Oil pump leave alone or replace

[95Escahoe]

If my oil pan gasket is bad and needs replacement would you do the oil pump too? Since your right there anyways, trucks got 255k miles on it and runs great no issues and want to keep it that way, who knows if the pump is original or not

you could replace it while youre in there if you wanted to. if you have good oil pressure i wouldnt worry so much about it

I wouldn put a cheap one in it if i did it. Personally i probably wouldn touch it, but it couldn hurt.

No more than an oil pump costs, it'd be a no brainer for me while I was right there. Your old one may go another 100k miles, but I always do the "while I'm at its".

I replaced mine while I was in there. I take advantage when I do many to take care of whatever I can while my rig is down.

Whats a good brand to go with? Is Melling any good?

 

[polar]

Yes melling high volume

 

[95Escahoe]

With a high volume one, wouldn't I need a bigger oil pan? Cause they make stock replacement pumps and the high volume ones

I read that on the TBI engines you would want to go with a melling high pressure standard volume. Otherwise you will starve the pan and flood the crank case.

Here is the exact quote:
"Unless you prep the block properly you will end up sending too much oil to the hydraulic lifters and pump them up too much causing vacuum issues and poor performance. I use a std volume, high pressure pump http://www.summitracing.com/parts/MEL-M55A/ and its better than stock TBI oil pump"

Also I think that pump can be had from amazon for less and with prime free 2 day shipping.
