CECAA850 Posted May 6, 2016 Share Posted May 6, 2016 Imagine a dump truck dumping rocks onto a sheet of tin roofing, or lots of rocks in a tin can being shaken violently in every direction. That could certainly be the description of pre-ignition. If it goes away instantly when you take your foot off the throttle, that's probably it. 1 Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted May 6, 2016 Share Posted May 6, 2016 BTW, the reason your mechanic didn't want to do a tune up is because the spark plugs almost always break when removing. You need a special repair kit to extract them and even then, they're a PITA. Absolute worst case scenario is pulling the heads to repair them but someone who's done a few can normally extract them without pulling the heads. It's extremely common for them to come apart even if the tech does everything right. 2 Quote Link to comment Share on other sites More sharing options...

BTW, high octane gas didn't help it much if any. Edited May 6, 2016 by MetropolisLakeOutfitters Quote Link to comment Share on other sites More sharing options...

So I best not attempt it myself then? I have an appointment on Wednesday at the dealership, they are looking into a re-flash. I guess I better book a tune-up as well? Have an appointment in an hour for an exhaust shop to look at the cats. I guess my concern about all these different places is the old saying, if the only tool you have is a hammer, all your problems tend to look like nails. 1 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted May 6, 2016 Share Posted May 6, 2016 I wouldn't swap plugs at home on one of those motors without access to the special spark plug extractor kit or a tow truck. Quote Link to comment Share on other sites More sharing options...

jason str Posted May 6, 2016 Share Posted May 6, 2016 I always apply a liberal amount of anti seize on new spark plug threads in aluminum heads. Highly doubt most technicians even bother using it, the above picture shows what is likely to happen without it. 1 Quote Link to comment Share on other sites More sharing options...

Highly doubt most technicians even bother using it, the above picture shows what is likely to happen without it. The problem with this design isn't the threads you can see that they're fine. There's a long end on the plug that sticks down into a chamber. The chamber fills up with carbon and basically bonds itself to the plug. Maybe never seize would help? I don't know. This is a chamber/plug design that didn't really pan out. Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted May 6, 2016 Share Posted May 6, 2016 The other issue with the plugs is that the manufacturer doesn't put anything on the plugs from the factory and this normally happens the first time the plugs are removed. Quote Link to comment Share on other sites More sharing options...

Rubber mallet method works very well in locating a rattle as the whack does not resonate through the exhaust like a harder surface would. 1 Quote Link to comment Share on other sites More sharing options...

I was having a computer issue in a client's office a few years ago. The IT Department sent a female tech to handle it. She was FOTB from Russia. Her fix was to open the case and start removing cards, throwing switches. When she was done she announced it was 'fixed' and left. Wouldn't even turn on after her repair. The next tech they sent removed that pc and replaced it. Quote Link to comment Share on other sites More sharing options...
