Lastnight i raced a guy that thought his v-tec was fast bohahaha!! but in the process of wiping the asphalt with his dinky toy i know i know i shouldnt pick on the smaller guys!! But he was asking for a wooping so nicely!!, i blew one of my manifold gaskets AGAIN!!!! this is becoming a huge pain in my butt! this will be officially the 4rt time im replacing the gaskets!!
Make sure you only use nissan manifold gaskets, and tell them to make 100% sure its for the turbo CA or SR, they are different, the little compressed silver gaskets that are available on average last 2-3 week...
If you can try get the nissan multi layer stainless gaskets, I know the gasket kits i sell come with them but im not sure where you could buy them loose, next time ill get the direct part number for it, they arnt cheap but it sure is cheaper than taking your manifold and turbo off every time.
Join the club Jay Boy. I replaced more than 4x times. For sure it is more than one factor adding to this problem. Rezlo, please let know if you can assist with this. We had similar discussions on this topic before. But surely we cant get enough knowledge on this. Rezlo it is me who bought the irridium spark plugs from you. Great.
its all in the quality of the gasket and the corect torque method when installing the manifold, if you fear your manifold isnt straight have it surface ground (normaly costs like R80 at a machine shop) to make sure its 100%,
Unfortunatly it doesnt look like i can get them loose, only in the gasket kits,
maybe if you are having so many problems with it its worth getting a nissa or acl gasket kit, have the manifold ground slightly and replacing all the gaskets while your in there because labour to remove the manifold each time must cost you quite a bit because its a pretty envolved procedure doing it.
Re-torque when cold, and make sure you crack the nut loose then tighten!! I managed to buy loose gaskets for a CA18 and they are working fine. I put new ones when I redid my turbo and re-torqued them after 1000km. I put them on with silicone, I know you not ment to but I have always done it and every car I have fixed and not 1 hastle.
One step better than silicone (which cant hold that mount of temp) is Wurth exhaust seal, its about R40 a tube and dries fast so you got to work with it fast, use it very sparingly,
And if you gentlemen wont mind - retorque - with what? Is it one of those fancy torque wrenches? You all know how difficult the back bottom nuts of the manifold are to access.
I have a wrench addapter but i never use it on those, i do it by hand, its more the sequence you use than anything else, also Ive never found the need to re-torque the exhaust manifold studs when using the correct nuts and washers
I just used the normal silicone you get, its not rated to the temp the manifold gets to but it still works. I just crack the bolts loose and then make them FT (F##king tight) . Dont use a torque wrench just a spanner and pull VERY hard. You can also use fire-gum, but that stuff dries very quick so you better be good at putting it back on. Any spares shop should have the gaskets, ask for the CA18 not the CA18DET.
Jay! hoezit!
I just had a thought this morning when I drove my bebbiee to work - mine's idling is rough, so the engine shakes a bit. To make a short story long if your engine and gearbox mountings are fubar, then there is much shaking and flexing on your zorst, which I scheme will fubar your gasket in time.
