can I epoxy an cracked VC?

Rich- · 05-31-2015, 09:57 PM

temporarily?

I plan on ordering a new one, but just to get me by for a while?

today did all 6 new injectors and calve cover gasket,
I cleaned up the VC and got it all together, (it went amazingly well, cant believe the dealer want 1K to do just the valve cover job) I looked the VC over and all looked good, got it all put back together and fired it up and noticed a little oil from a crack I didn't see when I was looking it over as I was looking in other areas I guess.. this is right behind the oil fill cap

think I can get by with some epoxy for a few weeks until I get a chance to have a day to tear into it again?
product recommendations ?

Yea I think you could . Just make sure you check on it everyday to make sure it hasn't started back leaking .

If anything would work it would be JB weld high heat....I think it would work well if properly cleaned and prepped surface.....I remember years ago I had a crack that I sealed with regular JB weld that held for years and also filled a hole in the crank cover on my old Gs 750 e motor bike.

yeah, I had a coworker that used an epoxy on his cracked radiator, and it was still good after 5 years. ill swing by the store and see what I can find

Make sure to use a good 2 part epoxy and give it the needed time to cure. Should be strong enough to hold up for a while.

+1 - whatever you use needs high heat-tolerance and oil resistance. Make sure you give it ample time to cure before taking the car out again.

If it's a short term solution then yes, just remember temporary.

YES it is just for a short term, I plan on replacing it, but just don't see time anytime in the next few weeks to tear into it.

thanks guys.

I haven't seen it yet.

If you absolutely have to, to get you by, I'd use (as others recommended) JB Weld high heat. I used JB Weld on the brass vacuum fitting I installed in place of the POS flimsy one where the BOV/DV connects to the manifold and its rock solid.

Bought the JB from Lowes.

I picked up some JB weld from autozone says its up to 550*
I plan on scuffing up the area good, and letting it cure for a day or 2 before driving.

Hope it works, just don't let it drag on too long before getting that VC replaced.

It will hold up for sure. My E36 had a 10 time worse crack on mine. The previous owner used some ghetto epoxy and leaked oil. I found it cleaned it up and JB Welded it. I sanded it after and surprisingly almost same color as my VC.

Trust me JB Works wonders!
