My son has a 93 240 Ka24de that has been built up with Turbo new pistons head studs ect ..we keep blowing head Gaskets ....last time we Flat checked the head and it seemed ok ..
The story we get from the shop that is doing the work is that the stock head Gasket is the problem ....anyone know of a Company that makes or can make a metal head gasket . . thanks

 

http://www.scegaskets.com/index.html u can chek out these guys..maybe give them a call or email them.

 

Thanks ....I'll check them out ...just briefly I see they recommend ringing the block for their Copper Gaskets ...we did that on the first Blown Gasket and our shop said one of the o-rings was too low ....causing the gasket to blow ...That cannot be redone so machine shop replaced the block ....but this time ..we didnt ring the block ....and have been using stock gaskets which seem ok at 5-8lbs of boost ......but at 11lbs or more it blows ....thanks for your imput .....

We installed a new Nissan head gasket and found a cpl of problems ...one was when we removed the head we found the head studs we pretty loose into the block .....4-5 turns to bottom out ..now the specs call for hand tight but I would think they need to be snug ...after putting things back together we found quite a few vaccum leaks ...but the main thing was the timing was at 27-28 degrees . The guy helping us said 20 was normal ...not sure if thats spec and we put it @ about 17-18 .....car seems alot smoother idles ALOT better .....He seemed to think Detonation was maybe the main problem ....we'll see ....

 

I'f your problem was detonation be glad just head gaskets blew. Let us know if it helped the problems.
