EREBUS

For those who installed the looped fuel rail, did you have a problem with installing the EGR's afterwards? The rail is in the way of the EGR ports.

It is a very tight fit

WANTED!!

I used a Dremel to aid in fitment.

EREBUS

Well, I thought I did something wrong. lol

Time to get out the hacksaw, pry-bar and duct tape!

on a stock car is there any reason to install a looped rail? I have read a few threads regarding cylinder 8, would there be any reason for concern on a stock motor?

Joncl

No since you are on stock boost and you are not over clocking the injectors

EREBUS

Cylinder #8 has popped on stock m113's and m113k's for years now. $400 for a little insurance is not that bad? Besides, it's a blast to install.....

Hulk

Stock cars? Or cars that were modded and then sold back as stock?
The rail and injectors are sufficient for the stock boost

A lot of cars were sold after the motor was already hurt but the previous owners took off all mods and sold as stock and most probably popped after that.

Hulk

Also If you still wanna go with a looped rail then update your injectors while you are there

Joncl

I was searching for it not to long ago but couldn't find any threads indicating that, can you point out where you read that?

chiromikey

While I won't knock the premise of never being too safe, I've been around this board for a while and very much in the loop during nearly every mod development and I can't say that I've heard this before...

EREBUS

Retract your claws, ladies. If there is fuel starvation, for whatever the cause, #8 will go first. Not a problem with #8 cylinder.....just first to go. Ask a Mercedes tech if there was a cylinder failure....which number cylinder is the most common to give?

Like a bunch cops at a Dunkin Donuts half off sale. Damn.

EREBUS

Hell, similar design in 4.6 and 5.0 mustangs. #8 is hottest/ leanest

chiromikey

I don't think anyone is arguing why #8 is the weak link, just your claim that there's been a lot of failures on stock motors.

it is more than a tight fit, you can forget about it if this a b i p rail. i gave up. the fittings are gigantic. I've got new low pro fittings and hose but havent effed with it.

EREBUS

I said #8 has popped for years? Not a sh*t ton, but this is the culprit cylinder for failure. Heavy/repeat acceleration with a stock m113/m113k motor that has a vacuum leak.....#8 will feel the wrath.

EREBUS

You are dead on. The fittings are my problem!

chiromikey

Yes, you said it has popped for years on stock motors. I've been around here for years and this is the first I've heard of that.

EREBUS

So since it's not common on MBWorld, it doesn't exist? Makes sense

Mine cracked (modified engine) a few months ago and was told #8 is the first to also go on a stock engines with lean problems. M113 and m113K.....more common on m113k due to boost. You seem to have free time.......how about you call a dealership and report back to all the wonderful children here on this forum what you have found?

Apology is needed here, apparently. I'm sorry. Fuel delivery is not a problem with our engines.....even if they go lean on a stock motor. Because, spending $400 on a little piece of mind is a waste. If it's not on this forum, it didn't happen. If you've been a forum member for longer than someone else, your rock-paper-sissors abilities are of legend.

chiromikey

Lol, go back and read my first post if you think I'm arguing against peace of mind. Then read my second post if you think I don't agree there's a fuel delivery problem at number 8 (on modded motors).

Do you think I never leave my house? I don't need to call a dealership since I know a few techs and service managers personally. We've talked in great length about these cars and modding them. And do you seriously think that if it was a problem on completely stock motors it wouldn't have come up here? The membership numbers and traffic volume dictate otherwise.

EREBUS

lol, right? uh, maybe my piece of mind comment was towards others? (hulk)

i think we are bonding, mikey. oh wait, you seem to think it can happen only to modded motors. nevermind, carry on

well, sh*t.....that's rich mikey. i work in the car business. maybe, just maybe with Grapevine Mercedes in Grapevine Tx on a daily basis. but, i don't have 4,000+ posts on this forum, so your rock beats my sissors.

benzworld has posted a few #8 cylinder problems with stock motors. i would venture to say more people tune on this forum than benzworld. they're liberal tree huggers over there, you know.

i want to do a smilie as a response. but, i hate smilies. i shall leave no response to that stupid a$$ comment you just posted, then.

chiromikey

All that cut-n-paste work and still offering nothing to back your claim. Nice job

I'd like to read up, can you please PM a link to the benzworld threads you're talking about that link stock blown motors to #8 fuel pressure. With so little traffic over there there's just not much coming up on a search for blown motors.

Hi

In regards to the vacuum leak. Can I test if my engine currently has a vacuum leak? Where is this leak usually from and can it be heard?

Regards,

OZZYAMG

i have seen cars that have had a 180mm crank pulley, cooling, rail and injector destroy No 8 (5 cars)
Does the rail solve the problem NO! Does it help a little with fuel starvation YES.
If you think adding a looped fuel rail and injectors is going to make your engine fail safe then you are mistaken.

this one being the latest. Owner of the car is a board member

Shardul - Were the cars that failed logging AFRs on the #8 bank ? I have seen quite a few modified cars without proper logging setups and it just baffles me. That said, even with my setup, I am still concerned about the fuel delivery (I would prefer larger pumps, line, and a return)...
