Default Oh, that's what a head gasket looks like

Found this yesterday…PDX240 guided the beastly tear down. But at least we discovered a root of some of my problems.

Indeed…just worried about the noise it was making when it happened. Not sure what noise a blown head gasket will create.

Probably should have done that leak-down test back when the compression figures were a little sketchy in the first two cylinders. A big 'told-ya-so'.

That's the second blown gasket between 1 and 2 I've seen on there in the last couple months... is this a common weak spot?

I love how nice heads look when they come back from the machine shop.
How much do they charge on the left coast to clean, check, and skim a head?
Machine shops are getting scarce in the midway between Baltimore and Washington, DC.

I was referred to Burtonsville Performance Machine by my BMW indy shop and they did a great job on my bare 535i head (the usual cleaning, pressure testing, blasting the ports clean of carbon, cleanup skim) I did the valve lapping myself.

Thanks Steve,
I've used them twice and they happen to be nearby. Yes, they were great. From talking to them, they indicated shops have gone out of business because people don't have engines rebuilt like they used to do. I guess when interference motors bust a timing belt these days, people junk the car or put in a different engine. They said their main customers now days are folks who need engines built for racing.

That's exactly what I am fighting against. I "should" have thrown this car away the day I bought it.

Any thoughts on the "knocking" noise that I was hearing when the head gasket blew out? I just don't want to slam all this back together and hear some lower end terror

eh not likely to be an issue, could have been induced by the cross talk between cylinders. I blew one between 2 and 3 once and thought I'd spun a bearing.

There was another member who blew a headgasket and heard an awful knocking noise as well..I think it went away after he replaced the head gasket
