Been off of here for about six years. Sold my trucks and was in a Mustang phase for a while. Then decided to drive a responsible new Accord for several years. Now I'm over it and ordered me a new Magnetic F150 Screw 4x4 Special Edition Fx4 etc on the 11th. Had to go with the second generation 3.5 EB and the new 10R80 transmission. Im still a Ford dealer tech so the EB has kinda grown on me over the years. Even with all the issues I've seen with them. So anyway, hello all, I'll be on here browsing and chatting in the foreseen future!

 

welcome back

 

Welcome back, so I have to ask since you are a Ford Tech do you see that many more issues with todays EB than with the NA engines?

cause us turbo delete guys are just cruising while the turbo guys are fast and furious. turbos they do good on gas engines but better for diesels. (heat)

them 3.5 hair dryer engines are bad ***. and have been around. they just have too many mor working parts to fail.

jmo.

 

Definitely. The 3.5 has its share of issues. Lots more going on under the hood than the 5.0. Lots of misfire issues. Boost pressure and map1/map2 sync issues. Water pumps are starting to go regularly now. Fuel in oil contamination issues. And the ones that drive me nuts. People complaining about intake resonance noise when they own a twin turbo vehicle. There are some other issues but that is the most common ones. I've seen about four complete failures. One from the factory. The rest around 55-80k miles. So they are pretty reliable from a general stand point. I've only seen one 2.7 failure at this point and that was due to an oil pump failure with about 4K on it. Gears just ground into the oil pump housing. Seen lots of auto/start stop issues. Usually the external transmission pump for that system. All have been very low miles. The 5.0 coyote. Tough as nails. Have seen three failures. One was a mustang that he ran low on oil and blew it to pieces. Ford still covered it. SMH!! The other two were one with 55k that the #5 injector stuck and burned the rings/bore up for that cylinder causing misfire code and low compression. The other was the infamous ticking that occurs in the bottom end at idle. Which is actually caused by main bearing wear. I've seen several of these. Only one I have actually fixed. The other two were not under warranty and I suspect they sold the trucks. Exact same noise though in all three. So for as long as these have been out(minus the 2.7) that is very few absolute failures in my opinion. Trust me....in the 1990's I spent most of my days replacing or repairing engines. These days....about 4-5 days a month. Reliability has come a long way. I suspect due to oil coming a long way....

 

Funny all the 5.0 failures I've seen were grenaded oil pumps. Not really a problem at truck rpm unless you supercharge them.

 

So main bearing wear is the cause of the knock? Interesting. I've read that out of round cylinders were the cause, but I don't know how they came to that conclusion unless they tore the engine apart and measured the bores.

I traded a 2013 that knocked at idle when up to temp. It had 17k miles on it when I traded it. I noticed the knock at probably 10k. I wonder if it had worn main bearings? Crappy bearings if it did lol.

 

IVe installed a few sets of the billet oil pump gears. But I've never actually seen a failure of them. That's aftermarket land....that they see those I suspect. There is a highly popular mustang shop here. They have told me it's a common issue on power adder coyote's. The water pumps are starting to fail though as well. Which I guarantee is due to the serious belt tension on that FEAD. I have one waiting for me Monday to do...third one in a month.

 

Like I said I've only torn one down to repair for that noise. It had bearing material in the pan and the mains were severely worn. It may have had a out of round bore. I honestly don't know. With crank/ bearing/ rotating concerns we just replace them no matter if it's base/ power train/ or Esp warranty.

 

Just got my 16 2.7 back from the shop for the external pump failure. Still having the 5 to 4 hard downshifts and pretty sure my transmission is shot. 18k on it.

Welcome back by the way
