car heats up almost instantly

[canonize-ryda]

I just got it back together after replacing the head and adding some performance parts. after the first start it ran for a while and it started to heat up real quick.

This wouldn't be a problem but it goes past the last white notch and heads for the h for hot. I don't think it should be running this hot. (The coolant also gets hot but not as bad as the oil).

Do i need a new thermostat?

Thanks

Once hot exhaust gases start blowing past the head gasket they tend to erode the path wider. A gasket that started out just almost tight enough will soon have a full gap to allow compression to escape.

Check out the old gasket before just assuming that being new means that it's still good.

Good luck.

i figured i would look on the net and find out what size of extention i would need to apply how much torque.

What?WTF Even when calculating these things you have to have a way to know how much Tq your applying in the first place. Then you apply conversions based off of the extention or any other tool you may be using.

Wow. Went downhill fast.

So, you attempted to apply 50ish lbs of Torque, by hand. Now you're over heating. Smells like a problem. Remove the head. Replace the gasket. Replace your fluids. And torque, in the correct sequence from the inside of the head to the outside to 75lbs. I personally use 80, but that is my personal choice. You must also remember that you need to torque, untorque, and retorque. There is a sequence - this sequence must be followed otherwise you end up in the position you are now needing to remove the head again.

Its only ran for a total of maybe 3-4 minutes so hopefully the damage isn't done very badly at this point. And thats may have been my main problem with selftorqueing is i read somewhere 59lbs. Yea i feel like an idiot and don't blame you guys for saying so haha. I have put like 1500 into in performance parts before i even had it running and now this.. Wish me luck

For future reference, the amount of torque required depends on both the type of fasteners you are using (stock bolts, standard ARP studs, L19/A1 studs, etc) as well as which type of lube (30wt oil, moly lube, etc).

Be sure to get the correct torque specs for your situation. Also, composite head gaskets are not re-usable; some MLS gaskets are technically, but that is an on-going debate and matter of opinion.

Turned out to be a blown head gasket. Car is running fine now and heats up normally. I did do a whole rebuild but when removing the head gasket i found it to be soaked threw to one of the coolant/oil jackets holes.

I also got 2 torque wrenches now.. Handy things to have..

 

[jimbob_843]

Wait, you built the motor?????? How did you torque your rod and main bolts?

 

[canonize-ryda]

Notice i said i have 2 torque wrenches. But yea i built my engine.

 

[AlaskanDsm]

I have a feeling that he was referring to when you built the lower end of the engine, what did you use to torque down the bottom end of the engine as opposed to just using the torque wrenches on the head.

 

[mchustle]

I feel a "I threw a rod through my block" thread coming here soon. Lmao jk op. But did you rebuild the bottom end also, because if so and you didn't have a torque wrench I'm sorry to say you will probably be making a thread close to my joke.

 

[canonize-ryda]

No i rebuilt the engine because it was overheating due to not being properly torqued, and i also had some kind of piston slap. I got the torque wrench well before i undertook the rebuild. Anyhow i just chimed in to tell you guys that it runs good now and no overheating issue any more.

Have you thought about going to school for automotive? It seems you have the desire but just need some guidance. There's a procedure for doing thing. You cant just say that's tight enough and call it good. Then there's Torque To Yield (TTY) head bolts, torque angle gauges and all sorts of stuff. You need to be properly trained and it sound s like you would do well. When it comes to engines you cant be guessing. Good luck I hope you don't end up with the "I threw a rod" thread.

I didn't guess on anything.. Its that i didn't use a torque wrench the first time and was also given wrong info. Was told 50 ft lbs when in fact i do 78-80 ft lbs. So i did what i thought was 50 and then found out 80 and then i drove it anyways and overheated cause it had already messed with the head gasket on start up at 50 lbs of torque..

Long story short i rebuilt the engine torqued everything to specs. Now it runs good.. Sounds like you guys are having a problem understanding that when i say i used a torque wrench, that it in fact means i used a torque wrench.

This is a older thread that i was chiming in to tell you that it was in fact the head gasket causing this over heating problem..

I realize this. I am only saying that someone that does what you did has some learning in store. most people would not dare try to do what you did because they know better. You saw how some people didn't even believe you were serious. At bare min. You need a shop manual before you rebuild a motor. I have all data at work and home so I'm spoiled. If you know where to find it and how to do stuff you can have all data too which would be great because you could learn so much about your car and motor that you just wont find in a Chiltons or Haynes crappy manual. I'm trying to encourage you in the right direction bro. I'm a old 35 year old mechanic I'm not trying to give you a hard time, just some advice.

 

[canonize-ryda]

I took it as advice but i thought it threw and realized that i know more about rotary engines than any piston engines. I only used interenet for specs and things like that. I already spun a bearing starting it up the first time. I had mixed the rod caps since i didn't know any better. Yea i do have alot to learn but in the past 4 months dsms have been in my veins i've accomplished and learned quite a bit. I do plan on going to school to be a diesel mechanic once my kids get a little older. I'm 22 and i try to do what i can. Least i didn't choose a honda to drive. I made that one good decision.

Well I say congrats to you sir for a job well done figuring out the issue and not giving up. I am currently needing a new water pump after finding my seep hole in the WP acting like a fire hose with my coolant... *sigh* oh well.

 

[canonize-ryda]

Thanks i appreciate it. And good luck with your project!
