Changed spark plugs while engine was warm?

Hey, All
My truck hit 30,000 miles and was ready for the spark plugs to be changed. Since it was my first time I had a mechanic friend help. He changed them while the engine was still warm. What are the odds that damage was done? I've been worried about my engine ever since. I hoping someone has some good news to help ease my mind. How can I tell if any damage was done? Thanks everyone!

 

dosent matter, maybe torque specs could be off.. I wouldn't worry about it. I prefer to do my plugs with a cold engine, just so I don't burn the shit out of myself

 

I think you're paranoid. It's Georgia in the summer even when it's 90* out the engine will be warmer than ambient temp.

 

Okay Thanks

 

If the plugs came out and went back in, your golden. I do it cold cuz I hate pain.

 

Always do it hot on customer vehicles. Prevents risk of seized spark plugs pulling the threads from the head. Yes, it is hot to the touch, but I am used to it, and have special tools to prevent burning myself. I can do a set on a V6 Tacoma in under 10 minutes.

 

Special tools like a socket set...

 

It's too bad this is the shit dealer technicians have to do to make a decent living. Is it possible to swap plugs in 10min? Sure. Can you check and adjust 6 plug gaps, get the right amount of anti-seize evenly on the threads, blow out the holes after removing the coil packs but before taking out the old plugs, and take enough time to be careful with a customer's vehicle in 10 min?

 

I thought anti-seize was a no-no?

 

This is why I do the work myself. The other part of that is, you pay a technician to do a particular task, like change the oil or plugs, etc. They do just that and may not take the time to notice something else wrong with the vehicle like maybe a differential seal starting to develop a slow leak.

 

^^^exactly. Most of these people are good techs, but to feed the family they have to ram 'em in and ram 'em out.

It's shitty.

 

If you don't want to take my word for it, take his:

Amen to that!!

 

I actually prefer second and third degree burns from engine work, that's while you'll often find me running my truck for 30-45 minutes, then changing the oil...making a point to purposefully dip hands in the scalding hot oil. It's really just a technique I've adopted over the years, that, and enhanced pain compliance.

 

Really?? You change oil when the engine is still hot because that's when all the contaminants are suspended in the oil. Otherwise they can settle and won't flush out with the oil.

Also, if you're a competent mechanic, you shouldn't have your hands in the scalding hot oil anyways...

 

And hands!

 

It's amazing what the manufacturers publish.

I mean that is NGK but I replaced all with NGK and not Densos so... YMMV.

(assuming everyone knows we have 3 NGK 3 Denso)

 

It was sarcasm. It was either lost with you or I did a poor job conveying it, either way my bad.

 

Oh... my bad

 

I have read that many times over as I am due for a change. However, I have seen other threads where people say to stay away from the anti-seize. Some said none at all and someone said dielectric grease.

Not really that mechanically educated to have an opinion as this would be my first plug change.
