freeze plug.
water pump is the wrong size.
vacuum leak on one of the brake hoses.
and a mysterious oil leak from above the water pump (cant see exactly where) that shut down my car todat. felt like it was losing pressure and now it wont start. this car is a fucking pain in the ass. still love it tho.

so with this being said there was only one thing to do........

start taking shit apart.

just started taking the car apart

where is the leak?

grrrr

depressed...

just finished tonight. havnt found anything. i dont want to have to take off the timing belt (never done it before either). but so far i figure its nothing i can get to (at least i think) and i might have to take the engine out. maybe ill do that r154 now. anyone know why my car would have symptoms of a vacuum leak but be leaking oil and steaming/smoking at the same time? i think the steam was mostly from the freeze plug. but the front of the engine still has a little bit of oil on it. ooohhhhhh yea. there was a huge gap in the water pump (since it wasnt the right size) but i wouldnt leak oil right?

hmmm, loss of pressure, leaking oil, smoke.. I'd have to start thinking my HG was blown... but then again, I've thought that about 3 or 4 times since I've purchased my mk3 a few months ago... mainly cause the head gaskets go sooo easily on these 7m's... grats on your purchase, hopefully it wasn't in vain... I've enjoyed the time I've had her so far, but have had to (and still need to) put her in the shop for repairs..

what was the problem with your car?

Pull the timing belt and look if the oil is coming from behind the black plate behind the cam gears. If so it's either the cam seals or the valve cover seals. If not the it's either the oil pump seal, the crank oil seal or you're leaking from between the head and the block.... has the head gasket been changed on this engine?

The coolant leak behind the water pump is either an eroded hard line assembly which runs along the side of the block and wraps around the back of the engine or the 90? hose which connects to it right under the thermostat tower. The hard line is no longer available from Toyota, if that's what's leaking you're going to have to either fab a custom replacement or buy a used one.

Switch to Toyota's red coolant, it has better dielectric properties.
