Replaced Voodoo Engine

Hmmm... if they were serviced by that dealer (oil changes) I would be weary of taking mine there.

 

As the 2018 5.0 now uses the same PTWA cylinder coating as the GT350 5.2, we may see more of these failures.

Ford engineers say that the plasma transfer wire arc coating is super durable and that the cross hatching is still visible after 200,000 miles....so I doubt the issue is there.

 

I understand why, but it is a shame ford isn't more forthcoming about this issue. I don't know if I have two of the greatest mustangs ever built or ticking time bombs.

 

I'd be shocked if the issue was with the cylinder coatings. It wouldn't be the first time that Ford had out of round cylinder issues though. The cylinder lining has been used by Nissan under Fords patent for over a decade now and it's a non-issue there and they typically run much higher cylinder pressures.

 

Well said! I sometimes wonder the same thing about my GT350.

 

I came from a C6Z with the LS7. I’m glad to see I can’t escape catastrophic imagine failures. LOL

 

Ha! I too came from a LS7 (Z/28) to the Voodoo. Oh well.....

 

my dealer has also replaced 2 engines, 1 for excessive oil consumption and the other had 400 miles and suddenly lost oil pressure and shut off....they thought OPG failure, i saw the inside of the oil filter and it was full of bearing debris
mine at just over 1000 now is amazing, but always watching the oil pressure

 

the saving grace is ford does not waste much time replacing the long block(as i just found out). so i guess worrying about it won't do much good as you'll just get a new one anyway:cheers:

 

Well said. Maintain it properly, watch your oil and pressure and then drive it like it was made to be driven. You cant control much after that so, no use worrying about something that may or may never happen.

 

OP, are you trying to get a count of how many members had engines replaced or just different reasons why? Or both?

My 16 tech had an engine replaced due to excessive oil usage. My 17 has nearly 8k on it and has been fine.

 

i was one of the ones with engine replaced

 

I do think it would be valuable information to try and get a total count (at least of forum members and other sources) of blown engines. things seem to get blown out of proportion when it comes to bad things happening but it does seem there are lot of these occurrences.

 

2300 miles, tech assumed it was a main bearing, but Ford told them not to split the case...Had a thread about it to document it, but some troll decided to piss all over it and got it closed.

 

My car had the engine replaced before I bought it. I bought it with 2700 miles.

 

Count me in. 2018 with about 1900 mi on it failed 2.5 months into ownership.
Spun main bearing and rod through the block but Ford never told what actually failed that contributed to it seizing. 52 days to repair due to backordered parts.

 

Worth Doing

Does anyone here have a realistic estimate of the percentage of Shelby owners that are members here? Say, 5 or 10 percent of total units sold? If a reasonable and conservative percentage estimate could be derived,
Putting up a poll could be of some value.

My .02. BTW, I also had an LS7 Vette, and near as I could tell based on extensive conversations within the community, including tuners, there
Was definitely a problem with at least 5-7 percent of these engines
Dropping valves... Of course, GM never admittedly to anything. In my case,
I had new 5 axis CNC Brodix LS7 style heads done by one of the best
Shops in the country - the one that KATECH goes to.

 

I suppose a percentage in this forum population with blown engines would be a good representation ballpark, if you extrapolate out to the number of units sold.

 

Miss the z28?

I've seen some pop up in the low 40s.
