Houston we may have a problem...
 

So blowing headgaskets sucks, Specially when this happens. Do you guys that run 1600cc's have issues with this last cyl running lean?

Re: Houston we may have a problem...
 

Wow, that fucker really let go! Is your head trashed?

Re: Houston we may have a problem...
 

Nope never had a issue with that. What headgasket is that? Looks like a cheapo one. Get a mitsu metal in that thing and some L19's and never have that problem lol.

Re: Houston we may have a problem...
 

Yeah, it had a mitsu metal one in it and that just leaked coolant like a sieve.

Re: Houston we may have a problem...
 

something was warped if it was leaking.

Re: Houston we may have a problem...
 

Is that a normal Felpro or Topline headgasket? Those things blow at 300whp with no knock or anything.

Re: Houston we may have a problem...
 

It's a normal felpro, thought alot of guys ran those with better studs, guess I was wrong. I honestly think something is causing that cyl to be the one to detonate, I just replaced rod bearings cause the rod bearing on that cyl was trashed, luckily I caught it before it threw the rod, but I'm just wondering If anyone has had issues with the last cyl running lean from pressure drop on the fuel rail or anything else like that? Its a stock fuel rail, I have 1600cc inj. with twin 255's, only been using 65-75% duty cycle on the inj though.

The head and block appear to be flat within .002", as best as I can tell with a true straight edge, can't slip paper under anywhere. Of course the heads pretty well junk, maybe weld fill that hole and remachine it but I'm sure it would have even more issues then, and it's already having issues.

Re: Houston we may have a problem...
 

I haven't had any problems like that from 1600s and stock fuel rails. Me and C3lica have run the crappy 1600s on a stock rail maxing out single fuel pump setups with the fuel pressure dropping like crazy.

I have had problems with the cheap non-OEM composite headgaskets blowing for no reason though.

Re: Houston we may have a problem...
 

This is so true!

Re: Houston we may have a problem...
 

Well, I guess you can think of this as a good time to upgrade to a 2g head then :D (Some will say its a downgrade, but I have seen a few cars lose power when going 2g>1g head and gain power when going 1g>2g head. 95tsi on here made 360hp on his 2.0 with a 2g head, switched to a 1g head and a stroker, and lost 13whp. Different setup and all, I know, but he still lost horsepower. I think it's because the 2g head just flows better (not as much in raw airflow, but a smoother air path than a 1g head)

Shane will probably tell you the same thing.

Ic, so as far as MLS gaskets go Fel-pro Permatorque>Cometic>Mitsu MLS right? and machine work is basicly a must for both surfaces?

Re: Houston we may have a problem...
 

I have a head laying around in my basement, its missing some parts, but the casting doesn't have a big relief to the coolant passage so I can probably steal the parts off this head, and run that one.... Or I might just drop in the running 6 bolt in my blue car that ran perfectly fine with this setup and run that... cause I'm broke as a joke right now, and 100-200 for a head gasket + machine work is not gonna fly right now.

Re: Houston we may have a problem...
 

I would just steal the motor from the blue car. That way it won't smoke like a motherf*#@er either :D

123abc blew his headgasket last year the day of the cookout and took a chunk out of the head just like that. if your around rochester i might have a head for ya
