Fixed stripped spark plug hole


Recommended Posts

So a while ago i decided to change the

plugs for the first time since I acquired

the car. Got the tools layed out and

started replacing them. First one comes

out fine but the second one I can hear

metallic crunching noises. I take it out

and am threading the replacement in.

It threaded all the way but wouldn't tighten

down and seemed like it was skipping a

thread or something. I had to drive the

car to and from school and just left it

alone and replaced the rest of them.

It has always bugged me so I was

researching on some fixes. There are

helicoils timeserts etc etc. Then I saw

that someone used a "back tap" and it

fixed there problem. I drove around

with this problem for a while then finally

decided to fix it this week as I had off

from school the whole week. I ordered

the back tap and it came in today. Got

the gloves on and the tools ready. It must

have only taken 5 minutes from start to finish.

I'm glad this solution worked and that I didn't

have to spend $$$ on costly repairs. Here is

the item and it has honestly worked wonders

and saved me a lot of $$.

Sorry to be the pessimistic one, but that may be a short term fix. If the plug was rotating in the hole and not tightening, your threads are probably (IMHO) almost gone.

I had this happen and used a thread chaser to clean up the hole. Worked like a charm. A couple of years later after another change of plugs, BANG the plug blew out of the head at highway speed. Threads totally gone.

Enter stainless Timeserts. Used extensively by Porsche owners on aluminum heads. Not only a permanent fix, but much better than screwing into aluminum. Don't even think about Helicoils.

You may be ok, but beware.

With this you put it all the way in the plug whole at the end where the threads are supposed to be good. Then you tighten it a little and back it out. I could feel that the threads were all there and in some spots they felt like they got cross-threaded. The plug snugged down fine and I should be good to go but will check it time to time. Thanks for the head up!

    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
