Now the glow plug light doesnt light up unless I turn the key 3 times. I did a compression test and all cylinders seem to have ok compression, all are above 300 except #5 is just under 300. I replaced the heat shield washers under the fuel injectors, hoping this would solve my problem. I also pulled the valve cover off again, thinking maybe I adjusted the valves wrong or something, but everything seems to be fine. I'm 16 and I dont know what to do anymore. Please help! Thanks. -David
Hello David

Here is how you should look at the vehicle now..

Ignore anything related to your 300d 4 speed manual conversion, and STOP mentioning it = it only stresses you and adds nothing to an engine performance issue..


You performed a Basic valve adjustment, using dieselgiant DIY. = Important Diagnostic DATA...

The car starts up really rough with lots of white smoke. = Important Diagnostic DATA...

It smells like it runs rich or something and it randomly misfires, no matter if the car is warm or not. = Important Diagnostic DATA...

You changed all of the glow plugs, but the new unit on #1 cyl was broken/damaged/defective, and you replaced it with a used one. = Important Diagnostic DATA...

After replacing the damaged NEW #1 unit with a USED glow plug, the glow plug light doesn't light up unless the key is cycled three times. = Important Diagnostic DATA...

Piston cylinder compression test numbers are:
#1. 360 PSI
#2. 350 PSI
#3. 320 PSI
#4. 310 PSI
#5. 295 PSI

The cylinder head would be coming off if this was my engine.

The numbers are indicating (at least) a failing cylinder head gasket.

You replaced the heat shield washers under the fuel injectors. = Important Diagnostic DATA...

You re-checked the valve adjustment, and it seems OK..

You are 16 and are seeking advice, in what has become a stressful situation. = wisdom and letting members know your skill level.
