Anyone in Michigan with OB CIS knowledge?

In post #6 i posted



section 25-6 of the WSM has a control pressure "warm" 2.8 - 3.2 bar
without vacuum
and
system pressure test value of 5.2 - 5.8 bar

Fuel Injectors opening pressure is 3.0 - 4.1 bar

so control pressure at 5.1 bar is way hi, and system pressure was approx 5.15 bar is fine.
did you look at section 25-6 in the manual, it may help.

Got back at it today. Finally got pissed off and pulled everything with the intention of getting it all "right." Pulled the ENTIRE CIS system out of the car, spider, upper intake, FD, WUR, lower intake with TB...gutted it all the way down to the valley...get everything clean and checked and then back in...those cheap enclosures [$240] really do the job. I don't have a garage at my house so it's been hard to get out and work on the car in the crappy weather we've been having. I guess 3rd times a charm...wait, I think it's the 5th time I've torn down the FD...oh well, I get better at it each time I go for it. And no, it was not leaking after the last rebuild, but I think I may have been a little over zealous in the reassembly by putting it together before the Indian head set up...hoping that I didn't accidentally plug the metering hole. The WUR is free and clean...finally. Looks like I have good flow too, just would rather have the bigger flow pump by a name brand instead of the cheap p.o.s. that I have in it...no telling when or if it will go out. I'll post more of what I find when I get the car back together.

Thanks for the help,
Josh

Way to go Josh.
I hope you find where the issue is.
I know how it is when you just don't feel like working on it, but then when I do get at it, I seem to get so much done and wish I had started earlier.

Good Luck

ok...who dumped marbles into my engine? J/k, but seriously...it sounds like there are marbles in the engine...don't know if it's because the oil is so cold or what. Tried cranking it over and it sounds horrible...I really am considering not trying again until it warms up... I don't know if it is a predetonation knock or if it's a rod bearing or if the timing is all jacked up by a broken cam. I checked via the oil pressure gauge on the dash...yeah, I know, it's an "idiot gauge", but it was showing what I would consider high average oil pressure during cranking. I also checked the timing via marks on cams and at the distributor all lines up. All I did was clean the above listed components and replace vacuum lines... I hope that this isn't the death of an OB euro...although if it is...anyone interested so I can get the S4 from Stan? Just looking to get this sorted out next...guess I don't have a choice at this point.

TIA,
Josh

Josh, I wish I could help you with this but I do not know this car.

The marble sound scares me.

At this point unless someone else on here can give you some step by step experienced advice, you better wait and get help.

I would post a request for help on Rennlist if you have not yet done so.
You really need someone that can come over and go through it with you before you end up damaging something.

IMHO

Brad,
I updated the same on rennlist, one thought is that it may be vapor locking with fuel causing the car to become a gas "diesel" through compression explosion of too much fuel in the cyls... don't know...trying to look for a shop that knows 928's and is probably going to bend me over, but I want the car running before attempting to get rid of some other projects so that I can put Stan's s4 on lock down...there's something in the pictures on that car...makes me want it REALLY badly. But then again I have had the 928 bug since I was 10. The 79 euro is my 2nd 928 and currently my only 928, but I have been looking for another. I may have to take it to the other side of the state...might call Dennis today and see if there is anyone that he would recommend, saw an ob engine on CL near here, don't know how complete or even if it is usable, but for they are asking $750...still including what I have into the car and parts at this point is less than 2 grand so I'm still ok...I paid more for the fuel tank than I did for the entire car...lol

Thanks,
Josh
