thanks RC,
Do you know what size tap is required for the spark plug?
PS; Now I know for sure, NOT to work on my sons bus at night, cold, with lite rain. |
14mm plug tap. Most of the FLAPS have a double ended 14mm x 18mm plug hole chaser hanging in the tool section. |
FYI guys this is the tool I use if the top couple threads get messed up.
Internal plug chaser, it's magic when you need it most!

one of my mofoco's is a bitch to thread the plug into.I dont have a clue as to why.Ive checked it out it all looks fine.I wich these vw had steped plug holes to help keep em straight when putten them in .hmm a steped plug would be nice too. I have found that some time,some cookies,a cold non alcohoolic drink and some shade helps a lot.and of corse dont put a rench on the plug till you have screwed it in atleast 5 turns by hand/fingers/hose. I think Ill make some new cylinder covers(aka tin) that are like the early porch ones where the entire end (with the spark plug holes in it)comes off easely.that way I could get the holes where they need to be and have them seal to the head like thay should.(not realy seal they need about a .040-.080 gap, not the gaping holebig wide open non fittingworth a crap,and yes this go's for oe tins too.) the bergermans shroud of turincars I re did had over a 1/2" gap for the air to escape along the entire head serface at the valve cover end.it's kind of easy to see why those shrouds dont work so well when you have a look at whats goin on or not going on in there.there a pain to fix but probably worth fixing if you have one.and some look better than the some of the vw ones do.but the price should be around $200~300 for the setup including alt&mounts, pullys.IMHO.oops getting off track a bit.I use oil on my sparkplug threads too.and dont leave loose or too tight.remember the aluminum expands more than the steel plug does, so it may get loose over time, and need a little snug.or might not.and the expanding&contracting works on the threads too.so it's not just instaling&removing the spark plugs that wears on the threads but also the heat cycles take thier toal.( not to be confuzed with the eviel troal rideing on her menstrial heat cycle.) |

The number 1 cylinder blew the plug out with an insert attached to it. After I pulled the motor out I found the plug stuck in the fan! I looked in the plug hole and the threads were completely gone. Trying to avoid buying a new head or heads even though I know that is whats gonna need to happen eventually. So now I need to find a distributor for time-sert. does anybody know if you can buy them online anywhere? _________________ 1968 Beetle. |

This is exactly what happened to me blew out the plug with the insert. Can it still be repaired with another insert? Threads are gone in the head. |

I've used those sparkplug repair inserts from auto zone/ advance auto with success. those are the solid black inserts, NOT THOSE DAMN HELICOIL SPRING THINGS. those are for bolts only, not sparkplugs!!! but the black ones I've used with the motor still in the car. I just use bearing grease on the cutting tool thingy, do a turn, pull it out, clean the shavings off, regrease, do another turn, repeat. screw the insert in, use the spreader tool, hammer it lightly which spreads it out, and bites the head. and I've never had one come out. Sometimes, i'll smear the threads of the insert in JB weld before I screw it in, just to be safe. I dunno why people say it doesnt' work under heat. I've used JB on combustion chambers that had bad nicks, and filed them smooth, and its always stayed in tact. _________________ 1974 Super Beetle: Custom resto in progress

FWIW
I had trouble with one spark plug, first thought I cross threaded it.
Bought an inverse thread chaser, nice tool and not expensive, to find out
there was a damaged helicoil on that thread *damn*
I'll remove the head and put a 11mm deep copper Time-sert on there, cry once, you know.
Moral of the story: never ever use helicoils on spark plug threads _________________ Aug '58 pressed bumper SO23

This happened on my 1835cc engine about 7 years ago, the head rebuilder in the mid-1980s put helicoils all around. See my earlier post in this thread, I used a solid threaded insert to fix this (not a Time-Sert, which is consided the best, and I didn't pull the engine either). The threads cut for the helicoil and the solid threaded insert threads were the same.
I've used a solid threaded insert on #2 on my 1835cc engine for several years now, no issues.
I installed this while the engine was still installed. The insert kit will come with a tap if you have stock thread heads. This can be done with engine in the car. Use an insert the same length as your spark plug threads.
1. Use grease on the tap. After tapping, remember to clean the newly-tapped threads very well, with aerosol brake cleaner or solvent on a Q-tip applicator.
2. Use red Loctite on the insert's outer threads.
3. Use a little Never-Seize lubricant on the spark plug threads. Thread that into the solid threaded insert.
4. Thread into the cylinder head.
5. If the insert ever comes out when you change a spark plug, transfer it or a new insert to the new spark plug and re-install. _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each.

I've been using either copper or nickel anti-seize compound on my spark plug threads since 1976 and I've never had any issue with it.
I use a liberal amount of anti-seize compound and make sure it's worked into the threads and then wipe off the excess. I'm careful not to get any anti-seize compound on the electrode insulator.
With 14 mm spark plugs with 12.7 mm long threads, I torque the spark plugs to 18 ft lbs, which is equivalent to 21.5 ft lbs with dry threads.
I ALWAYS use a thread chaser and clean the threads in the cylinder head before installing the spark plugs. I can usually screw the spark plugs in almost all of the way by hand. If the spark plug holes are clean it should be difficult to cross thread a spark plug.
