checked my plugs today and found ugliness!!!!

[boost fiend]

ok, i has a weird stumble the last 2-3 days, just as i take off and under boost around 8-13 psi!!! ok, im thinking bad plugs/wires. i take em out to test them all and what do i find???? the gally where the 5 and 6 plug are at is filled with what appears to be oil and coolant!!! clean it all up and regap the plugs to find that the heater hose has been blowing coolant all over the rear of my engine!!!

i about set it on fire today!!!

What can I say, Supras = win.

At least the L shape hose behind/below the water pump didnt blow up on you at 2:30am when you had to work the next day. Now THAT was fun.

you can blame the valve cover gaskets and gravity for the oil...

 

[boost fiend]

cant be any worse than about a week ago when i decoverd that i had a pinhole in my ic. fiancee was driving home in a storm that droped like 12" of rain in a few hours. dumped out like a gal and a half of water, but the engine still lived!!!

all hail the 7m!!!!

Lose the plug galley cover between the valve covers, they cause leaks, and use fipg on the plug threads for those big allen head plugs. You must live on the SE side. That was some wicked flooding.

anythign else to use to better seal the valve cover gaskets? i had a shitload of oil in there and im in the process of fixing (new parts arrive tomorrow yay! )

A good sealing surface, new gaskets, and properly torqued bolts do the trick everytime.

boost fiend,

I feel your pain on the heater hose...coolant got into my clutch assembly but I thought the clutch was thrashed. Pulled the trans, clutch was fine, saw the back of the engine and did the :rant2: :rofl: :cry: routine.

Adding to what Boostedstr8six said, I also put a thin layer of RTV along the sealing surface. Not everyone thinks it's necessary, but it just added that extra peace of mind for me. I also changed the Phillips head bolts to hex bolts so you can torque it down a little better; just don't go crazy with tightening it or the valve cover may crack.

That's what I did, never saw a leak again. Remember though, thin layer.
