Hey there!
I have a 93 TD42 Patrol,
Long story short.. I drowned it 2-3 weeks ago, water got sucked in through the air box and the car shut off almost instantly. I got my mate to pull me out.
Waisting no time, We then pulled the glow plugs out and cranked it over. Drove 2 hours home as I had no other choice.
Now in the mornings the car runs rough and blows white smoke. But after about a minute of driving it drives fine, no knocking sounds on idle, no loss of power.
It does have a slight ticking noise under load. I noticed my #4 injector was leaking. Glow plugs are all working fine.
I also did a compression test the results are as follows;
Cyl 1: 430psi
Cyl 2: 410psi
Cyl 3: 420psi
Cyl 4: 240psi
Cyl 5: 410psi
Cyl 6: 380psi
My mechanic suggests I change my injectors, injector pump and glow plugs
My question is;
Could the leaking #4 injector be the cause of low compression in cylinder 4?
