anyone use jb weld on there turbo setups???especially D series guys with homemade kits???how does it stand up?? i was thinking of using some of that too secure flange onto exhaust manifold, etc

 

hmm where the night crew at? Well I'll respond. One word, nope. The heat at the manifold is too hot and the jb weld can't handle it.

 

do it right or you'll be sorry - simple as that my friend

 

i used JB weld to patch up the holes in my intake manifold from my direct port instsll ,. works great

 

how about for the oil return line ??

 

how about for the oil return line ??

The oil will still make it through, i tried it like 5 times the i just took of the oil pan and just welded it.

 

I use the stuff all the time. Its very strong, and will hold up forever <u>IF</u> you properly prep it. JB weld can handle a lot of pressure, but its very brittle. Dont use it on any parts that may be subjected to shock. Its also only good up to a few hundred degrees, so its useless on any exhaust related fixes.

About using it on your oil pan, i can gaurantee that you didnt clean the pan first.
Once it dries JB weld is practically impervious to oil and most chemicals, BUT, while its still liquid it will actually absorb the oil. It will basically be super porous, and you'll have cronic leaking problems. the oil will altually drip through the jbweld. So basically, on oil pans just be sure to take the pan off the car first, and spray it down good with brake cleaner before you use it. Wirebrushing the paint off the pan wouldnt hurt either.

 

we used some jb on my friends bov flange once, it holds well, but i guess its not to hot there

 

do not use it for the oil return line. Trust me on this on, i had oil path from the store across the street to my old apt, because the oil return line fell off, because the temp was to high for the jb weld.

 

i used it on my radiator when the little mounting post on top snapped off. i sanded it down to the metal and jb welded it, it hasnt given me problems since. so i guess the top of the radiator isnt too hot for it.

 

how about on the bov flange on the charge pipe?

It will not work on oil no matter how well you clean , oil is ment to get in the tighest of clearences, blow off valve it does work. Its good stuff but it just dosent work on some stuff.

 

thnx for the responses guys..so basically jb weld is almost useless in a turbo install???what about if i wanted too use it too connect one or 2 of the charge pipes??

 

I guess it all depends on whether or not you know how to use it. i've seen plenty of oilpans fixed with jbweld over the years. I"ve seen AND fixed dozens of crankcases on dirbikes with the stuff.
All i can tell you is that if your not going to take the time to properly clean, prep, mix and let the stuff cure, then you shouldnt be using it.

 

for my oil return , my welder guy threaded it, screwed it in and welded form outside, there must have been a hair line leak, so i used that blue high temp silicone and it works good, oil return isnt under much pressure

 

I say no. My friend's friend did that with his Civic and he said it fell off a few days later.

I've used JB weld once on my car, and it was to put in a vaccuum nipple on the intake charge pipe for the Profec. If you prep and cure it correctly, it will stay hard as a rock.

 

my bov has been jb welded on for about 4 months

 

i'd say it'd be just fine on a bov, but i would not recommend it for the charge pipes. the reason being there is just too much stress if something shifts (we all know how well the pipes fit anyways) it would crack.
