Default About to buy a BP from a 2002

Hi, I'm expecting to pick up this engine this week end.

It's a BP-Z3 (BP-VE) from a 2002 NB, said to be low mileage.

The A/C and starter were sold but everything else seems to be there.

I would like to know if there is particuliar things I should double check before buying it.


I was expecting to pop the sparkplug and take a look inside the combustion chamber with a little light.

But I don't know what else I could do without a starter.


I'm not familiar with the variable plenum and the VVT, I actually have a 1990 1.6L


















Thank you, I'm waiting for your replies!

im guessing motor is out and not running. Leakdown test.

leakdown is supposed to be done on a warm motor but since you dont have that it will suffice on cold. basically you want consistency across all cylinders and less than 30% leak. when running the test if there is a decent amount of leak you'll hear the air from the test escaping from the exhaust side of the motor, intake side, dip stick shoot, or somewhere in the coolant route.

exhaust leak is most likely valves stuck open do to carbon or bent valve. same for intake leak. a lot of loss out of the dipstick means most likely warn cylinder walls or ring issues, coolant is head gasket issue. I just went through this with a 99 motor and the valves weren't seating so i got a valve job.... while the head was off i took apart the rest of the motor and decided to do a full refresh plus some new rods for mo boooost.

could have gotten away with just the valve job.

if you're interested i did the leakdown myself. i went to harbor freight bought about 20 bucks worth of gauges and a pressure regulator and made a tester myself. took my small air compressor with me and tested on the spot. if you find failures then you can adjust your price accordingly. if you're lucky the seller of the motor can test it for you. if you're interest in doing this then i can do a more detailed right up but if you're not interested you can always just buy and drive and cross your fingers.

Thank you for the quick answer!

I would like to know how you did the leak down tester!
That would be the good way to test the engine!

so, I guess spending a few more bucks for the VVTUNER to add to my MS1 is totally worth it?

No. Selling your MS1 and upgrading to MS3X is totally worth it.

Hmmm.... I know, but for now, I will just swap it into my 1990 and make it work with my MS1. I hear you already, but, MS3x is still an option!

So no VVTTuner ?

MS3x can do all of this? or is it a little bit overkill, no A/C, no cruise control, no power steering....

Looks like the connector for the cam sensor is broken?

Oh, good thing you pointed this out, but where is it suppose to be, I cannot see it?

In front of the sprocket from the exhaust CAM or at the rear of the intake CAM?


***EDIT****

I see it now :

I'm going to just link the info i used to do my test. If you'd like me to write up in depth instructions out side of this i will but this should be good enough.

howto make a tester:
instructions on testing:

you can get all the gauges and pressure regulator , air hose, and fittings from harbor freight. my tester worked fine regardless of the cheap harbor freightness. i had a compression tester and just used that hose. the only tricky thing to fine is a #60 bit. you can either order it online or check a hobby shop. lowes or home depot won't have it. i got mine at the largest ACE in western united states so if you have any specialty stores like that they may have it. if you don't have a compression tester already it doesn't hurt to have one in your tool arsenal if you can i'd snag one of those too. just keep in mind when you buy one. how youre going to connect the hose to the leakdown tester.

example. my leakdown tester has a fitting on the end i was just able to screw on to an air hose. i'll take pics when i get home. some compression testers are all built into the hose. you need to be able to remove the valve if you use that type.

No, at the rear of the intake cam on the top of the valve cover.
