Cracked Air Filter Housing

[365gtb4]

On my 1990 ZR-1 the air filter housing has a crack along the molding seam.
Any ideas on repair or where to buy a new one?

Thanks in advance.

The majority have a similar situation and you could likely have it "plastic welded" to offer the maximum strength for a repair. I don't believe I'd attempt any epoxy type repair. Plastic welded by a competent shop should do well and most collision shops should be able to help you. It could be an interesting project for a vocational body repair class if there's any in your area.

I have had good luck fixing plastic cracks and breaks with JB Kwik Weld. May not be the high dollar or perfect solution - but if you aren't concerned with having the stuff on the outside it will work. It is black - but you do need to get it on there about 1/8" thick or so. I have also used blue painters tape to tape off the area I want to put the stuff to make it neater. My plastic radiator tank on my DD cracked about 3 months ago and this stuff fixed that. In fact my skimmer plate for my garden pond broke where the spring loaded bar goes into the skimmer - and I have it in the garage with the JB drying on it right now. Will be good as new tomorrow...

If my memory serves me correctly black the plastic air filter assembly is the same as on the LT1 & LT4

Yeah unfortunately it happens not rely a big deal but you could try the plastic weld. As flew a Replacement I believe the Same part was used in every 91 and up car.

Harbor Freight or Menards get a plastic weld kit and go to town! I think they are $12 at Menards(that's the hot iron welder)...was at a body shop and saw a demo using a Harbor Freight welder(using 1200 degree air gun and an Iron)...fixed a large bumper tear....we tried to rip it after and could not do it. pretty amazing stuff.

just like with welding groove the crack and fill

This is probably good enough for what you need to do

Welcome onto the boards there.

Is this going to be a show car?

It shouldn't be too hard to find another housing at a used parts place that specializes in Vettes. Why screw around trying to fix it?

[LGAFF]

I have several, maybe we could trade and I could use yours for my Frankenstein intake project

THANKS everyone.
The car is a bone stock 90, black with grey interior and I plan to keep it that way.
I will try the welding plastic method. We just did a plenum pull with new injectors and are now replacing the hides and seat foam after rebuilding the seat mechanisms. Next is the radio capacitors and air conditioning.
We have two projects here. We are putting the 90 back in shape and also building a 66 coupe with an LT-5 engine. The 66 car will be an automatic designed for comfortable cruising.

Black urethane made by 3M and used to install windshields will work and be there forever. Be sure not to get it on your skin. You`ll have to wear it off.

That would called BUTYL. Good product for what you need. Fusor makes some excellent adhesives as well.

Actually what I think Richard Till is referring to is 3M 5200 adhesive. That's best stuff I've ever worked with, it's a moisture cure cross linking urethane adhesive, comes in black and white. We use all the time in boat building. It's a permanent binder. It's slightly flexible and insoluble in most solvents and water proof.

If the welding doesn't work I will use the 5200.

Try getting a hold of Shawn at Corvettenutz. I know he has those intakes- all the LT1 styles are the same and I know he parted out a couple of low mileage cars too (both ZR-1's and LT1's).

The reason I mention it is because he is in lake Elsinore so that's not too far to make the drive if the price is good.

Looks new to me, I just paid 195 for a L98 housing assembly. :cheers:
