fan's always on...they wired it like that for some reason. but i probably need to check to make sure. i wasn't paying attention to it. hope it didn't die on me. 1st time this happened with this car

 

DAMN didn't you just get this car back from the shop? That sucks...

If the fan is always on and it overheated, there might be air in your system. Did the temp gauge drop down to normal pretty quickly after the overheating? If so, try starting the car and letting it run through a couple of fan cycles with the radiator cap off.

...on second thought, you said they wired the fan to run at all times. Thats not good. Wire it back up the right way and replace your fan switch if the fans aren't working.

 

yeah, just got it back saturday. they wired it to stay on, i haven't the slightest clue as to how to wire it back. not good with wires or wiring diagrams it didn't cool down fast. too like 3-4 minutes. went back and started it and was around 200 and dropped to 196.

 

i would check for air/leaks, or a stuck thermostat.

 

I added liters of water to the radiator, which I thought was weird and I’m down about a quart of oil

 

you need to bleed the system and or look for leaks, This will make a huge diff. Also try to go lean on antifreeze, the heat capacity of ethylene glycol blows next to water. In addition, i would use DI water if u could.

 

Ok, at the moment I should be lean. I’m not leaking coolant, at least when I’m parked there are none. When I drained the coolant and refilled it, I didn’t bleed it, didn’t think I needed to. But I’ll bleed to system and check for any leaks and check my thermostat since I did put in a low temp unit.

what's everyone's opinion on this Mishimoto catch can. I thought there was supposed to be some sort of filter on it to let the gases escape

x 50,000

 

that think looks pricey, go with the endyne one, that what i used an it has the proper fitting.

 

That's a decent catch can. Make sure it has a drain plug on the bottom. I use a similar one in my setup with no problems. I don't understand the need for a filter on top other than to let vapors escape. The can is connected to vacuum at all times and if you have steel wool in the can, the oil in the can should not get back into the motor. In theory...

vacuum all the time? he is boosted there is no vacuum unless you pull the can off the turbo intake, but why would u wanna pull that **** back into the motor?

 

If you don't have it connected to vacuum, then it defeats the purpose and is just something wasting precious engine bay space. When I was boosted I jbwelsed a fitting onto my turbo intake so that I could hook this up right. But with a filter on top of the can, how can there be enough vacuum to suck the pressure/vapor out of the block? The filter thing has always left me "baffled" LOL

 

I dont think catch cans are supposed to have vacuum. I dont know much about them, but IIRC its really just for blow by and old vapor. Once it fills, you drain it. Or.. run a return line back into the block.

 

100% wrong, first off i have one no vac and it fills up, two, it has pressure difference just do to heat, think about it and you will. The hot vapor leaves the block and condenses on the cooler can.

 

This is what I've always gone by but I never knew why there is a filter on top of the CC.

 

I planned on getting the Endyn but there's a lot of different info out there on set-ups

 

This can of worms gets opened every so often.. I think we need to put a final fork in it this time!

I know there is a lot of different set-ups... whats correct?! Turbo set-ups v.s. non turbo set-ups? Is it even necessary if your not Turbo?

Ive never seen any diagram like that B16CRXT.. or even herd of vacuum source being used. I assumed the heat and pressure from the motor is normally alleviated through the nipple by the oil cap and than sent back through the intake to be re-used/clog your **** up, and running a catch can and not rerouting through the intake would simply keep your **** clean and clear.
Turbo's experience a lot more pressure and blow by so that is why I assumed most turbo set-ups were routed back into the block.. or they would be draining can's daily.

Why do some people run 4 lines out of the VC and some only 2?
drag racing/ lines on the back? road racing/ lines on the front?

I know there is another thread JUST for this.. but I think we will get better results amongst ourselves.

 

Drove the car hard during lunch. Temp stayed at 184°. Parked it and while the turbo timer was counting down, it went up to 196°.

 

i run the two back fitting to the endyn setup, no return (i just dump it) no vacuum, no problems, 444whp, nuff said.

 

air in the system man, or faulty thermostat.

 

I’ll change the thermostat and see what happens.

The Endyn set-up that I saw had it venting from the back of the block and draining back. The car was NA, so would this way be the same with a turbo set-up?

 

dont return it, just dupm it. Unless you are making 900whp or your ringlands are ****ed, you wont fill up that fast.

 

Yea they definitely don't fill up quickly. I think I emptied mine out every other oil change and it still wasn't full.

Chemist - How is yours setup? Line from the block to the can and the other line from the VC to the can? Both send vapor into the can? Does yours have a filter on top? If it didn't and this is how it is set up, it seems to me that the top and bottom would be fighting pressure against each other.

What is the proper way to set up a catch can with no filter on top?

 

I have also heard of people welding a fitting down on the exhaust and that would act as a vacuum source to pull pressure out of the crank case...
