No takers for my question?

Only time cod tell how important it is to have that coil screw to the cover. I would try to find a cheap fix. I think they sell a kit at auto parts stores that is specifically for drilling out a broken screw/bolt.

 

I would leave it broken unless things started misfiring.

 

ditto .

 

its only a matter of time till it pops off... go buy an easy out kit..... or, if youre lucky, since those bolts are only supposed to be a little more than hand tight, you might be able to stick the broken head back on where it matches up the sheer mark and loosen it... ive had luck with that before with a broken bolt.... or if any of the bolt is peeking out of the hole, try to turn it with pliars... should be an easy fix since those bolts are supposed to be like 12lb/ft or something... maybe its 12lb/in.....but since you snapped it, im gonna guess you had it WAY too tight

 

So in other words I'm once again on "borrowed time" just like (if you remember when I was posting about it) loosing control of the climate control and steroe. For which by the way has been working fine for the past few months ever since I gave it a few love taps. I'm bringing it in a few days to get it drilled out.

 

It sounded like taking it to the shop was in your sphere of possibility anyways.
If you take care of it one way or the other before you have misfire problems (if that comes up), you'd be avoiding having one car down for a period of time.

In my case, I no longer have an extra car so that would be a factor in my decision.

 

I guess the bolt is broken off flush, since I don't read any thing about putting vise grips on the bolt.

Irwin makes a left handed drill & easy out set that sells in machine shop supply places, try travers.com,

Center punch the broke off bolt as close to center as you can then drill with a left handed drill with your drill motor set to reverse. A lot of times this will back the screw out. If not go with the easy out.

 

if he does this with a reg left handed bit, should he do it at low rpms?

 

The belts are a relatively simple DIY.

 

You better price a new valve cover & gasket.

I'm an industrial mechanic & most of the time I work in our plant's machine shop. A regular drill won,t cut a good extractor. A lot of times extractors are broke because they are biting into the bolt & thread wall. Then a thread insert will also be needed when the bolt comes out to give good internal threads for the new bolt.

 

Thanks for the education. That answer was what I was thinking but didn't want to admit to myself out loud.

 

^^^ good points.

it will take a carbide drill bit to drill an extractor out. VERY FRAGILE drill bits. I've done it but I broke the drill in the process.
