so i got the car today. absolutely amazing. ive always wanted a supra (any year) since i was little so this is kind of a dream come true. barely any body damage. minor paint fading. needs a clutch fan, and just need to replace a few hoses. $700. the only thing i cant wait to do is put in that r154. oh so thank you all for the help. cant wait to start posting up some build threads

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.

ok so just an update. i almost have the head off and am ready to have everything take to the machine shop. but me and my girl had a sudden realization. our engine has 240,xxx on it, its non turbo, and were pushing this build to close to the amount of a rebuilt 7m-gte......... so why not get one?

in the net couple days were going to be checking out some engines to see whats up and what our possibilities are.

i know theres not a whole lot of people reading this but......

journaling is fun.

PEACE!

That's what I was getting at... you're gunna spend soo much money fixing the 240k 7mge, and you still wanna swap... you might as well do the 7mgte when you do the swap... might have sound mixed or confusing since I think when I was trying to point out the 7mgte would be a quicker swap with less of a price tag, you were still thinking about 2jz swaps.. 240k miles, I'd definaly consider tossing that engine and putting in a JDM 7mgte w/ ~40k miles.. or you can send your 7mge to the shop, pay them what you'd pay to have a 7mgte dropped in (not including cost of the engine, tranny, tranny swap or combo thereof). Dunno about you, but I'd have much more peace of mind knowing I put something reliable in my car rather than something old and restored to hold together... knowing I got more power out of it would just be an added bonus.
