In what areas did the factory seam seal the engine bay?

On my dart there was a blob of seam sealer at ea. corner where the cowl meets the fender aprons.

I stripped my engine compartment down to bare steel and other than those two spots at the top of the cowl I can't think of any other place that has any sealer.

I'm not real sure, but I think they might have put sealer between the top of the fenders where they bolt to the top of the inner fenders. Someone else might be able to varify this.

I just remembered that there's a Mopar show I can go to next Saturday. I'll go ahead and check out the engine bays there.

The fenders had a sealer between the tops and inner fenders. Unless you see an original car or one redone correctly, most times they won't have it. I know on my own cars I skipped using it as I never drove them in the rain anyways. Some cars were pretty messy from the factory, others you don't see it.

Seam sealer at horizontal fender joint.

Seam sealer on underside of fender at horizontal joint. This sealer is tan and still soft.

Welded seam at firewall to cowl joint had sealer oozing out. This sealer is painted. Also there is a black blob on this seam directly above the left side of the master cylinder put there after the body was painted. There is an identical unpainted blob on the passenger side also. Bonus: factory made an orange paint daub above the master cylinder.

Sorry, I inspected the dark blobs closely and found they actually are painted - the paint just didn't adhere to the sealer well, but the paint is there. The firewall-to-cowl joint had sealer placed on the joint, then it was clamped and spot welded, causing sealer to ooze out. More photos later.

Four blobs across the cowl seam. There are also two more in the front corners of the engine compartment where the inner fenders meet the radiator yoke to cover small holes in those joints.

Intended blob at the passenger side, along with an unintended extra. Note that the hole in the corner isn't totally covered.

On my 68, the welded seam had sealant in between also...however, I don't think it was seam sealer. It looks to be what our paint shops here call "hood Flutter". It is more foam like and has air holes inside when you break it apart. The stuff I bought for in between the hood skin and inner structure was a 2 part mixture in a gun and when applied, it expands and sets up pretty quickly.

this is the stuff I will use when I replace the upper/lower cowl area when welding them together.

Think the guy that did your Dart was on his second day while one of my old Demon's must have been his first. On the Pass. side cowl to fender area of this one Demon there was a giant blob of sealer, almost like the sealer gun got away from this guy and stuck in that blob were two nuts for the fender stud in the door jamb. All this mess was painted yellow with the rest of the car.

I found six (6) places where seam sealer was applied on my StL built 69 RR. I will post a picture of one side.
