Spark plug removal issues

Unread post by va3rjs » Sun Aug 28, 2016 2:46 pm

Hi everyone

I am new to thE forum, but not new to Corvairs....... I had one 45 ears ago, when they were not considered Clasics :tu:

Jump forward 45 years, and my son talked me into getting a classic so we could do car shows and cruise nights......he figured Chevelle, a Camero, a Firebid or something GM with muscles....... So why not a Corvair........a car near and dear to my heart!

Ok enough about me....lets talk about my ride:

Just got a 1966 Monza Convertible.....for what I have been able to determine so far it is 95 HP Powerglide car...... 2 door, white top, black and white I interior.......seems to match the tag numbers

Only had it 4 weeks, got all the electrical and mechanicals done so it would certify and got it registered and on the road last week..... Went to,our first car show on Friday night..... On the way to register it started running pretty rough......this is where my question starts

I figured the best thing to do was to check the plugs to see if any were fouwled, simple job right....got my tools out and the first plug I try to pull, loosens but then is very hard to unscrew, with a plug socket and wrench......I have never seen this before on any engine I have ever worked on........

Don't know if it was the right method but I did a sea saw( loosen a little tighten a little and so on plus a little penetrating oil) on one plug and got it out......is that an ok method to keep using the next plug seems even tougher?

Also the plug I got out is an R44XLS, which I have not seen for use in a Corvair application........anyone have any feed back if this is a supported plug or maybe what might be causing the hard extraction?


Sorry for being so long winded here.
Thanks

NGK BR6ES...Is one appropriate plug and heat range I believe

Your plug is one step hotter...resistor plug (Which is fine)

But I don't think a projected tip is appropriate and yours may be just that.....

Unless your threads were some sort Helicoil and are coming loose ...your plug is a little warm

Does any one happen to know the length of the R44FF plug from the bottom of the seal washer to the end of the plug barrel or rip......I am wondering if maybe the ends are car ones up and I am dragging that through the thread.........?

http://www.sparkplug-crossreference.com ... LCO/R44XLS

I don't know .....This chart is just kind of saying it's a projected tip

Those are either shorter or longer .....Depending on the reading... I don't think those are right

That 44 FF is looking like a projected tip too

Some information suggests it might be a better plug ...

but after research the folks who used them seem to be unhappy with them

NGK spark Plugs have a special plating

With that, they thread in and out of an engine easily and u do not need to lubricate the threads

They come out easily years later do to that coating....I have been using them for almost 50 years

So the heat range or the 44 is ok according to this chart...But at least one guy says projected tips are not good 4 corvairs

Doing this on my stupid handheld phone while I'm going down the road is not going smoothly and I'm adding a lot of chatter my apologies

Thanks everyone.......the second plug did not come out very well and I am not sure the see saw method ( turn out a bit turn in a bit and repeat going a bit further out) I think it was probably more like a tap........I see what looks to be aluminium chips in the spark plug hole...... So sad......and 4 more to go......I can't help but think a little anti seize compound would have prevented this with the AC plugs......

I see help coils, new heads or an engine rebuild in my future......... :td:

Only 4 more to go :(

No, there are days like that. This forum is a bit slow. During the week I tend to check it 2-3 times a day and there isn't a ton of activity.

The 44 XLS were probably put in because it burned oil & was fouling out the plugs. A longer plug thread length will not foul out as fast. What you have is carbon or burned oil on the threads making them hard to remove. Keep the PB Blaster/WD - 40 coming, don't go to fast. What does the engine number say? It's right behind the oil filler tube. My owners guide says AC-46 for the Turbo-Air 95 HP& AC-44 for the Super Turbo-Air 110 HP & the Turbocharged 150 HP.
