The bolt threads are also stuffed so like Room42 suggested I reckon that the previous owner has used bolts which are too long and has overtightened and stuffed them up. As the going says don't treat the symptoms fix the cause. I'll be getting the unit repaired professionally with new bolt stubs installed. Didn't really get an answer to whether or not intercoolers are manufactured with bolt holes through into the tanks or not but thanks for your help anyway.

They are not making any money. They are going to fix pro bono as I know the supervisor there. And they never said that sealant wouldn't work. Sealant can fix a multitude of problems. But my question still remains unanswered. Would ARC make an intercooler that requires you to seal the bolt holes as they are drilled through into the tank?

Problem is, I was sold an item that was supposedly it great condition and it is obviously not. The intercooler manufacturer where I have had it tested does not recommend using sealant in the bolt holes due to the possibility that it will come off inside the cooler and enter the engine. He has recommended drilling out the existing threads and welding in a new section of round bar which can be tapped properly. To me this sounds like the best and most professional way to rectify the problem. Back to my original question, There is no way an intercooler manufacturer would intentionally drill there mounting points through into the tank? I gather this is a correct statement.

It is definitely the bolt holes you can see they have been drilled through or retapped through into the tank when you look in the inlet and outlet. The guy who sold it to me keeps harping on about making sure I seal the bolts correctly when I install it. Question is was the ARC SMIC manufactured with the bolt holes drilled through into the tank? I doubt that any intercooler manufacture would design an intercooler this way.

I have just bought a 2nd hand ARC SMIC of off ebay for my R34 GTT. Before installing it I have have my mate who works at an intercooler manufacturer to check it out for me. He has set it up for a pressure test and it is leaking out all the bolt holes. I have tlked to the guy who sold it to me and he keeps trying to convince me that this is how it was produced. I find it extremenly hard to believe that a reputable company like arc would manufacture an intercooler which has bolt holes going into the tank and requires you to seal up bolts when you install. IIf anyone has had any experience with these coolers or ARC and can shed some light on this for me it would be much appreciated.

Does the dump pipe have the connection for the O2 sensor? Can't see in the photo.
