I have a 1986 Trans am 305 TPI, I was in the process of giving it a full tune up (just got the car no idea how the previous owner trated it) so I started the spark plugs managed to get two switched with fairly little difficulty but now the third plug back on the drivers side is STUCK, and I mean stuck to the point where it will not budge at all. I ended up breaking the stalk off and am getting irriated with the damn thing. Any tips or advice to try would be helpful. Thanks in advance.

Not quite sure how its stuck... Are you using a spark plug socket? I picked up those flexible ones from harbor freight, and they work fine.

Is PB Blaster that effective? The only heat I really have access to is a lighter.

You will need a Propane torch at the very least.

Home depot for like $20. And yeah pb blaster works good. Remember though if you blast it full of oil and then use the torch you might see a little more smoke than you expected. Best to lick the plug with the tip of flame on low and burn oil off first. Keep a wet rag handy to slap over fire if it gets a little frightening.

pb blaster is that good

best to heat first , the spray with the blaster, it will smoke but the heat will pull the penetrant into the threads just like when you solder cooper pipe.

Thanks for the tips, I picked up some pb blaster and have been soaking the plugs. I have my brother coming down in a couple of days to give me a hand with finishing the job up. If all else fails bringing it to a shop and they can deal with it.

why dont u just put a long pipe around your socket wrench for more torque/leverage?

PB blaster and a breaker bar and I was able to get the plugs changed, thanks for the tips and advice from everyone

put a lil dab of anti-seize on the threads of your new plugs.
