my 95 psd's having issues

[95strokerpaul]

i just bought it (95 F250 PSD 4x4 5 speed), and two days latter it died on me. Im thinkin its a cam sencor, but now it has a miss and a ton of blow by comeing out the dipstic and oil filler cap. Anybody have any ideas?

I'm not great at this but I will see if I can help. First remove the valve covers and run a compression check to see if all the cylinders are equal. See if you can narrow down which cylinder is not firing correctly.

take out the injectors to test comp. Right?
should i just go ahead and put new injector O rings in?

No. you dont have to remove the injectors. All you have to do is get the valve covers loose let the truck run for awhile to get warmed up. Then remove the glow plugs and put an adaptor in the glow plug holes that will connect to a compression gauge made for a diesel. Then with the key off use a remote starter connected to the starter solenoid on the fender. let the engine roll over 5-10 times and see what the gauge reading is. Its best to remove all of the glow plugs first when doing this so its less load on the starter. I beleive the cylinders should all read within 70% of the highest pressure. Part of the problem with taking out the injectors is if you dont drain the oil and fuel in the cylinder head when you remove the injector all it goes into the cylinder. Hope Im not confusing you.

If you have blowby coming out of the dipstick and filler cap, you probably have big problem with one or more cylinders, I have seen tips break off injector nozzles and melt down pistons and bend rods

Nathan, thanks. not to confusing ill giv that a try
AWORM, thanks for your input thought thats not what i wanted to here. but at least i can pepair my self. thanks again guys!

If you have blow by it's because your rings are worn out. So chances are you have low compression.
