ok i just got my built engine back and my dump *** used my original oil pump. should i not worry about it because i'm not goin to rev over 7200 rpms or should i get a new oem or an aftermarket to cover my *** and to have piece of mind?
please help. i need this engine in my car!

 

Why risk it, change out that ******. What engine did you have built?

 

d16y8 with vitaras, tt rods had it all nice and cleaned up and what not. oem or aftermarket?

 

Now I don't know for sure because I never owned one, but I THOUGHT that I heard those oil pumps were pretty weak. I don't know if you can use one from a Z6, but I think there are ways to mod the Y8 pump to flow better. I'm sure someone esle will chime in here. BTW, you should've posted this in hybrid/tech. It may get moved.

 

I believe you can use the z6 pump, but you will loose the dipstick. I honestly dont know how you could go without a dipstick but some do it.

 

ok i've been ------ searching as fast as i can. the y8 and z6 have the same psi but the z6 flows better. the reason y8 spin bearings is because the y8 isn't flowing enough. so i think i'm going to have the oil pump taken out before the engine goes in and i'm going to port it out and add a shim. from the things i've read it's not hard just takes some time.

 

thats the spirit!

 

I opt for the z6 oil pump, pan and pickup. You lose the dipstick, but if you change and monitor your oil levels right it won't be an issue.
