drowz Posted December 30, 2007 Share Posted December 30, 2007 I just bought an 81 280 zx turbo for an engine donor. It's going in my 73 5 speed 240z. How do I take of the oil filter housing without breaking anything, seeing as I don't need it. Any help is greatly appreciated, as I am dumb on the subject. Thank you.

nbesheer Posted December 30, 2007 Share Posted December 30, 2007 Are you talking about the sandwich plate between the oil filter and the block ? Quote Link to comment Share on other sites More sharing options...
GrayZee Posted December 30, 2007 Share Posted December 30, 2007 Seeing it as the fittings for a oil cooler are already there I would take advantage of it and use it. You should be able to get Metric to SAE hose adapters at a good hydraulics shop. Then just ask them for some "push on" hose ends. Make up your own custom lines and run a oil cooler. You could even run the hoses in a closed loop for the time being if you want to hold out on getting a cooler. If you do want to remove the system altogether, I think there is a hex that you can get a wrench onto at the base of the threaded shaft the oil filter screws on to. Of course you will need the parts from your old block to replace them with. Quote Link to comment Share on other sites More sharing options...
nbesheer Posted December 30, 2007 Share Posted December 30, 2007 Well if it is indeed the sandwich plate you are talking about, I would be interested in picking it up off you, and if you want to keep it, I have a FC RX7 Oil cooler for sale if you're interested.

mario_82_ZXT Posted December 30, 2007 Share Posted December 30, 2007 The sandwich plate on the Automatic ZXTs has something in it that is internal in the non-turbo or manual turbo car's block. You need to use it, as you cannot simply replace the stud with the correct one. I believe it has a bypass valve that is otherwise cast in the other blocks. Search on it, it's been discussed. I got the SAE adapters for mine and just have it looped, I'm waiting to mount the oil cooler till I know what my front end looks like.

HowlerMonkey Posted January 1, 2008 Share Posted January 1, 2008 On the turbo automatics, there is a blocking plug on the block within the diameter of the oil filter sealing surface for a relief valve. In all others, there is a bypass valve in the same place to keep pressure at the filter below what would explode from either overly thick oil in low temps or a clogged oil filter. In the turbo automatics, the bypass valve is in the housing that feeds the cooler lines. I've run without the cooler and bypass for years on my cars but you must make sure you change the oil filter before it is clogged or the pressure rises in the filter. I prefer my oil filtered all the time rather than have it bypass and not get filtered. Quote Link to comment Share on other sites More sharing options...
