Oil cooler housing gaskets

[Patrolos]

Yesterday I was changing my oil pressure switch and cracked my "oil Cooler housing" (cast alloy). I didn't over tighten the switch but it cracked from the thread up along the housing for about 20mm. Needless to say, it now leaks badly.
Took it to the mechanic who was able to find one at the wreckers. They told him it's very common on the TD42. So be careful when replacing your switch.
Problem now it that it's going to take at least 2 weeks to get a genuine gasket kit prom customs to the Nissan dealers then to my mechanic. We were able to plug the thread and pack it with "Cold Weld" (rated at 3000psi). I'm picking it up this morning and hope it's going to hold.
Do you think we can get a gasket from any one else other than Nissan? I don’t trust driving around for the next 2-3 weeks with bog keeping my oil in.

If your mechanic is any good at all he should just make a gasket. Five minute job with some gasket paper and a small ball pein hammer. If he cant do this I suggest finding a mechanic who can.

No offence mate but did you insist on a genuine gasket ?

or is your mechanic just as dump as an ox ?

there is a million silicone base products on the market ,that will work better than the original gasket ever would have

sika flex would have at least 5 and other brands as well all so come in high temp applications designed to seal things like sumps and tappet covers etc. ;)

He insisted. Apparently the kit has 2 gaskets and 2 "O" rings.

Each to is own tassie patrol but a genuine gasket is ALWAYS preferable to a gasket sealant, no matter what it says on the tube ! Good mechanics know this, bad ones (you know the type: get it out the door quick, doesnt matter if it still leaks 95% of customers wont notice etc) bodge with sealants.

Many OEM gaskets these days are much more then paper. They can have all sorts of fancy materials to seal built into them.

There is one exception to this, and this could apply to the OP, if the parts you are trying to seal are no longer flat / in spec then gasket gunk is the answer, but no guarantees it'll seal ! A good mechanic would / should explain this to the customer.
