whoa...guys..take it down a notch, im not sure what all he will come home with, but yes he just wants another opinion of a person he trusts, i personally trust you guys, but my dad is another story...and my guess is that the mechanic sent him to the dealership and/or auto parts store to get some stuff...which explains why the cost is so high, but that also means that the car will be fixed alot sooner as opposed to ordering everything online cheaper then waiting a week while it gets here...ill keep yall posted


well i just got off the phone with my dad and he said he got a new upper, the associated gaskets, and lower gaskets as well as a new serpentine belt, said he spent 270 bucks...i guess my mom was exaggerating a little, she does that alot, so really he didnt get ripped too horribly...honestly i think if we can get ahold of a torque wrench we could at least put it back together tonight...what are the torque specs on the lower intake bolts, upper intake bolts, fuel rail bolts, and any other bolts that are torque sensitive...anyone know? i know i should get a manual, but at this point thats just more money

All the torque specs for the entire car are in Techinfo...it'* really a great resource.

Sounds like things are really looking good for you. For the torque wrench, if you plan on doing a reasonable amount of work yourself. It might be a good time to invest in a nice one. Sears has a couple good ones at reasonable prices. Or possibly rent/free loaner from a local parts store.

the torque specs for the lower intake manifold bolts are not in the techinfo...does anyone happen to have a manual for my particular year? as well as a bolt sequence pattern? i know its a shot in the dark, but maybe?

Hoov, get the book before you go any further.

Torque specs were left out on purpose. Anything critical that you NEED the book for, and any torque-to-yield.

those are just for the upper, at least for my year anyway...

im getting a book tomorrow, as well as a few other things, me and my dad ran out of daylight, we got started about 6 or so and took off the old lower, the gaskets were indeed in pretty bad shape, cleaned everything up good...which leads me to an interesting question...

on the block there were 2 holes, i assume coolant holes, that were clogged with sludge at least an inch deep...the new lower gaskets had holes in them that matched up to the holes on the block...BUT on the lower intake itself there are no holes, we thought there were because there was some sludge on them as well, but they are more or less just depressions in the surface of the intake manifold...they dont go all the way through, its too late for pics now, i should have snapped some earlier...but i thought that was just weird...

anyway we got the new lower gaskets on, hopefully correctly, the instructions were oh so vague, and then we got the manifold back on, i just hope the coolant elbow doesnt decide to go, the seal may or may not be that great, well see when we start it up later i guess...is there a flexible solution to that blasted thing? because i dont really see any way you could install a new one without having to pull the intake back off....

anyway hopefully we shall wrap this all up tomorrow or the next day, time allowing, thanks for all the help again guys, this site is great, ive been here long enough to know that

The replacement for coolant elbows is Series 1.

My 93 has no elbows whatsoever.
