Head gasket swap ?'s and misc ones.

[TD or Not TD]

I Need to know what tool i need to take the headbolts out. i beleive its a hex tool but there is oil in the valley's and i was too tired to look. plus ill have to purchase the tool.

also i need to know the torque sequence and the stages i need to torque them down too.

and another thing. did anyone see those intake manifolds that a guy was making on e-bay for the CA, i beleive its the same guy that makes the SR/KA mounts for the Corolla. i think he also made ITB's for KA and some other neat things.

thanks in advance for the info! i need to at least get that tool today.

Socket Driver, Metric, Hex, Standard, 10 mm.

Ya i used what he had but it can be difficult at first cause the oil, the hex doesn't want to go into the bolt all the way. I used a 9mm one i had and stuck it in first to get alot of the fluid out, then proceed with the 10mm.

Use a mini sledge hammer to force the 10mm hex into the bolt head. It'll spray all the crap inside all over the place, so be carefull.

If you have a stuck bolt, take a 3/8" extension, put it ontop of the headbolt and strike the extension 1/2/3 times with the mini sledge. It'll loosen the bolt so you can remove it with the hex stocket. I've had some of the 10mm head bolts strip on me. The bang method works!

[themadscientist]

Don't bang anything with a hammer, stop that sillyness before you damage something. Squirt a little WD40 or something like that in the socketholes of the bolts and work a small flathead screwdriver around in there to break up coked up junk. Clean it out with a Q-tip or a rag twisted into a tip. If the bolts are tough get a cheater bar and a solid tool to turn with. Cheap tools explode under the pressure sometimes. DO NOT go banging on your head bolts.

Sounds like someone has never striped a hex headbolt

If you do NOT want to pound on the head bolts, make 100000000000% sure they are CLEAN!!! You need MAXIMUM contact or stripping the hex head is likley!!

If you use a socket extension, make SURE to HOLD THE EXTENSION when you turn the breaker bar, you do NOT want ANY side loads on the hex socket or bolt.

Note, don't whail on the head bolts with a hammer, you can tell when the socket bottoms out inside the hex head bolt.

another note, WD-40 is a water displacement formula (plus it smells good ), use PB blaster..

[themadscientist]

Never stripped one because I don't abuse them. I have broken several sockets and breaker bars though. has anybody found a source of 1/2" drive allen heads? I hear good things about PB Blaster but I don't get it over here. WD works for the crud. I would use something more agressive if it needs it but I have yet to encounter a motor that dirty.

alright thanks for the info.

no comments on torque sequence? pattern and lbs.

[themadscientist]

If nobody has an answer by the time i get home I'll hook you up.

There is a link in the FAQ to down load the Factory Service Manual. (FSM) It contains all of the information that you're after, and you should have a copy regardless. I'll even give you the link...http://www.nicoclub.com/FSM/misc/CA18DE.zip

i have to purchase winrar or winzip to unzip the file but i was able to lookat it and i saw that it states to torque them down to 22lbs then 76lbs then it states "or if an angle wrench is available tighten bolts 85-90 degree's clockwise" is this step neccesary? and does it basically mean to turn the torque wrench a quarter turn extra?

[float_6969]

The bolts stretch. Using an angle wrench is the most accurate way to do it, but you don't HAVE to use one.

Just torque them down like it says and you'll be fine. IIRC it says to loosen them all back up and then tighten them back up again, but I could be wrong. I'm not at home so I can't look it up right now.

[themadscientist]

I always wondered about that. That loosen and re-tighten was with a stock gasket, what about a metal one?

[TD or Not TD]

yeah it did say to tighten and loosen then retighten. but i have another question....

i went to scrape the gasket on the cylinder head and left the washers in the cylinder head because they were in there pretty good so i figured they would stay..... well they all slid into the inner gallley of the engine. i got 9 of them out but i cannot find the other one i dont know if it is stuck or not.... im kind of pee'd off at myself but whats done is done and i need to find that last one. i dont hear it rolling around in the head so i dont even think its in there(it could have fell out while moving the head to the car because one came out the oil return.

[TD or Not TD]

ttt what kind of washer can i use to replace the one that is missing?

[themadscientist]

try fishing around in there with a magnetic retriever.

[TD or Not TD]

i am almost 100% sure it is not in the cylinder head. i sprayed it completely down with brake cleaner to loosen up anything if its stuck in thick oil or sludge and nothing came out so i tapped all around the head with a board hitting the board with a hammer lightly all around. so now my question is. where can i get just one head bolt washer?

[float_6969]

I'll bet it IS in the head. I did the same thing and didn't find it until I removed the cams and lifters. It had wedged under the lip of one of the lifters and wasn't moving around.

If it's still in there, you'll know as soon as you start up the motor and toast one of your lifters.

Ask Tim about it...
