I've ordered the manifold. I have some Q's regarding other components before I order them.
1. Pump o-ring and gasket or one and the same??
The water pump o-ring is part F1VY-8507-A, correct? Yes, I know a new one should come with a new pump, in which case I wouldn't need to worry about that particular part, but in any case...
The parts catalog shows this part to be not an o-ring but a cut gasket that goes between the pump housing flat and the block. However, as seen at 16:30 in the video in post #1, there is clearly no such gasket present when the original
pump is removed, indicating Ford didn't use the gasket on these cars.
As seen here
it comes back as "SEAL-4.0 I.D. O RIN", clearly indicating it is an o-ring. The price is exactly the same as the gasket, which would lead one to believe the o-ring is
the gasket and vice-versa, despite the pic: #3 doesn't look like an o-ring, now does it?
It's not just AutoNation, either. Fordparts.com catalog shows the same gasket (at 5x the AutoNation MSRP!
there a secondary gasket on these cars or not? If the factory didn't install these, why
does the official parts catalog show one (instead of an inner o-ring)? And for that matter, why
isn't the o-ring shown in the catalog, since it obviously does
go on the car (as seen in the video) and can obviously be ordered via unique part number (assuming the part number is not actually for the cut gasket)?
I don't want to yank the pump and [possibly] damage a [possibly existing] secondary gasket and then regret not having ordered a replacement ahead of time. And, I want to make sure I'm ordering the correct part(s) if I decide to reinstall the old pump instead of a new one (in which case I'll want a new o-ring at least
), and if I buy a new pump I'll [maybe/likely] want a new cut gasket on hand.
2. Thermostat o-ring.
I wonder what vehicle this
fits (check their I.D.).
Here we go again. Fordparts.com is showing an o-ring
, although they refer to it as a gasket, and
the exploded diagram shows a cut gasket for the housing instead of an o-ring.
At least the two suppliers' MSRP's agree on this part.
At 13:35 in the video, he mentions the o-ring and there's [again] clearly no housing gasket present.
So, is that the correct part number, despite AutoNation's I.D. spec and it being shown as a cut gasket instead of an o-ring in [portions of] the parts catalog(s)?
3. Fel-Pro vs. OEM PI intake gaskets.
Note I said I'll be using PI gaskets, not NPI ones, so this concerns only the PI versions, as those are the only ones I'm interested in.
Do the OEM ones have a metal or composite layer sandwiched in, making them superior and thus accounting for one
OEM being the price of the entire
Fel-Pro set, or is it just the usual price gouging because of it being OEM?
I don't want to cheap out and experience a leak anytime soon. BUT, if the Fel-Pro is just as reliable as OEM, then I don't mind spending half (or less), either.
Also, at 28:30 in the video he says there are two different replacement gaskets, but doesn't that only apply to [some] non-OEM ones? The OEM PI gasket can be used on either side, because the extra seal ring can be used on the front (t-stat) and back (heater nipple) by simply orienting them properly, so that one OEM gasket part number (YL3Z-9439-BA) is used on both sides, correct?
re: crackpipe mod
I'm not sure I'll have room at the back of the head to work, but I'll look into it. I'm certainly not about to hack on a brand new PI plastic intake, though, as here
I'm staying with stock t-stat rating. Not gonna do a cobra rad mod, either. I have other things to spend time and money on, so I'm a dud for now.
