Hey guys.
Im about to pick up my friend's 88 GTI for pretty cheap (300-400
bones). It's got a broken crankshaft that I will be fixing. The engine
is a 1.8L 16v

While I've got the engine apart, I've decided to go ahead and just
completely rebuild it.

My question is can anyone make a list of everything I need to replace,
and things that I should replace?

Like all gaskets (head, valve cover, oil pan, etc etc etc)
mm..Oil pump - maybe? or just save for a later day?
Head Bolts, Main Bearings, Connecting Rod bearings/bolts

See I'm just kinda clueless to what parts I should actually be
replacing, and what parts are pretty much "never going to fail" (i
know all parts could potentially fail). I mean, if a seal is $3, i
might as well replace it right? What about the actual valves, no need
to replace those, right? but I should replace the valve guides/
keepers? Clueless here. Also, what about motor mounts?

Thanks for your time.

Assuming its just a broken crankshaft (doubtful). You need a crankshaft
irregardless. Replace the rod where the crank broke at minimum.

You have to clean all the parts. Get some gunk for it. Get
a ---complete--- gasket set for the engine. Else, buy the gaskets
separately as needed to create same. All bearing need replacement. All
piston rings need replacement. The engine piston bores need a hone cleanup
minimum. Might as well replace the oil pump while you're in there.

Won't know about the valves or seats until the head is pulled. Valves will
have to be turned at a minimum. Can be done manually with special tool for
that. If too worn, the valves will have to be turned on a machine to create
the correct angle again and the seats may be have to be machined as well.
Keepers and seals are always replaced. Valve springs need testing for
proper pressure at compression of spring.

Camshaft may need replacement, depending on wear. If so replace the tappets
as well. Replace timing belt.

Motor mounts are always replaced on a broke engine. Replace all belts.
Replace all vacuum hoses. Get the radiator pressure checked and cleaned.
Need oil and antifreeze, some break-in lube. Maybe some PermaTex for temp
hold on some gaskets. Replace all fuel filters including the one in the
rear of the car. Drain and clean the gas tank, allow to dry for few days
with all orifices open to the air, give it a few gallons of gas after
reassembly and installation.

Get the engine block head mating surface checked for squareness and evenness
across the mating surface. Have the machine shop look at the bottom end,
may be warped since the crank broke. Block could have invisible cracking
due to this as well. Be prepared to invest more money as the engine and
parts are investigated by you and the machine shop...

Money don't wag the dog's tail.

First determine WHY the crankshaft broke! You don't want to spend good
money and time and have it happen again while you are on the road! I have
not seen them break for no reason! 8^o

You will need to have many items professionally checked and/or machined.
Con Rods
Cylinder Head
Block

You will automatically go with new things such as bearings, seals, gaskets,
oil pump, etc.

Usually the Pass side engine mount is good to change esp. when the engine is
out, but if you want to change all 3 engine/trans mounts..We won't be mad at
you! ;-)

You will probably spend more on rebuilding this engine than purchasing a
used 2.0 16V engine out of a later A2 or Passat.
Have fun because it does feel good when you successfully do it yourself.
