Well, I just finished installing the new HPS intake, TF elbow & 75mm TB... fired right up and wow, what a difference in idle quality. Overall just a whole lot smoother than before. I took it for a little burn around the neighborhood and the new intake definately suits this combo better than the PI intake with adapter plates. Now it's time to throw the WB back on there and tweak in the MAF transfer function for the new combo. I plan to head back to the dyno soon for some "after" numbers.

where did you guys, 4v guys to be specific, get your gasket kits and how much did you pay for them? ive been lookin all over and the only place that carries a 4v kit is mmr and they are $399. im sorry but im not payin that much for gaskets haha. any ideas?

Something easy to try, this is how I found my miss... Pulling wires on coil packs didn't seem to make any difference in the idle so I was chasing vacuum leaks. Then went back to the coils again... Put the e-brake on, put a block in front of a tire, and put in in drive to load the engine. Then start pulling coil connectors one at a time and listen carefully for a change in the idle. I had 7 that made it very slightly rougher and one with no change, i.e. one bad coil pack. I then swapped it with the cylinder next door and repeated to rule out the injector or wiring, got the same result on the new cylinder so that coil pack will get replaced. Maybe you've already done this, if so disregard, but otherwise its an easy way to check them....

I've *sorta* figured out my oil consumption that I've mentioned in past posts.... I put an oil separator on my pcv lines and after ~20 miles of driving I've got around 1/4" of oil in the bottom of the cup... Good to know my valve guides aren't bad like I thought but holy crap thats a lot of oil whipped up into the air. Anybody have a known cause for this other than just ohc engines have more motion under the valve covers??
This REALLY makes me wonder how much oil is puddled in my intake plenum......gonna have to keep looking for an aluminum PI intake. If anyone has one or sees one for sale would much appreciate the heads up....

Note to all: I had really really bad time with Fel-Pro's valve cover gaskets. They were a mega bitch to get to not leak. Once they're on they're fine but what a PITA.

No, I don't think it would make much difference, if you need to know unhook the x for a dyno run sometime.
I would have gladly paid you some for them, but ordered off ebay yesterday. Thanks anyway.
I know an ohc engine should have more of an issue, just can't quantify how much is "normal" and how much might point to some other issue.... Might be possible to install a fine mesh baffle under the hole in the valve cover, don't think I'll go that far just yet though, I'll install a 2nd separator inline with the other first if I think I'm not getting enough out of the air.
I have a bunch of them laying around. Want me to send you 3-4?
the spinning cam lobes and the high level of vacuum present are the biggest contributors that I can see. The low pressure (vacuum) turns what already has a smallish droplet size into a very small droplet that's more stable in traversing the intake system until it smacks a wall and joins with the last droplet that did so. Reducing engine vacuum would help, so would a windage tray of sorts enclosing the cam. Neither is practical in my view.

if in good shape what gaskets can be reused? also can i reuse my headstuds? i dont remember if they can be on these engines bc i thought once you torque em down they stretch and cant be used again unless you over torque them the next time which might cause problems

HPS intake question
Hey everybody, I have a question. I am putting my engine together and I have my HPS intake on. I put the 4.6 alternator on and tried to use the stock upper bracket fromn the 4.6 PI intake. Well, it doesn't fit. What have the other HPS users used for the upper alternator bracket?? Also, I saw I think JScottGT had an interference with the HPS intake bottom and a rib on the block in the valley. I had to grind down the rib on the block and grind off the lettering on the bottom of the intake to make it fit. This was when using Ford intake gaskets. Beware HPS intake users.

DO NOT reuse stock head bolts. They're TTY. I'd buy some ARP (and did) studs.

I think there's a variance year to year in how tall those ribs are. It seems like a 50/50 shot. It's not that big a deal though to take a grinder to it and knock 3mm down.

thanks r3d! you've been a big help and always there to answer questions. im gonna be askin alot more soon bc i finally got all my money together and am gonna be ordering one of the shortblocks from kk and get my intake sent off to be widened and finally get this thing under way ha. btw i was out messin with the car earlier and i dont think ill need k member spacer since im using my stock intake. right now i have about three inches of clearance so i dont think i need them unless you guys think otherwise if its not necessarily a height clearance issue rather than on the side to clear the master cylinder?
#6346
Just kidding... it was between $200-$220.

4"... and it still rubs. I need some k-member spacers, upto 1" i think. the guys that made my k-members dont make them, and told me i was dumb for wanting them, they said i should have told them so they could lower where the engine sits, ... i probably should have done that but then again it already sits so low. It would have made getting headers in there easier.

DO NOT REUSE THE FACTORY HEADSTUDS.
#6353
Thanks, I asked HPS to do it drill and tap it. But he threw in a port match so I wont worry about it.
What kind of gasket does the plenum cover have on it?
Edit: I just looked at it, RTV.

The sensor is a 3/8 NPT thread. I drilled & tapped mine at the back of the intake so I could install my autometer gauge sender.

if you're talking about the common plenum (the big empty box in the bottom) then RTV works great and is the intended method. If you're talking about the upper plenum mating surface to the intake, then a either fibre gasket or a light schmear of RTV will work. Most aftermarket plenums come with the fibre gasket. I had the shop use RTV on mine since it's damn near free.

edit: this is only the prototype drawing vs a picture but the groove matches the stock intake so the gasket can be moved over....
