I turned my car on and let it warm up then turned it off, waited a minute, then ran the exhaust test. Then ran the pressure test. It's a device that sucks up some of the air in the coolant system, which bubbles up through some blue liquid that is supposed to turn yellowish if combustion gases are present.

Do you think it could be too much oil? I think there is about half a quart too much in there right now... I am planning on replacing it anyway because it is dirty.

drowsshap what do you mean by new THB need?

 

throttle body heater

 

I purchased a new throttle body heater and am gonna replace it next weekend. I think that should solve a lot of my problems.

I was looking closely at the engine today, however, and noticed some gunk building up around the headbolts. I attached some pictures. Do you guys think I need to tighten them, or could it be something more serious?

Thanks!

 

tighten your valve covers bolts and clean your engine see if it stops

 

I agree, just looks like a valve cover leak to me.

If your oil is too full I would change it and add the correct amount soon. After you drain and change the filter add 6 qts, start and run about 30 secs to fill the filter, then top off a little at a time until full (about 1/2 qt).

Noticeable coolant loss after driving 2 miles should show up if it is an external leak, I would get your engine cleaned up if replacing your throttle body heater doesn't do the trick so you can look for leaks.

Just curious, is your CEL on?

 

You can't beat being able to pressurize the cooling system more than normal. Those leaks tend to be easy to find, then. I tried one of these :


I found 3 leaks right away.
