Thanks DDgonzal! I have 10 more questions (for now.......
:
1. If cylinder bore is ok, can I reuse pistons and simply hone and replace rings? No need to replace pistons with this size dish that is matched up with GX head?
2. Turn crankshaft and replace bearings. I have some end play, which will need to be repaired?
3. Replace camshaft and lifters as you noted. Install new cam bearings. Can I reuse the pushrods from the A15 cylinder head?
4. Do I replace freeze plugs?
5.
http://datsun1200.com/modules/mediawi ... shaft_replacement....This link indicates more than 15mm extension of the tensioner replace the timing chain. If so, can I reuse the gears or replace both gears as well?
6. Replace oil pump?
7. Expect to replace all GX head valve springs?
8. Will plan to get the cylinder head rebuilt. Any advice here? History of A12 engine is unknown.
9. Will the GX exhaust manifold work that I show in the pictures? Is this the stock GX exhaust? I couldnt believe what someone was asking for this in the classified section.
10. Carbs will need to be rebuilt. Any additional information on these based on what you see in the pictures?
Any response would be greatly appreciated. I am sure I will have many more questions later on. I did have an opportunity to talk with Peter Zekert and he advised not to bother with dipping the block in any harsh chemicals when it goes to a machine shop and not to replace any freeze plugs. The A series blocks have longevity and dont require much if your wanting only a mild rebuild. Let me know what you think about that.
BTW, history on the 72 coupe is that the previous owner bought the car for the body only and put a 240sx motor in it and was parting with the A12 engine and transmission. Unfortunately its the 4 speed. I have read where the 5 speed GX transmission is very rare.
