4.6 and 5.4 blocks are NOT the same blocks.

Yes, a V10 is basically a 5.4 with 2 more cylinders....but the V10 uses a balance shaft.

Believe it or not, there were also 2 versions of the 4.6....Romeo/Windsor which had a few different parts.

 

3.5L is NOT part of the MOD family.

 

3.0/3.5/3.7 = duratec v6
3.8/4.2 = essex (very similar to the windors, but don't actually share any parts, IIRC)
4.6/5.4/6.8 = modular (GTTDI CGI 5.0 version for the new mustang.. this is a bored 4.6)
5.8/6.2 will be the new BOSS series.. share a lot of design similarties with the modulars, but have larger bore spacing to allow for bigger cylinder bores.. the only current limitation to the modulars.)
2.0/2.3/2.5 are duratecs too
umm.. the 4.0 is a cologne engine.. based off the old 2.9
3.0 in the ranger is a vulcan

 

Good post.

I think I read where the new 3.5/3.7, even though pretty much based on the Duratech line, is now called the "Cyclone" series.

Main differences being soilid lifters (which still freaks me out BTW!!) Valve adjustment is supposedly not needed til 150,000 miles.......glad I only have a 39 month lease on my 3.5L powered MK-Z!!!

 

thats true, I forgot to mention that.

should also be noted that the 4 cylinder duratecs and the v6 duratec/cyclones don't share much of anything.

how's that mkz treating you dohc? haven't seen you around in a while. maybe because i haven't been in the competition forum, lol

 

It is scary to hear Ford is going back to solid lifters considering how difficult it is to get to the top end of many engines these days. On some of them you can't even tell where the spark plugs are located because they are hidden behind the fuel rails or the intake manifold or both. Can you imagine the cost to get your lifters adjusted(something that is normally reserved for race engines these days) at the local dealership? By the time you have 150K on the clock you are probably out of warranty. Maybe that's why they're saying it won't be needed until after you hit 150K miles. Most customers don't know the difference between a flat tappet, solid, hydraulic or roller lifters nor do the people selling these vehicles. The customer wouldn't know what questions to ask and probably wouldn't understand the answer even if the salesperson could explain it to them.

 

I think their main reason for doing it was so the engine wouldn't be any physically bigger than the d30 that it replaced/is replacing in some applications.

 

Most of the Toyotas have solid lifters in their trucks. (V6s, 4.7, etc) but I don't know about the 5.7. They are generally never adjusted and don't give any problems.

 

Except when the cams just plain snap in half

 

I didn't know about the solid lifters on the Toyota trucks. That's the kind of thing manufacturers make know readily. You have to dig for that kind of detailed information. How can a solid lift go 150K miles or in the case of the Toyota never need adjustment. At the drag strip the alcohol and fuel dragsters and funney cars have to adjust their lifters every 1/4th of a mile. In 150K miles that's 600,000 lifter adjustments.

 

I've actually read that because the cams now ride directly on the valves (no fingers/followers/rockers) that the motor is actually physically TALLER!!!

 

The Toyota and many others do like the motorcycles and don't actually have lifters. They use shims between the valves and camshafts to adjust the clearance. That makes very few moving parts and very little to wear. It works a lot like the valves on flat head lawn mowers. You never have to adjust them (which is done by grinding the end of the valve stem rather than using shims). My son-in-laws 95 Avalon has over a quarter of a million miles on it and there is absolutely no valve noise and it runs great. He hopes to drive it another 5 years.

 

What's funny is a few of us (me included) are using the wrong terminoloy............"solid lifter" doesn't apply to these DOHC motors.

Think it's "direct contact" or "bucket and shim".......sumpin' like that.

Now the OHC motors that use followers or rockers do have a hydraulic lifter or plunger at one end to take up lash. I think Honda has used the lifter on a few bikes as have most OHC car motors including ALL the Fords untill this latest "Cyclone" 3.5L.


Some Suzuki bike motors use rockers with a screw adjuster on their DOHC mills so the cam does not have to be removed for adjustment.

 

Thanx for axing:

IMHO, the motor transformed this chassis.

Always thought the Fusions biggest downfall was lack of power compared to the Toy and Honda. This motor would solve most of that.

I like the amenities(sp?) the Lincoln offers but it is lacking in a few details that kinda freak me out considering it's a $35,000 car.

Trunk doesn't open when unlatched. (even the lowly VW Jetta did that)

100 MPH+ the hood likes to dance a tad......I need to see if I can tighten the bump stops.

Top of the line THX monster stereo is............fair. That bums me the most because of all the reviews I read had the stereo being GREAT.

No rear A/C vents.......again, the VW Jetta had 'em.


NAV sytem is FANTASTIC!!!

Car is nice and quiet.

Comfortable ride.....not sporty, but not mushy.


Car did a bizarre thing on Thanksgiving day......snuck out of the house to get my wife her B-day present. Drove 20 miles to the strip, and on the way back the temp guage spiked and the car died on the freeway.

Ford roadside got me a flatbed to get it home and then had to call again to get it to the dealer Saturday.

Turns out the cap on the overflow tank is defective which allows all the coolant to escape over time.....the funny thing is, is it was dealer serviced aprox. 500 miles before the shut down......coinsidence(sp?)???

The good thing is the electronics saved the motor from a complete meltdown. The bad thing is I had to tell the wife where I was the last 3 hours..

All in all, when Ford blows 'em out on the low $300/39 month lease specials I think it's a great deal.....If I were spending $35K cash money, there are a few other cars I'd consider. (Infinity G37 comes to mind)
