Gen 2 SCAB makeover…totally not ripping off Geoff’s 2.5 build!

Only had a couple hours to work on the motor today, but made good progress…



Realized I got way ahead of myself and pulled the cams with the cam phasers still attached, LoL, so left one head on so I can reinstall them and put in the cam locks to remove the phasers mañana or Friday.

A lot going on, so pics are a bit out of sequence…

Motor mounts were actually in pretty good shape, but will put new ones in regardless:





Even though I’m pulling everything, I ran the motor through a few rotations to confirm the timing, etc. and to test fit the cam locks:



…no issues or surprises getting the timing chains, guides, tensioners, etc off:





And only had one bolt head strip when removing the cams; gonna use all new ones when I get the heads back from Headgames anyway:



The cam followers and lifters look to be in good shape too, but these will all be replaced by Gen3/Coyote parts:



Will swing by Ford and grab one to confirm they really do fit before ordering 24 of each!

Nothing unusual getting the RH head off, except that cheap harbor freight engine stand kept wanting to spin when I was trying to break the bolts free, LoL. Will have someone come over to hold the motor or maybe strap the stand to The lift post or something for the other head!

Combustion chambers on this bank look pretty normal for a 115K motor to me:

The cylinder walls looks OK, but holy crap there was a lot of debris/carbon on the pistons! A lot of it clearly fell in there when I removed the head, but wow!



And WTF is this little plastic tube I found when I pulled off the head gasket?



There’s a groove machined into the cylinder liner that it sits in, so I think it’s supposed to be there, but what is that thing?

Only part that gave me trouble today was one of the bolts holding on the oil filter housing/heat exchanger unit. Again, I want to nut punch the Ford engineer who though placing a bolt here was a good idea!



I had to tap that wrench down into that gap with a punch and hammer, then work it oit slowly as I loosened the bolt what felt like 1 degree at a time!

Maddening.

At any rate, another big pile of parts from tonight’s efforts; exploded onto the bench waiting to be bagged, labeled and put into bins…



More to follow.

@full-race geoff or anyone who has done work on these heads: How hard is it to pull the spark plug guide tubes?

I tried tapping on them with a rubber mallet and then just pulling/twisting on them by hand, but they’re not budging. I assume they need to be removed in order for Headgames to do their pocket port and valve job, but don’t want to mess something up if they aren’t supposed to be removed.

Will call Headgames mañana to ask too… They never answered my question about whether or not their “Raptor valves” are the SI valves. I assume they are, but want to confirm before the work is done.
