    Diesel stuff

    Hello all, Does anyone know where I should put the EGT sender for my Pyrometer. One fellow at the Scout Nats said on the Turbo diesel to remove the small tube coming off the exhaust manifold near the firewall, looks like it goes to an EGR valve of some type. He said to remove this tube with the valve and bolt a small plate over the hole and the sender should go there. Is this correct? He also said that removing this tube and valve will not have any bad effect on the motor running and will actually add a little power, like 10% or something. My manual is for the sd33, not the sd33t so it doesn't show this in it. Anyone wanna trade manuals? I'm adding a few gauges to monitor the beast for longevity and would like to boost the power up a however much I can without hurting longevity or dependability. I have asked the guys on the diesel page last month but haven't heard anything. Any help would be appreciated...Kev, also anyone know where I can get a tach for it new or used? thanks ........................................... Ok......... Part II ,Sorry its something I posted last month on the tech talk and didn't get much back. Probably cause its too long but I ,...Oh well, here it is.........Hello, I'm glad to find this site. If you have a a couple minutes I would like your opinion. I recently bought a 1980 SD33T and tranny with 57K for $500. It has been setting for about 4 years. It turns over free, the turbo is free and the waterpump is free. The alt. was locked up from internal rust so I disassembled is, carefully blasted the rust away,cleaned it and checked the bearings,(good) replaced the brushes and vac pump seal and reassembled, turns out its fried. The motor is still setting in the scout frame with a t19 bolted to it. It has been cut off at the tranny rear mount and looks like a good platform for running the motor and seeing how to work on it and such before any possible drop in use. What I have planned is to replace the oil, filter, fuel filters, air filter, remove the valve cover and check to see the valves are all free., flush the block, disconnect the fuel inj. lines at the pump and head and flush them w/carb cleaner. Thats about it and try to fire her up. If this were a gas motor, I'd remove the carb and do a thorough internal cleaning and rebuild but the fuel inj. system looks WAY beyond my capabilities and all those special tools WOW, I don't have any of them. Have you got any suggestions of do's or don'ts? Setting is the worst thing to be done to a motor short of running it w/o oil. I am a little concerned about the valve seals being shot from age and setting. I didn't get a radiator w/ it so I was gonna use a spare V8 one I have. make up a mount for it and also connect an oil pressure gauge to check the pumps function. I may also go ahead and drop the pan and clean it out and replace the old gasket. Would you suggest an internal engine cleaner as sold at the local parts store. I have had mixed results w/ these products like Rislone, on a couple of old gas motors, the lifters promptly collapsed. I have just bought a beautiful all original 1980 Terra diesel w/62K and bought this motor as a spare and for a test bed and source for spare parts and basically to play with, I am new to diesels and the parts are expensive individually so this seemed like a great way to get broke in. Its all there for me to see and run and work on. I'm also considering possibly options for upping the power a bit if it proves to be the dog that everyone claims but I drove a non turbo diesel back from Texas and asside from the beginning acceleration I thought it was OK for power. I do have a tool trailer and a boat both which weigh about 2K lbs so I'm curious about its bility to pull these ocassionally. A fellow near me has a Diesel traveler and claims he has a low pressure (1 psi) propane injection on his that he turns on before a big hill and says it works great and would probably do even better on a turbo diesel. A fellow at the Nats this year told me that by disconnecting the EGR valve he gets 20% more power and by doing something to the waste gate got a little more by bumping the boost up to 9 or 10 psi. Hmmm, Risky? I was really wanting to try out an intercooler for the turbo but he said it won't do any good on this motor. I can't imagine it not helping keeping the pistons cooler. And also I think a good EGT gauge would be nice for keeping the beast within limits. WOW, sorry, I just really loaded you up! Didn't mean too but I've been tossing all this stuff around in my head and it just flew out. I realize that once you start trying to pump up the power above design limits you also risk reliability and longevity but also think that carefully done there might be a good balance there someplace. Lots of thoughts for a guy who is still working on what makes a diesel tick HUH? Anyway, again, sorry for the long message and if some of these are repeat ???s thanks for any help you can give.....Kevin (proud member KCFD)
