timing chain on 3.1

[alfi1]

on lumina 1991 3.1 l ,i want to replace timing chain and the 2 gears (cam and crank) (noisy) (189,000 km)

i read in the chilton manuel that i must remove the oil pan

my question is:

is it possible to do the job without removing the oil pan?

[Robby1870]

On all the motors I have worked on, the timing cover has atleast a couple of bolts that also bolt to the oil pan.

That's true. I've rebuilt a couple of 2.8 MPFI and 3.1 MPFI engines, and they have two three two bolts connecting the cover to the oil pan.

ohh i forgot something

concerning the first question, the manuel say that i must purge oil and coolant before removing the front cover.

i can understand for oil but why the coolant?

there is no coolant in that cover...

 

thank to reply

Because the water pump is inside the front cover
