stripped spark plug maybe a big prob

[seven]

The other issue the car has is a stripped spark plug hole in the #2 plug. has anybody had any luck repairing this? I bought the car with this problem and was hoping for a quick fix I do have another complete motor but wanted to rebuild it before I switched motors was told a heli coil would work and was just curios to see if anybody has tried that before. The car is a 1993 325 IS 5 speed car

Yes, I have had success with spark plug threaded sleeves, not heli-coil but the threaded inserts bought at advance. I do advise that if you take it to a garage that can do this when asked with out hesitation, if they pause, or look at you funny at all, go somewhere else. It doesn't mater if its a BMW or a ford 4.9L v8, the technique is the same.

the exact same thing happended to me. they put a thread sleave on but that blew right out the very next day. i had to get a new head and my timing had to be redone. cost about 4 g's if i remember correctly

If done correctly they won't blow out and are stronger than stock threads. From what you said the garage that you took it to didn't do a good job, and/or used an inferior part.

Let me just clear it. Is the setup the same even with Mazda's. I have a problem with my Mazda spark plug wires and maybe i can use some info from this.

If it takes a spark plug, the technique is the same. Those thread repairs will work on any damaged spark plug threads. However it must be done correctly, or they can back out.

I did the repair worked great no probs Thanks for all your help

Use anti-seize so you don't have to worry about them sticking and backing out from them rusting together. Actually you should always use anti-seize, the copper stuff is better than the aluminum stuff. (try not to get anti-seize on you, the shiny gunk gets everywhere)

heli coils are a good proven problem solver, id suggest getting someone pro to put it back together for you, it might cost a bit more but its peace of mind.
