Pushing/Burning Coolant, Fresh HG - found problem.

[ziggo0]

Headgasket is a Fel-Pro PermaTorque - it maybe had 600 miles on it. 6 bolt ARP studs/nuts, torqued 30/60/95. Fresh block surface, fresh head surface.

I've had a bit of white smoke here and there, then I started loosing coolant randomly. Was driving through town the other day and saw my temp gauge rise to the top...pulled over, no coolant. I noticed when it's filled up bubbling, rev a little and it wants to shoot out. Pushing coolant - obviously. A WOT pull revealed by a friends eyes blue smoke, mostly on deceleration. It started to get worse so I pulled the head tonight, and this is what I found....

Pretty f'd up huh? I did nothing different with this HG compared to others. I've had plenty of Fel-Pro HGs in the past with zero issues. Defective?

Maybe just some bad luck.

 

[TofastForU_99]

Oops that will do it. Get it fixed GL.

Looks to have hurt #2 as well. Are the fire rings ovalled at all?

I've hurt that gasket the same way for multiple reasons but running strong for quite a while now.

 

[ziggo0]

After cleaning off the block and head, everything looks perfectly fine - no damage into the block or head. The fire ring does appear to be oval'd right there...not entirely sure how/why - perhaps when I put the head on it bumped and caused a slight out of alignment issue. Either way - the car will be back on the road in about a hour and a half to 2 hours - the new headgasket installed very very well - just finished torqueing it down. Ahhh I love ARPs.

I bet the head, or block isn't flat.

Looks like Detonation. Do you have any recent logs?

After re reading the original post, i'd like to change my vote to this. I somehow missed that the head and block were resurfaced, if that is what he means by fresh.

 

[v8killer]

Do you have pics of 1 and 4 also ?

Yea sorry I wasn't more clear. Cyl 1 & 4 looked perfect.. Now that I think about it, when I put that head on I didn't have my arps already in the block - I set the headgasket on the block - set the head on the block - and the headgasket moved so I had to re-do it. Perhaps I pinched the gasket? Or the second mount it still moved. This time I put the arps in...alligned perfectly.

I've been on e85, 20psi, stock timingg - safety rich. Logs no knock.

I'll say user error caused this - probably was in to much of a hurry

 

[v8killer]

Something beat the gasket out,also check to see if your injectors are dirty. It just doesn't look normal!

 

[ziggo0]

They were brand new PTE 1000s 900 miles ago. I'll be doing my hx40 install here in a week or so - I'm going to send them out to be flow tested just to make sure.

Do you have the dowel pins in your block?

 

[Slow91Laser]

Same thing happened to me SAME exact spot gave out on me as well......

 

[DSMReviver]

Did you say you had 600miles on this gasket already when you put it on?

 

[ziggo0]

Do you have the dowel pins in your block?

Yep. They looked a bit worn but not out of shape.

Did you say you had 600miles on this gasket already when you put it on?

I had about 200 miles when I pulled the head to put my new head on. The gasket I'm showing had about 600 miles before i noticed this was going on. It was brand new when I put it on.

That looks like a fel pro composite not a permatorque.

 

[ziggo0]

The part number was for a permatorque unless they are naming things wrong.

Something else, if you look at the pictures I took - I haven't touched the headgasket at all. It looks like it wasn't sitting on the head right to begin with.

 

[Imback]

That's a composite HG

 

[Calan]

That's a composite HG

What he said ^.

The Fel-Pro Permatorque is a coated MLS gasket and looks like this:

Ahh...well, it is AutoZone afterall. So far things have been good with the replacement HG. As I said before, I put the ARPs in, HG down on that - made sure it was on perfectly, placed the head and back together from there.

 

[DSMReviver]

What is your replacement gasket now?

 

[TSIfreek]

Make sure the studs are free in the head bores. Not allowing full clamp force causing the failure . When you put them in with the head on they should go in smooth as glass with no binding on the bore of the cylinder head holes.
