SOS! shreiking after oil pan swap/pumpswap

[fck]

well, after several frustrating hours of attempting to replace a damaged oil pan,
i filled er up and fired her up and heard a horrifying shreiking noise, smelled and saw a little oil smoke, and had the angry oil light buzzing and flashing at me. 

heres the low down:
i have been getting lots of extra pressure to my oil somehow, causing it to plume out of the dipstick tube seal near the block.

i have a large dent in the stock oil 1.6l n/a oilpan that led me to believe that there could be some interference with the pump/pickup tube to the oilpump.

went to a j/y and pulled a larger capacity oil-pan from a 2.0l mk3. stamping is similar, just higher capacity(deeper pan). i did not take the windage tray, as it was damaged, but i did take the oil pickup tube and the bottom of the oil pump itself.

swapped out the pickup tube/bottom of the pump later this evening, *****i'm not sure if i put it back right*****  is there something i can *** up here? there was a part of the oil pump (pickup? terminology here is lacking on my part) with a gear on one end and a shaft leading upwards on the other.  did i miss the connection there?


put everything back together with a new gasket on the oil pan, filled it back up with a quart more oil than i normally would, and fired it up.  i got a **horrifying shrieking** upon stardup, at a high pitch and intensity, my ears started shutting down, i think.  think jet-fighter loud.  or "little too old to be at the concert but it's a chance to recapture her youth so she says 'WOOOOOO' all night too loud".

what have i done now?

If I'm reading this correctly you removed the oil pump? If you did you oil pump may not have properly meshed with the vacuum pump. You could remove the vacuum pump and see if there is damage to the bottom of it or if there are metal shavings in there. While you have the vacuum pump out, pull up on the oil pump shaft. If you can lift it you're going to have to take the pan off and tighten up the oil pump bolts again.

Regarding the extra crank case pressure. Have you checked to make sure there is not an air leak in the vacuum lines from the vacuum pump? Did this happen all of a sudden or has it been gradually getting worse?

[fck]

yes, removed the pump to change the pickup arm/bottom part of the pump.

i will remove the vacuum pump and see whats what in there...
i was under the impression that the orientation of the vacuum pump is opposite the side of where the oil pump is? i'm kind of turned around from last night.


i have not checked for a vacuum leak just yet,
but it has been getting gradually worse. 
it was mentioned to me when i made a thread about oil spurting out of my dipstick tube where it meets the block.  yikes.

where can i source new a new vacuum pump?

[fck]

also, can someone tell me/show me what/where all the vacuum lines are?
I see one from the brake booster to the pump (hard, black plastic)
and a very small diameter yellow line leading to the a/c controls inside.

are there others?
and how do i test for leaking?
it's hard to hear anything when the motor is running (especially now)
and difficult to see cracks, i would imagine...

It almost sounds like you replaced a diesel oil pump innards with a gasser oil pump innards. If that is possible, would the oil pump try to pump oil backwards through the pan and out the dipstick?   

[fck]

ah, the oil spurting out of the dipstick tube was happening before i changed anything.

it was the reason for the swap in the first place.
let me be clear though,
i didn't change the entire pump,
just the plate that bolts to the pickup tube and the pickup tube.

I'd recommend not running your engine at all because it sounds like you have no oil pressure.

You could try removing the vacuum pump and spinning the oil pump with a drill. You will need a 12 or 13mm socket. Try turning it by hand first.

The shrieking could be the timing belt rubbing on the IM shaft pulley. You might want to pop the timing cover off as well and have a look at the condition on the back (non-toothed side) of the belt.

You have all the vacuum lines covered. What I would do is remove the one for the HVAC controls and plug it and see what happens (after you sort out the above problem)

Thanks tyler.
i will definitely check the oil pump after pulling the vac pump when i get a chance early next week.
i'm sure both of these pieces are original to the car, and could probably stand to be replaced.

i listed the replacements i'd like to pick up, but i'm not sure if they are fully compatible with my 86 n/a diesel golf.

Neither of those parts really wear out. I'd save my money for other things.

The oil pump could be bad. There are specs in the bentley for checking it.

[fck]

many diesel dudes in my area are suggesting that my bottom end is simply worn out.

the pumps are ordered, but i might try to cancel if they aren't sent.

would crankcase pressure issues be caused by bottom end issues?

motor has almost 500k on it,
the head appears much newer,
but the bottom end is o.g. for sure 

[Vincent Waldon]

would crankcase pressure issues be caused by bottom end issues?

If by "bottom end" you mean rods and cranks and their bearings... my answer would be "nope"

If by "bottom end" you mean cylinder bore and piston ring wear... my answer would be "yup".

[fck]

any/all.

i'm working on finding at least a bottom end to rebuild,
or maybe swap in a 1.9l n/a industrial motor a buddy of mine has laying around.

[745 turbogreasel]

if you turn the motor with a wrench, does it squeak?
the noise might be a lot easier to pinpoint without all the racket of a running engine, and who knows what clarancing itself into oblivion.

[fck]

well, this turned out to be a lesson in working at night without much light. 

after i slid the oil pump back up the first time, i didn't realize i hadn't lined everything up properly, and the tab of the oil pump spinner didn't get into the vac pump the right way, so it was spinning against the spinner dealio without being put into a tab/slot. 

took the pan back off, saw it in the daylight, it wasn't sitting against the housing properly.
sheesh. 

all is back together and well now.

now to look at the 1.9l swap.

now to look at the 1.9l swap. 

You mean now to look at your timing belt to make sure you didn't melt/burn it
