Really Stupid Question but I need to know

Recommended Posts

Ok, I maybe killing a dead kitten here but, I am really concerned that I may have already screwed up big.

Is there a difference between the stud bolts for the intake side vs. the stub bolts for the exhaust side? It seemed that one was heavier than the other and one turned in tighter than the other.

Even more concerning is that there are two different part numbers.

Tell me I am not imagining things.

Thank you in advance!

The question is not that we broke a few rules or took certain liberties with our female guests.

We did ;)

as long as the diameter and thread pitch matches the holes, and they are not too short your good. I believe the only difference is the length. Stock exhaust manifold is thicker than a intake at the flanges. I got my exhaust studs from AutoZone. Don't forget to loctite the exhaust studs and use copper nust. I've got misc spare studs in my stash but I'll be away for a week. Feel free to call me.

I had the same thought when replacing my exhaust studs. I bought both sets from Maximillian and believe the (2) are different colors. I think the threads are the same - but am not sure.

As long as they thread smoothly into the head you should be fine. Ditto on the loctite and copper nuts (for the exhaust).

a compatible (in length and thread/pitch) exhaust stud from a Saturn (IIRC) that has an Allen hex socket in one end that allows you to install it into the head much more easily--and hold it in place when you're trying to back out the nut next time you remove the manifold.

Probably easier to find locally than the OEM studs...

yes I recall that thread too but didn't follow up as I already had my new studs. OEMs are available at dealer but may have to be ordered, allow a couple of days to get in hand

Thanks guys, I was really worried for a moment

I decided to double check the bolt length, they are both the same as well as fitting both intake and exhaust manifolds, looks like I have thread to spare.

Again, thanks!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
