tony wanted me to get just a hair smoothened up so they would sit flush to the heads better.....

i cant say i know exactly how much was removed , but i know it was minimal and uniform

now remember i had it done on all four parts....and the right side fit fine.

i dont think the machining of the parts is the cause of the fitment issue...but obviously i cant say 100percent

tony honestly doesnt have time to go back and forth on my car by trying additional gaskets etc for space.....he told me have a exhaust shop heat bend these and be done with it....im not gonna argue with a 40 yr mb mechanic and get on his bad side...plus he is busy with 3 pagodas and a 300sl roadster coming in. ....obviously as these tri y are rare neither of us had installed them before.And i was going by what i researched here.

Hi there vdub,

I am really sorry to have you be going through all this, especially since you've been sharing your excitement & planning with us all this time! What a bummer....

It sounds as though your tech, a busy man, cannot see loosening/removing the driver's side downpipes or exhaust manifolds again.

Stating the obvious, at the very least, the left downpipe will need removal to be 'fitted'. Can't be done in situ I think, as the chance for collateral heat damage to many other components/systems is almost assured. *

Looking forward here, I'd imagine the forward runner is assembly marked by now from it hitting the bell housing so there's your 'adjustment' reference, if not already marked from below. You'll at least have your reference to go by.

Good luck man.

M

* Fifty years ago, a dealership service dept. caught the interior of my 3.8 MK2 Jag on fire while gas welding a rear suspension component.. Unforgetable. Forgive me please, but I had visions of those W126 fuel lines running up the firewall there & over to the motor....

so the update is this....

went to a few other exhaust muffler shops...all have said that heating with a torch and bending the pipes is not viable

they believe that part will need to be removed, cut and made correct position....

shops each rechecked the mounts....all confirmed to be good.


that will be that i guess

Good man.

I am sorry you've had this impediment, truly!

I trust you'll get this totally sorted with a minimal expense & we'll be able to vicariously enjoy your win when done via YouTube, etc..

Your exhaust is taking a lot more personal energy than my experience [2017]... Much luck with the final stages!

Please DO keep us BW guys posted as to your wins..

MBL

Misaligned

I bought the tri y’s and down pipes as a set from a vendor affiliated with Japan partners and located in the Russian Federation area. Paid a $1000 dollars in total.
I installed them when I did my head gaskets late last year. I had no problem with the passenger side down pipes but the driver side was about a half inch off. I was able to adjust that much by cold leverage.
After I was done with the rest of the work I had the car towed to a muffler shop for the exhaust work to be done and they were able to tweak the pipe alignment so that it was parallel with the body rail of the car. We used to call the luck you’re having Sod’s law back in England. Sorry for your troubles but you’ll get it sorted.

My research indicates that this part is an aftermarket for the driver side, LH steering wheel. Is up to you if you want to give it a try or not, I have no affiliation with this seller, I am only trying to help you.

Your luck reminds me of mine when I had decided to get Euro headlamps.. I got a “ready to go” set from someone for $650 and then spent about $800 fixing basically everything. It was a really bad feeling at the time... but eventually there was a light at the end

Your project is a lot more expensive and critical to the car than mine was! Before feeling too hopeless, would it be possible to back out of this project (put your old parts on) and sell what you have? It can feel like giving up, but sometimes things are not worth it ultimately. Hopefully, things turn around though and you can finish it

im plowing forward.....

some will recall around mid 2017 my 500sel had a knocking noise that ended up being a worn cam....i went through about a year plus to get that car entirely sorted....at that time we had to make the decision to either just let a 190000 miles car just be as it was and not proceed with work, or to do it and do it right.....as the car has been with me since new, when i was 7 decision was made to get it all fixed up, so everything has been done on that car and are 5 digits $ deep in 18 months....but its awesome

about a month prior to hearing that knocking noise on the SEL. i made a spontaneous decision to buy the SEC, same yr, same color, same miles as my SEL

i thought well wont that be cute to have both...my wife will never know

well of course the sec has been full of its challenges as documented here....(temp issues that never really lowered even after doing all cooling syts, ) ( lowering that never really lowered as it should have, Etc). and last yr i was tempted to just cut losses..i told my mechanic to check the motor and see if its any good

he said compression was 180psi all around so i said heck with it, lets build it out, and i spent 1500 on the tri y set which now is going be doubling in price soon, for my 10-15 hp. LOL

Also decided, that on this car, why not paint the lower trim and body match it , as i wont do that with the SEL, and then i thought then why not basically do a amg tribute, so bondavi and macdeity helped me source body kit gen 1...I already have pentas.....so that is all next after exhaust is sorted


then a sound system

then drive it lots

i think of it this way...if i didnt buy it, it may have been lost in the hurricane flooding in houston in 17

anyways, thanks everyone...bearwith me
