Hood clearance issues

[cavero]

Good body shops are so hard to find, but I'll see if I can find one in the area. Most around me only deal with insurance companies now. In fact, pretty much the only one in my area that would do the stripes is the one I used, but since then they've gone under new management and went to hell.

As far as alignment goes, if you look at where the hood meets the fenders, it lines up pretty well.

And even on the other side, it doesn't seem to as off where it meets the front:

Have any more shots from the back side? It looks like it may not be as well aligned there from the other pictures.

I'll try to get some more actual shots of the rear of the cowl tomorrow of Friday, but here's what I've got on hand:

Have you tried adjusting the little spinny things on the radiator cover? Sorry I have NO idea what they are called. That will help with it lining up with the grill/fenders but Im blown away with the rubbing/Rear fitment

What engine mounts do you have?

 

[cavero]

Yeah, the spinny things (bumpstops?) have been adjusted so the front of the hood lines up with the front of the fenders. I've shimmed the rear of the hood with washers at the hinge.


I have the Steeda urethane engine mounts

Have you lowered the motor?

 

[cavero]

GMitch, yeah I've lowered it 1/2", see below. I'm pretty sure I'm going to need to start looking at elbows for the PCV vent hose so its not resting on the coolant tank anymore. THEN I can start looking at dropping the engine even more (hell, I might not even need to if the intake is allowed to hang lower).

Chicago Connection (.us, not .com---that's a Pizza place) looks like a good place to start

The Steeda ones I have will go another 1/4" inch but after that I'd have to get a different set that would let me go down 1". The LH exhaust manifold is already pretty close to the steering shaft; I'm not sure if it would clear at 1" lowered

So as far as what I can do about that this, as you can see, the passenger side could be shimmed a little more, which may help some of the clearance issues on that corner. It's not going to solve the front intake plenum either.


Speaking of which, lowering the engine another 1/4" might not work that well either. Looking at this pic, you can see the PCV vent tube is resting on the coolant tank. I figure if I drop the engine, the intake plenum will just pivot off that vent tube and I'll keep hitting the hood.

My 2007 is lowered 3/4" and I am running long tube headers. You shouldn't have an issue lowering it another 1/4, or even maybe 1". As long as the motor isn't resting on anything you are not creating any problems. In fact lowering the motor improves the driveline angle.

probably going to relocate the PCV hose

The more I look at this, more I think I need to just relocate the PCV hose bung. I think Granatelli located it this far forward because of the nitrous option for the intake. Right by the throttle body, they left two bungs that could be drilled/tapped for NOS ports if the owner chose to go that route (see pic below). I think what I need to do relo the PCV fitting back there.

I don't think it'll be a big deal to have the PCV right next to the TB, looks like most CAI's do that anyway (see the C&L and Steeda CAIs below)

Not sure yet how I'd plug the hole from the old PCV fitting (I'd definitely chop off the stem). Really, I'd just get a new intake if the car hadn't been dyno tuned on this one.

^ Your pictures are massive but I can scroll side to side and get the idea.

Why not just get the 90 degree elbow fittings for the pcv line so it tucks in better instead of sticking way up in the air?

I assume yours is the first picture, make your line like the one in the second picture.

 

[cavero]

Yeah sorry about that, those were the only shots I could dig up that showed the PCV hose. 1st one is mine, middle one (red) is the C&L, bottom one is Steeda. I'm not sure the 90 degree fitting would solve my problem in that location. You can see what I mean up in post #28. I have a feeling that if you put in the elbow, it would still end up resting on the fitting.

 

[cavero]

Figured out how to make this work. Here's my fix.

1) cut off original PCV hose barb.
2) drill and tap to 1/4" NPT (already got the tap)
3) Fit this guy: (ordered from Summit racing)

4) clamp the hose in new location with these. Should help give a finished appearance, plus I've been suspecting my PCV hose may be contributing to my race tune tripping codes (P0172 & P0175)

Now, if the blue 45 deg fitting doesn't buy me any extra space, I can drill and tap the NOS bung (1 of the ones by the TB) and put the PCV hose there. For plugging the original hole, I found they make allen key NPT plugs:

granatelli? theres your problem

 

[cavero]

LOL, been a while since I've seen a Granatelli hater. I've had it since 2007, never have me any problems until I got the Shelby hood and lowered the engine. It pulls decent numbers on the dyno too, pretty comparable with C&L (although they're almost exactly the same shape...but that's a different thread).

 

[cavero]

Been busy. Cut off 2/3 of the PCV stem. Drilled, tapped (1/4" NPT):

NPT is supposed to be relatively self-sealing but I used Teflon tape

Tightened down

Here's my clearance on the inside of the intake. Pretty close if I do say so myself

 

[cavero]

hose ends give it a nice finished look

 

[cavero]

As for clearance, it's still contacting the coolant tank. But its only just touching it (not like before when it was really resting on it), and I've gotten another 3/4" of space now

And the side effect. Its kind of hard to see in this pic, but before not only was the corner of the tube sitting higher, but so was the end of the tube further up by the TB. Now that the tube is closer to its resting position, its definitely sitting lower:

Before:

Haven't taken it for a test drive yet, waiting for a good rain to wash all the salt off the roads after this polar votex crap is done. I might try to file back that wart where the old PCV was located a little more and drop the engine the last 1/4"

Test drive done last week. Definitely not completely clunk free, but a lot quieter now. I think I've got multiple sources and just elmininated one. And an extra plus: I have yet to trip a code with the race tune since. Wonder if I had a vacuum leak before (especially since there were no clamps on the PCV hose before).

Demoic, after the last test drive I shimmed the rear pass. side of the hood up a little more so not it lines up with the fender. I pushed down on the corner a couple times and felt/heard it still contacting the cowl after the shimming. But I also noticed that the cowl was sticking up just a little bit (like it wasn't totally flush against the windshield). I pushed it down flush and at least for the moment it stayed down. I'm sure it'll just pop back up again though. Haven't taken it for a 2nd test drive yet since we just got another round of snow and more salt down on the roads. Probably in about a week
