davidll1984: I am relooking at your setup since I have an EGR valve now.

Questions:  1. What is the muffler output tube, snout, for on the engine or is it blocked and all the exhaust is going out thru the side into the blue goo into the bulb thru the black tube into the EGR valve?
           2. Why not use a different muffler without the snout, tube, ?
         3. Is this setup the “tuned pipe” you are referring too? So then all the exhaust goes out thru that blue goo setup to the EGR valve, or only a part of the exhaust?

   I got no instructions or drawings, zero, with the EGR valve, but it was really cheap.

Thanks for any help, or explanation you can give again.

In my game an EGR valve stands for Exhaust Gas Recirculation. The only purpose of it (apart from stuffing up the performance and reliability of an engine) is to reduce toxic emissions. What is the purpose of the "EGR" valve in this instance?

That's exactly what it means. It's the throttle control for the GTP Nissan and looks like a white box with tubes. I haven't seen it in real life and don't know how it works.

Off-topic: EGR is the culprit in causing many BMW diesel car engines to inadvertently set fire these days, causing BMW car recalls to dealer shops around the world..diesel exhaust gas recirculation into intake air reduces the temperature of fuel burn in the cylinder, thus reducing toxic NOx contents in flue gases, AFAIK.

I think a wrongly routed recirculation duct overheats in BMW-s and this setting fire to the engine

OVERLORD: the EGR valve is just below the blue goo and the bulb. The black tube is going into one end of the valve. The other 2 ends of the EGR are not connected as yet.

davidll2984:  i have  rear axle, only axle no gears, and a metal engine mount if you want to pay shipping.

I almost finished macbook so i still can't send photos. I broke a tiny flex cable from new keyboard to the main PCB.

Litle test of the modification

I have a little trick to start it easily the best is to prime it with the head removed from the engine With the exhaust open fulltrotle When the engine is well primed, the gas spray when it is cranked Try not to flod Then put the head back In cold weather it's harder I remove the heat sink just for the first start
