Blown Head Gasket??

[Dante8910]

I got the turbo installed onto my 96 eagle talon tsi... but where my exhaust manifold connects to the exhaust housing on the turbo theres a metal gasket in between them and right there ive seen oil bubbling. Im thinking its a blown head gasket but then its started also where the wastgate connects to the manifold to.

I havent ran the car at all, i just put the turbo on and was letting it run for maybe not even a 3 mins before ive noticed it and i havent done anything else to it.

If anyone could help id really appreciate it ill put up pics later as to show exactly where it is. Thanks again

Why would it be a blown headgasket if it is leaking oil from the exhaust manifold-turbo gasket. I would check for where the oil leak starts. Could be valve seals in the head causing oil to run into the cylinder or even rings going bad causing blowby. Either way, a headgasket is probably the least likely cause. Pull the exhaust manifold and check the ports inside the head and manifold for oil.

++1 on the valve seals.

Im not for sure as to why it would be a blown head gasket. Im just asking because ive had a couple ppl tell me that it could be that. This is my first time owning a turbo car. Im just trying to figure things out on this car.

First off put the 4th bolt in there to hold the turbo. Then degrease the whole front of the engine and start the car and see where it originates from. Your bubbling is from a missing bolt. Doesn't mean that is where the oil is coming from.

the forth bolt broke off in the housing. What can i do?

 

[bluestreak9999]

Good luck with the broken bolt. They are a nightmare to get out. Easiest way is take it to a machine shop and have them do it.

How about re-tapping to get a bolt to thread into the hole near where his waste-gate is...save for on a 1G? ;P

I noticed that one doesn't go all the way through.

As you can see theres some White Milky shit in there. So im taking it as blown head gasket... any inputs??

 

[Mizzat508]

Are you talking about that liquid in the sparkplug hole? That doesnt look too milky...but it doesnt look too dark either. Anyones guess.

As for the oil leak, all around my exhaust manifold where it meets the head (yes, there is a gasket in there) looks as if its spitting out a little oil, just enough to look messy around the manifold. Would that be typical of an old exhaust mani gasket, or is this a similar problem to Dante's?

 

[Dante8910]

Would a Head Gasket set from advance be ok as a replacement??

How about you do a compression test to see if it is a headgasket then go from there.

 

[hey dude]

You don't have a lot of reason for it to be a head gasket other than someone mentioned it to you. There's not a lot adding up here that it's the head gasket as the #1 cause. Why are you still going down that path right now? Prob just going to go replace the head gasket to find out that you needed a different one.

Check compression, get the bolt fixed, etc.

Theres only Oil and Coolant mixed together in that one section in the picture above. Like ive said this is my first time owning a turbo car.

The oil is bubbling where the gasket is between the exhaust housing and the manifold.

I took the Head cover off and saw there was oil and coolant mixed together. Im not for sure if it is the head gasket or not. but just encase it is at least ill have it. Im just trying to figure it out that way i can get it back up and running.

 

[livedsm4g63]

Oky if you want to know pull the DIPSTICK, and if that is milky then yes. You should do a compression test to verify.

 

[92AWDTalonTSI]

Before you do ANYTHING. Do a compression test. If the test results is a cylinder being under rated or not holding any PSI. Using an air compressor. Fill the cylinder with a small amount of air and listen to where the the air is leaking out.


If you hear the air from the oil passages on the head (With the valve cover removed.) you have either a bad gasket (oil passage leaking into the cylinder) or bad rings (Blow by). It is sometimes hard to tell if the oil rings are bad with just a compression test.

If not maybe the valves.

... If there is oil mixed with coolant.. that is usually a tell-tale sign of ... DUN DUN DUN... Headgasket.

Pull the dipstick, look for coolant. If the oil looks like baby food, again... head-gasket.

Do the simple things first. It doesn't take a genius or $100 in testing equipment to determine if you have a bad head-gasket. IF there is coolant in your oil, then by all means start tearing shit apart.

if you have some random oil find the source, clean out everything
