Valve cover clearance

[blacknight80]

How much clearance do you guys have between the heater box and passenger valve cover. I swapped my ac box to a heat only hoping to gain a few inches and ended up with less. I have a set of stamped steels on it now and it touches the heat shield and I couldn't get aluminum back on. What might cause this lack of clearance?

Very little on my car with gn1's on it. That back valve cover bolt is loose on mine and I guess I'll have to jack that side of the engine up to tighten it. Blah.

The gn1s are taller than stock right? I'll throw a pic up tomorrow. I am hoping a trans mount might lift the rear up. I've done the driver side motor mount but maybe it's time to do the passenger side. I think a fresh motor mount might make it worse though.

lots of people ditch that heat shield for clearance.

I might have to do that. I figure stock vc should fit so there must be a reason why they aren't.

Motor mounts sagging??

I've got a new motor mount and trans mount coming. Hopefully it will sort it out

There is usually some wiggle room for the motor mounts. Sometimes you have to loosen the long bolt and shift the motor around. I have GN1S and the matching valve covers with HR mounts and I can remove the passenger valve cover with a little wrestling and it doesn't hit the shield.

The HVAC box on turbo cars is 1" shorter than all other production regals. It is possible that s heat only box is also larger near the valve cover area

For years, I honestly didn't even know that they came with them because all of the cars I've ever seen have had them removed, including mine when I bought it.

Years ago when the cars were new I guess many dealer techs would just.... fffff-peww, wing it right in the garbage!
one of those "extra" parts.

I might end up pitching it. I have been working on getting my dash back together from the heater swap so I haven't had a chance to replace the mounts. I thought the heat shield might be something us hot air guys would want to keep seeing the turbo sits right there.

Well I got the ps mount and the trans mount replaced. The ps mount fit like garbage as most replacements do from what I read on the forum. I fought with it for a couple hours before I got it to fit. The clearance is better but not where I would like to see it. I'm guessing the body bushings look similar to my motor anf trans monuts and that might be a further issue. If I pull my heat shield I don't think my valve cover will clear.

Update
I pulled the heat shield and there is a bit of clearance. I compared it to my wife's 83 na 3.8 and it's got acres more room than mine but it will do for now. I would never get a set of tall covers on it the way it sits.
