I have been using my rebuilt 453 for months now with no complaints...Thanks to all those that have helped me get it back to work(Tazza, Old Mechanic, etc..) Anyway, my neighbor has a 453 just like mine but probably a little newer and I have been helping them with repairs and maintenance. Had to...

Tazza, I do get fuel pressure if i crank it over and check for fuel at the delivery nozzles.

The hose is not part of the injector system it is just below the lift pump so a coolant drain would make sense but when i tried to turn the valve it wouldnt turn and i didnt want to break it so i just left it. I did try ether and wd40 and neither of them made a difference in trying to start it...

They didnt say why the injectors went bad. I was wondering about my pump as well but the lift pump is new. I put one on when i rebuilt the motor. (Maybe it wen bad??) My fuel shutoff is a manual pull cable and when i pull it to the off position it moves and then springs back to the on position...

More on my 453. I had it running for a month and it ran/started really good. Then on Friday I went to use it and it started fine but then after using it for 10 mins or so it strated to run ragged. Almost like it was running out of fuel(3/4 tank). Well, i took off the injectors and brought them...

Also, forgot to add there is a guy that i know who said he would like mine when i get it fix and possibly trade/trade with cash for a S130 because he needs a little one for getting in small areas. I seen him driving his S130 and using it so i know it works but what should i look for on a used...

Well, i figured out the problem(s)...two seals on the fuel filter,i forgot to take the old on on off...DOIT!!! Also, there is a little ring on top of the injectors that has two holes in it. There is one hole on the top of the injector that had to line up with. This ring is between the injector...

I got an update on my 453. I fianlly got it all put back together...new rings, new valves, ridge ream and flex honed the cylinders, and the head rebuilt and vacuum tested and adjusted the rocker arm tolerance to spec. Put it all together today and cranked it over for its maiden voyage. However...

Tazza, do you have a repair/rebuild manual for a D750? If i have to replace the rings it would be nice if i had something for it to look at. Otherwise, where would i get one? Should i do the bearings or how do you check if those are good?

An update. Today i pulled the engine(THX FOR THE PAGES OLD MECHANIC THEY HELPED A LOT) and took the head off. The valves on the bottom side had alot of carbon build up and even some small chunks of carbon. I called a a buddy of mine who owns a machine shop/engine shop and he said he can clean...

ok. I will plan on yanking the engine out. I have a workshed with a nice bench to use so i will just do that. Is there a way to put these in nuetral to roll them or is it easier to just crank it over as it is now and drive it on a trailer?

Ok. Thanks for all the help guys. I think i am going to tear into the head tonite. Should i yank the engine or can i look at the cylinders with just the head off? If i can inspect the cylinders with the head off would that be easier to check or should i plan on yanking the engine and do it that...

Thanks a million for these. They will come in handy. Ok, this morning i pulled off the valve cover and when i spun the flywheel byhand i could watch all the valves moving with the rocker arms. However, on cylinder 3 the furthest from the flywheel, the valve on the right (when looking from the...

Ok. I was also told to take the valve cover over and check the valves as i might have a stuck valve as well so i am going to tear into that so anything that you have on both of these would be helpful as i have not gotten a manual yet. There is no real hurry but i do have a couple of jobs lined...

Also, when i did the test, my adapter would get alot (almost dripping) with black fluid probably oil. Is this all the same problem or could this be something else?
