i wanted to do a compression test so i went to take off the spark plugs and they was very hard to get out and was almost seized into the head now i wanted get the new plugs or the compression tester back in the holes they will thread in abit then stop liek there is dirt or **** in the threads how do i go about cleaning them out o is it best to buy a tape abd retape them to really clean them up

Remember we dont have that many threads. So you may actually be at the end of the threads. Take a cue tip and tape it to a pencil. Spray some wd 40 on the cue tip and go around the threads

where do you get a foot long cue tip at lol. yes i know there is not many threads but it feels like i get one and they stop kinda like cross threading something but i knwo im not

If the threads were cross threaded the threads on the plug you removed would be screwed up as well.

i work for tires plus and we just had a customer do his own tune up. he now needs a motor lol. he didnt blow out the spark plug "hole" before removing the plug. there was a bunch of sand in the head and now it is inside the motor. he then cross threaded a few of the plugs. we were able to tap the head (on the car) and get the plugs in there (after spending a lot of time making sure we got out any metal shaving from tapping the hole) the car runs a little better but he has low compression on cylinder 2,3 and 4 and smoke from the pass side tail pipe. the sand messed up the ring seal to the cylinder wall (basically acted like sand paper on the cylinder walls). this is a very common problem (sand in the motor after doing plugs and also cross threading the plugs or even having a seized plug come out bringing the threads with it) it sucks man....... oh well just use it as an excuse to do an upgrade.... ported heads, pi swap, or even a 4v swap.
