ITBs and brake booster

[zaq123]

I just got another set of OEM BMW rockers.. all have BMW roundel ...10 came in the bag and 2 were separate. Those 2 didn't come with eccentrics/bolt/nut as those other 10 or the previous set of 12 I got...

[zaq123]

what torque do you set on those cover bolts ?...

With ITB setup, vacuum booster gets its vacuum from only one runner, #3 cyl in the case of RHD ITBs. Rama states in his instructions that vacuum from one cylinder is such stronger than the vacuum block......

how was it holding up. I have brand new valve cover which is NLA at this point and it's warped ever so slightly. I agree with FF that rocker shaft retainer clip is somewhat on the way and gaskets just...

[zaq123]

you can put that cylinder valves in closed position, pull the retainer clip and slide the rocker to the side enough to take i peek. Little inspection mirror will allow you to see. also as a tip, if rocker...

Just to follow this up. It was a freak incident where brand new $40 ATE check valve failed/felt apart internally and was rattling inside randomly opening/closing with vacuum pulses. And the noise was...

I've seen some claim OE is INA, Veico, Febi etc etc ...Even if it was the case, I bet all of them are using some different manufacturer now from when supplied BMW. There are so many different versions...

[zaq123]

i was able to source a set of OEM rockers for $40 each and their pad quality is best out off of all above mentioned. They come with eccentrics and new hardware as well. So $40 is not a bad deal. I ordered...

wear on the back side of the cam lobe? there should be no wear at all...that's the position when the rocker/valve clearance is present. could be just old and tired valve train. If cam is original, good...

sorry I didm't see your question.. Yes, that is the hole I used with the spring grommet. Also that spring is NLA so I was found Mopar/Chrysler clutch pedal spring p/n 2643705 that worked perfect for this...

[zaq123]

this is what you need. Well worth a few dollars it costs. Take that tip off and touch the area of the engine with the probe to pinpoint where the noise is coming from


.....

[zaq123]

I returned them to IE so no, I never installed those....

[zaq123]

not advantage. Actually kind of a backwards move like going to carbs from FI. But if you are doing it to be old school/electronic free setup, dizzy is a must....

[zaq123]

if you are doing carbs, might as well go this route for the ignition.

...

[zaq123]

what digger said is my concern here as well. Old bearings can be reinstalled and I've read it has been done before if good condition with no issues. However if they had to shave it again to fit the shaft,...

[zaq123]

they don't compress evenly on the whole circumference so it's impossible to say what you are asking. New bearings are not exactly round and become round once installed from what I understand. What your...

[zaq123]

yes, extramely. Also scotchbrite and any part of the engine that see oil, is a disaster waiting to happen. Aluminum oxide and other abrasives dust in it will clearance everything else that you'd rather...
