Mike,

I took some pictures of the canisters over the weekend. Need to bring them into the computer, but it is easy enough to explain.

Each tube from my charcoal canister goes to the fuel tank. I can not see the connection, but the hoses run from the two connectors on the canister and run through the engine bay, disappearing into the fender where the fuel tanks are.

The two smaller canisters are connected to the air boxes and I think the other runs to the fuel tank as well. These smaller canisters are hooked up to a wiring harness and relay. Not sure what this is all about and it looks different from what you have.

Pictures up most likely tomorrow. Wanted to give you a heads up in case you are in a hurry and can figure it out from what I said so far.

Are you interested in the information from my books? The quotes of what the factory was trying to achieve when they built the system?

Ohlgren

Ohlgren,
I would be interested in the information you have in the books, as well as the photos . It is interesting how there seems to be so much variation in all the cars? I guess it depends on which country the car was initially built for, I believe my car was initially sold to Germany.
I have not seen any wiring associated with the cannister, my car could be a little earlier than yours (1984) and maybe earlier emmisions requirements.
Cheers
Mike

Hi Aus
You have done some great work on your Jalpa, Im very impressed.
I have a problem with my friends Jalpa. It looks like you know lots about the engine &
cooling galleries . My friend drove his car the other day & suddenly steam started pumping out the exhaust. He stopped the car & we have not started the engine again.
When i filled the cooling system up i found coolant running out of the exhaust. The sparkplugs are wet. My question is . is there a way coolant can get into the cylinders
from the pump or other galleries or is it a blown head gasket.

Ouch!

Cracked sparkplug hole or blown head gasket! (Both are repairable).

Torro,
I think Ross is correct on this one head gasket most likely, I dont think there is any way the coolant could get into the pistons via the water pump, you may end up with coolant in your oil but not in the pistons. You may like to pull all the plugs then stick a cooling system pressure tester on you may be able to hear which piston(s) is leaking, a compression test may also be helpful at this time to try and isolate all the issues you may have before you strip it down.
Let us know how you go.
Best of Luck
Mike

No question, a broken head gasket, don't turn the engine over any more else heavy damage could occur.

Remove and dismantle the engine asap, coolant in the cylinder will cause corrosion, after a while not only a new gasket but also a cylinder sleeve, piston and ring is to be replaced.

When Frank Sinatra got his Miura S in 1970, he said: “If you wanna be someone, buy Ferrari - If you are someone, you own a Lamborghini”.

Here are the images of what my carbon canister connections are. Still trying to locate the article about the emissions test the system was designed for. I have been through a pile of books with no luck. I will keep looking, but I thought these pictures could show you how a US model is hooked up. The article I am looking for will explain the why.

Image 1 = Canister is mounted to the tension arm of the smog pump. Red arrow shows the hose coming from the far gas tank (red arrow) and the tube going to the closest tank out frame right. The green arrows show the hoses coming out of each air box to a T and then into the smaller canister.

Image 2 = This image shows the hoses leaving the canisters and engine bay to continue into the fender. The opposite side of the engine bay looks the same except the hose goes into the fender near the front.

Image 3 = Shows in green, the hose coming from the air boxes, connecting the two canisters and heading to the fender. This also shows the mess of wiring connected to the smaller canisters. The wiring comes from the cabin and splits in two. One set connects to a little black box on the shock tower. The little box has a red light on top. The other split goes to a relay and then to the two small canisters. No idea what these wires are for.

Image 4 = Better picture of the tubing connected to the smaller canisters.

Image 5 = This is the engine bay, just behind the left hand driver seat. #1 is the after market MSD ignition (I didn't do that messy install) #2 is my fuel filter. #3 is the ignition coil. and #4 is the carbon canister.

I found a diagram on Raymond's Jalpa home page that shows the connection between the carbon canister and the fuel tank. Look at the diagram for the fuel system. If you need help getting to it let me know. Hope this clears up the plumbing questions for you.

Raymond, Aus , Ross,

Thank you for your response,
I agree with the blown head gasket & will do some more tests to confirm.
I will let you know how i go.

No luck on the emission article. I have read the story a couple different places, but I have had no luck finding it again. I get the impression you have plenty to go on. If anyone really wants to see this article I can keep looking. I have a pile of old club news letters, magazines and such. Not as easy to find as I expected.

Ohlgren,
Thanks for the images, as you say with all the info I have got from the site I have plenty to work with . If you cross the emmissions documentation it would be good to see but dont go out of yor way. The emmissions standards in Australia a probably lower than US spec cars.
Thanks for your help
Mike
