I have searched and i can't figure out how to get the dipstick tube to stay in the hole on the block. I have a 3rz, bought the 2wd t-100 oil pan, and all of the parts but do I need a coupler like 90405-10033. I see it mentioned on when this is used with the 6 cylinder engine but haven't found it referenced for the 4 cylinder. Any help would be appreciated. I am waiting on this before I can put this car back together. cheers ian

As far as the block goes, it just a press in.(Hammer time) but what coupler are you talking about. If the motor is from a Tacoma you just need the Oil pan. Are you talking about the oil pick up tube???

Need more info.

So it is a tacoma 3rz 1996. I found the new hole where the pickup dipstick tube goes, on the drivers side near the motor mount. So I just hammer the pickup (dipstick) tube in until it is snug? when someone puts the t-100 oil pan on the six cylinder, they mentioned using this coupler between the pickup tube

Do i need this?

why do you need to know your oil level????? change every 3k and your gooood!

You dont need that crap. Just the pan, new pick up tube and dipstick.

End of story.
