Is there a head problem on 2000 Tritons?
Hey guys,I'm new over here, I usually hang out on the '48 to 60 board. I have a '56 F100, and it has an off brand engine in it(Chevy) anyway, I have an opportunity to buy a 2000 model E150 4.6 engine and trans with ALL the wiring and such. Everything complete to do the swap. My question is: Is there a problem with spark plug threads in the heads in these models? I thought I heard something about it on another board once? This engine has 79,000 miles on it and runs fine, and I can buy it for $600 with all accessories and wiring. I know it's alot of work in the change over, it's not my first day with that sort of stuff, but if they have problems, I'll just move on to another option. Thanks guys!!

The problem is with not enough threads on the heads for the sparkplugs. It can be caused by overtightening the plugs when they are replaced or it can be just one of those things when everything is fine and the plugs just shoots out the head. It's actually not too common, but if it happens to your truck it really sucks. Kind of like the OD switch that can catch on fire.......chances are you'll never have a problem.

There is a slight potential for spark plug blow out in the Triton engine family. If you consider the millions of these engines on the road to the number of actual failures, it is a very small percentageand what you see on boards like this are the people that have actually experienced the problem. I would say got for it. This opportunity to get your `56 F-100 back to a true blue oval truck should not be passed up. Good luck!

IIRC The E series is a year behind on the improved engines, so a '00 will be the NPI 215ish HP engine. Just a heads up if you were expecting 235hp out of it. All 2V modulars have the plug spiting problem so you aren't going to get away from it in stock form. Keep it maintained and keep them torqued properly and you will most likely be OK.

So am I to understand that the 00 would be a 2V? and WOULD have this potential for this problem?

Yes they are 2V. There was an updated head (PI) that improved horsepower about 20HP. Truxx is saying that the 2000 E150 is the older model with the lower HP. The "potential" problem is there, but I wouldn't worry about it. I don't think there is a machine without potential for it to break somthing.

Trunxx !!
Man, there's too many 9 sec 26-30lb puffers running around with 4 thread heads to not be all right!!!
alwas replace the plugs on a cold eng, torqued to 23 lb with thread release and you'll be good to go.
been there and still doing that.

2V were up to '04 in F150's '05 in SD and I believe Econolines. PI heads started in '99 with the 5.4L, late '99 early '00 with 4.6L's and add a year to that for Econolines. '03 F150's got 8 thread heads but some people have still spit them out but it seems to be very rare in them.

all 91-early 03 have 4 threads. No big deal if changed cold, anti-seize is used and properly torqued. Detonation is another factor that puts alot of pressure on the plug.
Yes, there are many 9 second Mustangs running the same heads with no problems as well as many Lightnings and supercharged Harley trucks out there with no problems.
