Don't you ever do this (Damn fool I am)

[Who]

My supra was covered in oil. I believe it was coming from the cam covers being loose considering that I could turn the philips head screws with my fingers. So I tightened them up and now its time to clean the oil and grit off the engine so I can find source of the oil leak. I grab my trusty degreaser spray and the garden hose. Mind you I was being careful not to clean the entire engine and I used the garden hose sparingly.

Being new to the supra scene I did not realize that the spark plugs ran down the center of the block and make a great space to collect oil and WATER :cry: I start the engine and wow what a misfire. Luckily I had read a previous post about oil collecting in the spark plug wells and causing a misfire so I figured that was my problem. So I started pulling plug wires and removing parts and sure enough, one of the spark plug wells was full of water.

I removed the water and went ahead and cleaned up all the other spark plug wells. Started the engine and the misfire was resolved. Stupid Stupid Stupid. One odd thing is my seatbelt light has come on and it does not go away. Yes my seatbelt is snapped on and I did not have a light until after the cleaning. I will post this as a separate question later. Everything else works! Go ahead kick me in the butt.

Heh. I first did this to myself 15 years ago. I think just about every Supra owner learns this lesson the hard way...

Don't feel bad - lots of us have done it.

I took that damn center plate off, and threw it away.
Now I can clean my engine, when I need to,
grab the shop vac & suck the water right out.
In the 16 years of driving 7Ms,
I have done this to every single one of them.

Also cuts down on the price of good plug wires.
I just buy the universal kits with 'Hemi' plug ends (strait).
They cost half of what you pay for a Supra set.......

The center cover originally had rubber seals around each plug, and had rubber around the outside edge...so if you bought the proper supra plug wires, they would fit perfectly into the cover, and create a leak-tight seal to keep water out...

Best thing to do is to pull the wires out.

LEAVE THE PLUGS IN!

Get a rag/paper towel/air hose and get busy.

 

[DegreE]

Shop vac works well too.


I made a little contraption where I got a rubber hose that will fit in the sparkplug hole and used duct tape to attach it to the vac nozzle so I can fit the rubber hose into the hole and suck the water/oil out.

I'm yet to do this... Fingers crossed I never do!

Sounds like a good idea. My plug wires are OEM. The center plate has a hole in it (factory hole) at the front most spark plug (front of car) under the power pack. It did not keep the water out and the front spark plug well filled up with water. My supra is a 89 turbo so I don't think the straight plug wires would be fitting underneath the power pack.

that center sparkplug valley piece is actually a gasket, there's like composite material on the underside of it. make sure it's sealing well. i didn't want to pay big bucks for replacing it, so i cleaned up the old one, and use "the right stuff" rtv around where it seals. it's been good ever since.

 

[themadhatter]

I've got on just as good, I pulled the plugs out today to check the gap when going a retorque of the headbolts and all the oil that had puddled in the plug vally ran into the cylinders. So when i put every thing back togeather there was more smoke then i thought even posable. Would have put a can of seaform to shame lol

speaking of water in spark plug galley. Whats the best way to remove the water from the cylinder?

Remove all the spark plugs, unplug the fuel pump fuse, crank the starter. It will shoot all over the place.

Make DAMN sure the plugs are out, though!

Yea, the result if you don't isn't pretty:

Also, never do this with fuel. We had a customer who had an injector failure that caused a cylinder to flood with fuel. He decided that doing what I described would clear the cylinders out.

It did... and the vaporized fuel was ignited immediately by the coil packs that he had left piled on top of the intake. (Not the sharpest knife in the drawer this guy...)

Believe it or not, the car did survive.

But it wasn't pretty.

But by removing the fuel pump fuse i wont burn my eyebrows off correct? i just want to make sure when i do this tommorow i dont destroy my motor

It helps to cover the center valley with something like a heavy bath towell. It will absorb most of the "spray".

Yea, pull the fuses. No fuel pump. No spark. You want to kill them both.

alright though this may be annoying and i apologize im going to reitterate what you said one more time.

Remove spark plugs and coil pack. Place heavy bath towel in center valley. Pull fuel pump fuse and coil pack fuse? Crank the car a few times. and clean up im guessing.

 

[87nasupra]

You pretty much got it right. 4-5 cranks should do it. Dont kill your battery over it.:icon_bigg

 

[Poodles]

I wash my engine bay all the time, no issues here...

Don't DUMP water in that area for starters, and if you have the proper plug wires and a good center gasket, it seals VERY well.

 

[JDMMA70]

i did this but when i put everything back together and went to start the car it just click when i turn the ignition is my battery on its way out?
