Oil Pan Bolts (reuse most of the OE bolts, but need 2 more of the ones that are reused to replace the bolts at the back of the pan due to the flange thickness on the aluminum pan vs. the plastic pan): https://www.fordpartsgiant.com/parts/ford-bolt_-w712943-s437.html

Oil Pan Sealant: Here’s the genuine Ford stuff, but any thoughts re: using plain old RTV sealant? https://www.amazon.com/dp/B001H1KGVE/?tag=fordraptorforum-20

Engine Shampoo to remove brake cleaner residue, and everything else before applying the RTV sealant: https://www.amazon.com/dp/B000NU3Q12/?tag=fordraptorforum-20

Metal Etching Wipes: Friggin’ expensive, and once opened the whole container is pretty much shot. Looking for other options here:

@full-race geoff I can’t seem to find ARP main cap bolts or studs for the 3.5 ecoboost. Any tips?

Found these from Livernois though: https://www.livernoismotorsports.co...ts-2015-2016-3-5l-ford-ecoboost-main-stud-kit

Congratulation and good luck, we will follow you !

There are cast aluminum valve covers available for the Gen 1 3.5L but they are machined improperly and leak worse than stock. Ford actually has a lot going on with these parts an I think its best to replace with OEM.

Dang…yeah, not digging these plastic valve covers at all, but function > form in this case for sure

Did you happen to ID where the crack is exactly?

I honestly can’t find any cracks, but there was oil pooled on the top of the LH (driver’s side) valve covers at the front…on both left and right sides of the LH cover. Maybe just a bad gasket?

Will look closer today with a magnifying glass.

Will post a real update tonite, but gotta run out to get some larger allen head bits for two of the block plugs…and take my wife out to dinner, LoL.

Teaser pic on today’s progress:

I'm going to be real disappointed if this doesn't end up painted old Ford blue engine color.

I'm going to be real disappointed if this doesn't end up painted old Ford blue engine color.

I hadn’t actually considered that, but damn fine idea! Won’t be able to see it under all the turbo and coolant plumbing these motors wear, but I’ll know it’s there.

Valve covers too.

 

[91Eunos]

Speaking of the valve covers, I looked closely, but cant see any cracks whatsoever. These are the spots where I had oil pooling on the LH cover:



And here:



Guess I could just try new gaskets, but if I’m gonna go to the effort to clean and paint ‘em, I think I’ll just start with new.

Clearly didn’t get around to cleaning off the bench yesterday…spent the entire day looking at various cars to replace her wrecked X5, and then went out to meet our son and his wife for dinner downtown.

Started off today with a nice breakfast sammich brought out to the shop by my lovely wife:



And then proceeded to finish tearing down the block. No issues on the outer cap bolts and that sub-plate/secondary girdle (whatever it’s called), but I couldn’t get a socket over the main cap bolts for the #4 bearing at the back.

Thought I would try a flare nut wrench from my brake tools:



But wound up just using a smaller/thinner-walled 3/8” drive socket with an adapter to fit the breaker bar vs. the 1/2” drive socket. No issues other than that.

Remembered the side bolts for the main caps, just after I started tapping the first one with a rubber mallet and couldn’t figure out why it wasn’t moving! LoL



They all looked good except for #2:



The rod bottoms all looked about the same…some kind of pitting, even though they felt smooth to the touch:



…but the actual bottom half of the rod bearings all looked pretty good for this mileage; again, they all looked about the same:



However, when I got the pistons and rods out, there was a lot more wear on #3 upper rod bearing than the rest… probably not long before it would have spun.



Here’s all 6 laid out:

Once I had the pistons and rods out, it was time to hook the block back up to the hoist, so I could access the bolts holding on the rear main seal and rear plate before I pulled the crank:





…and a few small bolts later:
