tap question

[controlled insanity]

i had a spark plug jumping around unscrewed and loose between a coil pack and the engine block, ruined a thread or two on the block. should i just run a tap through it then change the oil?

let me guess, ford mod motor?

Coat the tap in grease, back up after every quarter turn, and you should be good.

lotta people said that to me today.
so where is a good place to pick up a tap?

 

[dave89iroc]

odds are, just tapping it won't hold, there are only a couple threads to begin with

 

[standy]

If you know the thread pitch, I can hook you up with a tap to borrow. I am not experienced with these motors- is it a metric plug? If so, ou can probably install a heli-coil.

I have that Timcert Kit. It fucking sucks. It is $120 per cylinder and no guarentee it'll hold. Best thing to do is replace the head.

Hmm. I have never had an issue with them.

i have no idea what the thread pitch is. this is shitty because its my only DD.
im guessing that i need to remove the head?
im screwed if a tap doesent work.

some of the heads cut well and some don't. depends on how oxidized the aluminum is.

Do yourself a favor. Replace the head. The problem I have doing them is half the time the aluminum is so oxidized that it crumbles as you tap it.


Of if your are determined to reuse the head. Remove the head and have a Time cert proffessionaly installed.

Odds are seriously 50/50 Pulling the head isn't that bad if you have hand tools.

i plan on pulling the head while i tap it. time to change head gaskets.

Just measure the threaded length off one of your current spark plugs. If it is under 1/2" use the short kit (TST-4412), over a 1/2" use the long kit (TST-4412E).
