Default bent a valve- no broken belts - shop to rebuild head in pnw

car was just started up and running very poorly, then everything freezes.

compression:
130
130
130
5
cylinder number one, gone.

it looks as though it's the exhaust valve, I can see the intake valve and it looks alright (there are a few sediments on the top of the valve though)

now I REALLY don't want to put more money in this car but...
I can't do anything with it not running.

so I'm looking for a good shop to rebuild my head, preferably local.
as cheap as possible, with maybe a few upgrades if their cheap enough.

I called around and am getting about $2000 to $3000 to rebuild it.

I found a guy that would do it for cheaper but I'm not too sure, I want some dude doing it.

here's the kicker:

I called the local dealership (barrier porsche of bellevue) just for giggles
I talked directly to the porsche technician

this is what he said in quote:

me - how much would it to rebuild the head of my 944 turbo?

"this is just an estimate but the last one I did was about $9000"

me - NINE THOUSAND DOLLARS!!!!

"yeah, that's about what it ran on a 928 cab."

me - cab?

"cabriolet"

me - the 928 didn't come in a cabriolet

"well maybe it was the 924 cabriolet, I'm not sure..."

now at this point my rage/sarcasm meter went so far off the scale my brain went into safety mode and ceased communications with the idiot.
I am still in awe.

thanks

Send it LR, $499 + the cost of one exhaust valve + ship.

Eric, as we discussed, do a leakdown before pulling the head! Or at least blow compressed air into the cyl head (#1 TDC) to see where the air is going.

I plan to when I get a hold of the air compressor!
ps I found the vacuum hose unconnected under the throttle body, doh!

lindsey racing has some good head options I'm just not to sure I want to do doing it myself (I can't but a friend might be able to do it) especially in the apartment parking lot

and if I get the head off and find out something was in there and scratched up the walls then I won't know what the hell to do.

Before you do anything, you need to figure out what caused this. Did the timing belt jump a few teeth? Did you drop a bolt in the intake manifold or down in the head that is causing a valve to stick open?

Figure out what the problem is before you start tearing stuff apart.

I agree about finding the cause first!

Lots of places can do good head work, JME, SFR, Broadfoot etc. Depending on what you want out of the head / car. If its performance, keep in mind the LR stage 3 head has been independently flow tested and proven to flow less than stated, similar to their intercooler... refer my Engine Analyzer thread.

I say have a BBQ and head pulling party and see what the damage is before you mentally spend money on parts you may not need and find the cause of the failure!

I'm very curious to know where you got this information from about these vendors and their headwork. Before I posted this response, I went to each vendor's web site, and looked for specific data, CFM, before after charts, anything. First, I just went to the SFR site, and it's headwork link is broken. So where is there public information on their headwork? Next, I visited the JME one, and there isn't anything there at all but prices - nothing regarding any CFM, data, etc. So that's another one with no clear data for a prospective customer before they work with that vendor. If I missed something on these web sites, please point me in that direction for I'd love to learn about their headwork, as I'm sure others would too. Thanks in advance for your guidance and help too, it's always appreciated from someone like yourself whose been a member longer than myself, and with vast amounts of experience on 944Ts.

And by the way, Lindsey happens to be one of the few vendors who happily markets their headwork numbers. I know of 3 people who have the LR Stage 3 head, myself being one; and it was flowed here in NJ and "exceeded" their claimed numbers. I was actually in shock myself and called Lindsey. Very interesting...

Lets deal with your issues:

1) I did not say there was public information, so your reply is to something you made up.
2) I did not say JME had price or CFM data up.
3) Yes LR happens to post their headwork numbers, and it flowed less, as did their IC by an independent party.

As a general note, I did not say nor imply a website needs to exist for products or services to exist. I hope this helps you out some... give JME a call and see if he can whip you up a decent head

Thanks for the advice, but from you NZ, never. So no thanks.

Look at my Engine Analyzer thread... I have tried desperately to get LindseyR to reply to the head spec, but to no avail.

Why don't you link it.
Given history, do you think they'll actually respond to anything you write?
