Oil Sump/pump problems

Hello guys!

 

So, 

I have a 1602, and instaled in there a 1.6L M10 from an e21 and after being fully assembly and fully running, i discovered a strong vibration in the steering wheel and in the car in general. The oil sump was different than the original engine and was hitting the under carriage.

 

I removed the e21 oil pan, and saw that they were a bit different (left original 02, right e21).

Now they fit, but im concern if im going to have any problems with oil pressure, or something related. Also, the 02 (first engine picture) engine had a bar to the crankshaft support, which i didnt put, otherwise, i have to change crankshaft supports etc etc... Could this be critical also??

would i be better with an e21 hammered down oil pan and original oil pickup oil part(dont know the correct name)

Let me hear your opinions, 

 

Best regards!!

I think most people who are fitting new oil pumps to 02 M10s are using a later oil pump with the pick up changed and the 02 sump just as you have done.

There are spec's in the blue book for the oil pump.  When I rebuilt the hot rod engine I just measured everything and it was within the spec's, so I used it.  As long as it measures good it should be good.  Oil pressure gauge maybe not a bad idea as well...

Is there any stock sensor for that or where can I put it?

VDO gauge with sending unit.  They go on top of the engine, back by the distributor.  You replace the stock one (sensor) with the aftermarket one.

I have one of those, just missing the black block for thread conversion

You DO want to swap in that support bracket-

you can simply move it from one engine to the other,

as it sits under the main cap.  Take the bolts, too, as

they are longer.

 

Otherwise the pickup is prone to breaking off from vibration.

The thing is:

the e21 crankshaft support that the bracket attaches does not have the holes for it.

i would have to change that support and the crankshaft bearing also.. 

am I wrong?

Look close at the E21 bearing cap.  There is a separate support anchor bolted to the bearing cap.  Use that anchor and the bolts from the E21, they are longer.  Do not swap bearing caps or bearings.

The support mount with the bolt holes for the sheet metal support is a separate part that bolts on top of the bearing saddle. You'll need that extra part and longer bolts off a 2002 to do what you want.

Ok, sounds good.

any idea of the tightening torque?

Check the specs found in the maintenance manuals on here.  You will need your torque wrench.  Get familiar with them, it's the straight scoop from BMW!
