Neveragain55 Posted January 4, 2012 Share Posted January 4, 2012 (edited) Ok Gang, All of the parts for my turbo rebuild have been procured and even painted with POR 20. I’m at the stage where everything is ready to be bolted back together but I have a dilemma. I don’t remember there being a metal gasket between the "7 bolt" turbo housing and the "7 bolt†internal wastegate exhaust section. I’ve looked all over the internet and all I see are “5 bolt†metal gaskets but not 7 bolt metal gaskets. Were their no gaskets that went between these two sections or am I just not looking in the right places? I’ve attached pictures so you all can see exactly which two parts I’m talking about including a picture of a 5 bolt gasket. As Always, Thanks………… Edited January 4, 2012 by Neveragain55 Quote Link to comment Share on other sites More sharing options...
kaito Posted January 4, 2012 Share Posted January 4, 2012 If its the stock 280zx t3 then there is a gasket that goes there and it is a 5 bolt gasket. Not the one you have pictured though. Try this boss, http://www.ebay.com/itm/T3-T4-5-BOLT-TURBO-TURBOCHARGER-DOWNPIPE-PIPE-ALUMINUM-GRAPHITE-COATED-GASKET-/180786149909?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item2a17b1ba15 Quote Link to comment Share on other sites More sharing options...
Neveragain55 Posted January 4, 2012 Author Share Posted January 4, 2012 Kaito, It is an original T3 turbo that came with the car and I looked at the metal gasket on eBay from the link you sent me...... But there is a large area of material that would cover the actual internal wastegate if I used this gasket. Would that be correct? Wouldn't the wastegate be blocked if I used this gasket, or I am completely off here? If the one you sent is the one that should be used then I'll definitely get it. I just want to be sure. Thanks for your help....... Quote Link to comment Share on other sites More sharing options...
dexter72 Posted January 4, 2012 Share Posted January 4, 2012 I have 3 stock 280ZX turbos and none of them have a 7 bolt gasket. It seems like they are a machine flat fit and no gasket is needed. None of mine have leaked there. You will need a gasket on the back of that Wategate flapper housing though. If you put it on upside down that will leak, Ask me how I know. lol Quote Link to comment Share on other sites More sharing options...
Neveragain55 Posted January 4, 2012 Author Share Posted January 4, 2012 (edited) Thanks Dexter, That actually makes sense because I can't seem to find a gasket anywhere (internet or otherwise) that would fit between the two housings perfectly, and like I said in my original post, I couldn't remember seeing one when I ripped it all apart. When you say (You will need a gasket on the back of that wastegate flapper housing though) you’re talking about the four bolt pattern where the exhaust bolts on right? Serves me right for not paying closer attention…… Thanks for all the help gang........... Edited January 4, 2012 by Neveragain55 Quote Link to comment Share on other sites More sharing options...
kaito Posted January 4, 2012 Share Posted January 4, 2012 By bad, there is another one on eBay with the hole for the waste gate. Just search for t3 or t3/t4 internal wastegate gasket Quote Link to comment Share on other sites More sharing options...
dexter72 Posted January 4, 2012 Share Posted January 4, 2012 Yep that 4 bolt pipe. I call it the down pipe. If you put that gasket in upside down you will have an exhaust leak. Whooops did it a couple of times myself. Quote Link to comment Share on other sites More sharing options...
deaner Posted January 5, 2012 Share Posted January 5, 2012 If it's all still taken apart, plane both surfaces and just use high temp orange. I quit runinng gaskets on everything turbo back years ago. Plus most of those metal gaskets are crush gaskets that only really work the way they're supposed to once. Good luck! Quote Link to comment Share on other sites More sharing options...
Neveragain55 Posted January 5, 2012 Author Share Posted January 5, 2012 (edited) Deaner, I was actually thinking the same thing because I’ve searched the internet, turbo parts suppliers, & eBay high & low and I’m not seeing a gasket (made from any material) that will fit that 7 bolt configuration which seriously leads me to believe there never was one. And if there were gaskets used (back in 1982) there sure as heck aren’t any available now. I’ve mated them in a test fit and the surfaces mate up perfectly with no gaps so I think the high temp orange sealant is a viable option. The biggest take-away I’ve learned from all of this is how important it is to visibly look and check everything before it’s pulled apart. Something I already know, so shame on me. Thanks everybody………. Edited January 5, 2012 by Neveragain55 Quote Link to comment Share on other sites More sharing options...
deaner Posted January 5, 2012 Share Posted January 5, 2012 I hear you on hard to find little stuff. Those gaskets being one of them. Got tired of searching for random little wastegate gaskets or T3 gaskets everytime I took things apart. The past like 5 years high temp orange is all I've used. Unless it's a car that never gets driven or worked on(IE it get taken apart more often than not lol, tinkering) the stuff is perfect. Goop it on, tighten and clean off the excess. Done!

Neveragain55 Posted January 5, 2012 Author Share Posted January 5, 2012 Deaner, No worries on the double post (we’ve all done it) I’m definitely going with the high temp sealant. Permatex actually makes a whole range of high temp sealants that surpass the “Orange†high temp sealant. So I’m going to do a little research and try to get the sealant with the highest temp rating as these turbo’s get pretty hot. Thanks for your input, much appreciated…..
